Glutamate receptor ionotropic, NMDA 2B

UniProtKB accession:  A7XY94

Grouped By:  Matching UniProtKB accession

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:18177891, PubMed:25008524, PubMed:28232581). Channel activation requires binding of the neurotransmitter L-glutamate to the GluN2 subunit, glycine binding to the GluN1 subunit, plus membrane depolarization to eliminate channel inhibition by Mg(2+) (PubMed:18177891, PubMed:25008524, PubMed:28232581). NMDARs mediate simultaneously the potasium efflux and the influx of calcium and sodium (By similarity). Each GluN2 subunit confers differential attributes to channel properties, including activation, deactivation and desensitization kinetics, pH sensitivity, Ca2(+) permeability, and binding to allosteric modulators (By similarity).
