Anti-SF3A3 antibody,Abcam,AB176581

Target data 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). See full target information SF3A3
