Component of NMDA receptor complexes that function as heterotetrameric, ligand-gated ion channels with high calcium permeability and voltage-dependent sensitivity to magnesium. Channel activation requires binding of the neurotransmitter glutamate to the epsilon subunit, glycine binding to the zeta subunit, plus membrane depolarization to eliminate channel inhibition by Mg(2+). Sensitivity to glutamate and channel kinetics depend on the subunit composition; channels containing GRIN1 and GRIN2A have lower sensitivity to glutamate and faster deactivation kinetics than channels formed by GRIN1 and GRIN2B (PubMed:28384476). Contributes to the slow phase of excitatory postsynaptic current, long-term synaptic potentiation, and learning (By similarity). {UniProtKB:P35436, PubMed:1350383, PubMed:16281028, PubMed:23625947, PubMed:24462099, PubMed:26679993, PubMed:27618671, PubMed:27916457, PubMed:28384476, PubMed:28468946, PubMed:28760974, PubMed:8428958}.

N-methyl-D-aspartate receptors are heteromeric protein complexes, and three families of NMDAR subunits have been identified: NR1, NR2 and NR3. The subunit composition determines the pharmacological and physiological properties of the NMDARs. NR2A is gradually increased in adult CNS but is absent in embryonic CNS. Electro- physiological data suggest that NR2A- containing NMDARs tend to be localized synaptically, whereas NR2B-containing receptors tend to be localized peri- synaptically or extrasynaptically. In the spinal cord, the predominant subunits of NMDARs include NR2A at synaptic sites and NR2B at extrasynaptic sites.
