Components
cell junction / cell surface / integral component of plasma membrane / neuron projection / neuronal postsynaptic density / NMDA selective glutamate receptor complex / plasma membrane / postsynaptic membrane / synaptic vesicle
General Function
Zinc ion binding
Specific Function
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).
