signals by undergoing structural changes that activate internal G proteins, β-arrestins, and other transducers1 of GPCR activation has always been a challenge because G protein activation in cells occurs in less than a second, reflecting the transient nature of these active states. Twenty transition structures generated from overlapping particle subsets along this pathway provide a disrupting an ionic lock and allowing the α5 helix to start transitioning.
