U2 small nuclear ribonucleoprotein A family

DESCRIPTION

Also known as RU2A_HUMAN, SNRPA1. Involved in pre-mRNA splicing as component of the spliceosome (PubMed:11991638, PubMed:28502770, PubMed:28781166, PubMed:28076346, PubMed:27035939). Associated with sn-RNP U2, where it contributes to the binding of stem loop IV of U2 snRNA (PubMed:9716128, PubMed:27035939). Identified in the spliceosome B complex (PubMed:28781166). Identified in the spliceosome C complex (PubMed:11991638, PubMed:28502770, PubMed:28076346). Found in a pre-mRNA splicing complex with SFRS4, SFRS5, SNRNP70, SNRPA1, SRRM1 and SRRM2 (PubMed:9531537). Found in a pre-mRNA exonic splicing enhancer (ESE) complex with SNRNP70, SNRPA1, SRRM1 and TRA2B (PubMed:10339552). Contributes to the binding of stem loop IV of U2 snRNA with SNRPB2 (PubMed:9716128, PubMed:27035939).
