C-type natriuretic peptide

Jump to: navigation, search

C-type Natriuretic peptide (CNP)is a 22 amino acid peptide that has strong vasorelaxant properties. Unlike ANP and BNP, CNP does not have direct natriuretic activity. This is due to the fact that CNP is a selective agonist for the B-type Natriuretic receptor (NPRB) whereas ANP and BNP are selective for NPRA.
