Corin, also called atrial natriuretic peptide-converting enzyme, is a protein that in humans is encoded by the CORIN gene. [5] [6]

Contents

Protein

Human corin, a polypeptide of 1042 amino acids, consists of an N-terminal cytoplasmic domain, a transmembrane domain and an extracellular region with two frizzled-like domains, eight LDL receptor-like domains, a scavenger receptor-like domain and a C-terminal trypsin-like serine protease domain. [5] [7] Corin is synthesized as a zymogen that is activated by PCSK6. [8]

Corin exhibits a trypsin-like catalytic activity favoring basic residues at the P1 position. [9]

Human corin contains 19 N-glycosylation sites. [5] N-glycans promote corin expression on the cell surface and protect corin from metalloproteinase-mediated shedding. [10] [11] [12]

Function

Corin converts the atrial natriuretic peptide (ANP) precursor, pro-ANP, to mature ANP, a cardiac hormone that regulates salt-water balance and blood pressure. [13] In mice, corin deficiency prevents pro-ANP processing and causes salt-sensitive hypertension. [14] [15]

Corin may also function as a pro-brain-type natriuretic peptide convertase. [13] [16] [17]

Corin-mediated ANP production in the pregnant uterus promotes spiral artery remodeling and trophoblast invasion. [18] CORIN mutations have been reported in patients with preeclampsia. [18] [19]

In mice, corin functions in the dermal papilla to regulate coat color in an Agouti-dependent pathway. [20]

Variants and mutations

Variants encoded by alternative exons were reported in human and mouse corin. [21] A variant allele (T555I/Q568P) was found in African Americans with hypertension and cardiac hypertrophy. [22] [23] The amino acid substitutions impaired corin activity. [24] [25] An insertion variant in exon 1 alters the cytoplasmic tail. [26] This variant appeared more frequently in hypertensive patients. CORIN mutations were found in patients with hypertension. [27] [18] [19] [28]

Atrial Natriuretic Peptide (ANP) or atrial natriuretic factor (ANF) is a natriuretic peptide hormone secreted from the cardiac atria that in humans is encoded by the NPPA gene. Natriuretic peptides are a family of hormone/paracrine factors that are structurally related. The main function of ANP is causing a reduction in expanded extracellular fluid (ECF) volume by increasing renal sodium excretion. ANP is synthesized and secreted by cardiac muscle cells in the walls of the atria in the heart. These cells contain volume receptors which respond to increased stretching of the atrial wall due to increased atrial blood volume.

<span class="mw-page-title-main">Enteropeptidase</span> Class of enzymes

Enteropeptidase is an enzyme produced by cells of the duodenum and is involved in digestion in humans and other animals. Enteropeptidase converts trypsinogen into its active form trypsin, resulting in the subsequent activation of pancreatic digestive enzymes. Absence of enteropeptidase results in intestinal digestion impairment.

<span class="mw-page-title-main">Catalytic triad</span> Set of three coordinated amino acids

A catalytic triad is a set of three coordinated amino acids that can be found in the active site of some enzymes. Catalytic triads are most commonly found in hydrolase and transferase enzymes. An acid-base-nucleophile triad is a common motif for generating a nucleophilic residue for covalent catalysis. The residues form a charge-relay network to polarise and activate the nucleophile, which attacks the substrate, forming a covalent intermediate which is then hydrolysed to release the product and regenerate free enzyme. The nucleophile is most commonly a serine or cysteine amino acid, but occasionally threonine or even selenocysteine. The 3D structure of the enzyme brings together the triad residues in a precise orientation, even though they may be far apart in the sequence.
