Anti-NMDAR2B (phospho S1166) antibody

Target data

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 : 11929923, PubMed : 19910922, PubMed : 21677647, PubMed : 24607230, PubMed : 24876489, PubMed : 27135925, PubMed : 7524561). Participates in synaptic plasticity for learning and memory formation by contributing to the long-term depression (LTD) of hippocampus membrane currents (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 : 11929923, PubMed : 19910922, PubMed : 21677647, PubMed : 24607230, PubMed : 24876489, PubMed : 27135925, PubMed : 7524561). NMDARs mediate simultaneously the potassium efflux and the influx of calcium and sodium (By similarity). Each GluN2 subunit confers differential attributes to channel properties, including activation, deactivation and desensitization kinetics, pH sensitivity, Ca2(+) permeability, and binding to allosteric modulators (PubMed : 10436042, PubMed : 11929923, PubMed : 24607230, PubMed : 9463421). In concert with DAPK1 at extrasynaptic sites, acts as a central mediator for stroke damage (By similarity). 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).
