Splicing factor U2AF 35 kDa subunit is a protein that in humans is encoded by the U2AF1 gene.[3][4][5]

Function

This gene belongs to the splicing factor SR family of genes. U2 auxiliary factor, comprising a large and a small subunit, is a non-snRNP protein required for the binding of U2 snRNP to the pre-mRNA branch site. This gene encodes the small subunit which plays a critical role in both constitutive and enhancer-dependent RNA splicing by directly mediating interactions between the large subunit and proteins bound to the enhancers. Alternatively spliced transcript variants encoding different isoforms have been identified.[5]

U2 small nuclear RNA auxiliary factor 1 has been shown to interact with:
