Summary
KHDRBS3 (KH RNA binding domain containing, signal transduction associated 3, HGNC:18117) is a protein-coding gene on chromosome 8q24.23, encoding KH domain-containing, RNA-binding, signal transduction-associated protein 3 (O75525). RNA-binding protein that plays a role in the regulation of alternative splicing and influences mRNA splice site selection and exon inclusion.
Enables RNA binding activity; identical protein binding activity; and protein domain specific binding activity. Predicted to be involved in regulation of alternative mRNA splicing, via spliceosome and spermatogenesis. Located in nucleoplasm. Part of protein-containing complex.

Function. RNA-binding protein that plays a role in the regulation of alternative splicing and influences mRNA splice site selection and exon inclusion. Binds preferentially to the 5’-[AU]UAAA-3’ motif in vitro. Binds optimally to RNA containing 5’-[AU]UAA-3’ as a bipartite motif spaced by more than 15 nucleotides. Binds poly(A). RNA-binding abilities are down-regulated by tyrosine kinase PTK6. Involved in splice site selection of vascular endothelial growth factor. In vitro regulates CD44 alternative splicing by direct binding to purine-rich exonic enhancer. Can regulate alternative splicing of neurexins NRXN1-3 in the laminin G-like domain 6 containing the evolutionary conserved neurexin alternative spliced segment 4 (AS4) involved in neurexin selective targeting to postsynaptic partners such as neuroligins and LRRTM family members. Targeted, cell-type specific splicing regulation of NRXN1 at AS4 is involved in neuronal glutamatergic synapse function and plasticity. May regulate expression of KHDRBS2/SLIM-1 in defined brain neuron populations by modifying its alternative splicing. Can bind FABP9 mRNA. May play a role as a negative regulator of cell growth. Inhibits cell proliferation. (Microbial infection) Involved in post-transcriptional regulation of HIV-1 gene expression.
Subunit / interactions. Self-associates to form homooligomers; dimerization increases RNA affinity. Interacts with KHDRBS2/SLM-1. Interacts with KHDRBS1/SAM68; heterooligomer formation of KHDRBS family proteins may modulate RNA substrate specificity. Interacts with the splicing regulatory proteins SFRS9, SAFB and YTHDC1. Interacts with HNRPL. Interacts with RBMX, RBMY1A1, p85 subunit of PI3-kinase, SERPINB5. Interacts with SIAH1 which promotes targeting for degradation.
Subcellular location. Nucleus.
Tissue specificity. Ubiquitous with higher expression in testis, skeletal muscle and brain. Expressed in the kidney only in podocytes, the glomerular epithelial cells of the kidney. Strongly expressed after meiosis.
Post-translational modifications. Phosphorylated on tyrosine residues. Isoform 1 C-terminal region is tyrosine-rich, but isoform 2 lacking this C-terminal region is also tyrosine-phosphorylated.
Domain organisation. The proline-rich site binds the SH3 domain of the p85 subunit of PI3-kinase.
Induction. Induced in proteinuric diseases. Down-regulated in immortalized fibroblasts isolated after a proliferative crisis accompanied with massive cell death.
Similarity. Belongs to the KHDRBS family.

Enriched among interaction partners
Reactome pathways and GO biological processes over-represented among this gene’s 97 IntAct physical interaction partners (hypergeometric vs the genome-wide background, BH-FDR, gene-set size 15–500, ranked by fold). A functional readout of the neighbourhood — distinct from this gene’s own memberships above, and biased toward well-studied / hub proteins, so read it as themes rather than proof.
