E. coli-derived recombinant human protein (amino acids R728-Q1181) was used as the immunogen for the SAP130 antibody.
Splicing factor 3B subunit 3 is a protein that in humans is encoded by the SF3B3 gene. This gene encodes subunit 3 of the splicing factor 3b protein complex. Splicing factor 3b, together with splicing factor 3a and a 12S RNA unit, forms the U2 small nucl
