Splicing factor 3B subunit 4 is a protein that in humans is encoded by the SF3B4 gene.This gene encodes one of four subunits of the splicing factor 3B. The protein encoded by this gene cross-links to a region in the pre-mRNA immediately upstream of the branchpoint sequence in pre-mRNA in the prespliceosomal complex A. It also may be involved in the assembly of the B C and E spliceosomal complexes.
