Summaries for SF3B2 Gene

Entrez Gene Summary for SF3B2 Gene

  • This gene encodes subunit 2 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 2 associates with pre-mRNA upstream of the branch site at the anchoring site. Subunit 2 also interacts directly with subunit 4 of the splicing factor 3b complex. Subunit 2 is a highly hydrophilic protein with a proline-rich N-terminus and a glutamate-rich stretch in the C-terminus. [provided by RefSeq, Jul 2008]

GeneCards Summary for SF3B2 Gene

SF3B2 (Splicing Factor 3b Subunit 2) is a Protein Coding gene. Diseases associated with SF3B2 include Hiv-1. Among its related pathways are mRNA Splicing - Major Pathway and mRNA Splicing - Minor Pathway. GO annotations related to this gene include nucleic acid binding and poly(A) RNA binding.

UniProtKB/Swiss-Prot for SF3B2 Gene

  • 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.
