[[http://www.uniprot.org/uniprot/NMDE2_RAT NMDE2_RAT]] NMDA receptor subtype of glutamate-gated ion channels with high calcium permeability and voltage-dependent sensitivity to magnesium. Mediated by glycine. In concert with DAPK1 at extrasynaptic sites, acts as a central mediator for stroke damage. Its phosphorylation at Ser-1303 by DAPK1 enhances synaptic NMDA receptor channel activity inducing injurious Ca2+ influx through them, resulting in an irreversible neuronal death (By similarity).  
[https://www.uniprot.org/uniprot/NMDZ1_XENLA NMDZ1_XENLA] 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+) (PubMed:16214956, PubMed:19524674, PubMed:21677647, PubMed:25008524, PubMed:26912815, PubMed:27135925, Ref.11, PubMed:28232581). Sensitivity to glutamate and channel kinetics depend on the subunit composition (Probable).<ref>PMID:16214956</ref> <ref>PMID:19524674</ref> <ref>PMID:21677647</ref> <ref>PMID:25008524</ref> <ref>PMID:26912815</ref> <ref>PMID:27135925</ref> <ref>PMID:28232581</ref> [PDB:5IOV]
