GPR139

GPR139, also known as G protein-coupled receptor 139, is a protein that belongs to the G protein-coupled receptor (GPCR) superfamily. It is primarily expressed in the central nervous system, particularly in regions associated with the regulation of neurotransmitter systems and neuronal activity. Although the specific functions of GPR139 are still being elucidated, it is believed to play a role in modulating neurotransmission, particularly in the regulation of dopamine and glutamate signaling. Studies have suggested that GPR139 may function as an inhibitory receptor, as its activation leads to decreased cAMP (cyclic adenosine monophosphate) levels and reduced neuronal excitability. Moreover, GPR139 has been implicated...
