Here, we report that the androgen 5α-DHT activates membrane receptor GPR133 in muscle cells, thereby increasing intracellular cyclic AMP (cAMP) levels and enhancing muscle strength. Further cryoelectron microscopy (cryo-EM) structural analysis of GPR133-Gs in complex with 5α-DHT or its derivative methenolone (MET) reveals the structural basis for androgen recognition. Notably, the presence of the "Φ(F/L)-F-W" and the "F××N/D" motifs, which recognize the hydrophobic steroid core and polar groups, respectively, are common in adhesion GPCRs (aGPCRs), suggesting that many aGPCRs may recognize different steroid hormones. Finally, we exploited in silico screening methods to identify a small molecule, AP503, which activates GPR133 and separates the beneficial muscle-strengthening effects from side effects mediated by AR. Thus, GPR133 represents an androgen membrane receptor that contributes to normal androgen physiology and has important therapeutic potentials. #1: ![]() タイトル: Structural basis for the tethered peptide activation of adhesion GPCRs. 著者: Yu-Qi Ping / Peng Xiao / Fan Yang / Ru-Jia Zhao / Sheng-Chao Guo / Xu Yan / Xiang Wu / Chao Zhang / Yan Lu / Fenghui Zhao / Fulai Zhou / Yue-Tong Xi / Wanchao Yin / Feng-Zhen Liu / Dong-Fang ...著者: Yu-Qi Ping / Peng Xiao / Fan Yang / Ru-Jia Zhao / Sheng-Chao Guo / Xu Yan / Xiang Wu / Chao Zhang / Yan Lu / Fenghui Zhao / Fulai Zhou / Yue-Tong Xi / Wanchao Yin / Feng-Zhen Liu / Dong-Fang He / Dao-Lai Zhang / Zhong-Liang Zhu / Yi Jiang / Lutao Du / Shi-Qing Feng / Torsten Schöneberg / Ines Liebscher / H Eric Xu / Jin-Peng Sun / ![]() ![]() 要旨: Adhesion G-protein-coupled receptors (aGPCRs) are important for organogenesis, neurodevelopment, reproduction and other processes.

Many aGPCRs are activated by a conserved internal (tethered) agonist sequence known as the Stachel sequence. Here, we report the cryogenic electron microscopy (cryo-EM) structures of two aGPCRs in complex with G: GPR133 and GPR114. The structures indicate that the Stachel sequences of both receptors assume an α-helical-bulge-β-sheet structure and insert into a binding site formed by the transmembrane domain (TMD). A hydrophobic interaction motif (HIM) within the Stachel sequence mediates most of the intramolecular interactions with the TMD. Combined with the cryo-EM structures, biochemical characterization of the HIM motif provides insight into the cross-reactivity and selectivity of the Stachel sequences. Two interconnected mechanisms, the sensing of Stachel sequences by the conserved 'toggle switch' W and the constitution of a hydrogen-bond network formed by Q/Y and the P/VφφG motif (φ indicates a hydrophobic residue), are important in Stachel sequence-mediated receptor activation and G coupling. Notably, this network stabilizes kink formation in TM helices 6 and 7 (TM6 and TM7, respectively). A common G-binding interface is observed between the two aGPCRs, and GPR114 has an extended TM7 that forms unique interactions with G. Our structures reveal the detailed mechanisms of aGPCR activation by Stachel sequences and their G coupling. | ||||||
