AMP-activated protein kinase: an energy sensor that regulates all aspects of cell function

Open access
Hardie, D. Grahame·2011·Genes & Development

Abstract

AMP-activated protein kinase (AMPK) is a sensor of energy status that maintains cellular energy homeostasis. It arose very early during eukaryotic evolution, and its ancestral role may have been in the response to starvation. Recent work shows that the kinase is activated by increases not only in AMP, but also in ADP. Although best known for its effects on metabolism, AMPK has many other functions, including regulation of mitochondrial biogenesis and disposal, autophagy, cell polarity, and cell growth and proliferation. Both tumor cells and viruses establish mechanisms to down-regulate AMPK, allowing them to escape its restraining influences on growth.

  • To increase ATP availability, the cells increase the catabolism of energy stores, such as fatty acids, and the biosynthesis of costly fatty acids and ergosterol is decreased.

    The Regulation of metabolism section (page unavailable) says AMPK promotes ATP-generating catabolic pathways, including fatty acid oxidation, while inhibiting fatty acid synthesis. It also reports inhibition of isoprenoid synthesis, but does not specifically establish decreased ergosterol biosynthesis, particularly in yeast cells. (LLM, conf=0.85)

  • AMPK is considered a bioenergetic sensor that responds to increased AMP and decreased ATP levels by increasing phosphorylation at threonine 172 of its α1 subunit.

    “AMP kinase (AMPK) is considered a bioenergetic sensor that responds to increased AMP and decreased ATP levels by increasing phosphorylation at threonine 172 of its α1 subunit.”
  • AMPK inactivates energy-consuming growth-promoting pathways like protein and lipid synthesis and activates catabolism of fatty acids and other fuels, rebalancing energy supply with demand.

    “By phosphorylating a number of key targets, AMPK inactivates energy-consuming, growth-promoting pathways like protein and lipid synthesis, and activates catabolism of fatty acids and other fuels. This enables the cell to re-balance energy supply with demand.”

    From Cellular Metabolism and Disease: What Do Metabolic Outliers Teach Us? (2012) · cites this paper as Hardie, 2011

  • AMPK is a fuel sensor activated during compromised bioenergetic states such as acute nutrient deprivation and hypoxia.

    “This serine-threonine kinase is a “fuel sensor” activated during compromised bioenergetic states such as acute nutrient deprivation and hypoxia (Hardie, 2011).”

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.
