Constitutively activates the G(s)-alpha/cAMP signaling pathway (PubMed:28827538). Shows a reciprocal regulatory interaction with the melatonin receptor MTNR1B most likely through receptor heteromerization (PubMed:28827538). May be involved in the regulation of food intake and body weight (By similarity).[UniProtKB:Q8C010] C562_ECOLX Electron-transport protein of unknown function. Publication Abstract from PubMed GPR61 is a class A orphan G protein-coupled receptor (GPCR) that is predominantly expressed in the pituitary gland and appetite-regulating centers of the brain. Genome-wide association analysis, epigenetic analysis, and animal model data have suggested that GPR61 could be a potential therapeutic target for appetite and body weight modulation. Herein, we describe our medicinal chemistry efforts in discovering a class of potent, selective, and brain-penetrant GPR61 inverse agonists. The cryogenic electron microscopy structure of GPR61 bound to compound 15 shows that this class of inverse agonists binds to an induced, intracellular, allosteric pocket and abolishes GPR61 constitutive activity by disrupting its interactions with G protein, representing a novel mode of action of GPCR inverse agonism.
