Protein Structure

UniProt Annotation

Function

Dopamine receptor whose activity is mediated by G proteins which inhibit adenylyl cyclase. Promotes cell proliferation. {ECO:0000269PubMed:19520868}.

Subcellular Localization

Cell membrane {ECO:0000269PubMed:19520868}; Multi-pass membrane protein {ECO:0000269PubMed:19520868}. Note=Both membrane-bound and scattered in the cytoplasm during basal conditions. Receptor stimulation results in the rapid internalization and sequestration of the receptors at the perinuclear area (5 and 15 minutes), followed by the dispersal of the receptors to the membrane (30 minutes). DRD3 and GRK4 co- localize in lipid rafts of renal proximal tubule cells.

Disease Associations

Tremor, hereditary essential 1 (ETM1) [MIM:190300]: A common movement disorder mainly characterized by postural tremor of the arms. Head, legs, trunk, voice, jaw, and facial muscles also may be involved. The condition can be aggravated by emotions, hunger, fatigue and temperature extremes, and may cause a functional disability or even incapacitation. Inheritance is autosomal dominant. {ECO:0000269PubMed:16650084, ECO:0000269PubMed:16809426}. Note=Disease susceptibility is associated with variations affecting the gene represented in this entry.

Tissue Specificity

Brain.
