Official Symbol: dop-2
Official Full Name: Dopamine receptor 2
Primary source: WormBase:WBGene00001053
Locus tag: CELE_K09G1.4
See related: AllianceGenome:WB:WBGene00001053
Gene type: protein coding
RefSeq status: REVIEWED
Organism: Caenorhabditis elegans (strain: Bristol N2)
Lineage: Eukaryota; Metazoa; Ecdysozoa; Nematoda; Chromadorea; Rhabditida; Rhabditina; Rhabditomorpha; Rhabditoidea; Rhabditidae; Peloderinae; Caenorhabditis
Summary: Enables dopamine neurotransmitter receptor activity, coupled via Gi/Go. Involved in several processes, including cellular response to amphetamine; male mating behavior; and regulation of locomotion involved in locomotory behavior. Predicted to be located in membrane and synapse. Predicted to be active in dendrite and plasma membrane. Is expressed in GLR; male-specific anatomical entity; and neurons. Used to study Parkinson's disease and nicotine dependence. Human ortholog(s) of this gene implicated in several diseases, including alcohol dependence; drug dependence (multiple); end stage renal disease; movement disease (multiple); and nicotine dependence. Orthologous to several human genes including DRD3 (dopamine receptor D3). [provided by Alliance of Genome Resources, Nov 2024]
