引用ジャーナル : Nat Commun / 年 : 2023タイトル : Structural basis of peptide recognition and activation of endothelin receptors.著者 : Yujie Ji / Jia Duan / Qingning Yuan / Xinheng He / Gong Yang / Shengnan Zhu / Kai Wu / Wen Hu / Tianyu Gao / Xi Cheng / Hualiang Jiang / H Eric Xu / Yi Jiang / 要旨 : Endothelin system comprises three endogenous 21-amino-acid peptide ligands endothelin-1, -2, and -3 (ET-1/2/3), and two G protein-coupled receptor (GPCR) subtypes-endothelin receptor A (ETR) and B ... Endothelin system comprises three endogenous 21-amino-acid peptide ligands endothelin-1, -2, and -3 (ET-1/2/3), and two G protein-coupled receptor (GPCR) subtypes-endothelin receptor A (ETR) and B (ETR). Since ET-1, the first endothelin, was identified in 1988 as one of the most potent endothelial cell-derived vasoconstrictor peptides with long-lasting actions, the endothelin system has attracted extensive attention due to its critical role in vasoregulation and close relevance in cardiovascular-related diseases. Here we present three cryo-electron microscopy structures of ETR and ETR bound to ET-1 and ETR bound to the selective peptide IRL1620. These structures reveal a highly conserved recognition mode of ET-1 and characterize the ligand selectivity by ETRs. They also present several conformation features of the active ETRs, thus revealing a specific activation mechanism. Together, these findings deepen our understanding of endothelin system regulation and offer an opportunity to design selective drugs targeting specific ETR subtypes. 履歴 登録 2022年10月28日 - ヘッダ(付随情報) 公開 2023年3月22日 - マップ公開 2023年3月22日 - 更新 2024年11月13日 - 現状 2024年11月13日 処理サイト : RCSB / 状態 : 公開
