Regulation of brain Type II Ca2+/calmodulin-dependent protein kinase by autophosphorylation: A Ca2+-triggered molecular switch

Miller, S·1986·Cell

Abstract

Calcium/calmodulin-stimulated autophosphorylation of a prominent brain calmodulin-dependent protein kinase (Type II CaM kinase) produces dramatic changes in its enzymatic activity. These changes suggest a mechanism by which the kinase could act as a calcium-triggered molecular switch. Incorporation of 3-12 of a possible total of 30 phosphate groups per holoenzyme causes kinase activity toward exogenous substrates as well as autophosphorylation itself to become independent of calcium. Thus, kinase activity could be prolonged beyond the duration of an initial activating calcium signal. The calcium-independent autophosphorylation could further prolong the active state by opposing dephosphorylation by cellular phosphatases.

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?

  • CaMKII becomes independent of Ca2+ (autonomous) after autophosphorylation.

    “it was not until the discovery of a Ca2+/calmodulin-dependent protein kinase, now referred to as CaMKII (9, 10), which became independent of Ca2+ (autonomous) after autophosphorylation (11–15)”

    From Synaptic memory and CaMKII (2023) · cites this paper as [15]

  • CaMKII exhibits switchlike autonomy after autophosphorylation of just a minority of its subunits.

    “and exhibited switchlike autonomy after autophosphorylation of just a minority of its subunits (15)”

  • Once activated by Ca2+, CaMKII enzymatic activity toward substrates remains after Ca2+ removal.

    “Fourth, CaMKII has the intriguing property that once activated by Ca2+ the enzymatic activity toward substrates remains after Ca2+ removal (11–15).”

    From Synaptic memory and CaMKII (2023) · cites this paper as [15]

  • The subunit being phosphorylated apparently needs to have Ca2+/CaM bound; phosphorylation does not significantly occur on inactive subunits.

    “A further complication for either of these possibilities is that it appears that the subunit being phosphorylated apparently would need to have Ca2+/CaM bound, i.e., it does not significantly occur on inactive subunits (13, 15, 82, 83, 406).”

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.
