AMP-activated protein kinase: Also regulated by ADP?

Hardie, D. Grahame, Carling, David, Gamblin, Steven J.·2011·Trends in Biochemical Sciences

Abstract

AMPK is a ubiquitous sensor of cellular energy status in eukaryotic cells. It is activated by stresses causing ATP depletion and, once activated, maintains energy homeostasis by phosphorylating targets that activate catabolism and inhibit energy-consuming processes. Evidence derived from non-mammalian orthologs suggests that its ancestral role was in the response to starvation for a carbon source. We review recent findings showing that AMPK is activated by ADP as well as AMP, and discuss the mechanism by which binding of these nucleotides prevent its dephosphorylation and inactivation. We also discuss the role of the carbohydrate-binding module on the β subunit and the mechanisms by which it is activated by drugs and xenobiotics such as metformin and resveratrol.

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.
