引用ジャーナル : Commun Biol / 年 : 2024タイトル : Structure of endothelin ET receptor-G complex in a conformation stabilized by unique NPxxL motif.著者 : Kazutoshi Tani / Saori Maki-Yonekura / Ryo Kanno / Tatsuki Negami / Tasuku Hamaguchi / Malgorzata Hall / Akira Mizoguchi / Bruno M Humbel / Tohru Terada / Koji Yonekura / Tomoko Doi / 要旨 : Endothelin type B receptor (ETR) plays a crucial role in regulating blood pressure and humoral homeostasis, making it an important therapeutic target for related diseases. ETR activation by the ... Endothelin type B receptor (ETR) plays a crucial role in regulating blood pressure and humoral homeostasis, making it an important therapeutic target for related diseases. ETR activation by the endogenous peptide hormones endothelin (ET)-1-3 stimulates several signaling pathways, including G, G, G, G, and β-arrestin. Although the conserved NPxxY motif in transmembrane helix 7 (TM7) is important during GPCR activation, ETR possesses the lesser known NPxxL motif. In this study, we present the cryo-EM structure of the ETR-G complex, complemented by MD simulations and functional studies. These investigations reveal an unusual movement of TM7 to the intracellular side during ETR activation and the essential roles of the diverse NPxxL motif in stabilizing the active conformation of ETR and organizing the assembly of the binding pocket for the α5 helix of G protein. These findings enhance our understanding of the interactions between GPCRs and G proteins, thereby advancing the development of therapeutic strategies. 履歴 登録 2024年6月5日 - ヘッダ(付随情報) 公開 2024年10月2日 - マップ公開 2024年10月2日 - 更新 2024年10月30日 - 現状 2024年10月30日 処理サイト : PDBj / 状態 : 公開
