AMP-activated protein kinase

AMP-activated protein kinase (pronounced as A-M-P activated protein kinase), often abbreviated as AMPK, is an enzyme that plays a crucial role in cellular energy homeostasis. It is found in the cells of various organs, including the liver, brain, and skeletal muscle.

Etymology

The term "AMP-activated protein kinase" is derived from the fact that the enzyme is activated by Adenosine Monophosphate (AMP), a type of nucleotide that is involved in cellular energy transfer.

Function

AMP-activated protein kinase functions as a metabolic master switch. It regulates an array of biological activities, including the cellular uptake of glucose, the beta-oxidation of fatty acids, and the biogenesis of GLUT4 and mitochondria.
