SF3b130 Polyclonal Antibody Sizes: 50μL, 100μL Catalogue Numbers: RA29758-50, RA29758-100 Citations, Manuals and MSDS Available upon request. Background: splicing factor 3b subunit 3 (SF3B3) Homo sapiens 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 nuclear ribonucleoproteins complex (U2 snRNP) . The splicing factor 3b/3a complex binds pre-mRNA upstream of the intron's branch site in a sequence independent manner and may anchor the U2 snRNP to the pre-mRNA. Splicing factor 3b is also a component of the minor U12-type spliceosome. Subunit 3 has also been identified as 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 may function in chromatin modification, transcription, splicing, and DNA repair.
