Anti-SF3A1 Antibody Picoband® fluoro488 Vervoeging

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.

No cross-reactivity with other proteins.

E.coli-derived human SF3A1 recombinant protein (Position: K20-Q556) .

Widely expressed, with highest levels in both adult and fetal heart, ovary, uterus placenta, and bladder. In the endometrium, expressed in epithelial glands and the stroma. Also present in leukocytes. Isoform 1 is predominant in heart and skeletal muscle, whereas isoform 2 is predominant in placenta and kidney. .

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) . .
