Summaries for DRD2 Gene

Entrez Gene Summary for DRD2 Gene

  • 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]

GeneCards Summary for DRD2 Gene

DRD2 (Dopamine Receptor D2) is a Protein Coding gene. Diseases associated with DRD2 include Dystonia-11, Myoclonic and Cocaine Dependence. Among its related pathways are Peptide ligand-binding receptors and cAMP signaling pathway. GO annotations related to this gene include G-protein coupled receptor activity and identical protein binding. An important paralog of this gene is HTR1F.

UniProtKB/Swiss-Prot for DRD2 Gene

  • Dopamine receptor whose activity is mediated by G proteins which inhibit adenylyl cyclase.

Tocris Summary for DRD2 Gene

  • D2 receptors are members of the dopamine receptor G-protein-coupled receptor family that also includes D1, D3, D4 and D5. They are involved in the modulation of locomotion, reward, reinforcement and memory and learning.

Genetic variations in DRD2 may determine the genetic susceptibility to alcoholism [MIM:103780]. Genetic variations in DRD2 might be a protective factor against the development of withdrawal symptoms but might also be a risk factor in a highly burdened subgroup of alcoholics with a paternal and grandpaternal history of alcoholism and might contribute to suicide risk in alcoholics.
