    The angiotensin II receptors AT 1 R and AT 2 R serve as key components of the renin-angiotensin-aldosterone system. AT 1 R has a central role in the regulation of blood pressure, but the function of AT 2 R is unclear and it has a variety of reported effects. To identify the mechanisms that underlie the differences in function and ligand selectivity between these receptors, here we report crystal structures of human AT 2 R bound to an AT 2 R-selective ligand and to an AT 1 R/AT 2 R dual ligand, capturing the receptor in an active-like conformation. Unexpectedly, helix VIII was found in a non-canonical position, stabilizing the active-like state, but at the same time preventing the recruitment of G proteins or β-arrestins, in agreement with the lack of signalling responses in standard cellular assays. Structure-activity relationship, docking and mutagenesis studies revealed the crucial interactions for ligand binding and selectivity. Our results thus provide insights into the structural basis of the distinct functions of the angiotensin receptors, and may guide the design of new selective ligands.
