Anti-Splicing factor 3B subunit 2 SF3B2 Antibody

The antibody was affinity-purified from rabbit antiserum by affinity-chromatography using epitope-specific immunogen and the purity is > 95% (by SDS-PAGE) .

Involved in pre-mRNA splicing as a component of the splicing factor SF3B complex (PubMed:27720643) . SF3B complex is required for 'A' complex assembly formed by the stable binding of U2 snRNP to the branchpoint sequence (BPS) in pre-mRNA. Sequence independent binding of SF3A/SF3B complex upstream of the branch site is essential, it may anchor U2 snRNP to the pre-mRNA (PubMed:12234937) . May also be involved in the assembly of the 'E' complex (PubMed:10882114) . Belongs also to the minor U12-dependent spliceosome, which is involved in the splicing of rare class of nuclear pre-mRNA intron (PubMed:15146077) .
