What is the official name of the DRD3 gene?
The official name of this gene is “dopamine receptor D3.”
DRD3 is the gene's official symbol. The DRD3 gene is also known by other names, listed below.
Read more about gene names and symbols on the About page.
What is the normal function of the DRD3 gene?
The DRD3 gene provides instructions for making a protein called dopamine receptor D3, which is found in the brain. This protein responds to the chemical messenger (neurotransmitter) dopamine to trigger signals within the nervous system, including signals involved in producing physical movement.
Does the DRD3 gene share characteristics with other genes?
The DRD3 gene belongs to a family of genes called GPCR (G protein-coupled receptors).
A gene family is a group of genes that share important characteristics. Classifying individual genes into families helps researchers describe how genes are related to each other. For more information, see What are gene families? in the Handbook.
Where is the DRD3 gene located?
Cytogenetic Location: 3q13.3
Molecular Location on chromosome 3: base pairs 114,128,709 to 114,199,406
The DRD3 gene is located on the long (q) arm of chromosome 3 at position 13.3.
More precisely, the DRD3 gene is located from base pair 114,128,709 to base pair 114,199,406 on chromosome 3.
