Data Sheet

Background: GPR52 is a class-A orphan G-protein-coupled receptor that can be found in human and mice, and is highly expressed in the brain and represents a promising therapeutic target for the treatment of Huntington’s disease and several psychiatric disorders. Once activated by antipsychotics reserpine, an increase of intracellular cAMP and its internalization is resulted. Members of this protein family contain transmembrane domain and may play a role in locomotor activity through modulation of dopamine, NMDA and ADORA2A-induced locomotor activity. They represent a promising therapeutic target for the treatment of Huntington’s disease and several psychiatric disorders.

Application: Functional assays
