Oprd1 Gene Summary [Rat]
Enables G protein-coupled enkephalin receptor activity and receptor serine/threonine kinase binding activity. Involved in several processes, including eating behavior; response to ethanol; and response to nicotine. Located in several cellular components, including axon terminus; dendrite membrane; and postsynaptic membrane. Is active in secretory vesicle; spine apparatus; and synaptic membrane. Used to study alcohol use disorder and myocardial infarction. Biomarker of alcohol use disorder. Human ortholog(s) of this gene implicated in alcohol dependence; alcohol use disorder; drug dependence (multiple); opioid abuse; and withdrawal disorder. Orthologous to human OPRD1 (opioid receptor delta 1). [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 Oprd1 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
