Galanin receptors (provisional nomenclature as recommended by NC-IUPHAR [8]) are activated by the endogenous peptides galanin (GAL, P22466) and galanin-like peptide (GALP, Q9UBC7). Human galanin (GAL, P22466) is a 30 amino-acid non-amidated peptide [6]; in other species, it is 29 amino acids long and C-terminally amidated. Amino acids 1-14 of galanin are highly conserved in mammals, birds, reptiles, amphibia and fish. Shorter peptide species (e.g. human galanin-1-19 [3] and porcine galanin-5-29 [23]) and N-terminally extended forms (e.g. N-terminally seven and nine residue elongated forms of porcine galanin [4,23]) have been reported. More recently, the newly-identified peptide, spexin (SPX), has been reported to activate human GAL2 and GAL3 (but not GAL1) receptors in heterologous expression systems; and to alter GAL2/3 receptor-related behaviours in animals [10].
