The signaling mechanisms of the angiotensin II type 2 receptor (AT2R), a heptahelical receptor, have not yet been clearly and completely defined. In the present contribution, we set out to identify the molecular determinants involved in AT2R activation. Although AT2R has not been shown to engage Gq/11, G12, Gi2, and β-arrestin (βarr) pathways as does the AT1R upon angiotensin II (AngII) stimulation, the atypical positioning of helix VIII in the recently published AT2R structure may play a role in the receptor's capacity to couple to downstream effectors. In the AT2R structure, helix VIII points inwards and towards intracellular loop 3 (ICL3) to form tertiary interactions with transmembrane domain 6 (TM6), possibly impeding access to signaling effectors. On the other hand, in most class A GPCRs, helix VIII is found to be engaged in tertiary interactions with ICL1 and away from the effector binding site. Upon closer examination of the AT2R structure, we found that the residues contained within intracellular loop 1 (ICL1) may be involved in driving this unusual conformation of helix VIII. To explore this hypothesis, we designed a series of AT1R/AT2R receptor chimeras to validate the roles of ICL1 and helix VIII in AT2R signaling. Substituting the AT1R ICL1 into AT2R led to a mutant receptor that coupled to Gi2. The substitution of the helix VIII and C-terminal domains of AT2R into the AT1R backbone led to a mutant receptor that retained AT1R-like signaling properties. These results suggest that the C-terminal portion of AT2R is compatible with canonical GPCR signaling and that ICL1 of AT2R is involved in repositioning helix VIII, which impedes engagement of classical GPCR effectors such as G proteins or βarrs.
