Processes
  • negative regulation of insulin secretion
  • camera-type eye development
  • mating behavior
  • positive regulation of cGMP biosynthetic process
  • cell surface receptor signaling pathway
  • circadian rhythm

General FunctionOrganic cyclic compound binding
Specific FunctionHigh affinity receptor for melatonin. Likely to mediates the reproductive and circadian actions of melatonin. The activity of this receptor is mediated by pertussis toxin sensitive G proteins that inhibit adenylate cyclase activity.
