C-type natriuretic peptide (CNP) shares structural homology with A-type natriuretic peptide (ANP). Unlike ANP, which inhibits experimentally induced water drinking, CNP stimulates intake under similar conditions. The action of CNP to stimulate water drinking is not due to competition with ANP for the clearance receptor which recognizes both peptides since the ligand specific for that binding site, C-ANF 4-23, like ANP, inhibits water drinking under the same conditions.
C型利钠肽(CNP)与A型利钠肽(ANP)具有结构同源性。与抑制实验诱导饮水的ANP不同,CNP在类似条件下会刺激饮水。CNP刺激饮水的作用并非由于与ANP竞争识别这两种肽的清除受体,因为该结合位点的特异性配体C-ANF 4-23与ANP一样,在相同条件下会抑制饮水。
