Dopamine receptor D3 is a protein that in humans is encoded by the DRD3 gene.[5][6]

This gene encodes the D3 subtype of the

drug addiction, and Parkinson's disease.[7] Alternative splicing of this gene results in multiple transcript variants that would encode different isoforms, although some variants may be subject to nonsense-mediated decay (NMD).[6]

Function

Alpha-synuclein (α-Syn) aggregation via Lewy bodies inclusion, a pathogenic signature exclusively present in PD patients, is decreased by D3 agonists while DA content is elevated by inhibiting DA reuptake and breakdown. The regulation of α-Syn aggregation and clearance enhances brain-derived neurotrophic factor (BDNF) secretion, which ultimately ameliorates neuroinflammation and oxidative stress while promoting neurogenesis and interacting with other DA receptors.[8][9]

D3 agonists like 7-OH-DPAT, pramipexole, and rotigotine, among others, display antidepressant effects in rodent models of depression.[10][11] Apomorphine has the ability to help PD patients with their cognition awareness.[12] In addition to having antidepressant properties such as regulating the depression-like behaviors and depression development, pramipexole has the capability to prevent and slow down cell apoptosis as well as to restore damaged neural networks and connections while rotigotine help PD patients to attenuates hyperpyrexia syndrome and schizophrenia.[13][14]

Animal studies

D3 agonists have been shown to disrupt prepulse inhibition of startle (PPI), a cross-species measure that recapitulates deficits in sensorimotor gating in neuropsychiatric disorders such as schizophrenia.[15][16][17] In contrast, D3-preferring antagonists have antipsychotic-like profiles in measures of PPI in rats.[18]

Interactions

Dopamine receptor D3 has been shown to

interact with CLIC6[35] and EPB41L1.[36]

DRD3 Ser9Gly polymorphism(rs6280), which is a single nucleotide polymorphism (SNP) with variant base C/T is linked to variation in PD such as depression severity, impulse control disorders, behavioral addiction and aberrant decision-making.[37][38][39][40]
