Description_x000D_ General description_x000D_ U2AF1 belongs to the splicing factor SR family. 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._x000D_ Immunogen_x000D_ U2AF1 (NP_006749, 60-93)_x000D_ This antibody is generated from rabbits immunized with a KLH conjugated synthetic peptide selected from the Center region of human U2AF1._x000D_ Physical form_x000D_ Purified polyclonal antibody supplied in PBS with 0.09% (W/V) sodium azide.
