Receptor for angiotensin II, a vasoconstricting peptide (PubMed:8227011). Signals primarily via a non-canonical G-protein- and beta-arrestin independent pathways. Cooperates with MTUS1 to inhibit ERK2 activation and cell proliferation (By similarity). Interacts with MTUS1. Abundant expression in fetal tissues, immature brain, skin wound and atretic ovarian follicles. Abundant in whole fetus but decreases rapidly after birth. In adults is highly expressed in the adrenal, present in the brain and uterus but undetectable in the heart. Helix VIII may act as a gatekeeper for either suppression or activation of the receptor, depending on post-translational modifications and interactions with various receptor partners. Helix VIII is found in a non-canonical position, stabilizing the active-like state, but at the same time preventing the recruitment of G-proteins or beta-arrestins. Upon switching to a membrane-bound conformation, helix VIII can support the recruitment of G proteins and beta-arrestins. Belongs to the G-protein coupled receptor 1 family.
