Biological Information
Background Information:
Dopamine receptors belong to the superfamily of G protein-coupled seven transmembrane proteins. G-protein-coupled receptors constitute one of the major signal transduction systems in eukaryotic cells. Coding sequences for these receptors, in those regions believed to contribute to the agonist-antagonist binding site, are strongly conserved across mammalian species. Various members of the dopamine receptor family are generally classified as either ‘D1-like’ or ‘D2-like’. D2-like receptors comprise the D2, D3 and D4 receptors, which inhibit activation of adenylate cyclases via coupling to G1/G0 protein.

Clinical Relevance
Therapeutic Area:
CNS/Addiction/Pain
Adverse / Beneficial Action:
Dopamine D4 receptor antagonism may be useful in the treatment of psychosis, possibly without causing tardive dyskineasia and hyperprolactineamia; receptor antagonism has also been reported to reduce novelty seeking. No major pharmacological differences have been reported for the most common variants of this receptor (D4.2, D4.4 and D4.7).
