引用ジャーナル : Nat Commun / 年 : 2023タイトル : Ligand-induced activation and G protein coupling of prostaglandin F receptor.著者 : Canrong Wu / Youwei Xu / Qian He / Dianrong Li / Jia Duan / Changyao Li / Chongzhao You / Han Chen / Weiliang Fan / Yi Jiang / H Eric Xu / 要旨 : Prostaglandin F (PGF), an endogenous arachidonic acid metabolite, regulates diverse physiological functions in many tissues and cell types through binding and activation of a G-protein-coupled ... Prostaglandin F (PGF), an endogenous arachidonic acid metabolite, regulates diverse physiological functions in many tissues and cell types through binding and activation of a G-protein-coupled receptor (GPCR), the PGF receptor (FP), which also is the primary therapeutic target for glaucoma and several other diseases. Here, we report cryo-electron microscopy (cryo-EM) structures of the human FP bound to endogenous ligand PGF and anti-glaucoma drugs LTPA and TFPA at global resolutions of 2.67 Å, 2.78 Å, and 3.14 Å. These structures reveal distinct features of FP within the lipid receptor family in terms of ligand binding selectivity, its receptor activation, and G protein coupling mechanisms, including activation in the absence of canonical PIF and ERY motifs and G coupling through direct interactions with receptor transmembrane helix 1 and intracellular loop 1. Together with mutagenesis and functional studies, our structures reveal mechanisms of ligand recognition, receptor activation, and G protein coupling by FP, which could facilitate rational design of FP-targeting drugs. 履歴 登録 2023年3月24日 - ヘッダ(付随情報) 公開 2023年7月12日 - マップ公開 2023年7月12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
