Corin was first described as a trypsin-like serine proteinase in the heart which processed pro-atrial natriuretic peptide into the active form ANP. Corin cleaves pro-ANP at Arg98/Ser-99, and blocking Corin message inhibits pro-ANP processing. Null mutant mice lacking Corin develop hypertension, and a series of missense mutations have been identified in humans with high blood pressure and hypertension. Corin is a member of the type-II transmembrane serine proteinases, such as Hepsin, Epitheliasin, Matriptase and enteropeptidase. The Corin domain structure includes a cytoplasmic domain, a transmembrane domain, a spacer region, a frizzled-like domain, 5 LDL Receptor-like domains, another frizzled-like domain, 3 more LDLR-like repeats, a SRCR (Scavenger Receptor-Cysteine Rich) domain (also called macrophage scavenger-like domain), and finally the trypsin-like serine proteinase domain. The complex domain structure puts Corin into the “mosaic” TMPRSS family, so named because of the wide variety of domains.

功能
Serine-type endopeptidase involved in atrial natriuretic peptide hormone (NPPA) processing. Converts through proteolytic cleavage the non-functional propeptide NPPA into the active hormone, thereby regulating blood pressure in heart and promoting natriuresis, diuresis and vasodilation. Proteolytic cleavage of pro-NPPA also plays a role in female pregnancy by promoting trophoblast invasion and spiral artery remodeling in uterus. Also acts as a regulator of sodium reabsorption in kidney. May also process pro-NPPB the B-type natriuretic peptide. Isoform 2: has weaker endopeptidase activity compared to isoform 1.
