a nuclear RNA-binding protein. May be involved in slicing and mRNA transport. Associates with src in mitosis. Binds to RNA via a heteronuclear ribonucleoprotein K homology domain. Exerts functionally separable effects on cell proliferation and survival, dependent on its ability to bind specifically to RNA. Note: This description may include information from UniProtKB.
Molecular Function: DNA binding; identical protein binding; poly(A) binding; poly(U) binding; protein binding; RNA binding; SH3/SH2 adaptor activity
Biological Process: cell cycle arrest; cell proliferation; cell surface receptor linked signal transduction; G2/M transition of mitotic cell cycle; negative regulation of transcription, DNA-dependent; positive regulation of RNA export from nucleus; positive regulation of translational initiation; regulation of protein stability; regulation of RNA export from nucleus; signal transduction
