Drd4 Gene Summary [Rat]
Enables dopamine binding activity; dopamine neurotransmitter receptor activity, coupled via Gi/Go; and heterocyclic compound binding activity. Involved in several processes, including learning or memory; modulation of chemical synaptic transmission; and regulation of signal transduction. Located in several cellular components, including cytoplasmic side of plasma membrane; dendrite; and perikaryon. Is active in GABA-ergic synapse; glutamatergic synapse; and synaptic membrane. Biomarker of attention deficit hyperactivity disorder and obesity. Human ortholog(s) of this gene implicated in several diseases, including Gilles de la Tourette syndrome; antisocial personality disorder; attention deficit hyperactivity disorder; conduct disorder; and substance abuse (multiple). Orthologous to human DRD4 (dopamine receptor D4). [provided by Alliance of Genome Resources, Jul 2025]

Protein Domains
A protein domain is a distinct structural or functional region within a protein that can evolve, function, and exist independently of the rest of the protein chain. These domains in rat Drd4 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
