  • Function
    Component of the CRD-mediated complex that promotes MYC mRNA stabilization. Binds to pre-mRNA. Has high affinity for scaffold-attached region (SAR) DNA. Binds to double- and single-stranded DNA and RNA.
  • Sequence similarities
    Contains 1 B30.2/SPRY domain.
    Contains 1 SAP domain.
  • Post-translational
    Extensively phosphorylated.
    Arg-733 and Arg-739 are dimethylated, probably to asymmetric dimethylarginine.
  • Cellular localization
    Nucleus. Cytoplasm. Cell surface. Localized in cytoplasmic mRNP granules containing untranslated mRNAs. Component of ribonucleosomes. Also found associated with the cell surface.
