Data Sheet
Background: MT1 (Melatonin receptor 1A, previously Mel 1A or ML 1A) is a receptor for melatonin. Melatonin is synthesized mainly in the pineal gland but is also made by other organs, such as the retina and the stomach. It is essential to the regulation of the mammalian circadian system and reproductive function. Melatonin receptor agonists may also be useful as a supplement to classical antidepressant treatments.
Application: Functional assays
