      Background InformationNR1 (NMDA1or NMDAR1, also known as GRIN1) along with the NR2 subunit forms a heterodimer that make up the NMDA receptor. The NMDA receptor (NMDAR) is characterized as a ionotropic receptor for glutamate. As the name suggests, (NMDA (N-methyl D-aspartate) is an agonist for the receptor. A distinct characteriztic of the NMDA receptor is that it is both ligand-gated and voltage-dependent based on its sensitivity to magnesium. Activated NMDA receptors result in the opening of an ion channel that is nonselective to cations. The result is the flow of Na+ and small amounts of Ca2+ ions into the cell and K+ out of the cell. Calcium flux by the NMDARs has been implicated in synaptic plasticity, a mechanism in the cell for learning and memory.

      Key Applications
      • Immunocytochemistry
      • Immunoprecipitation
      • Western Blotting
      Application NotesImmunoprecipitation:
      4 μg of a previous lot immunoprecipitated NR1 from 500mg of rat brain microsomal protein preparation.

      An independent laboratory has shown positive staining in QT-6 cells, transfected to express NR1, which were fixed with 4% paraformaldehyde/4% sucrose in PBS and in nontransfected cultured rat neurons.

      Note: Do not boil the microsomal preparation. Incubate at room temperature for 30-45 minutes.
      Biological Information
      ImmunogenHis-tag fusion protein corresponding to residues 834-938 of rat NR1A. The immunizing sequence is identical in rat and human.
      EpitopeThe epitope maps to a region (a.a. 834-864) common to all NR1 isoforms
      ConcentrationPlease refer to the Certificate of Analysis for the lot-specific concentration.
      SpecificityThis antibody is specific for NR1, Mr 130 kDa. The epitope maps to a region (834-864) common to all NR1 isoforms and so should cross react with all NR1 isoforms. An additional band may be detected at higher concentrations, Mr 200kDa.

      UniProt Number
      UniProt SummaryFUNCTION: NMDA receptor subtype of glutamate-gated ion channels possesses high calcium permeability and voltage-dependent sensitivity to magnesium. Mediated by glycine. Plays a key role in synaptic plasticity, synaptogenesis, excitotoxicity, memory acquisition and learning. It mediates neuronal functions in glutamate neurotransmission. Is involved in the cell surface targeting of NMDA receptors.

      SUBUNIT: Forms heteromeric channel of a zeta subunit (GRIN1), a epsilon subunit (GRIN2A, GRIN2B, GRIN2C or GRIN2D) and a third subunit (GRIN3A or GRIN3B); disulfide-linked. Found in a complex with GRIN2A or GRIN2B, GRIN3A or GRIN3B and PPP2CB. Interacts with DLG4 and MPDZ

      SUBCELLULAR LOCATION: Cell membrane; Multi-pass membrane protein, Cell junction › synapse › postsynaptic cell membrane. Cell junction › synapse › postsynaptic cell membrane › postsynaptic density. Note: Enriched in post-synaptic plasma membrane and post-synaptic densities.

      POST-TRANSLATIONAL MODIFICATION: NMDA is probably regulated by C-terminal phosphorylation of an isoform of NR1 by PKC. Dephosphorylated on Ser-897 probably by protein phosphatase 2A (PPP2CB). Its phosphorylated state is influenced by the formation of the NMDAR-PPP2CB complex and the NMDAR channel activity.
