FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] This gene encodes the D4 subtype of the dopamine receptor. The D4 subtype is a G-protein coupled receptor which inhibits adenylyl cyclase. It is a target for drugs which treat schizophrenia and Parkinson disease. Mutations in this gene have been associated with various behavioral phenotypes, including autonomic nervous system dysfunction, attention deficit/hyperactivity disorder, and the personality trait of novelty seeking. This gene contains a polymorphic number (2-10 copies) of tandem 48 nt repeats; the sequence shown contains four repeats. [provided by RefSeq, Jul 2008]
PHENOTYPE: Homozygous mutants are less active in open field tests and have reduced responses to novelty. However, mice exhibit locomotor supersensitivity to ethanol, cocaine, and methamphetamine. [provided by MGI curators]
