dopamine receptor

Any of at least six receptors that bind dopamine in the brain. They influence body movements and emotional states. The dopamine receptors are designated D1, D2a, D2b, D3, D4, and D5. Each has an identifiably different function. The D2a receptor, for example, has a strong affinity for antipsychotic drugs, such as haloperidol.
