Species cross-reactivity is determined by Western blot.
Specificity / Sensitivity
NMDAR2A Antibody detects endogenous levels of total NMDAR2A protein. This antibody cross-reacts with an unidentified protein at ~70kDa.
Source / Purification
Polyclonal antibodies are produced by immunizing rabbits with a synthetic peptide (KLH-coupled) corresponding to human NMDAR2A. Antibodies are purified peptide affinity chromatography.
Western Blotting
Western blot analysis of extracts from rat and mouse brain using NMDAR2A Antibody.
Background
N-methyl-D-aspartate receptor (NMDAR) forms a heterodimer of at least one NR1 and one NR2A-D subunit. Multiple receptor isoforms with distinct brain distributions and functional properties arise by selective splicing of the NR1 transcripts and differential expression of the NR2 subunits. NR1 subunits bind the co-agonist glycine and NR2 subunits bind the neurotransmitter glutamate. Activation of the NMDA receptor or opening of the ion channel allows flow of Na+ and Ca2+ ions into the cell, and K+ out of the cell (1). Each subunit has a cytoplasmic domain that can be directly modified by the protein kinase/phosphatase (2). PKC can phosphorylate the NR1 subunit (NMDAR1) of the receptor on Ser890/Ser896, and PKA can phosphorylate NR1 on Ser897 (3). The phosphorylation of NR1 by PKC decreases its affinity for calmodulin, thus preventing the inhibitory effect of calmodulin on NMDAR (4). The phosphorylation of NR1 by PKA probably counteracts the inhibitory effect of calcineurin on the receptor (5). NMDAR mediates long-term potentiation and slow postsynaptic excitation, which play central roles in learning, neurodevelopment and neuroplasticity (6).
