Mammalian MT1 melatonin receptor, Gi-coupled GPCR.
The mammalian MT1 melatonin receptor is a G protein-coupled receptor (GPCR) primarily coupled to the Gi/o protein family. This receptor plays a crucial role in regulating circadian rhythms and sleep-wake cycles by responding to melatonin, a hormone produced by the pineal gland. The MT1 receptor has a seven-transmembrane domain structure characteristic of GPCRs and is involved in inhibiting adenylate cyclase activity, leading to decreased levels of cAMP. It also participates in other signaling pathways, including the activation of phospholipase C and the regulation of intracellular calcium levels. Structural studies of MT1 reveal unique features such as a "lid-like" structure in the extracellular loop 2 (ECL2) that influences ligand binding and selectivity. This part is essential for projects involving the study of circadian biology, sleep regulation, and the pharmacological targeting of melatonin receptors.
