Gria1 Gene Summary [Rat]

Enables several functions, including enzyme binding activity; signaling receptor binding activity; and transmitter-gated monoatomic ion channel activity. Involved in several processes, including central nervous system development; learning or memory; and modulation of chemical synaptic transmission. Located in several cellular components, including dendrite; endosome membrane; and neuronal cell body membrane. Part of AMPA glutamate receptor complex. Is active in glutamatergic synapse; postsynaptic density membrane; and presynaptic active zone membrane. Used to study cocaine dependence; hyperhomocysteinemia; morphine dependence; and withdrawal disorder. Biomarker of several diseases, including alcohol use disorder; amphetamine abuse; brain disease (multiple); cocaine abuse; and drug dependence (multiple). Human ortholog(s) of this gene implicated in autosomal dominant intellectual developmental disorder 67; autosomal recessive intellectual developmental disorder 76; and epilepsy. Orthologous to human GRIA1 (glutamate ionotropic receptor AMPA type subunit 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 Gria1 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
