Protein attributes

Sequence length	353 AA.
Sequence status	Complete.
Protein existence	Evidence at transcript level

General annotation (Comments)

Function	High affinity receptor for melatonin. Likely to mediates 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 By similarity.
Subcellular location	Cell membrane; Multi-pass membrane protein.
Sequence similarities	Belongs to the G-protein coupled receptor 1 family.
