Using cryo-electron microscopy, we determined the structures of the human glucagon receptor (GCGR) bound to glucagon and distinct classes of heterotrimeric G proteins, G or G These two structures adopt a similar open binding cavity to accommodate G and G The G binding selectivity of GCGR is explained by a larger interaction interface, but there are specific interactions that affect G more than G binding. Conformational differences in the receptor intracellular loops were found to be key selectivity determinants. These distinctions in transducer engagement were supported by mutagenesis and functional studies. | |||||||||||||||||||||||||||
