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. |
