  • Function

    RNA-binding protein that plays a role in the regulation of alternative splicing and influences mRNA splice site selection and exon inclusion. May play a role as a negative regulator of cell growth. Inhibits cell proliferation. Involved in splice site selection of vascular endothelial growth factor. Induces an increased concentration-dependent incorporation of exon in CD44 pre-mRNA by direct binding to purine-rich exonic enhancer. RNA-binding abilities are down-regulated by tyrosine kinase PTK6. Involved in post-transcriptional regulation of HIV-1 gene expression.
  • 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.
  • Sequence similarities

    Belongs to the KHDRBS family.
    Contains 1 KH domain.
  • Domain

    The proline-rich site binds the SH3 domain of the p85 subunit of PI3-kinase.
  • Post-translational

    Phosphorylated on tyrosine residues. Isoform 1 C-terminal region is tyrosine-rich, but isoform 2 lacking this C-terminal region is also tyrosine-phosphorylated.
  • Cellular localization

    Nucleus. Localized in a compartment adjacent to the nucleolus, but distinct from the peri-nucleolar one.
