Melatonin receptor type 1A is a protein that in humans is encoded by the MTNR1A gene.^[1]^[2]

Function

This gene encodes the MT₁ protein, one of two high-affinity forms of a receptor for melatonin, the primary hormone secreted by the pineal gland. This receptor is a G protein-coupled, 7-transmembrane receptor that is responsible for melatonin effects on mammalian circadian rhythm and reproductive alterations affected by day length. The receptor is an integral membrane protein that is readily detectable and localized to two specific regions of the brain. The hypothalamic suprachiasmatic nucleus appears to be involved in circadian rhythm while the hypophysial pars tuberalis may be responsible for the reproductive effects of melatonin.^[2]

Ligands

Melatonin – full agonist
Afobazole – agonist

Melatonin inhibits growth and invasive capacity of colon cancer cells in vitro through its membrane (MT1 and MT2) and/or nuclear receptors (RORα). Previous studies showed that this indoleamine is present in both the normal and colon cancer at similar levels. Therefore, we analyzed MT1, MT2, and ROR
