AMPK signaling pathway

AMP-activated protein kinase

AMP-activated protein kinase (AMPK) is a nuclear receptor which regulates cellular uptake of glucose, β-oxidation of fatty acids and biogenesis of glucose transporter thus playing a role in cellular energy homeostasis by phosphorylating key proteins. In response to low levels of ATP, AMPK activates energy-producing pathways and inhibits energy-consuming pathways.
