  • Target

    • Function
      NMDA receptor subtype of glutamate-gated ion channels with high calcium permeability and voltage-dependent sensitivity to magnesium. Mediated by glycine.
    • Tissue specificity
      Primarily found in the fronto-parieto-temporal cortex and hippocampus pyramidal cells, lower expression in the basal ganglia.
    • Sequence similarities
      Belongs to the glutamate-gated ion channel (TC 1.A.10.1) family. NR2B/GRIN2B subfamily.
    • Cellular localization
      Cell membrane. Cell junction > synapse > postsynaptic cell membrane.
