Corin (CRN) Antibody – Rabbit Polyclonal

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. Multiple alternatively spliced transcript variants encoding different isoforms have been found for this gene.

CORIN: 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. Defects in CORIN are the cause of pre-eclampsia/eclampsia 5 (PEE5); also known as gestational proteinuric hypertension. Preeclampsia is a pregnancy-associated disease with maternal symptoms but placental origin. Unlike most other human disorders, it impacts 2 individuals, the mother and her child, both of whom can be severely affected. Belongs to the peptidase S1 family. 2 isoforms of the human protein are produced by alternative splicing.
