The adenosine A receptor (AAR), a key member of the G protein-coupled receptor family, is a promising therapeutic target for inflammatory and cancerous conditions. The selective AAR agonists, CF101 and CF102, are clinically significant, yet their recognition mechanisms remained elusive. Here we report the cryogenic electron microscopy structures of the full-length human AAR bound to CF101 and CF102 with heterotrimeric G protein in complex at 3.3-3.2 Å resolution. These agonists reside in the orthosteric pocket, forming conserved interactions via their adenine moieties, while their 3-iodobenzyl groups exhibit distinct orientations. Functional assays reveal the critical role of extracellular loop 3 in AAR's ligand selectivity and receptor activation. Key mutations, including His, Ser, and Ser, in a unique sub-pocket of AAR, significantly impact receptor activation. Comparative analysis with the inactive AAR structure highlights a conserved receptor activation mechanism. Our findings provide comprehensive insights into the molecular recognition and signaling of AAR, paving the way for designing subtype-selective adenosine receptor ligands. 履歴 登録 2023年11月6日 - ヘッダ(付随情報) 公開 2024年4月24日 - マップ公開 2024年4月24日 - 更新 2024年10月23日 - 現状 2024年10月23日 処理サイト : PDBj / 状態 : 公開
