![]() | ![]() Title: Fenofibrate Recognition and G Protein Coupling Mechanisms of the Human Cannabinoid Receptor CB1. Authors: Tianxin Wang / Wenqin Tang / Ziyi Zhao / Ran Zhao / Zhenyu Lv / Xuzhen Guo / Quanchang Gu / Boxiang Liu / Haoyu Lv / Jiayan Chen / Kaiquan Zhang / Fahui Li / Jiangyun Wang / ![]() Abstract: The G-protein-coupled human cannabinoid receptor 1 (CB1) is a promising therapeutic target for pain management, inflammation, obesity, and substance abuse disorders. The structures of CB1-G complexes ...The G-protein-coupled human cannabinoid receptor 1 (CB1) is a promising therapeutic target for pain management, inflammation, obesity, and substance abuse disorders. The structures of CB1-G complexes in synthetic agonist-bound forms have been resolved to date. However, the commercial drug recognition and G coupling mechanisms of CB1 remain elusive. Herein, the cryo-electron microscopy (cryo-EM) structure of CB1-G complex, in fenofibrate-bound form, at near-atomic resolution, is reported. The structure elucidates the delicate mechanisms of the precise fenofibrate recognition and G protein coupling by CB1 and will facilitate future drug discovery and design. | ||||||
