U2AF1

U2 small nuclear RNA auxiliary factor 1

Plays a critical role in both constitutive and enhancer-dependent splicing by mediating protein-protein interactions and protein-RNA interactions required for accurate 3'-splice site selection. Recruits U2 snRNP to the branch point. Directly mediates interactions between U2AF2 and proteins bound to the enhancers and thus may function as a bridge between U2AF2 and the enhancer complex to recruit it to the adjacent intron.

Gene Name: U2 small nuclear RNA auxiliary factor 1
Synonyms: U2AF1, FP793, U2AF35, U2AFBP, RNU2AF1, RN
Target Sequences: NM_006758 NP_006749.1 Q01081
