引用 | ジャーナル: Cell Rep / 年: 2024 タイトル: Structural basis for ligand recognition and activation of the prostanoid receptors. 著者: Xiu Li / Xuan Zhang / Xin Wen / Daolai Zhang / Changxiu Qu / Xinyi Miao / Wenkai Zhang / Ru Zhang / Guibing Liu / Peng Xiao / Jin-Peng Sun / Weimin Gong / 要旨: Prostaglandin F (PGF) and thromboxane A (TXA) are endogenous arachidonic acid metabolites, modulating diverse physiological processes including inflammation and cardiovascular homeostasis through ...Prostaglandin F (PGF) and thromboxane A (TXA) are endogenous arachidonic acid metabolites, modulating diverse physiological processes including inflammation and cardiovascular homeostasis through activating PGF receptor (FP) and TXA receptor (TP). Ligands targeting FP and TP have demonstrated efficacy in treating conditions like glaucoma and cardiovascular diseases in humans, as well as reproductive-related diseases in animals. Here, we present five cryoelectron microscopy structures illustrating FP and TP in complex with G and bound to PGF (endogenous ligand), latanoprost acid (a clinical drug), and two other synthetic agonists. Combined with mutational and functional studies, these structures reveal not only structural features for the specific recognition of endogenous ligands and attainment of receptor selectivity of FP and TP but also the common mechanisms of receptor activation and G protein coupling. The findings may enrich our knowledge of ligand recognition and signal transduction of the prostanoid receptor family and facilitate rational ligand design toward these two receptors. | |||||||||
