MGI Phenotype FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] This gene encodes the D2 subtype of the dopamine receptor. This G-protein coupled receptor inhibits adenylyl cyclase activity. A missense mutation in this gene causes myoclonus dystonia; other mutations have been associated with schizophrenia. Alternative splicing of this gene results in two transcript variants encoding different isoforms. A third variant has been described, but it has not been determined whether this form is normal or due to aberrant splicing. [provided by RefSeq, Jul 2008]
PHENOTYPE: Homozygous null mice show Parkinson's disease like symptoms, including akinetic and bradykinetic behavior. Mice lacking only the long isoform are hypoactive and exhibit increased sterotypic behavior in response to dopamine agonists. [provided by MGI curators]
