Molecular mechanisms underlying ... The antidiuretic hormone arginine-vasopressin (AVP) forms a signaling complex with the V2 receptor (V2R) and the G protein, promoting kidney water reabsorption. Molecular mechanisms underlying activation of this critical G protein-coupled receptor (GPCR) signaling system are still unknown. To fill this gap of knowledge, we report here the cryo-electron microscopy structure of the AVP-V2R-G complex. Single-particle analysis revealed the presence of three different states. The two best maps were combined with computational and nuclear magnetic resonance spectroscopy constraints to reconstruct two structures of the ternary complex. These structures differ in AVP and G binding modes. They reveal an original receptor-G interface in which the Gα subunit penetrates deep into the active V2R. The structures help to explain how V2R R137H or R137L/C variants can lead to two severe genetic diseases. Our study provides important structural insights into the function of this clinically relevant GPCR signaling complex. 履歴 登録 2020年12月17日 - ヘッダ(付随情報) 公開 2021年6月2日 - マップ公開 2021年6月2日 - 更新 2024年10月23日 - 現状 2024年10月23日 処理サイト : PDBe / 状態 : 公開
