Galanin

Galanin is a neuropeptide which is found in the central and peripheral nervous system. It is involved in a number of physiological processes such as regulation of food intake, metabolism and reproduction, regulation of neurotransmitter and hormone release, nociception, intestinal motility and secretion, and more recently in nervous system development and response to injury. The wide diversity of actions is mediated by several galanin receptor subtypes.
