FOXP2 source and assay guide

All 72 original QuickGO contexts and 72 exported rows were reconciled with the genuine 70-row seed. Two pairs differ by nuclear scope and are retained as 72 distinct review contexts. All eleven original extension atoms and partner isoform identifiers remain intact. The source evidence preserves the complete originals and actual raw-to-native-to-reviewed mapping.

FOXP2 is a nuclear transcription factor with direct human regulatory-DNA binding and repression evidence. Target-dependent activation, model-dependent neuronal development and cooperative mouse muscle-development findings remain distinct. Positive pair assays are interpreted within their recorded host, construct and detection method. No new annotation or publication quotation is proposed.

The official record declares nine products and supports eight sequence reconstructions. O15409-3 is explicitly Not described. Historical clone names, the 714-aa BC143867 construct, the 503–584 structural fragment and an annotated 93–715 interaction region are not assigned to natural products without exact construct evidence.

The actual PTHR45796 human target is PTN002483647/AN150, matching the 715-aa displayed sequence. All seven incoming IBA objects join literal IBDs on its path, across four distinct ancestral nodes. The original donor groupings remain exact; human self-donor evidence is legitimate experimental grounding. Current rat vocalization ISO/IBA records are distinguished from an original direct rat experiment.

Compartment and ontology scope

Official HPA ICC/IF metadata identify nucleoplasm as the enhanced main location, with human HEK293, Rh30 and U2OS assay metadata. The existing HPA nucleoplasm annotation is retained; the core synthesis uses the broader nucleus location supported by the combined sources. Image pixels and antibody experiments were not independently reanalyzed. Other image-level location metadata are not promoted to NEW annotations.

All sixteen TOO_GENERAL decisions have a retained asserted narrower term connected by an official is_a path. GO:0010467 gene expression and the organ/system developmental contexts remain non-core; part_of containment is not treated as an is_a redundancy argument. FOXP1/FOXP4 class refinements preserve association-versus-direct-contact limits. CTBP/TLE refinements identify the partner class without claiming a functional repression assay for each screened pair.

Source follow-up

All 27 normal sources are present: 18 existing files were reused byte-for-byte and nine absent publication caches were genuinely acquired. All ten shared FOXP1 source files, including the three PTHR45796 files, were reused from accepted main without rewriting. The eight-row normal PAINT slice independently matches all seven incoming assertions at their proven target-path nodes. Normal-cache availability and actual selected-original access are recorded separately; selected reading does not imply full-paper, image or supplement coverage. Manual primary research supplied the evidence record under the existing provider credential hold; no provider run was made. Execution outcomes are recorded in the notes.
