| + | Muscarinic acetylcholine receptors are G protein-coupled receptors that respond to acetylcholine and play important signaling roles in the nervous system. There are five muscarinic receptor subtypes (M1R to M5R), which, despite sharing a high degree of sequence identity in the transmembrane region, couple to different heterotrimeric GTP-binding proteins (G proteins) to transmit signals. M1R, M3R, and M5R couple to the Gq/ 11 family, whereas M2R and M4R couple to the Gi/ o family. Here, we present and compare the cryo-electron microscopy structures of M1R in complex with G11 and M2R in complex with GoA The M1R-G11 complex exhibits distinct features, including an extended transmembrane helix 5 and carboxyl-terminal receptor tail that interacts with G protein. Detailed analysis of these structures provides a framework for understanding the molecular determinants of G-protein coupling selectivity. | ||
