In the mammalian central nervous system, glutamate and its receptors (GluR) are the major excitatory neurotransmitter and receptor, respectively.
Imbalances in glutamatergic function have been implicated in neuronal death following ischemia, hypoglycemia or anoxia, epilepsy, and in neurodegenerative disorders.
Based on their activation by different pharmacologic agonists GluR have been classified into two major superfamilies: the ligand-gated ion channel receptors referred to as ionotropic GluR (iGluR), and the G-protein-coupled receptors referred to as metabotropic GluR (mGluR).
The iGluR respond to selective agonists and are thus defined as the N-methyl-D-aspartate (NMDA) receptors, the alphaamino-3-hydroxy-5-methyl-isoxasole-4-propionate (AMPA) responsive receptors (GluR1, 2, 3 and 4) and the kainate responsive receptors (GluR5 and 6).
GluR1 is phosphorylated on multiple sites, all are located on the C-terminal of the protein.
Ligand induced phosphorylation of GluR1 seems to be site-specific.
In one study, using transfected HEK cells and neurons in culture, cyclic AMP-dependent protein kinase specifically phosphorylates Ser845 of GluR11.
In addition, protein kinase C specifically phosphorylates Ser831 of GluR12.
The phosphorylation pattern of GluR1 by PKA and PKC is consistent with the study of AMPA-Rs in cortical neurins and GluR1 expressed in 293 cells.
These results suggested that the function of GluR1 can be regulated by protein phosphorylation.
