The D<sub>2</sub>-like receptors are a subfamily of dopamine receptors that bind the endogenous neurotransmitter dopamine. The D<sub>2</sub>-like subfamily consists of three G-protein coupled receptors that are coupled to G<sub>i</sub>/G<sub>o</sub> and mediate inhibitory neurotransmission, of which include D<sub>2</sub>, D<sub>3</sub>, and D<sub>4</sub>. For more information, please see the respective main articles of the individual subtypes.
