Abstract
The study of orphan G protein-coupled receptors (GPCRs) holds much promise for increasing our understanding of neuropsychiatric diseases and for the development of new therapeutic strategies for these diseases. GPR139 is an orphan GPCR expressed in the central nervous system, especially in areas of the brain that control movement, motivation, and reward, and those that regulate neuropsychiatric behaviour. This review provides information about the discovery, tissue expression, signal transduction pathways, and physiological functions of GPR139, as well as how GPR139 interacts with other GPCRs, which form heteromeric complexes that affect their pharmacology and function. We also discuss the utility and therapeutic potential of ligands that target GPR139, including the pharmacological properties of reported agonists and antagonists. Finally, we highlight the pathologic role of GPR139 in neuropsychiatric behaviour and its potential as a therapeutic target in neuropsychiatric disorders.
