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 G family, whereas M2R and M4R couple to the G family. Here, we present and compare the cryo-electron microscopy structures of M1R in complex with G and M2R in complex with G The M1R-G 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. 履歴 登録 2019年4月9日 - ヘッダ(付随情報) 公開 2019年5月1日 - マップ公開 2019年5月8日 - 更新 2020年1月8日 - 現状 2020年1月8日 処理サイト : RCSB / 状態 : 公開
