SF3B1 is 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.This gene encodes subunit 1 of the splicing factor 3b protein complex.

Alternative splicing results in multiple transcript variants encoding different isoforms.1) Beausoleil, S.A., (2004) Proc. Natl. Acad. Sci. U.S.A. 101 (33), 12130-12135.
