Background

Splicing factor 3 subunit 1 is a protein that in humans is encoded by the SF3A1 gene. This gene 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.

Function

Serine protease that cleaves beta-casein/CSN2 as well as several extracellular matrix (ECM) proteoglycans such as decorin/DCN, biglycan/BGN and fibronectin/FN1. Inhibits signaling mediated by TGF-beta family proteins possibly inly by degradation of these ECM proteoglycans (By similarity) . May act as a tumor suppressor. Negatively regulates, in vitro, trophoblast invasion during placental development and may be involved in the development of the placenta in vivo. May also have a role in ovarian development, granulosa cell differentiation and luteinization (PubMed:21321049, PubMed:22229724) . .
