MSH: Oligopeptides which are important in the regulation of blood pressure (VASOCONSTRICTION) and fluid homeostasis via the RENIN-ANGIOTENSIN SYSTEM. These include angiotensins derived naturally from precursor ANGIOTENSINOGEN, and those synthesized.,CSP: angiotensin I, an inactive decapeptide, is cleaved by angiotensin converting enzyme to form the octapeptide angiotensin II, a powerful vasopressor, which is then cleaved to the heptapeptide angiotensin III, an aldosterone stimulant.,NCI: Expressed in liver by human AGT Gene (Serpin Family), secreted 485-aa 53-kDa Angiotensinogen is cleaved by renin (in response to lowered blood pressure) to inactive decapeptide Angiotensin I, which is cleaved by ACE to generate active octapeptide vasopressor Angiotensin II (maintains blood pressure and regulates the volume and mineral balance of body fluids). Angiotensin II is cleaved to Angiotensin III heptapeptide, an aldosterone stimulant.
