Drd3 - dopamine receptor D3

Enables dopamine neurotransmitter receptor activity, coupled via Gi/Go. Involved in behavioral response to cocaine and regulation of neurotransmitter uptake. Acts upstream of or within several processes, including regulation of blood pressure; regulation of dopamine receptor signaling pathway; and response to alkaloid. Located in plasma membrane. Is active in dopaminergic synapse. Is expressed in several structures, including brain; exocrine gland; genitourinary system; gut; and sensory organ. Used to study restless legs syndrome. Human ortholog(s) of this gene implicated in Parkinson's disease; essential tremor; essential tremor 1; and schizophrenia. Orthologous to human DRD3 (dopamine receptor D3).
