Grin1 Gene Summary [Mouse]
Enables several functions, including calmodulin binding activity; cation binding activity; and monoatomic ion channel activity. Involved in calcium ion transmembrane transport; propylene metabolic process; and regulation of synaptic plasticity. Acts upstream of or within several processes, including chemical synaptic transmission; learning or memory; and regulation of neuron projection development. Located in several cellular components, including postsynaptic density; postsynaptic membrane; and synaptic vesicle membrane. Part of NMDA selective glutamate receptor complex. Is active in glutamatergic synapse and postsynaptic density membrane. Is expressed in several structures, including alimentary system; cardiovascular system; central nervous system; sensory organ; and skeleton. Used to study autism spectrum disorder and schizophrenia. Human ortholog(s) of this gene implicated in alcohol use disorder; autosomal dominant intellectual developmental disorder 8; cerebral infarction; and developmental and epileptic encephalopathy 101. Orthologous to human GRIN1 (glutamate ionotropic receptor NMDA 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 mouse Grin1 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
