Dynamic Control of CaMKII Translocation and Localization in Hippocampal Neurons by NMDA Receptor Stimulation

Shen, Kang, Meyer, Tobias·1999·Science

Abstract

Calcium-calmodulin-dependent protein kinase II (CaMKII) is thought to increase synaptic strength by phosphorylating postsynaptic density (PSD) ion channels and signaling proteins. It is shown that N-methyl-D-aspartate (NMDA) receptor stimulation reversibly translocates green fluorescent protein-tagged CaMKII from an F-actin-bound to a PSD-bound state. The translocation time was controlled by the ratio of expressed beta-CaMKII to alpha-CaMKII isoforms. Although F-actin dissociation into the cytosol required autophosphorylation of or calcium-calmodulin binding to beta-CaMKII, PSD translocation required binding of calcium-calmodulin to either the alpha- or beta-CaMKII subunits. Autophosphorylation of CaMKII indirectly prolongs its PSD localization by increasing the calmodulin-binding affinity.

Statistics

Recomputing p-values needs the paper’s full text.

Claims the paper makes

This paper’s full text isn’t openly available, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

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

  • Inactive CaMKIIβ, but not α, binds with high affinity to F-actin.

    “A second difference is the specific high-affinity binding of the inactive β, but not α, to F-actin (167–170).”

    From Synaptic memory and CaMKII (2023) · cites this paper as [169]

  • Activation of CaMKII results in the rapid translocation of CaMKII to the PSD.

    “activation of CaMKII results in the rapid translocation of CaMKII to the PSD (137, 140, 169, 216–220).”

    From Synaptic memory and CaMKII (2023) · cites this paper as [169]

  • The Ca2+/CaM-dependent binding and phase separation (LLPS) of CaMKII to GluN2B can occur in the absence of enzymatic activity.

    “It is well established that the Ca2+/CaM-dependent binding and phase separation (LLPS) of CaMKII to GluN2B can occur in the absence of enzymatic activity (169, 323, 376).”

    From Synaptic memory and CaMKII (2023) · cites this paper as [169]

  • As long as Ca2+/CaM is present, binding and phase separation are maintained even with a phosphonull mutant of T286 (T286A) or with a kinase-dead mutant of CaMKII, although the binding of CaMKII to GluN2B is modestly enhanced by T286 phosphorylation.

    “As long as Ca2+/CaM is present, binding and phase separation are maintained even with a phosphonull mutant of T286 (T286A) (78, 169, 323, 377) or with a kinase-dead mutant of CaMKII (169, 323, 378, 379), although the binding of CaMKII to GluN2B is modestly enhanced by T286 phosphorylation (378).”

    From Synaptic memory and CaMKII (2023) · cites this paper as [169]

  • T286 phosphorylation is needed for the persistence of a CaMKII-GluN2B complex.

    “This suggests a need for T286 phosphorylation for persistence of a CaMKII-GluN2B complex (88, 169).”

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.
