TL;DR

The results suggest that a major function of the AMP-activated protein kinase is to act protectively, switching off biosynthetic pathways when the cell is subjected to stress that causes ATP depletion, the key signal being a rise in AMP level.

Abstract

Our results suggest that a major function of the AMP-activated protein kinase is to act protectively, switching off biosynthetic pathways when the cell is subjected to stress that causes ATP depletion, the key signal being a rise in AMP level. By this mechanism, ATP is preserved for processes that may be more essential in the short term, such as the maintenance of ion gradients. This function of the kinase represents a novel role for protein phosphorylation.
