Abstract

The cytoplasmic C termini of AMPA receptor subunits contain PDZ (postsynaptic density 95/Discs large/zona occludens 1) ligand domains that can control their synaptic trafficking during plasticity. The glutamate receptor subunit 2 (GluR2) PDZ ligand domain can be phosphorylated at serine 880 (S880), and this disrupts interactions with GRIP/ABP (glutamate receptor-interacting protein/AMPA-binding protein) but not with PICK1 (PKC-interacting protein 1). Here, the impact of GluR2 S880 phosphorylation on synaptic transmission and plasticity was explored by expressing, in hippocampal slice cultures, GluR2 subunits containing point mutations that mimic or prevent phosphorylation at this residue. Our results indicate that mimicking GluR2 S880 phosphorylation excludes these receptors from synapses, depresses transmission, and partially occludes long-term depression (LTD). Conversely, mutations that prevent phosphorylation reduce LTD. Disruption of the interaction between GluR2 and GRIP/ABP by S880 phosphorylation may thus facilitate removal of synaptic AMPA receptors and mediate some forms of activity-dependent synaptic depression.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Phosphorylation of GluA2 S880 prevents GRIP1/2 binding, promotes interaction of the GluA2 PDZ ligand with PICK1, destabilizes GluA2 within the PSD, and promotes GluA2 endocytosis.

    “Phosphorylation of GluA2 S880 prevents GRIP1/2 binding and promotes the interaction of the GluA2 PDZ ligand with PICK1 (Seidenman et al., 2003, Chung et al., 2000, Steinberg et al., 2006), destabilizing GluA2 within the PSD and promoting GluA2 endocytosis.”

  • The GluA2 S880 phosphorylation site is important in hippocampal LTD.

    “The GluA2 S880 phosphorylation site has also been shown to be important in hippocampal LTD (Seidenman et al., 2003, Chung et al., 2000, Steinberg et al., 2006).”

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.
