Dopamine receptors are "cell-surface proteins that bind dopamine with high affinity and trigger intracellular changes influencing the behavior of cells."[1]
Classification
D1-like receptors
These receptors stimulate adenylate cyclase.[2]
D1 receptors
D5 receptors
D2-like receptors
These receptors inhibit adenylate cyclase.[3]
Dopamine D2 receptors
Agonists, such as metoclopramide, are used as antiemetics.
Antagonists, such as risperidone and haloperidol, are used to treat schizophrenia.[4]
Blockade of the D2 receptors, which may be predisposed by genetic polymorphisms of the allele, may cause neuroleptic malignant syndrome.[5]
D3 receptors
Agonists of D3, especially nonergot agonists such as pramipexole and ropinirole, may be used to treat Parkinonism and restless legs syndrome.[6]
D4 receptors
Novelty seeing personality trait may be related to polymorphisms in the dopamine receptor D4 that affects dopamine activity in the tuberoinfundibular dopaminergic system.[7]
