Galanin is a neuropeptide, consisting of 29-30 amino acid residues, involved in the regulation of cognition, mood, feeding, seizure activity and pain. Galanin exerts its action via three known Galanin receptors, the Galanin receptor type 1 (GALR1), Galanin receptor type 2 (GALR2) and Galanin receptor type 3 (GALR3). The Galanin receptors belong to the G-protein-coupled receptor superfamily.
