KH domain-containing, RNA-binding, signal transduction-associated protein 3 (KHDRBS3)

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' theme in vitro.

Binds optimally to RNA containing 5'-[AU]UAA-3' as a bipartite motif spaced by over 15 nucleotides. Binds poly(A).
