Question: what is angiotensin 2 receptor?
Answer: The angiotensin II receptors, (AGTR1) and (AGTR2), are a class of G protein-coupled receptors with angiotensin II as their ligands. They are important in the renin–angiotensin system: they are responsible for the signal transduction of the vasoconstricting stimulus of the main effector hormone, angiotensin II.
