Galanin
A neuropeptide of 29-30 amino acids depending on the species. Galanin is widely distributed throughout the BRAIN; SPINAL CORD; and INTESTINES. There are various subtypes of GALANIN RECEPTORS implicating roles of galanin in regulating FOOD INTAKE; pain perception; memory; and other neuroendocrine functions.
Receptors, Galanin
A family of G-protein-coupled receptors that are specific for GALANIN and galanin peptides. They are generally considered to be coupled to the GI, INHIBITORY G-PROTEIN to meditate the neurological effects of galanin. Several subtypes of galanin receptors occur with differing specificities for the full length galanin, galanin peptide fragments, and galanin-like peptide.
Receptor, Galanin, Type 2
A galanin receptor subtype with broad specificity for full length GALANIN, galanin peptide fragments and GALANIN-LIKE PEPTIDE.
Receptor, Galanin, Type 1
Receptor, Galanin, Type 3
A galanin receptor subtype with high affinity for GALANIN-LIKE PEPTIDE and low affinity for full length GALANIN and galanin peptide fragments.
Receptors, Gastrointestinal Hormone
Galanin-Like Peptide
Receptors, Neuropeptide
Cell surface receptors that bind specific neuropeptides with high affinity and trigger intracellular changes influencing the behavior of cells. Many neuropeptides are also hormones outside of the nervous system.
Neuropeptides
Peptides released by NEURONS as intercellular messengers. Many neuropeptides are also hormones released by non-neuronal cells.
