This article reviews the advances made in the molecular biology of dopamine receptors, and discusses the relationship between these receptors and neuropsychiatric disorders. Until recently, it was accepted that dopamine affects its target cells in the brain via interaction with only two receptor subtypes, D1 and D2. However, molecular biological studies have confirmed the existence of additional dopamine receptors, D1, D2, D3, D4 and D5, which have been cloned, characterized and classified in two subgroups, D1 (D1 and D5) and D2 (D2, D3 and D4), according to their gene organization,pharmacology and signalling systems. The amino acid sequences of all these receptors reveals that they belong to a large superfamily, that of receptors with seven transmembrane domains and coupled to their intracellular transduction system by a G protein.
