Recombinant Human Corin protein (GST tag N-Terminus)

一般的な情報

機能

Serine-type endopeptidase involved in atrial natriuretic peptide (NPPA) and brain natriuretic peptide (NPPB) processing (PubMed : 10880574, PubMed : 20489134, PubMed : 21288900, PubMed : 21763278). Converts through proteolytic cleavage the non-functional propeptides NPPA and NPPB into their active hormones, ANP and BNP(1-32) respectively, thereby regulating blood pressure in the heart and promoting natriuresis, diuresis and vasodilation (PubMed : 10880574, PubMed : 20489134, PubMed : 21288900, PubMed : 21763278). Proteolytic cleavage of pro-NPPA also plays a role in female pregnancy by promoting trophoblast invasion and spiral artery remodeling in uterus (PubMed : 22437503). Also acts as a regulator of sodium reabsorption in kidney (By similarity).. Isoform 2. Has weaker endopeptidase activity compared to isoform 1.

翻訳後修飾

N-glycosylated; required for processing and activation.. Activated through proteolytic processing by a trypsin-like protease; cleaved into a N-terminal propeptide and an activated corin protease fragment. Different soluble forms are produced by cleavage and autocatalytic cleavage: Atrial natriuretic peptide-converting enzyme, 180 kDa soluble fragment is produced by cleavage by ADAM10, while 160 kDa and 100 kDa soluble fragments are produced by autocatalytic cleavage. Cleavage by ADAM10 to produce soluble 180 kDa soluble fragment takes place after the transmembrane region and before FZ 1.. A disulfide bond links the activated corin protease fragment and the N-terminal propeptide. The disulfide bond also links the activated corin protease fragment with soluble fragments (100 kDa, 160 kDa and 180 kDa fragments).
