Here, we report three crystal ... Cholecystokinin receptors, CCKR and CCKR, are important neurointestinal peptide hormone receptors and play a vital role in food intake and appetite regulation. Here, we report three crystal structures of the human CCKR in complex with different ligands, including one peptide agonist and two small-molecule antagonists, as well as two cryo-electron microscopy structures of CCKR-gastrin in complex with G and G, respectively. These structures reveal the recognition pattern of different ligand types and the molecular basis of peptide selectivity in the cholecystokinin receptor family. By comparing receptor structures in different conformational states, a stepwise activation process of cholecystokinin receptors is proposed. Combined with pharmacological data, our results provide atomic details for differential ligand recognition and receptor activation mechanisms. These insights will facilitate the discovery of potential therapeutics targeting cholecystokinin receptors. 履歴 登録 2021年7月2日 - ヘッダ(付随情報) 公開 2021年10月13日 - マップ公開 2021年10月13日 - 更新 2022年2月16日 - 現状 2022年2月16日 処理サイト : PDBj / 状態 : 公開
