GPR50 Antibody / Melatonin-related receptor

G protein-coupled receptor 50 is a protein which in humans is encoded by the GPR50 gene. This gene product belongs to the G-protein coupled receptor 1 family. Even though this protein shares similarity with the melatonin receptors, it does not bind melatonin, however, it inhibits melatonin receptor 1A function through heterodimerization. Polymorphic variants of this gene have been associated with bipolar affective disorder in women.
