SF3B4
Splicing factor 3B subunit 4 is a protein that in humans is encoded by the SF3B4 gene.[1][2]
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. In addition to RNA-binding activity, this protein interacts directly and highly specifically with subunit 2 of the splicing factor 3B. This protein contains two N-terminal RNA-recognition motifs (RRMs), consistent with the observation that it binds directly to pre-mRNA.[2]
Interactions
SF3B4 has been shown to interact with CDC5L,[3] BMPR1A[4] and SF3B2.[5][1]
