Kisspeptin receptor (KISS1R), belonging to the class A peptide-GPCR family, plays a key role in the regulation of reproductive physiology after stimulation by kisspeptin and is regarded as an attractive drug target for reproductive diseases. Here, we demonstrated that KISS1R can couple to the G pathway besides the well-known G pathway. We further resolved the cryo-electron microscopy (cryo-EM) structure of KISS1R-G and KISS1R-G complexes bound to the synthetic agonist TAK448 and structure of KISS1R-G complex bound to the endogenous agonist KP54. The high-resolution structures provided clear insights into mechanism of KISS1R recognition by its ligand and can facilitate the design of targeted drugs with high affinity to improve treatment effects. Moreover, the structural and functional analyses indicated that conformational differences in the extracellular loops (ECLs), intracellular loops (ICLs) of the receptor, and the "wavy hook" of the Gα subunit may account for the specificity of G protein coupling for KISS1R signaling. 履歴 登録 2023年12月15日 - ヘッダ(付随情報) 公開 2024年10月30日 - マップ公開 2024年10月30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
