Dopamine D2 receptor

Dopamine D2 receptor

The Dopamine D2 receptor (pronounced doh-puh-meen dee-two ree-sep-tor) is a type of protein that is encoded by the DRD2 gene in humans. It is a subtype of the Dopamine receptors, which are integral membrane proteins that stimulate a cellular response upon binding with Dopamine, a type of Neurotransmitter.

Etymology

The term "Dopamine D2 receptor" is derived from the name of the neurotransmitter, dopamine, and the classification of the receptor, D2. Dopamine is derived from the Greek words "dopa", which means "gift", and "amine", a type of organic compound. The D2 classification is a subtype of dopamine receptors, indicating its unique structure and function.

Function

The Dopamine D2 receptor primarily inhibits the production of cAMP by inhibiting the enzyme Adenylyl cyclase. It also plays a crucial role in the functioning of the Central nervous system, particularly in the Striatum, where it is involved in the regulation of reward and reinforcement, motor control, and the release of various neurotransmitters.
