[[http://www.uniprot.org/uniprot/NMDE1_RAT NMDE1_RAT]] NMDA receptor subtype of glutamate-gated ion channels possesses high calcium permeability and voltage-dependent sensitivity to magnesium. Activation requires binding of agonist to both types of subunits.  
[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]
