Summary: Enables NMDA glutamate receptor activity and calcium channel activity. Involved in regulation of synaptic plasticity. Acts upstream of or within several processes, including excitatory postsynaptic potential; learning or memory; and long-term synaptic potentiation. Located in several cellular components, including glutamatergic synapse; synaptic membrane; and synaptic vesicle. Is integral component of postsynaptic density membrane. Part of NMDA selective glutamate receptor complex. Is expressed in several structures, including central nervous system; eye; hindlimb phalanx; intestine; and limb mesenchyme. Human ortholog(s) of this gene implicated in Huntington's disease; bipolar disorder; and schizophrenia. Orthologous to human GRIN2A (glutamate ionotropic receptor NMDA type subunit 2A).

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
