产品描述： This gene encodes 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.
