Atrial natriuretic peptide-converting enzyme is a protein that in humans is encoded by the CORIN gene.

This gene encodes a member of the type II transmembrane serine protease class of the trypsin superfamily. Members of this family are composed of multiple structurally distinct domains. The encoded protein converts pro-atrial natriuretic peptide to biologically active atrial natriuretic peptide, a cardiac hormone that regulates blood volume and pressure. This protein may also function as a pro-brain-type natriuretic peptide convertase. [provided by RefSeq, Jul 2008].

Function: Serine-type endopeptidase involved in atrial natriuretic peptide hormone processing. Converts through proteolytic cleavage the non-functional propeptide NPPA/ANP into the active hormone which promotes natriuresis, diuresis, and vasodilatation. May also process pro-NPPB the B-type natriuretic peptide.
