Dopamine receptor D2, also known as D2R, is a protein that, in humans, is encoded by the DRD2 gene.n similar manner, older dopamine agonists used for Parkinson's disease such as bromocriptine and cabergoline are poorly selective for one dopamine receptor over another, and, although most of these agents do act as D 2 agonists, they affect other subtypes as well.
In the brain, dopamine functions as a neurotransmitter âa chemical released by nerve cells to send signals to other nerve cells. The brain includes several distinct dopamine systems, one of which plays a major role in reward-motivated behavior.opamine itself is used as precursor in the synthesis of the neurotransmitter norepinephrine and the hormone epinephrine. Dopamine is converted into norepinephrine by the enzyme dopamine Î²-hydroxylase (DBH), with O 2 and L-ascorbic acid as cofactors.
