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.

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]

Ramelteon is a melatonin receptor agonist with both high affinity for melatonin MT 1 and MT 2 receptors and selectivity over the non-human MT 3 receptor. Ramelteon demonstrates full agonist activity in vitro in cells expressing human MT 1 or MT 2 receptors, and high selectivity for human MT 1 and MT 2 receptors compared to the non-human MT 3 ...
Agomelatine acts as a highly potent and selective melatonin MT 1 and MT 2 receptor agonist (K i = 0.1 nM and 0.12 nM, respectively) and also as a relatively weak serotonin 5-HT 2B and 5-HT 2C receptor antagonist (K i = 660 nM and 631 nM, respectively; ~6,000-fold lower than for the melatonin receptors).

The interactions of muscarinic toxins studied using tritiated 3 H-N-methyl scopolamine (NMS) with human muscarinic receptor subtypes m1, m2, m3 and m4 has shown that MT2 and the related MT1 toxin are specific for M1 (Ki=630 nM) [2] and M4 (Ki=1900 nM) [2] receptors, but have little effect on binding to M2 and M3 receptors.
