Mgi Type | protein coding gene |
description | FUNCTION: Automated description from the Alliance of Genome Resources (Release 8.0.0) Enables G protein-coupled receptor activity; dopamine binding activity; and dopamine neurotransmitter receptor activity, coupled via Gi/Go. Involved in several processes, including hyaloid vascular plexus regression; negative regulation of innate immune response; and presynaptic modulation of chemical synaptic transmission. Acts upstream of or within several processes, including G protein-coupled dopamine receptor signaling pathway; modulation of chemical synaptic transmission; and nervous system development. Located in axon and dendrite. Is active in several cellular components, including GABA-ergic synapse; dopaminergic synapse; and synaptic membrane. Is expressed in several structures, including alimentary system; genitourinary system; nervous system; respiratory system; and sensory organ. Used to study Parkinson's disease and primary hyperaldosteronism. Human ortholog(s) of this gene implicated in several diseases, including alcohol dependence; drug dependence (multiple); end stage renal disease; nicotine dependence; and type 2 diabetes mellitus. Orthologous to human DRD2 (dopamine receptor D2). 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] |
