SAP 155 Polyclonal Antibody Sizes: 50μL, 100μL Catalogue Numbers: RA29652-50, RA29652-100 Lead times: 1-2 weeks, if manufacturer has product in stock Manufacturer/Ship Location: China Background: splicing factor 3b subunit 1 (SF3B1) Homo sapiens This gene encodes subunit 1 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. The carboxy-terminal two-thirds of subunit 1 have 22 non-identical, tandem HEAT repeats that form rod-like, helical structures. Alternative splicing results in multiple transcript variants encoding different isoforms.
