The protein encoded by this gene is a critical subunit of N-methyl-D-aspartate receptors, members of the glutamate receptor channel superfamily which are heteromeric protein complexes with multiple subunits arranged to form a ligand-gated ion channel. These subunits play a key role in the plasticity of synapses, which is believed to underlie memory and learning. The gene consists of 21 exons and is alternatively spliced, producing transcript variants differing in the C-terminus.



Score>80(red) has high confidence and is suggested to be used for WB detection. *The prediction model is mainly based on the alignment of immunogen sequences, the results are for reference only, not as the basis of quality assurance.

Research Backgrounds


Component of NMDA receptor complexes that function as heterotetrameric, ligand-gated ion channels with high calcium permeability and voltage-dependent sensitivity to magnesium. Channel activation requires binding of the neurotransmitter glutamate to the epsilon subunit, glycine binding to the zeta subunit, plus membrane depolarization to eliminate channel inhibition by Mg(2+). Sensitivity to glutamate and channel kinetics depend on the subunit composition.


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.

Subunit Structure:

Heterotetramer. Forms heterotetrameric channels composed of two zeta subunits (GRIN1), and two epsilon subunits (GRIN2A, GRIN2B, GRIN2C or GRIN2D) (in vitro). Can also form heterotetrameric channels that contain at least one zeta subunit (GRIN1), an epsilon subunit, plus GRIN3A or GRIN3B (in vitro). In vivo, the subunit composition may vary in function of the expression levels of the different subunits. Found in a complex with GRIN2A or GRIN2B, GRIN3A and PPP2CB (By similarity). Found in a complex with GRIN2A or GRIN2B and GRIN3B (By similarity). 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 (By similarity). Interacts with MYZAP. Found in a complex with DLG4 and PRR7 (By similarity). Found in a complex with GRIN2B and PRR7. Interacts with PRR7; the interaction is reduced following NMDA receptor activity.


A hydrophobic region that gives rise to the prediction of a transmembrane span does not cross the membrane, but is part of a discontinuously helical region that dips into the membrane and is probably part of the pore and of the selectivity filter.

Belongs to the glutamate-gated ion channel (TC 1.A.10.1) family. NR1/GRIN1 subfamily.

FIGURE 5| STK24 is a potential binding partner of the NMDAR complex in the hippocampus of PTZ-kindled mice. A, STK24 interacts with the NMDAR complex, but not with the AMPAR complex. Hippocampal lysates from PTZkindled mice were immunoprecipitated with STK24 antibody and incubated with corresponding antibodies (IB: immunoblotting, IP: immunoprecipitation). B–F, Lysates from hippocampus of PTZkindled mice were immunoprecipitated with antibodies against NR1(B), NR2A(C), NR2B(D), GluR1(E), GluR2(F), and incubated with corresponding antibodies

Data of Western blot analysis (mean±SD) are expressed as the ratio of the relative contents between the value from IDA group and NG group and six iron treatment groups (n=3). Te relative contents of target proteins were quantifed using the ratio between the optical density (OD) of target protein and the amount of the housekeeping protein GAPDH. **p<0.01, compared with NG, #p<0.05, ##p<0.01, compared with IDAG. One-way ANOVA followed by Tukey multiple comparison test was used for comparison among 8 diferent groups.
