UniProtKB description:  Component of N-methyl-D-aspartate (NMDA) receptors (NMDARs) that function as heterotetrameric, ligand-gated cation channels with high calcium permeability and voltage-dependent block by Mg(2+) (PubMed:1350383, PubMed:1388270, PubMed:1834949, PubMed:8428958). NMDARs participate in synaptic plasticity for learning and memory formation by contributing to the long-term potentiation (LTP) (By similarity). Channel activation requires binding of the neurotransmitter L-glutamate to the GluN2 subunit, glycine or D-serine binding to the GluN1 subunit, plus membrane depolarization to eliminate channel inhibition by Mg(2+) (PubMed:11823786, PubMed:1350383, PubMed:1388270, PubMed:15996549, PubMed:18177891, PubMed:1834949, PubMed:24876489, PubMed:27135925, PubMed:27618671, PubMed:28384476, PubMed:28468946, PubMed:8428958). NMDARs mediate simultaneously the potasium efflux and the influx of calcium and sodium (By similarity). Each GluN2 or GluN3 subunit confers differential attributes to channel properties, including activation, deactivation and desensitization kinetics, pH sensitivity, Ca2(+) permeability, and binding to allosteric modulators (PubMed:10436042, PubMed:11160393, PubMed:11929923, PubMed:28384476, PubMed:9463421). Forms excitatory glycinergic receptor complexes with GluN3 alone which are activated by glycine binding to the GluN1 and GluN3 subunits (PubMed:11823786, PubMed:11929923, PubMed:12391275).
