Method: Electron Microscopy, Resolution 2.32Å Ligands: 7LD Resources: FirstGlance, OCA, PDBe, RCSB, PDBsum, ProSAT Function GBB1_HUMAN Guanine nucleotide-binding proteins (G proteins) are involved as a modulator or transducer in various transmembrane signaling systems. The beta and gamma chains are required for the GTPase activity, for replacement of GDP by GTP, and for G protein-effector interaction. Publication Abstract from PubMed The classical psychedelics (+)-lysergic acid diethylamide (LSD), psilocybin, and mescaline exert their psychedelic effects via activation of the 5-HT(2A) serotonin receptor (5-HT(2A)R). Recent clinical studies have suggested that classical psychedelics may additionally have therapeutic potential for many neuropsychiatric conditions including depression, anxiety, migraine and cluster headaches, drug abuse, and post-traumatic stress disorder. In this study, we investigated the pharmacology of 41 classical psychedelics from the tryptamine, phenethylamine, and lysergamide chemical classes. We profiled these compounds against 318 human G-protein-coupled receptors (GPCRs) to elucidate their target profiles, and in the case of LSD, against more than 450 human kinases. We found that psychedelics have potent and efficacious actions at nearly every serotonin, dopamine, and adrenergic receptor. We quantified their activation for multiple transducers and found that psychedelics stimulate multiple 5-HT(2A)R transducers, each of which correlates with psychedelic drug-like actions in vivo. Our results suggest that multiple molecular targets likely contribute to the actions of psychedelics. The polypharmacology of psychedelics reveals multiple targets for potential therapeutics.,Jain MK, Gumpper RH, Slocum ST, Schmitz GP, Madsen JS, Tummino TA, Suomivuori CM, Huang XP, Shub L, DiBerto JF, Kim K, DeLeon C, Krumm BE, Fay JF, Keiser M, Hauser AS, Dror RO, Shoichet B, Gloriam DE, Nichols DE, Roth BL Neuron. 2025 Jul 15:S0896-6273(25)00470-2. doi: 10.1016/j.neuron.2025.06.012.
