AMPK: regulating energy balance at the cellular and whole body levels

Physiology (Bethesda). 2014 Mar;29(2):99-107. doi: 10.1152/physiol.00050.2013.


AMP-activated protein kinase appears to have evolved in single-celled eukaryotes as an adenine nucleotide sensor that maintains energy homeostasis at the cellular level. However, during evolution of more complex multicellular organisms, the system has adapted to interact with hormones so that it also plays a key role in balancing energy intake and expenditure at the whole body level.
