Protein Information
Name SF3B3
Synonyms KIAA0017, SAP130 {ECO:0000303|PubMed:104
Function Involved in pre-mRNA splicing as a component of the splicing factor SF3B complex, a constituent of the spliceosome (PubMed:10490618, PubMed:10882114, PubMed:27720643, PubMed:28781166). 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).

This gene encodes subunit 3 of the splicing factor 3bprotein complex. Splicing factor 3b, together with splicing factor3a and a 12S RNA unit, forms the U2 small nuclearribonucleoproteins complex (U2 snRNP). The splicing factor 3b/3acomplex binds pre-mRNA upstream of the intron's branch site in asequence independent manner and may anchor the U2 snRNP to thepre-mRNA. Splicing factor 3b is also a component of the minorU12-type spliceosome. Subunit 3 has also been identified as acomponent of the STAGA (SPT3-TAF(II)31-GCN5L acetylase)transcription coactivator-HAT (histone acetyltransferase) complex,and the TFTC (TATA-binding-protein-free TAF(II)-containingcomplex). These complexes may function in chromatin modification,transcription, splicing, and DNA repair.
