Function

NMDZ1_MOUSE 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:12008020, PubMed:12860921, PubMed:14602821, PubMed:1532151, PubMed:8060614, PubMed:9049108). 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:12008020, PubMed:1532151, PubMed:7790891, PubMed:8060614). NMDARs mediate simultaneously the potasium efflux and the influx of calcium and sodium (PubMed:12860921). 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:12008020, PubMed:14602821).[UniProtKB:Q05586]^{[1] [2] [3] [4] [5] [6] [7]}
