General description

Glutamate receptors (GluRs) can be categorized as ionotropic or metabotropic and subcatergorized by their agonist preferences (NMDA, AMPA or Kainic acid). There are four types of AMPA selective GluR subunits (GluR1, GluR2, GluR3 and GluR4). Tetrameric or pentameric combinations of different subunits contributes to the functional diversity of AMPA receptors. In general, AMPA receptors mediate fast synaptic current at most excitatory synapses, with stoichiometry characterized by subtype composition. Although subunit composition of AMPA receptors varies, they must contain at least one edited GluR2 subunit to be calcium impermeable. The critical residue controlling calcium permeability is in the pore loop region. In GluR1, GluR3, and GluR4, this positionis occupied by a Gln residue. In GluR2, it is occupied by an Arg residue. It has been shown experimentally that the presence of Arg in this position blocks CA2+ ion permeability, while a Gln does not. Relative calcium permeability in AMPA receptor channels may be significant in pathological neurotoxic damage and long term changes in nervous system responses.
The unconjugated parent antibody (Cat. No. MAB397) has an observed molecular weight at ~102 kDa

Pathways and Biomarkers of Glutamatergic Synapse Flyer

Glutamate is an excitatory neurotransmitter found in the synaptic vesicles of glutamatergic synapses. The post-synaptic neurons in these synapses contain ionotropic and metabotropic glutamate receptors. Glutamate binds to AMPA (α-amino-3-hydroxy-5- methylisoxazole-4-propionic acid) subtype glutamate receptors, leading to sodium influx into the post-synaptic cell and resulting in neuronal excitability and synaptic transmission. The NMDA (N-methyl-d-aspartate) subtype glutamate receptors, on the other hand, regulate synaptic plasticity, and can influence learning and memory. The metabotropic g-protein coupled mGluRs modulate downstream calcium signaling pathways and indirectly influence the synapse’s excitability. The synaptic architecture includes intracellular scaffolding proteins (PSD-95, GRIP), intercellular cell adhesion molecules (NCAMs, N-Cadherins), and a variety of signaling proteins (CaMKII/PKA, PP1/PP2B). Processes critical for synaptic transmission and plasticity are influenced by these molecules and their interactions. When the function of these molecules is disrupted, it leads to synaptic dysfunction and degeneration, and can contribute to dementia as seen in Alzheimer’s disease.
