The research report should be a detailed narrative explaining the function, biological processes, and localization of the gene product. Citations should be given for all claims.
You should prioritize authoritative reviews and primary scientific literature when conducting research. You can supplement
this with annotations you find in gene/protein databases, but these can be outdated or inaccurate.
We are specifically interested in the primary function of the gene - for enzymes, what reaction is catalyzed, and what is the substrate specificity? For transporters, what is the substrate? For structural proteins or adapters, what is the broader structural role? For signaling molecules, what is the role in the pathway.
We are interested in where in or outside the cell the gene product carries out its function.
We are also interested in the signaling or biochemical pathways in which the gene functions. We are less interested in broad pleiotropic effects, except where these elucidate the precise role.
Include evidence where possible. We are interested in both experimental evidence as well as inference from structure, evolution, or bioinformatic analysis. Precise studies should be prioritized over high-throughput, where available.
This report provides a comprehensive functional annotation of the gene esrp1 (UniProt accession: A0A4W3GVU1) from Callorhinchus milii (ghost shark). Important note: No species-specific literature exists for ESRP1 in ghost shark. However, the protein belongs to the highly conserved ESRP family with well-characterized orthologs across vertebrates, enabling robust functional inference based on evolutionary conservation and extensive mammalian research (derham2023thediscoveryfunction pages 1-3, warzecha2009esrp1andesrp2 pages 3-4). This annotation draws primarily from studies in mammalian model systems where ESRP1 function has been extensively characterized.
ESRP1 is a member of the epithelial splicing regulatory protein (ESRP) family and belongs to the broader heterogeneous nuclear ribonucleoprotein (hnRNP) family of RNA-binding proteins (derham2023thediscoveryfunction pages 1-3, derham2023thediscoveryfunction pages 3-4). The ESRP family shows remarkable evolutionary conservation across metazoan species, with orthologs identified in:
This broad conservation across vertebrates and invertebrates indicates an essential and ancient role in epithelial cell biology, strongly supporting that the ghost shark ortholog performs analogous functions to its mammalian counterparts.
The ghost shark ESRP1 protein contains the characteristic domain architecture of the ESRP family. Based on mammalian ESRP1 structure and the UniProt annotation indicating RRM domains:

Table: This table summarizes the known and inferred structural organization of ESRP1, emphasizing conserved RNA-binding domains, paralog-specific regions, and localization features. It is useful for annotating the ghost shark ESRP1 ortholog because direct species-specific literature is lacking but domain-level function is strongly conserved.
Key Structural Features:
Three RNA Recognition Motifs (RRMs): These domains exhibit high sequence conservation across species - RRM1 (89% identity), RRM2 (68% identity), and RRM3 (76% identity relative to mouse Esrp1) (derham2023thediscoveryfunction pages 1-3, derham2023thediscoveryfunction pages 3-4). RRM2 and RRM3 are particularly critical for RNA binding and splicing regulation.
RNA-Binding Specificity: The X-ray crystal structure of the ESRP1 qRRM2 domain reveals it binds to GGU motifs with guanines embedded in clamp-like aromatic pockets, explaining the protein's preference for UGG-rich and GGU-rich RNA sequences (liu2024esrp1controlsbiogenesis pages 1-2, derham2023thediscoveryfunction pages 3-4).
Additional Domains: ESRP1 contains an N-terminal DNAQ-like exonuclease domain and a C-terminal DAZAP2-like domain, though their specific functions remain incompletely characterized (derham2023thediscoveryfunction pages 3-4).
Nuclear Localization: ESRP1 contains a putative nuclear localization sequence (pNLS) and exists as both nuclear and cytoplasmic isoforms generated by alternative splicing at exon 12 (derham2023thediscoveryfunction pages 3-4, derham2023thediscoveryfunction pages 4-6).
ESRP1 functions as a sequence-specific RNA-binding protein that regulates alternative splicing of pre-mRNA transcripts. Unlike catalytic splicing enzymes, ESRP1 does not directly catalyze splicing reactions but instead modulates spliceosome recruitment and activity through binding to specific cis-regulatory elements (warzecha2009esrp1andesrp2 pages 1-2, peart2022theglobalproteinrna pages 1-2).
Substrate Recognition:
- Consensus binding motif: UGG-rich and GGU-rich RNA sequences (derham2023thediscoveryfunction pages 3-4, derham2023thediscoveryfunction pages 4-6)
- Binds to intronic splicing enhancer/silencer elements (ISE/ISS) and exonic regulatory regions (derham2023thediscoveryfunction pages 1-3, warzecha2010anesrp‐regulatedsplicing pages 1-2)
ESRP1 employs a sophisticated position-dependent mechanism to control exon inclusion or exclusion (derham2023thediscoveryfunction pages 3-4, derham2023thediscoveryfunction pages 4-6):
This positional code allows ESRP1 to exert context-dependent regulatory control across hundreds of target genes.
ESRP1 regulates a comprehensive epithelial-specific splicing program affecting hundreds of genes. Well-characterized targets include:
| Target Gene | Alternative Splicing Event Regulated | Functional Consequence of ESRP1 Regulation | Biological Context | Citation |
|---|---|---|---|---|
| FGFR2 | Controls mutually exclusive choice of exon IIIb (epithelial) versus exon IIIc (mesenchymal); ESRP1 promotes IIIb and represses IIIc by binding intronic regulatory elements including ISE/ISS-3 | Switches receptor ligand specificity: FGFR2-IIIb binds epithelial ligands such as FGF1, FGF3, FGF7, FGF10, FGF22, whereas FGFR2-IIIc recognizes FGF1, FGF2, FGF4, FGF6, FGF9, FGF16, FGF20; thereby helps maintain epithelial signaling identity and epithelial–mesenchymal state | Canonical ESRP1 target; epithelial cell identity, EMT/MET regulation, developmental epithelial–mesenchymal signaling crosstalk | (warzecha2009esrp1andesrp2 pages 1-2, derham2023thediscoveryfunction pages 1-3, derham2023thediscoveryfunction pages 3-4, horiguchi2012tgfβdrivesepithelialmesenchymal pages 1-2) |
| CD44 | Promotes inclusion of variable exons (CD44v isoforms) and prevents switch to CD44s during EMT by binding intronic regions flanking variable exons | Maintains epithelial-associated CD44 isoform profile; blocking ESRP1 expression favors CD44s, which is linked to EMT progression, increased motility, and mesenchymal conversion | EMT regulation and cancer-related epithelial plasticity | (reinke2012snailrepressesthe pages 1-2, warzecha2009esrp1andesrp2 pages 1-2, derham2023thediscoveryfunction pages 4-6) |
| CTNND1 (p120-catenin) | ESRP1 regulates alternative splicing of CTNND1 isoforms; exact exon details not specified in retrieved contexts, but CTNND1 is a validated direct ESRP program target | Supports epithelial cell functions related to adherens junctions and cell–cell adhesion; loss of ESRP activity shifts CTNND1 isoform usage and contributes to mesenchymal phenotypes; ESRP1 also has splicing-independent effects on CTNND1 protein abundance | Epithelial junction organization and EMT-associated remodeling | (warzecha2009esrp1andesrp2 pages 1-2, peart2022theglobalproteinrna pages 1-2, derham2023thediscoveryfunction pages 4-6, horiguchi2012tgfβdrivesepithelialmesenchymal pages 1-2) |
| ENAH (hMena) | ESRP1 regulates ENAH/hMena alternative splicing; precise exon numbers not specified in retrieved contexts, but ENAH is a recurrent ESRP-regulated epithelial target | Promotes epithelial isoforms associated with reduced invasive/migratory behavior; ESRP loss shifts toward mesenchymal splicing patterns that favor altered actin dynamics and motility | Cytoskeletal organization, epithelial morphology, EMT | (warzecha2009esrp1andesrp2 pages 1-2, derham2023thediscoveryfunction pages 3-4, derham2023thediscoveryfunction pages 4-6) |
| DOCK1 / circDOCK1(2–27) | ESRP1 promotes back-splicing/biogenesis of circDOCK1(2–27) from exons 2–27 by binding a GGU-containing repeat region in intron 1 and delaying canonical splicing | Represses cell motility in epithelial cells both by diverting transcripts away from linear DOCK1 mRNA production and via direct inhibitory effects of the circRNA on migration | Recent noncanonical ESRP1 function in circRNA biogenesis during EMT-related cell-state regulation | (liu2024esrp1controlsbiogenesis pages 1-2) |
| Multiple ESRP program genes involved in adhesion/polarity/cytoskeleton | ESRP1 directly binds introns and exons to regulate inclusion or skipping in a position-dependent manner: binding 75–250 nt downstream tends to promote exon inclusion, while binding within the exon or proximal upstream intron tends to promote exon exclusion | Coordinates an epithelial splicing program enriched for genes controlling cell–cell adhesion, polarity, tight junctions, exocyst/cytoskeletal functions, and migration | Global epithelial post-transcriptional program; maintenance of epithelial phenotype and suppression of EMT | (peart2022theglobalproteinrna pages 1-2, derham2023thediscoveryfunction pages 3-4, warzecha2010anesrp‐regulatedsplicing pages 1-2) |
| Genes in FGFR/epithelial developmental pathways | Broad ESRP-dependent epithelial splicing program affecting 134 genes in early microarray studies and 281 cassette exons in later RNA-seq/overexpression studies | Produces functionally coherent epithelial isoform networks required for tissue morphogenesis, barrier formation, and epithelial specialization | Mammalian development, epidermal homeostasis, craniofacial and limb development | (derham2023thediscoveryfunction pages 4-6, bebee2015thesplicingregulators pages 1-2, warzecha2010anesrp‐regulatedsplicing pages 1-2) |
Table: This table summarizes well-characterized ESRP1 RNA targets and the functional consequences of their splicing regulation. It is useful for annotating the ghost shark ESRP1 ortholog because it links conserved RNA-binding/splicing activity to concrete epithelial biological outcomes.
Canonical Example - FGFR2 Regulation:
ESRP1's best-characterized function is regulation of fibroblast growth factor receptor 2 (FGFR2) alternative splicing (warzecha2009esrp1andesrp2 pages 1-2, derham2023thediscoveryfunction pages 1-3). ESRP1 promotes inclusion of exon IIIb (epithelial isoform) while repressing exon IIIc (mesenchymal isoform) by binding to the ISE/ISS-3 regulatory element in intron 8 (warzecha2009esrp1andesrp2 pages 1-2, warzecha2009esrp1andesrp2 pages 3-4). This isoform switch is functionally critical because:
This differential ligand specificity establishes distinct epithelial versus mesenchymal FGF signaling programs (derham2023thediscoveryfunction pages 1-3, horiguchi2012tgfβdrivesepithelialmesenchymal pages 1-2).
High-throughput studies have identified:
- 134 genes with ESRP-regulated alternative splicing in early microarray studies (derham2023thediscoveryfunction pages 4-6)
- 281 cassette exon events regulated by ESRP1 in RNA-seq analyses (warzecha2010anesrp‐regulatedsplicing pages 1-2)
- Enrichment for genes involved in cell-cell adhesion, polarity, tight junctions, cytoskeletal organization, and cell migration (peart2022theglobalproteinrna pages 1-2, warzecha2010anesrp‐regulatedsplicing pages 1-2)
Recent evidence indicates ESRP1 functions extend beyond canonical splicing:
Circular RNA biogenesis: ESRP1 promotes back-splicing to generate circDOCK1(2-27) by binding GGU-repeat regions in DOCK1 intron 1 and detaining splicing (liu2024esrp1controlsbiogenesis pages 1-2)
Post-transcriptional regulation: ESRP1 binds extensively to 3' and 5' UTRs, suggesting roles in mRNA stability, translation, and alternative polyadenylation (peart2022theglobalproteinrna pages 1-2, derham2023thediscoveryfunction pages 3-4)
Protein abundance control: Cytoplasmic ESRP1 regulates CTNND1 protein levels through splicing-independent mechanisms (peart2022theglobalproteinrna pages 1-2)
ESRP1 exhibits dual subcellular localization with functionally distinct roles in different compartments (derham2023thediscoveryfunction pages 3-4, derham2023thediscoveryfunction pages 4-6):
This dual localization strategy enables ESRP1 to orchestrate both nuclear (splicing) and cytoplasmic (post-transcriptional) layers of gene regulation, expanding its regulatory repertoire beyond canonical splicing control.
ESRP1 serves as a master regulator of epithelial cell-type-specific gene expression programs (warzecha2009esrp1andesrp2 pages 1-2, bebee2015thesplicingregulators pages 1-2). It coordinates alternative splicing of genes essential for:
In mouse epidermis, ESRP deletion disrupts the epithelial splicing program required for establishing a proper skin barrier, a fundamental epithelial cell function (bebee2015thesplicingregulators pages 1-2).
ESRP1 plays a central inhibitory role in EMT, a developmental program where epithelial cells lose polarity and acquire mesenchymal characteristics (warzecha2010anesrp‐regulatedsplicing pages 1-2, derham2023thediscoveryfunction pages 4-6, horiguchi2012tgfβdrivesepithelialmesenchymal pages 1-2):
During EMT:
- ESRP1 expression is dramatically downregulated
- This downregulation is required for the epithelial-to-mesenchymal splicing switch
- Loss of ESRP1 allows mesenchymal-specific splicing patterns to predominate
- The splicing switch affects hundreds of genes, facilitating morphological and functional transformation
Transcriptional Regulation of ESRP1:
- Snail (SNAI1) directly represses ESRP1 transcription by binding E-boxes in the ESRP1 promoter (reinke2012snailrepressesthe pages 1-2)
- ZEB1/SIP1 family proteins (δEF1) repress ESRP2 transcription during TGF-β-induced EMT, with similar effects on ESRP1 (horiguchi2012tgfβdrivesepithelialmesenchymal pages 1-2)
- This transcriptional repression is required for EMT to proceed - ectopic ESRP1 expression inhibits Snail-induced EMT (reinke2012snailrepressesthe pages 1-2)
ESRP1 is essential for mammalian development, with loss-of-function causing severe developmental defects (bebee2015thesplicingregulators pages 1-2, derham2023thediscoveryfunction pages 4-6):
Human ESRP1 loss-of-function mutations cause sensorineural hearing loss linked to defective cochlear development and auditory hair cell differentiation (derham2023thediscoveryfunction pages 4-6)
Limb Development:
Regulates FGFR2 isoform expression critical for epithelial-mesenchymal signaling in the apical ectodermal ridge (derham2023thediscoveryfunction pages 4-6)
Organ Morphogenesis:
ESRP1 functions as a critical node linking alternative splicing to FGF signaling pathway regulation (derham2023thediscoveryfunction pages 1-3, horiguchi2012tgfβdrivesepithelialmesenchymal pages 1-2):
ESRP1 operates within complex regulatory networks involving other splicing factors (derham2023thediscoveryfunction pages 3-4, derham2023thediscoveryfunction pages 4-6):
Cooperative Regulators:
- RBFOX2: Co-regulates many targets; relationship can be cooperative or antagonistic depending on context
- RBM47: Promotes epithelial splicing patterns
Antagonistic Regulators:
- hnRNPM: Promotes mesenchymal splicing patterns; antagonizes ESRP1 activity during EMT (derham2023thediscoveryfunction pages 4-6)
- QKI: Promotes mesenchymal splicing program
This network architecture creates a finely tuned splicing regulatory system that responds to developmental and environmental cues to control epithelial-mesenchymal plasticity.
Given the absence of species-specific literature for ghost shark ESRP1, functional annotation must rely on evolutionary inference. The high degree of conservation observed for:
strongly supports that the ghost shark ESRP1 ortholog performs analogous functions to mammalian ESRP1, including:
The Callorhinchus milii esrp1 gene likely regulates alternative splicing of conserved epithelial genes such as FGFR2, CD44, and cytoskeletal/adhesion proteins, contributing to epithelial tissue specification and maintenance in this basal vertebrate lineage.
ESRP1 is an evolutionarily conserved, epithelial-specific RNA-binding protein that serves as a master regulator of alternative splicing. Through sequence-specific binding to UGG/GGU-rich motifs via its RRM domains, ESRP1 orchestrates a comprehensive splicing program affecting hundreds of genes involved in epithelial cell identity, cell adhesion, polarity, and cytoskeletal organization. The protein functions primarily in the nucleus to regulate pre-mRNA splicing in a position-dependent manner, but also has cytoplasmic roles in translation and mRNA stability. ESRP1 is essential for mammalian development, particularly craniofacial and limb formation, and plays a central inhibitory role in epithelial-mesenchymal transition by maintaining epithelial-specific splicing patterns. Its regulation of FGFR2 isoform switching exemplifies how alternative splicing integrates with growth factor signaling to establish cell-type-specific properties. While no ghost shark-specific studies exist, the remarkable evolutionary conservation of ESRP1 structure and function across vertebrates strongly supports analogous roles in Callorhinchus milii epithelial tissues.
