Grin3a Gene Summary [Rat]
Enables carboxylic acid binding activity; glutamate-gated receptor activity; and protein phosphatase 2A binding activity. Contributes to NMDA glutamate receptor activity. Involved in several processes, including ionotropic glutamate receptor signaling pathway; monoatomic cation transport; and negative regulation of dendritic spine development. Located in cytoplasm and postsynaptic membrane. Part of NMDA selective glutamate receptor complex. Is active in glutamatergic synapse and postsynaptic density membrane. Orthologous to human GRIN3A (glutamate ionotropic receptor NMDA type subunit 3A). [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 Grin3a often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
