Galanin receptors are a family of G protein-coupled receptors (GPCRs) comprised of three different receptor subtypes: GAL1, GAL2, and GAL3. Galanin receptors are found all throughout the endocrine, peripheral, and central nervous systems, regulating a variety of biological functions such as arousal, sleep, cognition, reproduction, and metabolic and osmotic homeostasis. Galanin receptor agonists have applications in anti-seizure treatments, while antagonists have potential applications in treatments for anxiety and depression.
