Official Full Name
corin, serine peptidase
Background
Corin, also known as Atrial Natriuretic Peptide-converting enzyme, is a 1042 amino acid single-pass type II membrane protein that is found on the cell membrane. It is highly expressed in the heart and heart myocytes. Corin is a serine-type endopeptidase that is involved in atrial natriuretic peptide hormone processing. It converts, through proteolytic cleavage, the non-functional propeptide NPPA/ANP into the active hormone which promotes natriuresis, diuresis, and vasodilatation. Corin may also process pro-NPPB the B-type natriuretic peptide. Enzyme regulation is inhibited in a dose-dependent manner by non-specific trypsin-like serine protease inhibitors including benzamidine. Corin is N-glycosylated, which is required for processing and activation. It is consists of a disulfide bond that links the N- terminal propeptide and the activated Corin protease fragment. Corin is activated through proteolytic processing by a trypsin-like protease: cleaved into an N-terminal propeptide and an activated Corin protease fragment. It is initially named Corin due to its abundant expression in the heart.
