Natriuretic peptide precursor C, also known as NPPC, is a protein that in humans is encoded by the NPPCgene.[5][6][7] The precursor NPPC protein is cleaved to the 22 amino acidpeptideC-type natriuretic peptide (CNP).
Natriuretic peptides comprise a family of 3 structurally related molecules: atrial natriuretic peptide (ANP), brain natriuretic peptide (BNP), and C-type natriuretic peptide (CNP), encoded by a gene symbolized NPPC. These peptides possess potent natriuretic, diuretic, and vasodilating activities and are implicated in body fluid homeostasis and blood pressure control.[5] Unlike ANP and BNP, CNP does not have direct natriuretic activity. This is because CNP is a selective agonist for the B-type natriuretic receptor (NPRB) whereas ANP and BNP are selective for the A-type natriuretic receptor (NPRA).[8] It is synthesized and secreted from the endothelium in response to many stimuli, for example shear stress (like NO[clarification needed]) and certain proinflammatory cytokines.[9]
