Anti-SAP130 Antibody, clone 1YO 1B10

SAP130, also known as Splicing factor 3B subunit 3, is part of the RNA splicing machinery. It is expressed by the Sf3b3 gene and encodes subunit 3 of the splicing factor 3b protein complex. As a component of this protein complex, it is associated with U2 snRNP and recruited to prespliceosomal complexes. Splicing factor 3b along with splicing factor 3a and a 12S RNA, form the U2 small nuclear ribonucleoprotein complex (U2 snRNP). In pre-mRNA’s, the splicing factor 3b/3a complex binds upstream of intron branch sites possibly anchoring the U2 snRNP to the pre-mRNA.
SAP130 is also a component of the STAGA (SPT3-TAF(II)31-GCN5L acetylase) transcription coactivator-HAT (histone acetyltransferase) complex, and the TFTC (TATA-binding-protein-free TAF(II)-containing complex). These complexes are believed to function in chromatin modification, transcription, splicing, and DNA repair.
