| Introduction | AMPA- (α-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid), kainate-, and NMDA- (N-methyl-D-aspartate) receptors are the three main families of ionotropic glutamate-gated ion channels. AMPA receptors (AMPARs) are comprised of four subunits (GluR 1-4), which assemble as homo- or hetero-tetramers to mediate the majority of fast excitatory transmissions in the central nervous system. AMPARs are implicated in synapse formation, stabilization, and plasticity. In contrast to GluR 2-containing AMPARs, AMPARs that lack GluR 2 are permeable to calcium. Post-transcriptional modifications (alternative splicing, nuclear RNA editing) and post-translational modifications (glycosylation, phosphorylation) result in a very large number of permutations, fine-tuning the kinetic properties of AMPARs. Research studies have implicated activity changes in AMPARs in a variety of diseases including Alzheimer’s, amyotrophic lateral sclerosis (ALS), stroke, and epilepsy.Src family tyrosine kinases phosphorylate the GluR 2 subunit of AMPA receptors at Tyr876, which increases the interaction with GRIP1/2 but not PICK1. In addition, Tyr876 is important for AMPA- and NMDA-induced GluR 2 internalization. |

|---|---|
| Application | WB |
| Dilutions | Western Blot (1:1000) |
| MW(KDa) | 100 |
| Reactivity | Rat |
| Sensitivity | Endogenous |
| Specificity | This antibody detects endogenous levels of GluA2 only when phosphorylated at Tyr869, Tyr873 or Tyr876. It may also detect GluA3 when phosphorylated at the conserved Tyr880, Tyr884 or Tyr887. These residues are not conserved in GluA1 or GluA4. |
