ncbi summary :
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. [provided by RefSeq, Jul 2008]
uniprot summary :
SF3B3: Subunit of the splicing factor SF3B 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. May also be involved in the assembly of the 'E' complex. Belongs also to the minor U12-dependent spliceosome, which is involved in the splicing of rare class of nuclear pre-mRNA intron. Belongs to the RSE1 family. 3 isoforms of the human protein are produced by alternative splicing. Protein type: RNA splicing; RNA-binding; Spliceosome. Chromosomal Location of Human Ortholog: 16q22.1. Cellular Component: nucleolus; nucleoplasm; nucleus; small nuclear ribonucleoprotein complex; spliceosome; U12-dependent spliceosome. Molecular Function: protein binding; RNA binding. Biological Process: mRNA processing; negative regulation of protein catabolic process; nuclear mRNA splicing, via spliceosome; protein complex assembly; RNA splicing; RNA splicing, via transesterification reactions
