KH domain-containing, RNA-binding, signal transduction-associated protein 2 (Khdrbs2)

RNA-binding protein which plays a role in the regulation of alternative splicing and influences mRNA splice site selection and exon addition (By similarity). Binds both poly(A) and poly(U) homopolymers.

Phosphorylation by PTK6 inhibits its RNA-binding ability. Induces an increased concentration-dependent incorporation of exon in CD44 pre-mRNA by direct binding to purine-rich exonic enhancer (By similarity).
