AMPK alpha-1/beta-1/gamma-2 Proteins

Protein Information

AMPK (A1/B1/G2) is a member of the AMPK family which are heterotrimeric proteins consisting of an alpha catalytic subunit, and non-catalytic beta and gamma subunits. AMPKs are an important energy-sensing enzyme group in the cells that monitor energy status particularly in response to stress. AMPKs regulate fatty acid and cholesterol synthesis by regulating the key rate-limiting enzymes acetyl-CoA carboxylase and hydroxy beta-methylglutaryl-CoA reductase. The beta subunit may be a positive regulator of AMPK activity and is highly expressed in skeletal muscle.
