Angiotensin II

Octapeptide (Asp-Arg-Val-Tyr-Ile-His-Pro-Phe; MW 1046); RAAS effector produced by ACE from Ang I. Acts via AT1R (vasoconstriction, aldosterone, Na⁺ retention, cardiac hypertrophy) and AT2R (counter-regulatory). Key target of ACEi and ARBs.

Also known as: AngII, Ang II, angiotensin-2, AII, vasoconstrictor octapeptide
