Protein name Melatonin receptor type 1B (Mel-1B-R) (Mel1b receptor)
Protein function High affinity receptor for melatonin. Likely to mediate the reproductive and circadian actions of melatonin. The activity of this receptor is mediated by pertussis toxin sensitive G proteins that inhibit adenylate cyclase activity.
