Dopamine D2 R/DRD2: Proteins and Enzymes

DRD2 encodes the D2 subtype of the dopamine receptor that inhibits adenylyl cyclase activity. Alternative splicing of this G protein-coupled receptor results in two transcript variants encoding different isoforms. DRD2 plays a major role in the neural circuitry that mediates behavioral control, an ability that is essential for adaptive responding and is compromised in a variety of common neuropsychiatric disorders.
