Background: The diverse physiological effects of Galanin, a biologically active neuropeptide, are mediated through cell surface G protein-coupled receptors. There are three galanin receptor subtypes, GALR1, GALR2 and GALR3 that have been widely used and Recently, a new GPCR, GalRL4 have been identified, termed as GPR151, which shows 41–43% similarity at the amino-acid level with the galanin-receptor subfamily. Galanin, widely distributed in the central and peripheral nervous systems and the endocrine systems, binds to galanin receptors to induce several regulatory functions in neuronal cells, including neuroregeneration, control of endocrine and exocrine secretions, and modulation of sensory and behavioral functions. Galanin agonists have been shown to have therapeutic application in treatment of chronic pain; galanin antagonists have therapeutic potential in treatment of Alzheimer’s disease, depression, and feeding disorders.
