GATA3

Summary: GATA3 acts upstream of reduced epithelial-to-mesenchymal transition through miR573 regulation.

Reason: Selected original PMID:26451614 Results and Methods show GATA3-dependent miR573 promoter activity and occupancy in human cell models, with miR573 antagomir reversing GATA3-associated epithelial-marker and invasion effects. Keep the literal acts_upstream_of relation and this non-core prostate-cancer regulatory setting. GATA3 performs transcriptional work upstream of the EMT phenotype; the work does not establish a universal effect in all epithelia or identify a natural GATA3 product selectively.

Summary: GATA3 establishes T-lineage transcriptional identity beyond its mature Th2 program.

Reason: PMID:2017177 directly establishes human and mouse GATA3 transactivation of the human T-cell receptor delta enhancer. That source alone is not an entire precursor-differentiation experiment, but it supports the lineage-specific mechanism underlying the established T-cell developmental role. Retain the broad T-cell differentiation context without limiting all T-lineage functions to mature Th2 differentiation or claiming that the original enhancer assay directly measured every developmental transition.

Summary: Human GATA3 activates transcription through a T-cell-receptor delta enhancer.

Reason: The original PMID:2017177 abstract explicitly reports that human and murine GATA3 activate transcription through a GATA-binding site in the human T-cell-receptor delta enhancer. The independently inspected human promoter mutagenesis and reporter experiments in PMID:20484083 establish GATA3-dependent transcriptional activation. This is a core regulatory activity. The source relation and the separate curator records remain literal; no claim of a full 1991 Methods reading is made.

Summary: Wild-type GATA3 binds regulatory DNA, with reduced affinity in the HDR-associated Thr272Ile mutant.

Reason: The authentic PMID:19723756 abstract reports wild-type versus mutant EMSA and reporter assays using GATA3 constructs in COS7 cells. It establishes DNA binding but does not expose the exact probe sequence or full original assay protocol. Independent human promoter-site experiments in PMID:19674970 and PMID:20484083 establish sequence-specific RNA polymerase II regulatory-region binding. Refine the broad binding term to existing GO:0000978 while preserving the original source-specific probe limitation.

Proposed replacements: RNA polymerase II cis-regulatory region sequence-specific DNA binding

Summary: GATA3 occupies promoters of genes responding to low-dose X radiation in human keratinocytes.

Reason: Selected complete PMID:19735555 Results and ChIP Methods identify GATA3 occupancy at radiation-responsive promoter regions and GATA consensus-site enrichment. The promoter context plus independently established GATA3 sequence-specific recognition support existing GO:0000978, a verified descendant of the broad cis-regulatory binding term. Not every radiation-responsive transcript is a direct GATA3 target; the paper explicitly distinguishes indirect up-regulated genes.

Proposed replacements: RNA polymerase II cis-regulatory region sequence-specific DNA binding

Summary: GATA3 occupies cis-regulatory regions in primary human helper T cells.

Reason: Recovered original PMID:19805038 reports GATA3 ChIP-chip with two antibodies and multiple donors, with promoter and intragenic peaks at defined target loci. Independent human GATA-site binding experiments establish sequence specificity. Refine the general regulatory-region binding to existing GO:0000978 using its verified is_a path. Shared GATA3/T-bet target peaks do not by themselves prove simultaneous binding: the authors explicitly report failed positive controls for the attempted sequential ChIP.

Proposed replacements: RNA polymerase II cis-regulatory region sequence-specific DNA binding

Summary: GATA3 binds the CDH1 regulatory region and promotes its transcription.

Reason: The inspected original Results of PMID:20189993 report GATA-like motifs in the E-cadherin promoter, reporter responses and a reduction in GATA3 promoter binding after depletion. Independent human promoter-site evidence establishes the whole sequence-specific polymerase II binding claim. Refine the general regulatory DNA binding to existing GO:0000978; the local cache contains substantial Results but not complete original Methods, and figure images were not inspected.

Proposed replacements: RNA polymerase II cis-regulatory region sequence-specific DNA binding

Summary: GATA3 occupies sequence-dependent sites in its own RNA polymerase II promoter.

Reason: PMID:20484083 identifies two GATA sites in the human GATA3 exon1b promoter, tests their joint mutation in reporter assays and measures GATA3 promoter occupancy by ChIP. This supports the already-asserted GO:0000978, a verified is_a descendant of the general regulatory-region-binding term. Refine the binding location and sequence specificity while preserving the original experiment; cooperative recruitment by c-Myb and Menin does not negate GATA3 DNA occupancy.

Proposed replacements: RNA polymerase II cis-regulatory region sequence-specific DNA binding

Summary: The conserved regulatory DNA-binding activity can be specified as cis-regulatory binding.

Reason: The mouse-derived electronic assertion is consistent with human GATA3 binding to T-cell receptor and other promoter/enhancer GATA elements. Existing GO:0000978 is an is_a descendant of the incoming broader polymerase II regulatory-region term and describes the independently established human activity. Preserve the literal ortholog donors; the refinement does not require rejecting the transfer or assuming that electronic evidence is weak.

Proposed replacements: RNA polymerase II cis-regulatory region sequence-specific DNA binding

Summary: GATA3 recognizes GATA sequences in cis-regulatory regions of RNA polymerase II genes.

Reason: The actual PTHR10071 tree places human GATA3 below the PTN001600628 IBD origin without a retained intervening loss assertion. The target itself legitimately contributes experimental donor evidence. Human promoter-site mutagenesis and GATA3 ChIP in PMID:20484083, together with enhancer activation in PMID:2017177, corroborate this conserved core DNA-binding activity. The phylogenetic assertion is evaluated by its placement, not by donor count.

Summary: GATA3 recognizes GATA sequences in polymerase II cis-regulatory DNA.

Reason: The ortholog transfer agrees with direct human GATA3 enhancer binding and promoter-site experiments, including sequence competitors, GATA-site mutations and chromatin occupancy. This is a core molecular activity. Retain the incoming donor-backed assertion separately from the direct human records rather than treating evidence-source repetition as biological error.

Summary: GATA3 binds the GATA-containing regulatory region of the endothelial Tie2 gene.

Reason: Original PMID:19674970 Methods and Results show recombinant GATA3 EMSA with mutant competitors and antibody supershift, followed by HUVEC nuclear-extract EMSA and promoter ChIP. GATA-site mutation and GATA3 depletion reduce reporter expression. This directly supports core sequence-specific RNA polymerase II regulatory DNA binding; the experimental human construct is not assigned to a modern natural isoform without sequence evidence.

Summary: GATA3 is a sequence-specific transcription factor acting at polymerase II genes.

Reason: The InterPro-associated transcription-factor assignment agrees with actual human enhancer binding and reporter transactivation, and with later positive and negative promoter regulation. GATA3 has context-dependent activating and repressing roles, so the general polymerase II transcription-factor activity is a coherent core function rather than an assertion of a single regulatory sign. The domain mapping is corroboration, not the sole basis for the judgment.

Summary: GATA3 is a sequence-specific RNA polymerase II transcription factor with context-dependent activating and repressing roles.

Reason: The intact target sequence and actual descent from the PTN001600628 IBD origin support transfer. Human GATA3 promoter activation in PMID:20484083 and FUT7 repression in PMID:17075044 independently establish the two directions of its transcriptional activity. The RNA polymerase II-specific transcription-factor term captures this combined core mechanism without restricting all GATA3 contexts to one regulatory sign.

Summary: The TFClass assignment correctly places GATA3 among polymerase II DNA-binding transcription factors.

Reason: Human GATA3 binds regulatory GATA motifs and changes transcription in reporter and endogenous-cell experiments. This directly supports the TFClass-derived functional assertion. Retain the literal classification identifier and the general core activity, which encompasses the separately established activation and repression contexts.

Summary: Human GATA3 drives transcription through its own promoter as part of a cooperative transcription complex.

Reason: The inspected PMID:20484083 Methods and Results show full-length GATA3 expression constructs, promoter reporter assays, GATA-site mutagenesis and GATA3 ChIP in human T-cell and 293T systems. Its promoter occupancy and contribution to activation support DNA-binding RNA polymerase II transcription-factor activity. Menin-facilitated assembly with c-Myb is part of the mechanism; the result does not imply GATA3 acts without partners or methylates histones.

Summary: GATA3 sequence recognition occurs at polymerase II cis-regulatory elements.

Reason: The incoming cis-regulatory sequence-specific DNA-binding term is polymerase-unspecified. Human T-cell receptor enhancer and other promoter studies establish the polymerase II context. Refine to existing GO:0000978 through its actual is_a edge to GO:0000987; preserve the mouse ortholog transfer and do not mislabel the parent as polymerase II-specific.

Proposed replacements: RNA polymerase II cis-regulatory region sequence-specific DNA binding

Summary: GATA3 binds GATA motifs controlling the human KLK1 promoter.

Reason: The complete authentic PMID:19232384 abstract reports nuclear-protein EMSA, footprinting and anti-GATA3 supershift in primary human keratinocytes, together with promoter reporters and a dominant-negative GATA3 perturbation. The binding is sequence-dependent and at a polymerase II promoter. Refine to existing GO:0000978 through its verified is_a edge from the broader cis-regulatory sequence-specific binding parent; the exact source constructs are not relabeled as natural isoforms.

Proposed replacements: RNA polymerase II cis-regulatory region sequence-specific DNA binding

Summary: GATA3 engages transcriptional coactivators during promoter regulation.

Reason: The mouse-derived coactivator-binding assertion is independently supported on human GATA3 by the Menin interaction in PMID:20484083. Cell-free translated-protein binding and a cooperative promoter complex establish an informative cofactor relationship. Retain this core mechanistic property without equating Menin with a DNA-binding transcription factor or claiming a purified bacterial binary assay.

Summary: GATA3 has a context-dependent RNA polymerase II transcriptional repressor function.

Reason: PMID:19674970 shows both increased and decreased transcripts after two independent GATA3 siRNAs in HUVEC; those changes alone do not prove direct repression of every affected gene. Independent original PMID:17075044 supplies promoter-level GATA3 repression, HDAC association and reduced polymerase recruitment at FUT7. The whole molecular claim is therefore supported while the endothelial source-specific directness limit remains explicit.

Summary: GATA3 activates transcription from GATA-containing polymerase II regulatory elements.

Reason: The transferred activator activity is directly corroborated by human GATA3 enhancer reporters and promoter gain/loss experiments. It describes a core molecular activity even though GATA3 represses other loci in different complexes. Preserve both the positive activity and the separate repressor annotations rather than making regulatory sign universal.

Summary: GATA3 activates a human T-cell-receptor enhancer containing a GATA-binding site.

Reason: PMID:2017177 explicitly reports activation by human and murine GATA3 through the human T-cell-receptor delta enhancer. This is direct positive support for activator function, corroborated by the independently inspected human GATA3 promoter experiments in PMID:20484083. This original curator record is preserved separately from the other record with the same seed key; the duplicate scientific key does not create or erase evidence.

Summary: GATA3 activates a human T-cell-receptor enhancer containing a GATA-binding site.

Reason: PMID:2017177 explicitly reports activation by human and murine GATA3 through the human T-cell-receptor delta enhancer. This is direct positive support for activator function, corroborated by the independently inspected human GATA3 promoter experiments in PMID:20484083. This original curator record is preserved separately from the other record with the same seed key; the duplicate scientific key does not create or erase evidence.

Summary: Human GATA3 binds a defined GATA motif in T-cell receptor enhancers.

Reason: The authentic PMID:1871134 abstract explicitly identifies a full-length human cDNA, in-vitro translated protein binding to the shared GATA motif in several T-cell receptor enhancers, and corresponding enhancer activity. This positive sequence- and regulatory-context evidence supports existing GO:0000978, whose is_a ancestry to DNA binding was checked. Detailed original Methods remain outside the inspected abstract scope; no modern natural-product identity is inferred from the source phrase full-length.

Proposed replacements: RNA polymerase II cis-regulatory region sequence-specific DNA binding

Summary: The combined electronic mapping describes a genuine polymerase II transcription factor.

Reason: The literal ARBA, InterPro and mouse/rat ortholog inputs are preserved. Independent direct human enhancer and promoter experiments justify specifying the broad transcription-factor activity as existing GO:0000981 through a verified is_a edge. This refinement does not claim that each current rule branch or every donor experiment has been independently re-executed.

Proposed replacements: DNA-binding transcription factor activity, RNA polymerase II-specific

Summary: GATA3 activates RNA polymerase II transcription of KLK1 in a keratinocyte context.

Reason: PMID:19232384 reports human KLK1 promoter binding, enhanced reporter activity after GATA3 introduction into NIH3T3 cells and impaired reporter activity with a dominant-negative GATA3 in human keratinocytes. These assays support the more specific, already asserted polymerase II transcription-factor activity GO:0000981. The use of both human cells and a heterologous fibroblast reporter is explicit; the abstract does not establish all construct sequence details.

Proposed replacements: DNA-binding transcription factor activity, RNA polymerase II-specific

Summary: GATA3 regulates RNA polymerase II transcription through sequence-specific promoter binding.

Reason: The human endothelial Tie2 EMSA, ChIP, GATA-site mutation, reporter and siRNA-rescue experiments in PMID:19674970 establish a specific polymerase II transcription-factor role. Replace the general transcription-factor term with the already asserted GO:0000981, connected by a verified is_a edge. GATA3 regulates expression of the receptor rather than supplying its kinase activity.

Proposed replacements: DNA-binding transcription factor activity, RNA polymerase II-specific

Summary: GATA3 participates in transcriptional regulation of human T-cell target genes.

Reason: Recovered PMID:19805038 maps GATA3 binding in primary human Th1 and Th2 cells; the main functional reconstitution experiment manipulates T-bet in mouse cells, which must not be relabeled as GATA3 rescue. Independent human GATA3 binding and transactivation evidence establishes the whole polymerase II transcription-factor claim. Refine the broad activity to existing GO:0000981 without inflating the source-specific perturbation scope.

Proposed replacements: DNA-binding transcription factor activity, RNA polymerase II-specific

Summary: GATA3 activates a polymerase II transcriptional program associated with epithelial differentiation.

Reason: PMID:20189993 tests GATA3 expression and depletion in breast-cancer cell lines and links CDH1 promoter regulation to epithelial characteristics. The source explicitly describes a443-amino-acid construct derived from MCF7 cells; that length alone is not an independent exact sequence-to-product mapping. Refine general transcription-factor activity to existing GO:0000981, retaining the experimental construct and cell-state limits.

Proposed replacements: DNA-binding transcription factor activity, RNA polymerase II-specific

Summary: GATA3 contributes to RNA polymerase II transcriptional control of IL13 in human T cells.

Reason: The authentic PMID:20368097 abstract describes GATA3 depletion in activated human Hut78 cells, reduced NFAT1 occupancy at the IL13 promoter and reduced IL13 transcript. That experiment is not itself a purified GATA3 DNA-binding assay, but independent human GATA3 promoter-site and occupancy experiments establish the whole transcription-factor claim. Refine the general term to the already asserted polymerase II-specific GO:0000981 while preserving the original IMP source and its indirect occupancy readout.

Proposed replacements: DNA-binding transcription factor activity, RNA polymerase II-specific

Summary: Cloned human GATA3 binds and transactivates the T-cell receptor delta enhancer.

Reason: The authentic PMID:2050118 abstract describes human GATA3 made by in-vitro transcription/translation, WGATAR motif binding and enhancer activation after transfection into HeLa cells. The experimentally supported polymerase II transcriptional activity is more specific than the incoming generic transcription-factor label. Refine to existing GO:0000981; the abstract does not independently identify the exact modern isoform sequence.

Proposed replacements: DNA-binding transcription factor activity, RNA polymerase II-specific

Summary: Human GATA3 is a transcription factor for polymerase II regulatory programs.

Reason: PMID:8088776 establishes the human gene organization and T-cell-specific expression of a genomic construct; those results concern regulation of the GATA3 gene and are not themselves a new assay of every GATA3 protein function. Direct human enhancer and reporter evidence from PMID:2050118 supports the whole transcription-factor claim and its more specific GO:0000981 replacement. Retain the original TAS citation with this source-scope distinction.

Proposed replacements: DNA-binding transcription factor activity, RNA polymerase II-specific

Summary: The traced receptor-binding experiment belongs to ECM1, downstream of GATA3 transcriptional regulation.

Reason: The mouse donor trail cites PMID:21217760. Recovered original Results and Figure 8d explicitly test ECM1 with IL-2 receptor subunits and report association with CD122. Figure 2 instead assays GATA3 control of Ecm1 expression, and the authentic original Supplementary Figure 10 independently separates nuclear GATA3 transcription from secreted ECM1 receptor binding. GO:0005134 denotes physical receptor binding, not transcription of a receptor-binding protein. Remove this source-misattributed orthology transfer while preserving the positive GATA3 regulatory function and original donor fields. This judgment rests on target-specific original experimental text and supplement, not the abstract’s main subject, and makes no universal claim that GATA3 cannot bind receptors. The original supplement and selected main-text scope are documented separately in GATA3-external-evidence.md.

Summary: GATA3 associates with the DNA-binding transcription factor T-bet.

Reason: The PMID:15662016 abstract reports kinase-dependent T-bet/GATA3 interaction that inhibits GATA3 DNA binding; its full experimental organism and construct details were not recovered in this reading. Independent original PMID:17075044 Results document endogenous GATA3/T-bet co-immunoprecipitation in human Jurkat cells and tagged-protein mapping in COS7 cells. Refine the generic binding assertion to the verified descendant GO:0061629 for this transcription-factor partner. The evidence does not justify a universal claim that physical binding inhibits both proteins in every context.

Proposed replacements: RNA polymerase II-specific DNA-binding transcription factor binding

Summary: GATA3 recruits HDAC3 during repression of the FUT7 promoter.

Reason: Original PMID:17075044 Results and Methods show endogenous GATA3-HDAC3 association in human Jurkat extracts, tagged-protein co-immunoprecipitation and GATA3-domain dependence in COS7 cells, linked to FUT7 reporter repression and promoter occupancy. Replace generic protein binding with histone deacetylase binding, a verified is_a descendant. The deacetylase activity belongs to the recruited enzyme; this is not a claim that GATA3 catalyzes deacetylation.

Proposed replacements: histone deacetylase binding

Summary: GATA3 and T-bet associate in a complex controlling the human FUT7 promoter.

Reason: Original PMID:17075044 demonstrates endogenous T-bet/GATA3 co-immunoprecipitation in human Jurkat cells and tagged-protein/domain experiments in COS7 cells. Their promoter-occupancy and transcriptional effects establish a functional transcription-factor interaction context. Refine generic protein binding to the verified descendant GO:0061629 while retaining the original T-bet accession. Reciprocal effects reported for this promoter are not generalized to all GATA3 targets.

Proposed replacements: RNA polymerase II-specific DNA-binding transcription factor binding

Summary: GATA3 associates with HDAC5 in a repressive FUT7 promoter complex.

Reason: Original PMID:17075044 documents endogenous GATA3-HDAC5 association in human Jurkat extracts and the GATA3 KRR-region requirement in tagged-protein experiments. The association accompanies repression of FUT7 transcription. Histone deacetylase binding is the specific supported descendant of protein binding; retaining the binding role does not assign HDAC5 catalytic activity to GATA3 or identify an untested natural GATA3 isoform.

Proposed replacements: histone deacetylase binding

Summary: GATA3 associates with ELF1 to activate the endothelial Tie2 promoter.

Reason: Original PMID:19674970 explicitly uses human GATA3 and ELF1 constructs, tagged co-immunoprecipitation in COS7 cells and endogenous ELF1 immunoprecipitation from HUVEC nuclear extracts. Cooperative Tie2 reporter activation supports the functional transcription-factor partnership. Refine generic protein binding to the already asserted GO:0061629, whose typed ancestry to protein binding is verified. Co-immunoprecipitation is not described as purified binary binding.

Proposed replacements: RNA polymerase II-specific DNA-binding transcription factor binding

Summary: The specific GATA3–ELF2 physical interaction remains unresolved in the inspected source.

Reason: The complete original PMID:19674970 main Methods, Results and textual legends directly assay ELF1 co-immunoprecipitation. NERF2/ELF2 is also discussed and its transcriptional synergy with GATA3 is reported as data not shown, but that result does not itself establish the physical interaction with the literal Q15723 partner. Supplementary experiments and the curator underlying record have not been fully inspected. Preserve the original IPI assertion as undecided, without asserting a paralog error, no interaction, or substituting ELF1.

Summary: GATA3 binds the transcriptional cofactor FOG2 through zinc-finger-dependent interactions.

Reason: PMID:19723756 explicitly reports yeast two-hybrid interaction with FOG2 zinc fingers1 and6 and loss of those interactions in the GATA3 Thr272Ile mutant. FOG2 is a transcriptional cofactor, not itself a sequence-specific DNA-binding transcription factor. Replace bare protein binding with GO:0001221 transcription coregulator binding, whose is_a ancestry to protein binding is verified. The abstract does not establish a uniformly activating or repressing sign, so neither more specific coactivator nor corepressor binding is forced.

Proposed replacements: transcription coregulator binding

Summary: GATA3 binds the transcriptional coactivator Menin in its autoregulatory complex.

Reason: Original PMID:20484083 Methods and Results show Menin-GATA3 association in primary human CD4-cell complexes and positive binding of the in-vitro-translated proteins in a cell-free assay. Menin facilitates the c-Myb/GATA3 complex that activates the GATA3 promoter. This is an informative coactivator-binding role, matching GO:0001223 and its verified is_a ancestry to protein binding. Refine the generic label rather than remove the positive interaction. The cell-free translation system is distinguished from a purified bacterial-protein assay, and Menin is not described as a DNA-binding transcription factor.

Proposed replacements: transcription coactivator binding

Summary: GATA3 binds c-Myb weakly in a binary assay, with substantially stronger association in the presence of Menin.

Reason: Original PMID:20484083 first reports repeated unsuccessful attempts to detect stable direct GATA3-c-Myb binding, then documents a weak binary interaction in the reciprocal assay and a much stronger Menin-facilitated association. Endogenous human CD4-cell co-immunoprecipitation and cooperative promoter activation corroborate their functional partnership. These positive results support refinement to GO:0061629 for binding to a sequence-specific RNA polymerase II transcription factor; the definition imposes no affinity threshold. Retain both the initial negative attempts and the later weak-positive result without presenting the interaction as uniformly strong or independent of Menin.

Proposed replacements: RNA polymerase II-specific DNA-binding transcription factor binding

Summary: The GATA3–PSMA3 screen interaction is positive, but the bare binding term is uninformative.

Reason: The authentic PMID:25416956 interaction workbook records GATA3 and PSMA3 as a positive pair, corroborated by the exact human-protein IntAct yeast-two-hybrid records. These are genuine target-level interaction data. Remove the generic GO:0005515 assertion for lack of informative functional specificity under the binding policy, without denying the interaction or treating PSMA3 association as evidence that GATA3 executes proteasomal degradation. No pair-specific mammalian validation or physiological proteasome role is inferred.

Summary: The ACTN2–GATA3 pair is experimentally positive without a resolved specific GATA3 function.

Reason: The original PMID:25910212 Table S3A directly records wild-type ACTN2 binding to GATA3 by yeast two-hybrid; the inspected ACTN2 mutant entries have different outcomes. The exact human-protein IntAct pair agrees with the positive wild-type record. Remove the uninformative generic protein-binding annotation while retaining that positive interaction and its allele scope. The workbook column reporting presence in the earlier Rolland network is not a mammalian-validation assay, and the interaction alone does not establish a cytoskeletal or mechanical GATA3 role.

Summary: GATA3 recruits the histone methyltransferase G9a in a transcriptional repression complex.

Reason: PMID:26028330 reports a GATA3/G9a/MTA3-NuRD repression program. Exact IntAct target records include direct-pulldown entries in addition to complex-expanded co-immunoprecipitation and chromatin records; the latter are not all independent binary-binding assays. The positive interaction with G9a/EHMT2 supports the informative existing GO:1990226 histone methyltransferase binding, whose is_a edge to protein binding is verified. This assigns binding to GATA3, not G9a catalytic activity. The authentic abstract and detailed curator assay records were inspected; complete original Methods and images remain inaccessible.

Proposed replacements: histone methyltransferase binding

Summary: GATA3 engages the MTA3-containing transcriptional corepressor machinery.

Reason: The authentic PMID:26028330 abstract identifies MTA3-NuRD as part of the GATA3 repression program, and exact human GATA3–MTA3 IntAct records include direct pulldown alongside complex-association assays. This is a corepressor relationship rather than merely an unidentified protein contact. Refine the generic binding assertion to GO:0001222 transcription corepressor binding through its checked is_a ancestry. Do not transfer the partners’ chromatin-modifying catalytic activities to GATA3, generalize every NuRD subunit interaction as binary, or claim that the full original Methods were recovered.

Proposed replacements: transcription corepressor binding

Summary: A tested LCK construct interacts with GATA3, without establishing a specific regulatory role.

Reason: The authentic PMID:26871637 isoform-interaction table records positive GATA3 binding for the source LCK_2 construct, whereas the inspected LCK_1 and LCK_3 entries are negative. Exact IntAct records retain the human GATA3/LCK pair. Remove the uninformative generic binding term while preserving the positive construct-dependent evidence; do not generalize it to every LCK product or map the historical construct label to a present-day natural isoform without sequence evidence. A screen interaction does not alone establish kinase-substrate regulation of GATA3.

Summary: GATA3 binds the transcription factor GCM1 and modulates its transcriptional output.

Reason: Selected original PMID:26899996 Results and Methods demonstrate tagged and endogenous GATA3–GCM1 association, including human trophoblast systems, and a pulldown using immunopurified GATA3 with bacterial GST-GCM1. GATA3 represses GCM1 transactivation without reducing the reported GCM1 DNA-binding activity; the study does not detect GATA3 itself at the tested HtrA4 promoter. Refine to the informative GO:0061629 transcription-factor binding through its actual is_a path. Preserve the distinction between cell-derived material and a fully purified two-protein affinity assay, and do not assign GCM1 target-DNA recognition to GATA3.

Proposed replacements: RNA polymerase II-specific DNA-binding transcription factor binding

Summary: GATA3 associates with HIF1α and supports its transcriptional activity in the tested cancer-cell context.

Reason: Selected original PMID:28263977 Results and Methods report GATA3–HIF1α co-immunoprecipitation, domain-dependent pulldown and context-dependent HIF1α stabilization and target-promoter occupancy. The pulldown uses cell lysate for HIF1α, not a completely purified binary binding system. HIF1α is a DNA-binding transcription-factor component, so the measured association supports GO:0061629 rather than bare protein binding. The study uses a human GATA3 expression clone without independently resolving its modern product sequence; it does not establish the same regulatory outcome in every tissue or cancer.

Proposed replacements: RNA polymerase II-specific DNA-binding transcription factor binding

Summary: The GATA3–FGFR3 yeast interaction is retained as evidence, while the generic functional label is removed.

Reason: The authentic PMID:32814053 NN1.0 table directly contains the FGFR3–GATA3 pair and agrees with the exact positive IntAct records. The screen tests human proteins in yeast. Remove GO:0005515 for insufficient functional specificity, not because the positive pair is false or because the publication title emphasizes neurodegeneration. No pair-specific mammalian validation, FGFR receptor activity or receptor-signaling executor role for GATA3 is established by this screen.

Summary: A GATA3–CHAT interaction is positive, with the literal partner product preserved.

Reason: The original PMID:32814053 NN1.0 table lists CHAT with GATA3, and the corresponding positive IntAct participant is specifically P28329-3. Retain that literal product identifier; a gene-symbol table alone cannot silently replace it with the canonical CHAT sequence. Remove the bare protein-binding annotation as uninformative while preserving the human-protein yeast assay. This does not deny the interaction or assign acetylcholine synthesis to GATA3.

Summary: The GATA-type zinc fingers support zinc-ion binding.

Reason: The incoming InterPro IPR013088 mapping explicitly includes zinc-ion binding, and the current human protein contains this superfamily and two GATA-type zinc fingers. Human GATA3 structural work also characterizes the tandem zinc-finger domain. Retain the structural metal-binding annotation; this does not assert a separate zinc-sensing or catalytic activity.

Summary: GATA3 can form a cooperative homodimer on appropriately arranged DNA sites.

Reason: The actual mouse donor trail identifies PMID:18621058. Recovered original Results and Methods demonstrate direct contacts between two mouse GATA3 C-terminal zinc-finger fragments and cooperative binding of the double-finger fragment to adjacent GATA sites. These support the more specific GO:0042803 protein homodimerization activity through its verified is_a edge to identical protein binding. This is a conditional DNA-associated mode: the same study describes other DNA configurations with a different stoichiometry. Preserve ortholog-transfer and engineered-fragment scope; do not claim an obligate full-length human homodimer or natural splice-product specificity.

Proposed replacements: protein homodimerization activity

Summary: GATA3 sequence-specific DNA recognition has a defined cis-regulatory role.

Reason: The combined ortholog/domain mapping is consistent with human GATA-motif binding, but GO:0043565 omits the established polymerase II cis-regulatory context. Refine to existing GO:0000978 using the checked is_a path. The actual mouse and rat identifiers remain unchanged, and independent human evidence supports the specificity rather than a guessed domain-to-function rule.

Proposed replacements: RNA polymerase II cis-regulatory region sequence-specific DNA binding

Summary: Human GATA3 binds the homeobox transcription factor HHEX in the reported reporter assay.

Reason: The original PMID:15016828 Methods, Figure 1 caption and Results explicitly include human GATA3 amplified from HUVEC cDNA and a positive GATA3–Hex yeast-two-hybrid reporter experiment. This directly supports the informative transcription-factor-binding assertion. Subsequent reciprocal mammalian co-immunoprecipitation, endogenous HUVEC association and KDR functional experiments in that paper focus on GATA2; those results must not be relabeled as GATA3 experiments. Engineered Gal4 fusions do not establish a modern natural-product identity or purified binding affinity.

Summary: GATA3 occurs in a DNA-bound complex at adjacent E-box and GATA motifs, but independent E-box specificity is unresolved.

Reason: Selected complete original PMID:20855495 Results, Figure3 text and Methods show Jurkat nuclear-extract oligonucleotide pull-down on an E-box/GATA composite sequence and on a separate GATA site. The major functional site is the GATA motif at -697, and TAL1-containing complexes are recruited by DNA-bound GATA3. Because the composite oligonucleotide also contains a GATA-like motif and the assay uses nuclear extracts, the inspected evidence does not isolate GATA3 recognition of the CANNTG E-box itself. Retain the source-specific IDA as undecided rather than deny the measured complex or automatically transfer TAL1 specificity to GATA3.

Summary: GATA3 associates with the HMG-box region of LEF1.

Reason: Recovered original PMID:18445004 Methods explicitly introduce tagged human GATA3, and the Results compare LEF1 deletion constructs in HEK293T co-immunoprecipitation assays. Domain deletions support an HMG-box-dependent interaction, although some isolated HMG constructs could not be detected and the assay is not purified-domain biophysics. Mouse T-cell follow-up is distinguished from the human GATA3 construct experiments. Retain this specific binding context as non-core rather than reducing it to generic protein binding.

Summary: The rat-derived histone-methyltransferase interaction needs source-specific resolution.

Reason: The rat A6JLV3 record links this function to IPI evidence from PMID:34694864, whose authentic abstract reports GATA3/KMT2A association. Its detailed interaction assays were not recovered here. Human PMID:20484083 instead distinguishes promoter co-occupancy from an unsuccessful direct GATA3–MLL immunoprecipitation test. Those different contexts do not refute one another, but they do not resolve this human transfer. Preserve the positive donor report and the literal IEA provenance; do not equate shared chromatin occupancy with demonstrated direct binding.

Summary: GATA3 binds sequence-specific double-stranded regulatory DNA.

Reason: The ARBA term is biologically supported by human GATA-motif assays and the GATA3-specific HT-SELEX models in PMID:28473536. Existing GO:0000978 adds a cis-regulatory polymerase II context independently demonstrated in human promoter studies, and its is_a path to GO:1990837 is verified. The SELEX experiment itself is not presented as a chromatin or polymerase assay.

Proposed replacements: RNA polymerase II cis-regulatory region sequence-specific DNA binding

Summary: Target-specific SELEX confirms GATA3 sequence-dependent double-stranded DNA binding.

Reason: Authentic PMID:28473536 Table S1 supplies GATA3 construct sequences and Table S2 reports methylated and unmethylated DNA-selection models for its full-length construct. That sequence exactly matches current P23771-2 after removing the terminal stop marker; the separate extended-domain construct matches a canonical P23771-1 fragment. The incoming GOA record remains isoform-unspecified. Refine to existing GO:0000978 using the actual is_a path and independent human cis-regulatory evidence, without claiming that SELEX alone establishes polymerase II localization or equal behavior of both natural products.

Proposed replacements: RNA polymerase II cis-regulatory region sequence-specific DNA binding

Summary: GATA3 can repress RNA polymerase II transcription by recruiting a repressive promoter complex.

Reason: The actual target descends from the PTN001600628 IBD origin, with no retained loss on its path. Original human-cell experiments in PMID:17075044 show GATA3-dependent FUT7 reporter repression, GATA-site dependence, HDAC3/HDAC5 association and reduced polymerase recruitment. These provide direct mechanistic corroboration for a context-dependent core repressive activity; GATA3 also activates other targets.

Summary: GATA3 helps specify the hair-follicle inner-root-sheath lineage.

Reason: The authentic PMID:12923059 abstract reports that Gata3-null mouse skin fails to generate the inner root sheath and contains progenitors with mixed sheath/hair-shaft markers, with grafting revealing additional lineage defects. These are positive GATA3-dependent fate findings supporting the conserved developmental role as non-core. The newly acquired original selected Results and Methods confirm the null-allele and skin-graft scope; images were not inspected, and no precise human product, irreversible commitment assay or universal cell-fate role is claimed. The original donor IDA and mouse identity remain preserved.

Summary: The type-IV hypersensitivity transfer is not resolved by the available expression study.

Reason: The rat record attributes this term to IEP evidence from PMID:16336837. Its authentic abstract describes delayed-type hypersensitivity followed by increased splenic GATA3 during anterior-chamber-associated immune deviation. The detailed source experiments were not recovered, and this temporal association does not distinguish participation in the inflammatory response from its subsequent suppression or deviation. Retain the original rat/Ensembl inference without asserting a wrong annotation or transferring the previous generic non-core decision automatically.

Summary: The cytokine-regulatory role is resolved into supported IL-4 and IL-5 production terms.

Reason: The authentic mouse donor abstract PMID:11093124 explicitly contrasts GATA3 activation of both IL-4 and IL-5 promoters with SKAT-2’s narrower response. Independent GATA3/Notch and human Th2 expression studies support these cytokine programs. Refine the broad regulation-of-cytokine-production assertion to the already represented positive IL-4 and IL-5 production terms through their checked is_a paths. The donor’s full Methods and exact construct sequences remain uninspected; its focus on SKAT-2 is not evidence that GATA3 was not tested.

Proposed replacements: positive regulation of interleukin-4 production positive regulation of interleukin-5 production

Summary: GATA3 dosage contributes to normal human kidney development.

Reason: PMID:19248180 describes a human de-novo truncating GATA3 variant associated with unilateral renal dysplasia in HDR syndrome. This positive clinical developmental evidence is corroborated mechanistically by the separately read mouse nephric-duct work in PMID:19112489. Keep the kidney-development context as non-core; neither the human case nor the abstract alone identifies a specific renal cellular mechanism or excludes effects on additional organs.

Summary: GATA3 loss of function is associated with renal developmental abnormalities.

Reason: The human HDR case and functional mutant analysis in PMID:19723756 support the developmental phenotype while distinguishing it from the COS7 DNA-binding and reporter assays. Together with independent nephric-duct evidence, kidney development is supported as a non-core physiological context. This separate original record remains intact; a shared term with another case report is not a reason to erase its evidence.

Summary: GATA3 regulates morphogenesis of the embryonic mesonephric duct.

Reason: The actual mouse P23772 donor annotation identifies PMID:16319112. Its authentic abstract reports Gata3 expression in the pro/mesonephric anlage and increased duct cellularity, enhanced proliferation, aberrant elongation and loss of Ret after Gata3 inactivation. These are performed transcriptional developmental functions in a component of the mesonephros, supporting the conserved developmental claim as non-core. Human HDR renal abnormalities alone are not the basis for this judgment. The original full Methods and precise human natural-product equivalence remain unverified.

Summary: GATA3 contributes to development of immune lineages through lineage-specific transcription.

Reason: The immune-system-development IBD is at PTN002560228 on the actual GATA3 lineage; the single mouse donor is legitimate phylogenetic evidence. Human T-cell promoter and differentiation experiments in PMID:20484083 corroborate an immune developmental role. Retain this system-level developmental context as non-core rather than equating it with the molecular transcription activity. A checked path from T-helper2 differentiation to this term was absent, so no unsupported descendant replacement is asserted.

Summary: Aortic-valve-specific morphogenesis remains unresolved within the positive cardiac study.

Reason: The authentic PMID:18955134 abstract reports Gata3-null cardiac malformations and lineage-reporter signal in semilunar valve cusps. It also explicitly states that late LacZ signal does not simply recapitulate current Gata3 transcription. The full valve-specific Results and images were not recovered, so reporter presence and broader outflow defects are not silently promoted to a verified aortic-valve morphogenesis assay. Retain uncertainty for this particular ortholog inference, without denying the genuine cardiac phenotypes or claiming the experimental curator assigned the wrong tissue.

Summary: GATA3 loss disrupts cardiac outflow organization involving the right ventricle.

Reason: The authentic PMID:18955134 abstract reports double-outlet right ventricle after pharmacological extension of Gata3-null mouse embryonic survival, together with abnormal outflow-tract development. This is positive structural phenotype evidence supporting the curator’s right-ventricle morphogenesis context as a non-core ortholog transfer. The experiment does not establish a cardiomyocyte-autonomous mechanism or a human product-specific effect. Full original morphological panels were not inspected, and late LacZ labeling is treated as lineage history rather than ongoing Gata3 expression.

Summary: Ventricular-septal development is affected by GATA3 loss in the mouse model.

Reason: The authentic PMID:18955134 abstract explicitly reports ventricular septal defects in surviving pharmacologically supported Gata3-null embryos. Retain this positive developmental consequence as a non-core ortholog context, with the broader outflow-patterning mechanism and systemic model retained. The evidence does not identify a direct human septal-cell target, a particular natural product, or an independently inspected septal histology panel. It is not based solely on expression of a reporter.

Summary: GATA3 regulates polymerase II transcription with activating and repressing contexts.

Reason: The InterPro-linked broad transcription-regulation assignment is correct but can be specified by the two already asserted, independently supported directional polymerase II terms. Human GATA3 activates its autoregulatory complex and represses FUT7 through a chromatin-associated complex. Both GO:0045944 and GO:0000122 have verified is_a paths to GO:0006355. These are separate context-dependent roles, not simultaneous opposite effects at every target.

Proposed replacements: positive regulation of transcription by RNA polymerase II negative regulation of transcription by RNA polymerase II

Summary: GATA3 has experimentally established positive and negative polymerase II regulatory roles.

Reason: The combined ARBA/InterPro annotation is supported, and the current review already contains both directional activities. Refine the general polymerase II regulation term to existing GO:0045944 and GO:0000122, each a verified direct is_a child. Retain activation in the human GATA3 promoter complex and repression at FUT7 as distinct biological contexts; no automatic rejection of the electronic mapping is implied.

Proposed replacements: positive regulation of transcription by RNA polymerase II negative regulation of transcription by RNA polymerase II

Summary: A defined inflammatory-response context is more informative than the broad defense-response label.

Reason: The authentic PMID:7592673 abstract describes GATA-site-dependent mouse IL-5 promoter activation, not a direct infection-defense assay. Independently, actual Gata3 perturbation in PMID:34644537 establishes a role in the inflammatory response and its resolution after tissue injury. Refine the broad defense-response claim to the already asserted inflammatory response, whose direct is_a edge is verified. Preserve the positive IL-5 regulatory evidence without converting a promoter assay into pathogen-clearance evidence or claiming universal promotion of inflammation.

Proposed replacements: inflammatory response

Summary: GATA3 regulates a macrophage program involved in inflammatory resolution.

Reason: The traced mouse study PMID:34644537 uses Gata3 deletion in Cx3cr1-expressing mononuclear phagocytes and finds impaired IL-33-dependent alternative activation, persistence of inflammatory states and defective clearance after muscle injury. This supports a context-specific role in the inflammatory response, especially its resolution, rather than universal promotion of inflammation. Total infiltrating monocyte/macrophage counts and the IL-4 response are not lost. Retain the human ortholog inference as a non-core tissue-response context; computational motif enrichment is not a direct GATA3 occupancy assay, and neither human-product-specific activity nor universal macrophage behavior was demonstrated.

Summary: GATA3 can provide a transcriptional relay in a developmental signaling response.

Reason: The broad GO definition explicitly includes signal-dependent transcription by specific transcription factors. The traced PMID:16319112 abstract connects Gata3 loss with loss of Ret expression/signaling; selected original PMID:19112489 experiments place Gata3 downstream of beta-catenin and demonstrate a GATA-site-dependent RET regulatory reporter in mouse collecting-duct cells. Retain this broad signaling context as non-core while distinguishing it from specific canonical Wnt or TCR–PI3K–mTOR membership. The RET regulatory fragment is human but the experimental Gata3/cell system is mouse; no receptor or kinase catalytic activity is assigned to GATA3.

Summary: GATA3 supports cell-cycle withdrawal in defined developmental tissues.

Reason: The authentic PMID:16319112 abstract reports increased proliferation after Gata3 loss in the nephric duct. Independently, the recovered mouse lens study PMID:19623612 uses actual BrdU and Ki67 readouts and finds failed cell-cycle withdrawal in posterior fiber cells of systemic Gata3-null embryos rescued from sympathoadrenal lethality. Retain negative regulation of proliferation as a non-core developmental context, not a universal antiproliferative property. The lens paper leaves differentiation-versus-cell-cycle causal ordering unresolved and does not establish direct GATA3 activation of p27/p57 promoters. The human DBH promoter used for rescue does not establish a human GATA3 coding isoform, and lens assay details are not imported into the abstract-only kidney study.

Summary: The traced study establishes male duct abnormalities rather than development of the male gonad.

Reason: The inspected original PMID:19112489 Results and textual Figure2/4 captions describe vas-deferens enlargement following Gata3 deletion in the nephric duct. The GO term specifically concerns the male gonad; the vas deferens is a reproductive duct, not the testis. Mark this source-based gonadal assignment as over-annotated while preserving the genuine male urogenital phenotype and GATA3-dependent nephric-duct program. The study does not establish a direct gonadal mechanism here, and this assessment is not a universal assertion that GATA3 can never influence testis biology. No replacement or new genital-process assertion is manufactured.

No replacement or new genital-process assertion is manufactured.

Summary: The xenobiotic-response inference has positive rat-cell evidence but unresolved human scope.

Reason: The rat donor maps this term to IEP PMID:19428696. Its abstract reports increased GATA-binding activity and nuclear GATA3 in PC-12 cells exposed to valproate, thalidomide or alcohol. This is positive condition-specific expression evidence, so the inherited REMOVE cannot be justified by claiming no response exists. Detailed original experiments and the scope of the human transfer remain unresolved. The observation does not establish xenobiotic metabolism, detoxification or the proposed disease mechanism.

Summary: The cited experiment measures responses to Leishmania, not to a viral stimulus.

Reason: The recovered complete PMID:20583921 original Methods, Results and all six textual figure captions describe human PBMC exposure to live L.panamensis promastigotes, clinical leishmaniasis groups and cytokine-polarization controls. The viral-response term requires a viral stimulus; this source does not supply one. HIV testing appears as a participant-screening criterion, not a viral-response experiment. Remove this source-specific IEP assertion while preserving the genuine GATA3 expression findings and without claiming that GATA3 never responds to viruses. No replacement process is manufactured.

Summary: Nephric-duct morphogenesis gives a supported specific context for the broad morphogenesis assertion.

Reason: Human GATA3 loss-of-function genetics supports developmental abnormalities, and the inspected mouse Gata3 perturbation study PMID:19112489 establishes a specific role in nephric-duct morphogenesis. Refine the broad anatomical-structure morphogenesis label to the already asserted nephric-duct morphogenesis through its verified is_a path. The human HDR source is corroborating genetics, not itself a complete nephric-duct assay, and this refinement does not erase the protein’s other developmental roles. The electronic rule’s complete condition tree is not independently audited here.

Proposed replacements: nephric duct morphogenesis

Summary: Nephric-duct morphogenesis gives a supported specific context for the broad morphogenesis assertion.

Reason: The human HDR study PMID:10935639 supports GATA3-dependent organ development; the inspected mouse Gata3 perturbation study PMID:19112489 supplies the more specific nephric-duct morphogenesis context. Refine the broad morphogenesis label through the actual is_a path to that already asserted term. Do not describe the human clinical study as a direct nephric-duct experiment or imply that this selected refinement exhausts GATA3 developmental biology.

Proposed replacements: nephric duct morphogenesis

Summary: GATA3 sustains Ang1–Tie2-dependent PI3K–AKT signaling through receptor expression.

Reason: In human endothelial cells, PMID:19674970 links GATA3 binding and activation of the Tie2 promoter to Ang1-induced AKT phosphorylation; GATA3 knockdown attenuates that response while VEGF responses are retained. Refine the general positive-signaling term to the already asserted GO:0051897 through the verified is_a path. This is regulation through transcriptional maintenance of receptor availability, not direct phosphorylation by GATA3.

Proposed replacements: positive regulation of phosphatidylinositol 3-kinase/protein kinase B signal transduction

Summary: The radiation-response inference remains bounded by its rat expression source.

Reason: The donor record identifies IEP PMID:19084914. Its authentic abstract reports a Th2-like expression profile, including GATA3, after fractionated colorectal irradiation in rats. The attempted original routes did not recover the full experimental text. That positive expression observation is preserved, but it does not establish a human GATA3 DNA-repair mechanism or settle the extent of cross-species response conservation. Retain the source and electronic relationship as unresolved rather than converting an expression marker into a core radiation-response activity.

Summary: GATA3 regulates transcription rather than providing an unspecified gene-expression function.

Reason: The traced PMID:27208706 abstract reports enrichment of putative Gata3 targets after MafB loss, not a fully inspected GATA3-specific perturbation assay. Independent human experiments directly establish GATA3 activation and repression of RNA-polymerase-II target transcription. Replace the vague gene-expression role with those already represented regulatory processes. This is a semantic correction of the functional role, not an is_a/part_of refinement: the checked ontology queries return no such ancestry between the regulation terms and gene expression. No RNA-polymerase catalytic activity or uninspected MafB-study experiment is attributed to GATA3.

Proposed replacements: positive regulation of transcription by RNA polymerase II negative regulation of transcription by RNA polymerase II

Summary: GATA3 supports Ang1-stimulated migration of human endothelial cells.

Reason: Original PMID:19674970 uses GATA3 siRNA and a modified Boyden-chamber assay in HUVEC. Ang1-induced migration is lost after depletion, whereas VEGF-induced migration remains; promoter binding and receptor-expression experiments identify a regulatory route through Tie2. Keep this source-specific endothelial behavior as non-core, rather than claim GATA3 is a motility-machine component or that the effect applies to every migration stimulus.

Summary: Supported T-helper and macrophage contexts refine the generic cell-differentiation term.

Reason: GATA3 controls specific lineage transcriptional programs, including Th2 differentiation and IL-33-dependent macrophage-state differentiation. These already asserted terms have verified is_a paths to cell differentiation and provide informative supported replacements. The macrophage effect is context dependent and does not imply loss of every macrophage lineage; other epithelial roles remain represented separately. This whole-claim assessment relies on primary evidence rather than an independent audit of every ARBA00027429 condition.

Proposed replacements: T-helper 2 cell differentiation macrophage differentiation

Summary: GATA3 supports IL-33-dependent differentiation toward a resolving macrophage state.

Reason: Actual mouse Gata3 deletion selectively disrupts the IL-33-induced alternatively activated macrophage program in PMID:34644537, supported by marker, protein and functional phagocytosis readouts together with in vivo cell-state data. This is positive differentiation/polarization evidence, not merely a count of macrophages: overall infiltration and IL-4-driven alternative activation remain intact. Retain the broad macrophage-differentiation assertion as a non-core ortholog context, limited to the tested transition rather than a requirement for every macrophage lineage. Single-cell trajectories are inferred and do not independently prove all direct transcriptional targets.

Single-cell trajectories are inferred and do not independently prove all direct transcriptional targets.

Summary: The inherited epithelial-differentiation role is supported without conflating epithelial lineages.

Reason: Actual PAINT tree and alignment replay places human GATA3 below the asserted PTN002560228 origin, with the literal mouse descendant evidence retained and no target-path loss identified. Independent skin and nephric-duct studies support regulation of epithelial cell-state differentiation. Keep this non-core ancestral process rather than challenge a valid placement by donor count or replace it with nephron-tubule differentiation: collecting-duct/nephric-duct and nephron lineages are not interchangeable, and the latter source-specific refinement remains unresolved.

Summary: GATA3 translation is an output of mTOR signaling in the traced T-cell study.

Reason: The actual mouse donor source PMID:20696860 uses rapamycin and translation measurements to show that mTOR activity promotes GATA3 protein synthesis and subsequent Th2 differentiation. The inspected Methods and Results do not manipulate GATA3 to demonstrate execution or feedback propagation of TOR-mediated molecular signals. Mark this pathway-membership assertion as over-annotated while retaining the positive pathway-dependent GATA3 biology. This is a source-specific distinction between the regulated output and the signaling process, not a claim that transcription factors can never participate in signaling or that GATA3 has no feedback role in any context. The literal human ortholog inference remains preserved.

The literal human ortholog inference remains preserved.

Summary: GATA3 promotes IL13 production through its transcriptional regulatory context.

Reason: PMID:20368097 explicitly reports reduced IL13 transcription after GATA3 siRNA in anti-CD3/CD28-stimulated human Hut78 cells, accompanied by reduced NFAT1 promoter occupancy. This supports positive regulation of the named cytokine in the tested human T-cell setting. Keep this specific downstream immune output as non-core rather than treating GATA3 as IL13 itself or assuming an unmeasured direct binary interaction.

Summary: GATA3 increases IL13 secretion from the tested human Th2 cells.

Reason: The recovered PMID:20554961 Methods and Figure4 Results compare GATA3-GFP with control retrovirus in sorted primary human CD4 cells and measure increased IL13 secretion. IFN-alpha suppresses the response even with ectopic GATA3. Retain positive regulation of this downstream cytokine as non-core, with the human culture setting and interferon modulation explicit.

Summary: GATA3 supports IL-4 production in the T-helper regulatory program.

Reason: The authentic PMID:17658278 abstract reports that Notch-mediated IL-4 expression requires GATA3 and that GATA3 and Notch act in parallel to enhance IL-4 expression. This is positive GATA3-specific regulatory evidence supporting the mouse-to-human ortholog annotation as a non-core cytokine context. Full original Methods and construct sequences were not recovered in this reading, so no precise human isoform, purified mechanism or universal requirement across cytokine conditions is claimed.

Summary: GATA3 promotes IL5 production in a human Th2-cell setting.

Reason: Original PMID:20554961 retroviral-transduction Methods and Figure4 Results show increased IL5 secretion from GATA3-expressing primary human CD4 cells relative to control. The response is inhibited by IFN-alpha and is not equated with GATA3 having cytokine activity. Keep this specific immune output as non-core.

Summary: The precise mammary epithelial proliferation assay remains unresolved.

Reason: PMID:19483726 reports reduced primary tumor outgrowth and lung metastatic expansion after GATA3 expression. These positive findings do not alone identify a direct cell-proliferation readout or distinguish proliferation from survival and dissemination. The publisher route provides the authentic abstract and bibliography but not the original Methods/Results, so the source-specific IDA claim remains undecided. This does not deny the reported tumor-suppressive effects or infer that no supporting assay exists.

Summary: Human Th2-cell GATA3 expression decreases in response to interferon alpha.

Reason: Original PMID:20554961 directly measures GATA3 RNA and protein under IFN-alpha treatment in primary human CD4-cell cultures, including committed Th2 cells and ectopic GATA3 conditions. A stimulus-dependent decrease satisfies the response term. Retain the IEP claim as non-core and distinguish the reported human response from the paper’s contrasting mouse observations.

Summary: GATA3 regulates the sympathetic noradrenergic program rather than catalyzing norepinephrine synthesis.

Reason: The actual mouse donor cites PMID:10835639. Its authentic abstract reports decreased Th and Dbh transcripts and noradrenaline in Gata3-null embryos, with partial rescue by feeding catechol intermediates to pregnant dams. This supports transcriptional control of the enzyme program and the physiological importance of its output. GO:0042421 describes the chemical reactions and pathways forming norepinephrine; the reported GATA3 function is upstream regulation, whereas TH and DBH perform the biosynthetic chemistry. The transferred biosynthetic-process assignment therefore overstates that function. This does not deny the phenotype, assert that the full original lacks another assay, or invent a specific regulatory replacement. The later conditional study distinguishes sympathetic-neuron survival from early differentiation.

Summary: PI3K signaling regulates GATA3 abundance without establishing GATA3 as a PI3K–Akt cassette component.

Reason: In the traced mouse study PMID:20696860, PI3K inhibition reduces GATA3 translation relative to control proteins; GATA3 is the measured downstream product. The current GO definition describes the intracellular cassette from PI3K activation through PKB/Akt activation. No inspected GATA3 manipulation demonstrates execution of that cassette. Mark the specific pathway assertion as over-annotated while preserving the genuine downstream Th2 response. GATA3 can regulate signaling competence transcriptionally in other settings, but that does not convert this experiment into proof of GATA3 participating in the defined PI3K–Akt cassette.

Summary: GATA3 dosage is important for development of the human auditory system.

Reason: PMID:19248180 reports bilateral sensorineural deafness with a de-novo truncating GATA3 variant in a patient with HDR syndrome. Independent human HDR evidence in PMID:10935639 supports the auditory developmental relationship. Retain this organ-level context as non-core without pretending that the case report provides a developmental time course, a particular ear-cell assay or a natural-isoform comparison.

Summary: GATA3 dysfunction contributes to the auditory-development phenotype of HDR syndrome.

Reason: PMID:19723756 identifies a human HDR-associated GATA3 mutant and reports reduced DNA binding, FOG2 interaction and transcriptional activity. The clinical auditory phenotype, with independent HDR evidence, supports ear development as a non-core context. Full original clinical details were not recovered; the molecular assays do not themselves measure cochlear differentiation.

Summary: Estrogen-receptor-associated GATA3 expression is not yet resolved as an estrogen-stimulus response.

Reason: The authentic PMID:10037815 abstract compares estrogen-receptor-positive and negative breast-cell lines and identifies higher GATA3 RNA in the former. It does not describe an estrogen exposure or hormone-response time course. The attempted original PMC route returned a browser challenge rather than full Methods/Results. Preserve the original IEP assertion as undecided rather than treating receptor status as the stimulus or claiming that GATA3 cannot respond to estrogen.

Summary: GATA3 participates in the transcriptional program establishing and maintaining human Th2 cells.

Reason: PMID:20484083 examines primary naive and effector/memory human CD4 cells under Th2-promoting conditions. GATA3 occupies and helps activate its own promoter, with c-Myb and Menin enabling the autoregulatory complex; the resulting expression program accompanies Th2 differentiation and maintenance. GATA3 performs transcriptional work in the process, rather than merely being an expression marker. This well-established immune-lineage function is retained as a core physiological context, with the study’s c-Myb perturbation design and cell-culture scope explicit.

Summary: GATA3 helps establish lineage-specific cell fates through context-dependent regulatory programs.

Reason: Human GATA3 descends from the PTN000800998 ancestral commitment assertion without a retained target-path loss. Human Th-cell studies in PMID:19805038 and PMID:20484083 support opposing lineage programs and GATA3 autoregulation, while the inherited assertion encompasses developmental fate decisions beyond a single cytokine readout. Retain the commitment context as non-core; differentiation and commitment are not treated as interchangeable terms, and no unverified typed replacement or universal irreversibility assay is claimed.

Summary: The ethanol-response transfer remains source- and species-limited.

Reason: Rat IEP PMID:19428696 reports increased nuclear GATA3 after alcohol exposure in the PC-12 model. The available abstract therefore gives positive evidence of a response; the older removal should not be carried over as though no evidence existed. Original dose, time-course and mechanistic details were not inspected, and human response conservation is not independently established here. Preserve the inference as unresolved without implying that GATA3 metabolizes ethanol or that this assay establishes disease causation.

Summary: GATA3 promotes a T-cell differentiation program through lineage-specific transcription.

Reason: The positive regulatory claim is biologically supported by GATA3-dependent T-cell transcription and Th2 cytokine-program evidence, including human GATA3 transactivation and ectopic-expression studies. The traced mouse PMID:20696860 study connects GATA3 abundance to Th2 differentiation but manipulates upstream signals, so it is not represented as a direct GATA3 loss/rescue experiment. Retain the broad positive regulatory process as a non-core lineage context, with independent evidence distinguished from the source-specific signaling experiment. Positive regulation of differentiation is not the same ontology relation as the separately retained Th2 differentiation process, and no unverified descendant or new regulatory annotation is manufactured.

Positive regulation of differentiation is not the same ontology relation as the separately retained Th2 differentiation process, and no unverified descendant or new regulatory annotation is manufactured.

Summary: A cell-cycle mechanism is not resolved by the inspected breast-cancer experiments.

Reason: PMID:20189993 reports smaller xenograft tumors and altered epithelial/invasive behavior, but its Results also state that cell proliferation did not differ significantly between control and GATA3-expressing cells in the cited in-vitro test. Tumor size is not by itself a measure of progression through the cell cycle. Full Methods and the relevant supplementary proliferation data remain unrecovered after preserved PMC/BioC access failures. Keep this original IMP annotation undecided rather than infer a cell-cycle block or claim the entire biological function is disproven.

Summary: GATA3 negatively regulates transcription of selected RNA polymerase II genes.

Reason: The original endothelial study detects transcripts induced after GATA3 depletion but does not establish direct binding at each repressed locus. Independent PMID:17075044 establishes promoter-dependent repression and reduced polymerase recruitment at human FUT7. The supported molecular process is therefore the already asserted polymerase II-specific negative-regulation term, a verified is_a descendant of this general parent. Source-specific uncertainty about individual endothelial targets remains.

Proposed replacements: negative regulation of transcription by RNA polymerase II

Summary: RNA-polymerase-II transcription is the supported scope of GATA3-mediated activation.

Reason: The authentic donor PMID:20636338 abstract describes GATA3-dependent Th2 cytokine transcription and MTA2-dependent modulation, while independent human GATA3 enhancer experiments directly establish transactivation. Refine the general DNA-templated transcription activation term to the already asserted positive regulation of RNA-polymerase-II transcription through the verified direct is_a edge. The same GATA3/MTA2 study also reports repression at ifng; this positive annotation does not imply that every GATA3 target is activated. Full donor Methods and exact product identity remain uninspected.

Proposed replacements: positive regulation of transcription by RNA polymerase II

Summary: RNA polymerase II transcriptional activation is the supported specific process.

Reason: The actual ARBA00029082 rule includes a branch requiring IPR000679, IPR039355 and Haplorrhini, all present for human GATA3. The general positive-transcription inference is therefore biologically consistent. Human promoter and primary-cell evidence supports the more informative RNA polymerase II process. Use GO:0045944, an officially verified is_a child of GO:0045893, while retaining the original ARBA provenance. This is refinement of an existing annotation, not a NEW proposal.

Proposed replacements: positive regulation of transcription by RNA polymerase II

Summary: GATA3 activates RNA polymerase II transcription of endothelial Tie2.

Reason: PMID:19674970 supplies GATA3 promoter occupancy, sequence-dependent reporter activation, knockdown and siRNA-resistant rescue of Tie2 expression in human endothelial cells. Refine the general positive-transcription annotation to the existing polymerase II-specific descendant GO:0045944. Positive transcriptional regulation is a core activity even though the Tie2 physiological setting is one tissue-specific application.

Proposed replacements: positive regulation of transcription by RNA polymerase II

Summary: GATA3 positively regulates transcription through its DNA-binding and cofactor functions.

Reason: The PMID:19723756 abstract reports that the HDR-associated mutant decreases reporter transcription compared with wild-type GATA3. Independent human promoter experiments establish the relevant RNA polymerase II mechanism. Refine the general positive-transcription term to existing GO:0045944 using its verified is_a edge, retaining the original mutant-phenotype evidence and the unrecovered detailed reporter architecture.

Proposed replacements: positive regulation of transcription by RNA polymerase II

Summary: GATA3 positively regulates polymerase II transcription in defined human cell contexts.

Reason: The recovered PMID:19805038 main text directly maps GATA3 regulatory occupancy, while its reconstitution experiments primarily test T-bet. Independent human GATA3 promoter activation establishes the positive-transcription claim. Refine the general positive DNA-templated transcription term to existing GO:0045944 along its verified is_a edge, retaining the difference between source occupancy and direct GATA3 perturbation evidence.

Proposed replacements: positive regulation of transcription by RNA polymerase II

Summary: GATA3 positively regulates RNA polymerase II transcription of IL13.

Reason: The source abstract reports GATA3 knockdown, reduced NFAT1 occupancy and decreased IL13 transcript in activated human T cells. Together with independently established GATA3 promoter regulation, this supports the already asserted GO:0045944 rather than the general DNA-templated-transcription parent. The typed is_a refinement does not change the original IMP relation or imply all promoter occupancy is autonomous GATA3 binding.

Proposed replacements: positive regulation of transcription by RNA polymerase II

Summary: Positive regulation of RNA-polymerase-II target transcription is a core GATA3 mechanism.

Reason: Human GATA3 directly transactivates a cognate T-cell enhancer in PMID:2017177 and participates in the inspected target-promoter and transcription-complex studies. This independently supports the literal mouse-derived annotation as a core activity. The broader donor bibliography is not represented as entirely reread, and evidence for activation is not generalized to the separate targets that GATA3 represses. No natural-product specificity is inferred from historical clone labels.

Summary: GATA3 positively regulates RNA polymerase II transcription at responsive promoters and enhancers.

Reason: The actual target inherits the PTN001600628 positive-transcription IBD; its own experimental annotations legitimately occur among donor evidence. Human reporter and promoter-site experiments in PMID:2017177 and PMID:20484083 directly support this core activity. The incoming donor set omits one zebrafish donor found in the later retained IBD/main PAINT version; both source versions are preserved, and the difference does not invalidate the actual target placement.

Summary: Positive regulation of RNA polymerase II transcription is a central GATA3 activity.

Reason: The rat donor record contains direct transcription evidence, and human PMID:20484083 independently supports promoter-dependent activation with GATA-site controls. Keep this core regulatory process. The current rat QuickGO snapshot additionally contains a human-derived electronic annotation; that reciprocal record is not independent experimental support, and it does not negate the separately grounded biology. No new direct-assay evidence code or natural-isoform assignment is substituted for the incoming IEA.

Summary: GATA3 positively regulates KLK1 promoter transcription.

Reason: The authentic source abstract describes GATA-site-containing promoter fragments, GATA3 supershift and gain- and dominant-negative reporter experiments. These are direct positive support for GATA3-dependent polymerase II transcriptional regulation. Retain this core activity with the human keratinocyte and heterologous NIH3T3 assay contexts distinguished; no kallikrein enzymatic activity is assigned to GATA3.

Summary: GATA3 activates transcription through a GATA site in the human T-cell-receptor delta enhancer.

Reason: The original PMID:2017177 abstract explicitly describes transcriptional activation by human and murine GATA3 at the human enhancer, with independent human promoter-level corroboration in PMID:20484083. Positive RNA polymerase II transcriptional regulation is a core GATA3 function. This original relation-specific record remains separate from other annotations drawn from the same publication.

Summary: GATA3 promotes E-cadherin transcription in the tested human breast-cancer cells.

Reason: Selected original PMID:20189993 Results describe CDH1 promoter reporters, GATA-like motifs and GATA3 gain/loss experiments. Positive polymerase II transcriptional regulation is a core molecular role, while the breast-cancer and epithelial-state effects are context-dependent. Promoter activation is retained without treating tumor suppression as universal across all tissues.

Summary: GATA3 participates in positive autoregulation of its own promoter.

Reason: Original PMID:20484083 promoter mutagenesis and ChIP show GATA3 occupancy and contribution to activation of the human GATA3 exon1b promoter. c-Myb depletion prevents occupancy even after GATA3 expression is restored, and Menin facilitates complex assembly. These experiments support positive autoregulation without implying an autonomous GATA3-only reaction. The original has_input P23771 extension is retained literally and is not replaced by an invented DNA or transcript identifier.

Summary: GATA3 contributes to activation of the human NKX3.1 promoter in a TAL1-containing complex.

Reason: PMID:20855495 directly assays human T-ALL cell lines: GATA3 promoter occupancy, GATA-site reporter mutagenesis and GATA3 knockdown support recruitment of the TAL1-LMO-Ldb1 regulatory complex and NKX3.1 transcription. This establishes a core positive polymerase II regulatory capability in a disease-specific context. It does not imply GATA3 alone catalyzes the associated histone changes or that the human regulatory sequence is conserved in mouse.

Summary: GATA3 contributes to sympathetic neuron development through a lineage-specific transcription-factor network.

Reason: The actual P23772 donor cites PMID:15329349. Its authentic abstract distinguishes chick Gata2 from mouse Gata3 and places these factors in the network controlling sympathetic neuronal differentiation. Loss-of-function reduces sympathetic-chain size and noradrenergic-marker expression; the chick ectopic-expression result also shows dependence on lineage cofactors. Together with the Gata3-null and later conditional mouse studies, this supports a conserved developmental role without relabeling chick Gata2 experiments as direct human GATA3 tests or implying uniform regulation at every developmental stage. Retain this specialized developmental context as non-core.

Summary: GATA3 contributes to embryonic organ formation through tissue-specific transcriptional regulation.

Reason: The PTN002560228 organ-development IBD lies on the actual human GATA3 path. Human HDR evidence in PMID:10935639 and the inspected embryonic nephric-duct experiments in mouse PMID:19112489 corroborate organogenesis roles, with species and loss-of-function scope preserved. Retain the embryonic context as non-core rather than representing every organ phenotype as a separate molecular core. Checked nephric-duct and mesonephros paths did not establish descendants of this exact term, so no guessed ontology refinement is imposed.

Summary: Ureteric-bud formation provides a supported specific structure-formation context.

Reason: The traced nephric-duct work and the inspected conditional mouse study PMID:19112489 establish control of the site and success of ureteric-bud formation. Refine the broad anatomical structure-formation label to the already asserted ureteric-bud formation through its verified is_a ancestry. Preserve the distinction between failed normal bud formation and ectopic budding by remaining Gata3-positive cells; the study is not proof that every morphological consequence is a direct cell-autonomous GATA3 function.

Proposed replacements: ureteric bud formation

Summary: Kidney and immune-system development are supported specific contexts of the broad system-development prediction.

Reason: Human developmental genetics, mouse renal perturbation and GATA3-dependent T-lineage transcription provide specific biological support for kidney and immune-system development. These already asserted contexts refine the broad system-development term. The actual ontology route for kidney development includes part_of renal-system development, whereas immune-system development has a direct is_a edge; these relation types are retained rather than called identical ancestry. The complete ARBA rule-condition tree was not independently audited.

Proposed replacements: kidney development immune system development

Summary: GATA3 supports an anti-inflammatory Ang1–Tie2 response in human endothelial cells.

Reason: Original PMID:19674970 shows that GATA3 depletion prevents Ang1 from suppressing VEGF-induced VCAM1 expression and U937 monocyte adhesion to HUVEC; siRNA-resistant GATA3 rescues the expression phenotype. These assays support this limited negative inflammatory-regulation context through receptor-expression control. They do not establish a universal anti-inflammatory role for GATA3 or an in-vivo treatment effect.

Summary: Positive control of ureteric-bud formation specifies a supported developmental regulatory role.

Reason: The inspected conditional mouse study PMID:19112489 establishes a Gata3-dependent regulatory program that maintains competence for normal ureteric budding, with defective normal induction and ectopic buds distinguished. The already asserted positive regulation of ureteric-bud formation has an actual is_a path to regulation of developmental process and supplies an informative replacement. This does not equate regulation with direct participation in every developmental process or infer all ARBA rule conditions have been experimentally checked.

Proposed replacements: positive regulation of ureteric bud formation

Summary: The traced experiment measures TCR-dependent induction of GATA3 rather than GATA3-dependent TCR signal propagation.

Reason: PMID:20696860 compares antigen/TCR and IL-4 stimulation of mouse CD4 cells and directly measures increased GATA3 translation downstream of TCR–PI3K–mTOR activity. Its inspected Methods and Results do not show GATA3 executing receptor-proximal or feedback signal propagation. The definition concerns the molecular signal series initiated by the T-cell receptor; assignment from regulation of GATA3 abundance overstates this source. Retain GATA3’s established role in the resulting transcriptional differentiation program and the literal ortholog-transfer context. This does not reject signaling solely because GATA3 is a transcription factor or infer universal absence of TCR-related feedback.

This does not reject signaling solely because GATA3 is a transcription factor or infer universal absence of TCR-related feedback.

Summary: The cartilage study is positive for GATA3, but the exact mammalian transfer remains unresolved.

Reason: The authentic PMID:29247144 abstract explicitly describes chick articular-cartilage experiments: ectopic GATA3 favors articular differentiation and inhibition favors transient cartilage. The current human annotation is transferred from mouse, and the original Methods and target construct sequences were not recovered to resolve that precise donor chain or mammalian experimental scope. Keep this context undecided rather than infer a wrong-gene or wrong-species curation error from the abstract. The positive cartilage evidence remains, but it is not represented as a directly inspected human or mouse assay.

Summary: GATA3 positively regulates Ang1-dependent PI3K–AKT signaling in endothelial cells.

Reason: PMID:19674970 directly measures Ang1-dependent AKT phosphorylation after GATA3 depletion and establishes GATA3-dependent Tie2 transcription. The signaling effect is consistent with transcriptional maintenance of the receptor and is selective relative to the tested VEGF response. Keep this supported regulatory context as non-core; do not assign PI3K or AKT enzymatic activity to GATA3.

Summary: GATA3 contributes to pharyngeal-region developmental patterning in the cardiac model.

Reason: The authentic PMID:18955134 abstract combines early Gata3 expression in branchial-arch mesenchyme/epithelium and outflow structures with Gata3-null aortic-arch and outflow malformations. The current GO definition includes the pharyngeal arches and their aortic-arch/cardiac-outflow contributions, so this supports the broad developmental context as a non-core ortholog inference. It does not establish every pharyngeal derivative or a direct human assay. Late LacZ signal is lineage history, and the complete original tissue panels remain uninspected.

It does not establish every pharyngeal derivative or a direct human assay. Late LacZ signal is lineage history, and the complete original tissue panels remain uninspected.

Summary: Uterine agenesis is a real phenotype, with a neighboring-duct mechanism rather than demonstrated uterine developmental work.

Reason: In the inspected original PMID:19112489, Gata3 is deleted in the nephric duct; female embryos show uterine agenesis and Müllerian-duct elongation arrest where ectopic ureteric buds occur. The tested Müllerian regulators remain expressed, and the authors explicitly propose physical obstruction by ectopic buds as a possible explanation. Mark direct involvement in uterus development as over-annotated from this source while preserving the positive phenotype and its developmental relevance. Obstruction is a proposed mechanism, not proven exclusivity, and this decision does not assert universal absence of GATA3 roles in uterine tissues.

Summary: The traced kidney evidence places GATA3 downstream of beta-catenin in a developmental transcriptional cascade.

Reason: The mouse donor for this canonical-Wnt term cites PMID:19112489. Inspected original Results and Methods show that beta-catenin loss reduces Gata3 and Ret, whereas Gata3 loss leaves beta-catenin/phospho-beta-catenin and canonical Axin2, Daple and Sp5 readouts unchanged. Mouse Gata3 supports a human RET regulatory-fragment reporter in mouse collecting-duct cells. These data establish a downstream Gata3-to-Ret transcriptional relay, not GATA3 execution of the canonical signal-transduction steps ending in beta-catenin-dependent target transcription. The pathway assignment overstates the traced function; the developmental cascade remains supported. This is not a duplicate-term objection, a claim that Wnt biology is poorly known, or a claim that GATA3 never influences Wnt responses in other contexts. Preserve the actual orthology source identifiers.

Summary: GATA3 can promote an epithelial transition in invasive breast-cancer cell models.

Reason: PMID:20189993 reports that ectopic GATA3 changes MDA-MB231 morphology and epithelial/mesenchymal markers, while GATA3 depletion in MCF7 cells produces complementary phenotypes. These data support the annotated transition in this experimental setting. Keep it as a non-core cellular context, not a claim that every normal GATA3-expressing cell undergoes this transition or that its expression always suppresses cancer.

Summary: GATA3 supports the formation of the ureteric bud from the nephric duct.

Reason: The donor trail cites PMID:16319112, whose accessible abstract establishes nephric-duct morphogenesis and Ret regulation but does not expose every budding assay. Independent inspected PMID:19112489 Results show that normal primary ureteric-bud formation usually fails after conditional Gata3 deletion. Ectopic buds contain residual Gata3-positive/Ret-positive cells from incomplete deletion; they do not show that deleted cells autonomously initiate a normal bud. This supports the conserved initial-bud developmental claim. Bud formation is kept distinct from subsequent branching morphogenesis and from an unqualified claim of positive branching regulation.

Summary: GATA3 expression is induced by interleukin4 in human CD4 cells.

Reason: Recovered original PMID:20554961 reports increased GATA3 RNA and protein in IL4-treated primary human CD4 cells, with IFN-alpha counter-regulation. This directly supports the expression-response term in the specified context. It does not assign IL4 receptor binding to GATA3 or make every observed signaling step a new molecular function.

Summary: Human endothelial GATA3 expression responds to tumor necrosis factor.

Reason: Original PMID:19674970 measures decreased GATA3 mRNA in HUVEC after TNF-alpha exposure and reduced Tie2 expression, which GATA3 overexpression can reverse. The GO definition includes stimulus-dependent gene-expression changes, so a response annotation is compatible with down-regulation. Preserve the IEP context as non-core without converting an expression response into direct TNF binding or receptor signaling activity.

Summary: GATA3 positively regulates normal ureteric-bud formation through the nephric-duct transcriptional program.

Reason: The actual mouse donor PMID:19112489 shows failure of normal primary bud formation after Gata3 deletion and reduced Ret expression. The ectopic buds retain Gata3 and Ret because deletion is incomplete, and the original cell-culture reporter supports Gata3 control of a RET regulatory element. Together these results support a positive role in normal initial-bud formation rather than a contradictory negative role inferred from counting ectopic buds. The term does not assert positive regulation of later ureteric branching. Retain this developmental function as non-core and preserve the literal transfer record.

Summary: GATA3 regulates nephric-duct shape and organization during urogenital development.

Reason: Inspected PMID:19112489 Results show a more sinuous duct, ectopic budding, later duct enlargement and altered epithelial differentiation after conditional mouse Gata3 deletion. The authentic PMID:16319112 abstract independently reports enhanced duct cellularity/proliferation and aberrant elongation following Gata3 inactivation. These provide positive evidence for nephric-duct morphogenesis, rather than relying only on human disease association. Retain the conserved developmental claim as non-core, without treating morphogenesis as proof of the narrower initial-formation step.

Summary: GATA3 supports nascent nephric-duct formation.

Reason: Original mouse experiments support nascent duct organization without requiring a failure of lineage specification. Keep this developmental function as non-core; see GATA3-external-evidence.md for the evidence and access limits.

Reason: Original mouse experiments support nascent duct organization without requiring a failure of lineage specification. Keep this developmental function as non-core; see GATA3-external-evidence.md for the evidence and access limits.

Summary: The nephron-tubule epithelial differentiation claim requires a more precise lineage and assay link.

Reason: The actual mouse donor cites PMID:19112489. Inspected Results show premature acquisition of collecting-duct identity by nephric-duct cells, measured by DBA and ZO1, and a separate reduction in Fgf8-positive nephron precursors in dysplastic kidneys. These support epithelial-state control and impaired nephron induction, but nephric/collecting-duct identity is not interchangeable with nephron-tubule epithelial differentiation. The official GO:0072182 definition and inspected children do not resolve that distinction. Retain the current source-specific assertion as undecided pending the precise lineage/assay link; this is not a claim that the developmental observations are false or that no indirect regulation occurs.

Retain the current source-specific assertion as undecided pending the precise lineage/assay link; this is not a claim that the developmental observations are false or that no indirect regulation occurs.

Summary: A GATA3-specific lymphocyte migration experiment is not established in the inspected source.

Reason: Recovered PMID:19805038 Results identify GATA3 occupancy at CCR5 and CCL27 and infer a migration-related transcriptional program. The main perturbation and chemokine induction experiments manipulate T-bet, not GATA3, and no direct GATA3 lymphocyte-migration assay was identified in the complete main text or captions. Supplementary experimental details have not been independently read. Keep the original IDA claim undecided rather than equate target-gene enrichment with measured migration or infer universal absence.

Summary: GATA3 contributes to developmental cochlear innervation.

Reason: Independent mouse experiments establish a role in cochlear wiring development, despite preserved gross organ shape. This supports a non-core cochlea-development annotation. The original rat expression evidence remains separately limited; no human perturbation is inferred. See GATA3-external-evidence.md for the experiment and access scope.

Summary: The broad anatomical-development ancestor is supported by narrower developmental annotations.

Reason: The current human record includes experimental kidney-development annotations, and official GO ancestry places kidney development within animal gross anatomical part developmental process. Thus breadth alone is not a reason to reject this developmental assertion. Retain it as non-core, with more specific lineage terms carrying the useful detail. ARBA00098139 currently returns 404; its unseen rule conditions are not claimed as verified or treated as proof that the original inference was wrong. This does not reverse the earlier evidence-based rejection of the specific ureteric-branching terms.

Summary: GATA3 activates miR573 transcription in human prostate-cancer models.

Reason: PMID:26451614 reports GATA3 expression constructs, promoter-length and dose-dependent reporter assays, miR573 measurements and anti-GATA3 ChIP. The experiments support the named miRNA transcriptional regulation and its EMT-related context. Retain all three original extension atoms as one conjunction, including the literal RNAcentral input/output identifiers; they are provenance from the curator and are not silently replaced by guessed precursor or mature sequences. This specific downstream regulatory output is non-core.

Summary: GATA3 reduces motility and invasion in the studied breast-cancer models.

Reason: The inspected PMID:20189993 Results describe reduced Matrigel invasion after GATA3 expression and increased motility after effective GATA3 depletion, alongside altered aggregation and CDH1 regulation. Keep this direct context-specific negative regulation of motility as non-core. The transcriptional mechanism is distinguished from a direct motor or cytoskeletal function.

Summary: GATA3 enables the anti-apoptotic effect of Ang1 in stressed human endothelial cells.

Reason: PMID:19674970 compares control and GATA3-depleted HUVEC under serum starvation with and without Ang1. Annexin-V assays show that Ang1 protects control cells but not depleted cells; the paper also reports TUNEL results in its supplement, whose images were not independently inspected here. The transcriptional Tie2 mechanism supports negative regulation of apoptosis in this context, not a general apoptosis-inhibitor molecular activity.

Summary: The cited HDR phenotype does not by itself resolve a role in thyroid-hormone generation.

Reason: PMID:19248180 explicitly describes hypoparathyroidism, which concerns parathyroid hormone and calcium homeostasis rather than thyroid hormones. The inherited rationale incorrectly treated that phenotype as sufficient evidence for this term. The complete original paper remains inaccessible after the publisher attempt, so any additional thyroid-specific assay cannot be adjudicated here. Keep the original IMP claim undecided; do not assert that GATA3 cannot regulate thyroid biology or invent a replacement from the clinical diagnosis.

Summary: Thyroid-hormone generation remains unverified in the cited GATA3 HDR study.

Reason: The authentic PMID:19723756 abstract establishes an HDR-associated mutation and transcription-factor defects, not thyroid-hormone generation. Hypoparathyroidism is not synonymous with impaired thyroid-hormone synthesis. The publisher PDF route did not provide the full paper, and no thyroid-specific assay was independently read. Preserve this source-specific IMP assertion as undecided rather than carry the inherited thyroid/parathyroid conflation or claim universal biological absence.

Summary: GATA3 supports NFAT1 occupancy at the human IL13 promoter.

Reason: The authentic PMID:20368097 abstract explicitly states that GATA3 siRNA inhibits NFAT1 binding to the IL13 promoter in activated Hut78 cells. That ChIP result supports positive regulation of transcription-regulatory-region DNA binding, which is distinct from assigning the NFAT1 binding activity to GATA3. Keep the promoter-complex effect as non-core; full original Methods and figures remain unavailable in this reading.

Summary: GATA3 shapes the transcriptional response of human keratinocytes to low-dose X radiation.

Reason: PMID:19735555 directly compares primary human keratinocytes with GATA3 knockdown versus control, sham irradiation versus1cGy exposure, transcript profiles and short- and long-term response assays. GATA3 depletion changes the transcriptional response and short-term sensitivity at the low dose, whereas the described long-term response is not uniformly altered. Keep this specific environmental-response regulation as non-core, without assigning DNA-repair chemistry or broad resistance to all radiation doses.

Summary: GATA3 acts in the nucleus as a chromatin-associated transcription factor.

Reason: The actual PTHR10071 target inherits the PTN001600628 nuclear-location assertion, with its own experimental donor evidence and no retained intervening loss. Human nuclear-extract, promoter ChIP and transcription-complex assays in PMID:17075044 and PMID:20484083 corroborate the nuclear site of action. The informative nucleus term is retained under the root-organelle policy rather than replaced by nucleoplasm.

Summary: GATA3 associates with chromatin at its regulatory target genes.

Reason: Human primary-cell ChIP and promoter occupancy experiments directly demonstrate chromatin association, corroborating the TFClass location assertion. Retain this core functional compartment without interpreting the broad chromatin label as enzymatic remodeling or proof of nucleosome binding by this particular source. The separate inherited nucleosome-related proposal is assessed from its own structural evidence.

Summary: GATA3 occupies chromatin at the NKX3.1 promoter in human T-cell lines.

Reason: The inspected original PMID:20855495 Methods and Results describe anti-GATA3 chromatin immunoprecipitation of the human NKX3.1 promoter in both TAL1-expressing and nonexpressing T-cell lines. This is positive chromatin association independent of whether the promoter is active. Retain the location without equating ChIP occupancy with a histone-binding enzyme or claiming purified nucleosome recognition from this experiment alone.

Summary: Nuclear localization is an established compartment of GATA3 transcriptional activity.

Reason: GATA3 occupies nuclear chromatin and controls transcription in human cells, independently supported by the inspected target-specific chromatin and protein-association experiments. The LIFEdb localization assertion is therefore biologically consistent. Its original screening construct and image were not independently recovered here; no natural-product-specific localization is inferred. Retain the informative root nuclear compartment alongside more precise nuclear locations.

Summary: GATA3 acts in the nucleus as a DNA-binding transcription regulator.

Reason: The combined ortholog, domain and UniProt subcellular-location mapping agrees with direct human nuclear staining and chromatin occupancy. Nucleus is an informative core site, not an uninformative parent requiring automatic deletion. Preserve the literal supporting identifiers and avoid claiming that GATA3 is exclusively nuclear under every condition.

Summary: GATA3 localizes to endothelial nuclei.

Reason: Original PMID:19674970 Methods and Results report GATA3 immunofluorescence in HUVEC with nuclear staining, together with nuclear-extract and chromatin-binding assays. The human nuclear-location claim is direct and concordant with its transcription-factor mechanism. Retain the informative nucleus term; no modern isoform specificity or figure-image inspection is claimed.

Summary: Wild-type and Thr272Ile GATA3 retain nuclear localization in the tested cells.

Reason: The PMID:19723756 abstract explicitly reports immunofluorescence and immunocytochemistry showing that the mutation does not affect GATA3 nuclear localization after construct transfection into COS7 cells. This supports the positive wild-type nuclear location and agrees with independently inspected human nuclear experiments. Retain nucleus as the informative core site of transcriptional action, without labeling the mutant as cytoplasmic or assigning the assay to an unverified natural isoform.

Summary: GATA3 is nuclear in normal mammary ductal epithelium and the evaluated breast specimens.

Reason: PMID:20189993 Results explicitly describe nuclear GATA3 staining in normal breast ductal epithelial cells, with tissue expression compared across tumor samples. This agrees with its promoter-associated transcriptional role. Retain nucleus; do not infer exclusive localization in all cells from the selected tissue observations or claim image inspection beyond the original text read.

Summary: The nuclear location is supported independently, while the cited embryo experiment retains an access limit.

Reason: The inspected PMID:22529382 cache contains its abstract and Discussion, not the target-specific Methods, Results or images; its emphasis on TEAD4 does not demonstrate that GATA3 was absent from the full experiment. Nuclear GATA3 is independently established by human chromatin and transcription-complex experiments. Accept the true nuclear-location claim on that combined evidence and defer to the experimental curator for this source-specific annotation, without inventing a GATA3 embryo panel, transferring TEAD4 localization behavior, or claiming that the original GATA3 assay was inspected.

Summary: GATA3 localizes to the nucleoplasm in the Human Protein Atlas record.

Reason: The actual target-specific Human Protein Atlas entry reports supported nucleoplasmic immunofluorescence localization for GATA3. This corroborates the literal HPA IDA annotation and agrees with its transcriptional role. The current database record was read, but the underlying fluorescence image and antibody-validation experiments were not independently inspected. This supports a nuclear compartment, not uniform expression or localization in every cell type or a particular natural product.

Summary: The electronically assigned nucleoplasmic location agrees with target-specific localization evidence.

Reason: The nucleoplasmic prediction is independently supported by the actual HPA GATA3 localization record and human nuclear chromatin experiments. Accept the location as part of the protein’s transcriptional mechanism. The complete current ARBA00026290 condition tree was not inspected, so this is a whole-claim biological assessment rather than an independent validation of every rule condition or a claim that rule inference itself is experimental.

Summary: Polyubiquitinated human GATA3 is represented in the nucleoplasm during USP21-mediated deubiquitination.

Reason: The original Reactome event contains input complex6783123, whose hasComponent set6783019 hasMember polyubiquitinated GATA3 entity6783009. The terminal protein is human UniProt:P23771, residues1–443, explicitly assigned nucleoplasm. This supports the location of the GATA3 substrate; USP21 performs deubiquitination. Model membership is not a GATA3 deubiquitinase assay. The checked evidence is the original curated human Reactome model and its typed entity chain; the event’s cited original papers were not independently read for this location audit. Nucleoplasmic localization is consistent with the independently established core DNA-binding transcription-factor role.

Summary: Human GATA3 is placed in the nucleoplasm in its expression model.

Reason: The actual output of Reactome event6793975 is entity996768, human UniProt:P23771 residues1–443, with nucleoplasm as its compartment. The STAT6-dependent expression model places the resulting transcription factor in its functional nuclear compartment. It does not attribute STAT6 activity to GATA3 or itself measure a specific GATA3 isoform. The checked evidence is the original curated human Reactome model and its typed entity chain; the event’s cited original papers were not independently read for this location audit. Nucleoplasmic localization is consistent with the independently established core DNA-binding transcription-factor role.

Summary: The GATA3 member of the core TAL1 regulatory complex is nucleoplasmic.

Reason: The actual event input8956524 contains DefinedSet8956530, which explicitly includes GATA3 entity996768. Its reference entity is human UniProt:P23771 and its compartment is nucleoplasm. GATA1/GATA2/GATA3 are alternative members of the model set; this location decision does not assert that all three coexist in one complex or that every model alternative was assayed in every cited paper. The checked evidence is the original curated human Reactome model and its typed entity chain; the event’s cited original papers were not independently read for this location audit. Nucleoplasmic localization is consistent with the independently established core DNA-binding transcription-factor role.

Summary: GATA3-containing TAL1 assemblies at the MYB enhancer are modeled in the nucleoplasm.

Reason: The actual output8956585 contains set8956602. Both its RUNX1–CBFB–GATA3 member8956591 and its additional-MYB member8956603 lead through GATA3 core complex8956589 to human P23771 entity996768 in nucleoplasm. These explicit alternative paths support location without converting every modeled assembly into a separately verified binding experiment. The checked evidence is the original curated human Reactome model and its typed entity chain; the event’s cited original papers were not independently read for this location audit. Nucleoplasmic localization is consistent with the independently established core DNA-binding transcription-factor role.

Summary: GATA3 acts at the CCND1 promoter in the nucleoplasm.

Reason: The actual promoter-binding event directly lists GATA3 entity996768 as input, identified as human UniProt:P23771 and assigned nucleoplasm. This is a relevant location for GATA3 transcriptional regulatory activity. The model pairs FOXA1 and GATA3 at chromatin; FOXA1 winged-helix structural descriptions in the summation are not GATA3 domain evidence. The checked evidence is the original curated human Reactome model and its typed entity chain; the event’s cited original papers were not independently read for this location audit. Nucleoplasmic localization is consistent with the independently established core DNA-binding transcription-factor role.

Summary: GATA3 remains nucleoplasmic in the CCND1 regulatory assembly during AP1 recruitment.

Reason: The actual event input9009057 is the CCND1 chromatin–FOXA1–GATA3 assembly and directly contains human P23771 entity996768 in nucleoplasm. The location is supported by the pre-existing GATA3 component. This does not make GATA3 an AP1 subunit or establish one universal order of regulator recruitment. The checked evidence is the original curated human Reactome model and its typed entity chain; the event’s cited original papers were not independently read for this location audit. Nucleoplasmic localization is consistent with the independently established core DNA-binding transcription-factor role.

Summary: GATA3 is nucleoplasmic in the TFF1 regulatory assembly used for CARM1 recruitment.

Reason: The actual input9009538 contains9009528, which contains9009531, which contains TFF1–FOXA1–GATA3 complex9023820 and human P23771 entity996768. The explicit hasComponent chain places GATA3 in nucleoplasm. The event models recruitment of CARM1 to this assembly; it does not assign CARM1 histone methyltransferase activity to GATA3. The checked evidence is the original curated human Reactome model and its typed entity chain; the event’s cited original papers were not independently read for this location audit. Nucleoplasmic localization is consistent with the independently established core DNA-binding transcription-factor role.

Summary: The TFF1-associated GATA3 component is nucleoplasmic during TBP and TFIIA recruitment.

Reason: The actual event input9009528 contains9009531, then TFF1–FOXA1–GATA3 complex9023820 and human P23771 entity996768. This chain supports nucleoplasmic GATA3 in the transcriptional assembly. The event title concerns TBP/TFIIA recruitment and does not imply that GATA3 itself supplies general transcription-factor or TATA-binding activity. The checked evidence is the original curated human Reactome model and its typed entity chain; the event’s cited original papers were not independently read for this location audit. Nucleoplasmic localization is consistent with the independently established core DNA-binding transcription-factor role.

Summary: GATA3 is nucleoplasmic in the TFF1 complex to which DDX5 is recruited.

Reason: The recovered original Reactome model has input9009531, whose hasComponent complex9023820 contains GATA3 entity996768, identified as human UniProt:P23771 in nucleoplasm. The positive model supports the location even though the normal repository cache was initially absent. DDX5 is the recruited helicase; no helicase activity is inferred for GATA3. The checked evidence is the original curated human Reactome model and its typed entity chain; the event’s cited original papers were not independently read for this location audit. Nucleoplasmic localization is consistent with the independently established core DNA-binding transcription-factor role.

Summary: The GATA3 component of the TFF1 promoter assembly is nucleoplasmic during ESR1 recruitment.

Reason: The original event input9023820 directly includes GATA3 entity996768, with human P23771 identity and nucleoplasmic compartment. The model supports GATA3 in the pre-existing promoter regulatory complex. ESR1 hormone-receptor activity and the detailed timing of repeated cofactor recruitment are not attributed to GATA3 by this location decision. The checked evidence is the original curated human Reactome model and its typed entity chain; the event’s cited original papers were not independently read for this location audit. Nucleoplasmic localization is consistent with the independently established core DNA-binding transcription-factor role.

Summary: GATA3 occupies the nucleoplasmic compartment in TFF gene regulation.

Reason: The original event directly lists GATA3 entity996768 as input and assigns this human P23771 protein to nucleoplasm. GATA3 and FOXA1 are modeled as promoter-associated regulators. The extracellular functions of the TFF gene products do not describe the location of their GATA3 transcription factor. The checked evidence is the original curated human Reactome model and its typed entity chain; the event’s cited original papers were not independently read for this location audit. Nucleoplasmic localization is consistent with the independently established core DNA-binding transcription-factor role.

Summary: GATA3 is nucleoplasmic in the TFF3 promoter assembly used for ESR1 and EP300 recruitment.

Reason: The actual event input9018480 is the TFF3–FOXA1–GATA3 assembly and directly contains GATA3 entity996768, human P23771 in nucleoplasm. This supports core nuclear location. Recruitment of ESR1/EP300 does not itself make GATA3 a histone acetyltransferase or demonstrate an additional GATA3-mediated looping activity. The checked evidence is the original curated human Reactome model and its typed entity chain; the event’s cited original papers were not independently read for this location audit. Nucleoplasmic localization is consistent with the independently established core DNA-binding transcription-factor role.

Summary: GATA3 is nucleoplasmic in the modeled TFF1 assemblies that recruit histone acetyltransferases.

Reason: The actual input DefinedSet9023865 has CARM1-containing member9009534 and PRMT1-containing member9023863. Each leads through9009538,9009528,9009531 and TFF1–FOXA1–GATA3 complex9023820 to human P23771 entity996768 in nucleoplasm. Alternative membership supports location without claiming simultaneous occupancy by every methyltransferase/acetyltransferase or assigning their chemistry to GATA3. The checked evidence is the original curated human Reactome model and its typed entity chain; the event’s cited original papers were not independently read for this location audit. Nucleoplasmic localization is consistent with the independently established core DNA-binding transcription-factor role.

Summary: GATA3 remains nucleoplasmic in the TFF1 assembly used for PRMT1 recruitment.

Reason: The original event input9009538 contains9009528,9009531 and TFF1–FOXA1–GATA3 complex9023820, whose component996768 is human P23771 in nucleoplasm. The explicit component path supports GATA3 location. PRMT1-mediated histone methylation is a different component’s activity, not a catalytic function of GATA3. The checked evidence is the original curated human Reactome model and its typed entity chain; the event’s cited original papers were not independently read for this location audit. Nucleoplasmic localization is consistent with the independently established core DNA-binding transcription-factor role.

Summary: The ESR1–PGR hormone-receptor model explicitly includes nucleoplasmic GATA3.

Reason: The actual Reactome R-HSA-9038163 event includes the GATA3 entity with reference accession P23771 and nucleoplasm compartment among the input proteins recruited with the ESR1–PGR hormone-receptor complex and coactivators. This verifies the target and location rather than relying on the event title. Accept the compartment claim; the model does not by itself establish every represented physical interaction as a purified binary assay, an original-paper experiment independently read here, or a hormone-receptor activity of GATA3.

Summary: GATA3 is an explicit member of the nucleoplasmic GATA set in the ZFPM-binding model.

Reason: The actual Reactome R-HSA-996755 input set has a literal hasMember link to GATA3, reference accession P23771, in the nucleoplasm. The localization is consequently target-specific within the curated model and agrees with the protein’s nuclear transcriptional function. The set membership is not evidence that every GATA paralog was tested identically, and this review does not claim to have independently inspected all original ZFPM binding assays.

Summary: Human GATA3 zinc fingers directly recognize target sequences in nucleosomal DNA.

Reason: This refines the inherited chromatin-binding proposal to its directly demonstrated nucleosome-binding mechanism, rather than adding both parent and child. PMID:32811816 assays a purified human P23771-2-derived fragment 261–371 against reconstituted nucleosomes, including target-motif disruption and a cryo-EM complex. The source distinguishes nucleosome binding from productive chromatin opening; it does not assign ATP-dependent remodeling chemistry to GATA3 or establish natural-product-exclusive activity. GO:0031491 is an actual is_a descendant of GO:0003682, and neither binding term occurs among the 197 current original contexts. The existing cis-regulatory DNA-binding term does not entail this nucleosomal substrate context.
