Abstract

Modulation of alpha-amino-3-hydroxy-5-methylisoxazole-4-propionic Acid (AMPA) receptors in the brain by protein phosphorylation may play a crucial role in the regulation of synaptic plasticity. Previous studies have demonstrated that calmodulin (CaM) kinase II can phosphorylate and modulate AMPA receptors. However, the sites of CaM kinase phosphorylation have not been unequivocally identified. In the current study, we have generated two phosphorylation site-specific antibodies to analyze the phosphorylation of the glutamate receptor GluR1 subunit. These antibodies recognize GluR1 only when it is phosphorylated on serine residues 831 or 845. We have used these antibodies to demonstrate that serine 831 is specifically phosphorylated by CaM kinase II in transfected cells expressing GluR1 as well as in hippocampal slice preparations. Two-dimensional phosphopeptide mapping experiments indicate that Ser-831 is the major site of CaM kinase II phosphorylation on GluR1. In addition, treatment of hippocampal slice preparations with phorbol esters and forskolin increase the phosphorylation of serine 831 and 845, respectively, indicating that protein kinase C and protein kinase A phosphorylate these residues in hippocampal slices. These results identify the site of CaM kinase phosphorylation of the GluR1 subunit and demonstrate that GluR1 is multiply phosphorylated by protein kinase A, protein kinase C, and CaM kinase II in situ.

  • NMDAR-dependent LTP requires Ca2+ influx leading to activation of CaMKII/PKC which directly phosphorylate GluA1 S831, increasing GluA1 single channel conductance and promoting GluA1 targeting to the PSD.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
