« Hide More detailed introduction

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 [20]) and N-terminally extended forms (e.g. N-terminally seven and nine residue elongated forms of porcine galanin [4,20]) have been reported.
