|Calculated MW||166367 Da|
|Other Names||Glutamate receptor ionotropic, NMDA 2B, GluN2B, Glutamate [NMDA] receptor subunit epsilon-2, N-methyl D-aspartate receptor subtype 2B, NMDAR2B, NR2B, N-methyl-D-aspartate receptor subunit 3, NR3, hNR3, GRIN2B, NMDAR2B|
|Target/Specificity||A phospho specific peptide corresponding to residues surrounding serine 1303 of human NMDAR2B was used as an immunogen. This antibody detects NMDAR2B phosphorylated at serine 1303.|
|Format||50 mM Tris-Glycine (pH 7.4), 0.15 M NaCl, 40% Glycerol, 0.01% sodium azide and 0.05% BSA.|
|Storage||Maintain refrigerated at 2-8°C for up to 6 months. For long term storage store at -20°C in small aliquots to prevent freeze-thaw cycles.|
|Precautions||NMDAR2B Antibody Phospho (pS1303) is for research use only and not for use in diagnostic or therapeutic procedures.|
|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).|
|Cellular Location||Cell membrane; Multi-pass membrane protein. Cell junction, synapse, postsynaptic cell membrane; Multi-pass membrane protein|
|Tissue Location||Primarily found in the fronto-parieto-temporal cortex and hippocampus pyramidal cells, lower expression in the basal ganglia.|

The NMDA (N-methyl D-aspartate) receptors in the brain play a critical role in synaptic plasticity, synaptogenesis and excitotoxicity. NMDA R1 and combination of one or more NMDAR2 subunits forms NMDA receptor glutamate-gated ion channels. In this hetromer complex, NMDA R1 binds to co-agonist glycine and NMDA R2 binds to neurotransmitter glutamate (1). Several studies have suggested that protein phosphorylation of NMDA receptors may affect channel function, and additionally regulate these receptors? synaptic trafficking and surface expression. Once activated thru phospholyation, these channels allow movement of Ca2+ and Na+ into the cell and K+ out of the cell. Serine 1303 on NMDAR2B has been identified as a major phospholyation site for CaM kinase II and PKC, regulating kinase-mediated NMNDAR2B/R1 current (2,3). NMDAR has been linked to various neurodegenerative disorders such as schizophrenia, epilepsy, and Alzheimer's disease (4).
