AMPK plays a key role in the regulation of energy homeostasis.
It acts as a metabolic stress-inducing protein kinase that switches off biosynthetic pathways when cellular ATP levels are low and when 5`-AMP rises in response to fuel limitation.
AMPK is activated by high AMP and low ATP via a mechanism that involves allosteric regulation, promotion of phosphorylation by an upstream protein kinase known as AMPK kinase, and inhibition of dephosphorylation.
Activated AMPK can phosphorylate and regulate in vivo hydroxymethylglutaryl-CoA reductase and acetyl-CoA carboxylase.
May increase the rate of glucose oxidation in muscle by increasing the rate of glucose transport.
Shows homology to yeast protein kinase-encoding gene (snf1) regulating carbohydrate metabolism.
Human AMPKg2 is a 569 aa protein, which contains unique N-terminal domains and participate in binding of AMP within the AMPK complex.
AMPK is a heterotrimeric complex composed of a catalytic subunit and two regulatory subunits.
Three isoforms of the gamma subunit exist in the brain with gamma 2 and gamma 3 present, which is distinct from the rat liver gamma 1 isoform.
The noncatalytic subunits of AMPK are related to proteins that interact with snf1p; the beta subunit is related to the SIP1/SIP2/ GAL83 family of transcription regulators and the gamma subunit to SNF4.3 Mutations in AMPKgamma 2 can cause familial hypertrophic cardiomyopathy (HCM), which provides evidence for the central role of energy compromise in disease pathogenesis.
