SF3B3
Lua error in Module:Infobox_gene at line 53: attempt to index field 'wikibase' (a nil value). Splicing factor 3B subunit 3 is a protein that in humans is encoded by the SF3B3 gene.[1][2]
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.[2]
Interactions
[edit | edit source]SF3B3 has been shown to interact with SF3B1,[1][3] Transcription initiation protein SPT3 homolog[4] and TAF9.[4]
