Receptor for the hormone galanin. The activity of this receptor is mediated by G proteins that inhibit adenylate cyclase activity. Spinal cord, small intestine, Rin14B insulinoma cells and several brain regions, particularly ventral hippocampus, amygdala, supraoptic nucleus, hypothalamus, thalamus, lateral parabrachial nucleus and locus coeruleus. Three cysteine residues are found in the C-terminus, at least one of which may be palmitoylated. Belongs to the G-protein coupled receptor 1 family.
