SF3A1 (Splicing Factor 3a Subunit 1) is a Protein Coding gene. Among its related pathways are mRNA Splicing - Major Pathway and Gene Expression. SF3A1 encodes a subunit of the splicing factor 3a protein complex. The splicing factor 3a heterotrimer is a component of the mature U2 small nuclear ribonucleoprotein particle (snRNP). U2 small nuclear ribonucleoproteins play a critical role in spliceosome assembly and pre-mRNA splicing.
