GPR88 Receptor Antibodies
GPR88 (G Protein-Coupled Receptor 88) is an orphan GPCR with no confirmed endogenous ligand, but it is known to play a key role in modulating neurotransmission and behavioral regulation. It primarily signals through Gi/o proteins, inhibiting intracellular cAMP production. GPR88 is highly and selectively expressed in the central nervous system, particularly in the striatum, nucleus accumbens, and cortex—regions involved in motor control, reward processing, and emotional regulation. GPR88 is considered a promising pharmacological target for neuropsychiatric and neurological disorders, including schizophrenia, Parkinson’s disease, addiction, and depression. Preclinical studies show that modulating GPR88 activity can influence dopaminergic and glutamatergic signaling. For more information on GPR88 pharmacology please refer to the IUPHAR database.
