u2 small nuclear RNA auxiliary factor 1, FP793, RN, RNu2AF1, Splicing factor u2AF 35 kDa subunit, u2 auxiliary factor 35 kDa subunit, RN, RNu2AF1, u2AF35, u2AFBP
u2AF1 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 protein is the small subunit which plays a
