7DB6 - PubMed Abstract: 
Melatonin receptors (MT 1 and MT 2 ) transduce inhibitory signaling by melatonin (N-acetyl-5-methoxytryptamine), which is associated with sleep induction and circadian rhythm modulation. Although recently reported crystal structures of ligand-bound MT 1 and MT 2 elucidated the basis of ligand entry and recognition, the ligand-induced MT 1 rearrangement leading to G i -coupling remains unclear ...
