Specific for the ~120k NR1 subunit of the NMDA Receptor containing the C2 splice variant insert. Does not recognize the NR1 subunits of the NMDA receptor that do not contain the C2 insert.

Affinity Purified (Prepared from rabbit serum by affinity purification using a column to which the peptide immunogen was coupled.)

25 ug antibody vial; lyophilized from 5 mM ammonium bicarbonate. The antibody should be reconstituted in 50 ul phosphate buffered saline (PBS: 137 mM NaCl, 7.5 mM Na2HPO4, 2.7 mM KCl, 1.5 mM KH2PO4, pH 7.4) before use. After reconstitution the antibody sh

For long term storage -20 degree C is recommended. Stable at -20 degree C for at least 1 year.

Western Blot (WB), Immunohistochemistry (IHC)

Quality Control: Western blots performed on each lot. WB: 1:1000. IHC (frozen sections; unpublished observations): 1:1000 to 1:2000

Antigen: Peptide from the NR1 subunit, C2 splice variant insert of rat NMDA receptor. Immunogen Information: Synthetic peptide corresponding to amino acid residues specific to the NR1 subunit, C2 splice variant insert conjugated to KLH. Immunogen Species: Rat

Reactivity Assumed Based on 100% Sequence Homology: Human. Species Reactivity Note: The antibody has been directly tested for reactivity in Western blots in rat and mouse tissues. It is anticipated that the antibody will also work with human tissues based on the fact that this species has 100% homology with the amino acid sequence used as antigen. Biological Significance: The ion channels activated by glutamate that are sensitive to N-methyl-D-aspartate (NMDA) are designated NMDA Receptors (NMDAR). The NMDAR plays an essential role in memory, neuronal development and it has also been implicated in several disorders of the central nervous system including Alzheimer's, epilepsy and ischemic neuronal cell death (Grosshans et al., 2002; Wenthold et al., 2003; Carroll and Zukin, 2002). There are a number of different splice variants of the NR1 subunit (Foldes et al., 1994; Zukin and Bennett, 1995). Differential splicing of three exons in the NR1 subunit generates up to eight NR1 subunit splice variants and 7 of these have been identified in cDNA libraries. These exons encode a 21 amino acid N-terminal domain (N1) and adjacent sequences in the C-terminus (C1 and C2). Splicing out the C2 cassette eliminates the first stop codon and produces a new reading frame that generates a new sequence of 22 amino acids (C2'). Considerable attention has been focused on the distribution and expression of these splice variants that may affect the functional properties and regulation of the NMDAR.

subunit of NMDA-preferring ionotropic glutamate receptors; may play a role in long term potentiation [RGD, Feb 2006]

Function: 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. Ref.18. Subunit structure: 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 . By similarity. Found in a complex with GRIN2A or GRIN2B, GRIN3A and PPP2CB. Found in a complex with GRIN2A or GRIN2B and GRIN3B. Interacts with SNX27 (via PDZ domain); the interaction is required for recycling to the plasma membrane when endocytosed and prevent degradation in lysosomes . By similarity. Interacts with DLG4 and MPDZ. Interacts with LRFN1 and LRFN2. Interacts with MYZAP. Ref.7 Ref.8 Ref.9 Ref.10 Ref.11 Ref.13 Ref.14 Ref.15 Ref.17. Subcellular location: Cell membrane; Multi-pass membrane protein . By similarity. Cell junction synapse postsynaptic cell membrane . By similarity. Cell junction synapse postsynaptic cell membrane postsynaptic density . By similarity. Note: Enriched in postsynaptic plasma membrane and postsynaptic densities . By similarity. Post-translational modification: NMDA is probably regulated by C-terminal phosphorylation of an isoform ofNR1 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. Ref.7 Ref.12. Sequence similarities: Belongs to the glutamate-gated ion channel (TC 1.A.10.1) family. NR1/GRIN1 subfamily. [View classification]
