DRD2
DRD2, or Dopamine Receptor D2, is a G protein-coupled receptor that mediates the effects of dopamine in the central nervous system. It plays a crucial role in regulating motor control, motivation, reward, and cognitive functions. DRD2 is a primary target for antipsychotic medications and is implicated in various neurological and psychiatric disorders, including schizophrenia, Parkinson's disease, and addiction. Its signaling pathways are vital for understanding dopaminergic neurotransmission and developing targeted therapies.
