Melatonin receptors are G protein-coupled receptors (GPCR) which bind melatonin. [1] Three types of melatonin receptors have been cloned.The MT 1 (or Mel 1A or MTNR1A) and MT 2 (or Mel 1B or MTNR1B) receptor subtypes are present in humans and other mammals, [2] while an additional melatonin receptor subtype MT 3 (or Mel 1C or MTNR1C) has been identified in amphibia and birds.

Melatonin, an indoleamine, is a natural compound produced by various organisms, including bacteria and eukaryotes. [1] Its discovery in 1958 by Aaron B. Lerner and colleagues stemmed from the isolation of a substance from the pineal gland of cows that could induce skin lightening in common frogs.
The melatonin receptors are G protein-coupled receptors and are expressed in various tissues of the body. There are two subtypes of the receptor in humans, melatonin receptor 1 (MT 1) and melatonin receptor 2 (MT 2). [2] Melatonin and melatonin receptor agonists, on market or in clinical trials, all bind to and activate both receptor types. [1]
The pineal gland (also known as the pineal body [1] or epiphysis cerebri) is a small endocrine gland in the brain of most vertebrates.It produces melatonin, a serotonin-derived hormone, which modulates sleep patterns following the diurnal cycles. [2]

Melatonin is thought to activate melatonin receptors in the suprachiasmatic nucleus of the hypothalamus to regulate the circadian clock and sleep–wake cycles. [21] When used several hours before sleep according to the phase response curve for melatonin in humans, small amounts (0.3 mg [ 56 ] ) of melatonin shift the circadian clock earlier ...
Other drugs act by binding to a receptor and mimicking the normal neurotransmitter. Such drugs are called receptor agonists. An example of a receptor agonist is morphine, an opiate that mimics effects of the endogenous neurotransmitter β-endorphin to relieve pain. Other drugs interfere with the deactivation of a neurotransmitter after it has ...
