Biological Information

Background Information:

Melatonin receptors belong to the superfamily of G protein-coupled seven transmembrane proteins. G-protein-coupled receptors constitute one of the major signal transduction systems in eukaryotic cells. Coding sequences for these receptors, in those regions believed to contribute to the agonist-antagonist binding site, are strongly conserved across mammalian species. Melatonin, present primarily in the central nervous system, is released following a circadian rhythm with high levels at night.
