Melatonin is a neurohormone synthesized and secreted mainly during the dark period of the circadian cycle by the pineal gland. It has already been proved to be involved in a number of chronobiological processes, most of them being mediated by its membranar receptors MT 1 and MT 2. Both are...
Beside their differences in tissue distribution, mt1 and MT2 are present in a wide range of vertebrates, including chicken, frog and fish, while Xenopus melatonin receptor is absent in mammals. Melatonin receptors are capable of regulating a number of second messenger systems through the ...
The structure of MT2 is described in an accompanying paper14. Although the MT1 and 5-HT receptors have similar endogenous ligands, and agomelatine acts on both receptors, the receptors differ markedly in the structure and composition of their ligand pockets; in MT1, access to the ligand pocket...

Melatonin receptors (MT1 and MT2) transduce inhibitory signaling by melatonin (N-acetyl-5-methoxytryptamine), which is associated with sleep induction and circadian rhythm modulation. Although recently reported crystal structures of ligand-bound MT1 and MT2 elucidated the basis of ligand entry and reco...
It exerts effect by activating two types of melatonin receptors, type 1A (MT1) and 1B (MT2). These are G-protein-coupled receptors, predominantly located in the central nervous system. MT1/MT2 agonists could be a useful treatment approach according to all three prevalent theories of the ...
The matrix metalloproteinase (MMP) family of proteases are a group of zinc-dependent enzymes that target extracellular proteins, including growth factors, cell surface receptors, adhesion molecules, and other proteases (1). Matrix metalloproteinases can be broadly categorized based on function and cellu...
The mRNA levels of MT1 and MT2 receptors were analyzed with sequencing data. The expression and localization of the MT1 receptor with melatonin treatment were investigated by immunoblotting, immunofluorescence and confocal microscopy assays. Endocytic deubiquitylases were screened to identify MT1 associati...
1 It regulates a wide variety of physiological functions in the body, such as sleep, biological rhythms, immune responses, retinal physiology, pain, and neuroendocrine processes.2 These effects are mediated through the activation of MT1 and MT2 receptors, which are members of the G protein-...
