GPR26 Receptor Antibodies
GPR26 (G Protein-Coupled Receptor 26) is an orphan GPCR with constitutive activity, primarily coupling to Gs proteins to increase intracellular cAMP levels. Its endogenous ligand has not been identified, but it is thought to play roles in central nervous system functions. GPR26 is predominantly expressed in the brain, especially in regions such as the cerebral cortex, hippocampus, and amygdala, which are involved in mood regulation, learning, and memory. This brain-specific expression pattern points to a potential role in neuropsychiatric functions. GPR26 is being investigated as a potential pharmacological target in neurological and psychiatric disorders, including anxiety, depression, and epilepsy. Preclinical studies have shown that modulation of GPR26 expression or activity can influence mood and seizure susceptibility. While no selective ligands or drugs are currently available, its expression profile and constitutive signaling make it a candidate for future therapeutic exploration in CNS-related diseases.
