Background

Function：Component of the 17S U2 SnRNP complex of the spliceosome, a large ribonucleoprotein complex that removes introns from transcribed pre-mRNAs (PubMed:10882114, PubMed:11533230, PubMed:32494006, PubMed:34822310, PubMed:8022796). The 17S U2 SnRNP complex (1) directly participates in early spliceosome assembly and (2) mediates recognition of the intron branch site during pre-mRNA splicing by promoting the selection of the pre-mRNA branch-site adenosine, the nucleophile for the first step of splicing (PubMed:10882114, PubMed:11533230, PubMed:32494006, PubMed:34822310). Within the 17S U2 SnRNP complex, SF3A3 is part of the SF3A subcomplex that contributes to the assembly of the 17S U2 snRNP, and the subsequent assembly of the pre-spliceosome 'E' complex and the pre-catalytic spliceosome 'A' complex (PubMed:10882114, PubMed:11533230). Involved in pre-mRNA splicing as a component of pre-catalytic spliceosome 'B' complexes (PubMed:29360106, PubMed:30315277)

Subcellular Localization：Nucleus speckle; Nucleus

Expression：
Tissue_specificity:Ubiquitous

Subunit：Component of the 17S U2 SnRNP complex, a ribonucleoprotein complex that contains small nuclear RNA (snRNA) U2 and a number of specific proteins (PubMed:21349847, PubMed:32494006, PubMed:34822310, PubMed:36797247). Part of the SF3A subcomplex of the 17S U2 SnRNP complex which is composed of three subunits; SF3A3/SAP61, SF3A2/SAP62 and SF3A1/SAP114 (PubMed:10882114, PubMed:11533230, PubMed:17098193, PubMed:21349847, PubMed:8022796). SF3A associates with the splicing factor SF3B and a 12S RNA unit to form the mature 17S U2 small nuclear ribonucleoprotein complex (17S U2 snRNP) (PubMed:10882114, PubMed:11533230). Identified in the spliceosome 'E' complex, a precursor of the spliceosome 'A' complex (PubMed:10882114). Identified in the spliceosome 'A' and 'B' complexes (PubMed:10882114, PubMed:29360106, PubMed:30315277, PubMed:8022796). Identified in the spliceosome 'C' complex (PubMed:11991638)
