[Back to Kinase LKB1]
Substrate: PRKAA2

Description: 5'-AMP-activated protein kinase catalytic subunit alpha-2(EC (AMPK alpha-2 chain).

Synonyms: AMPK, AMPK2

Ensembl ID: ENSG00000162409

UniprotKB/SwissProt: AAPK2_HUMAN (P54646)

Function: Responsible for the regulation of fatty acid synthesis by phosphorylation of acetyl-CoA carboxylase. It also regulates cholesterol synthesis via phosphorylation and inactivation of hormone-sensitive lipase and hydroxymethylglutaryl-CoA reductase. Appears to act as a metabolic stress-sensing protein kinase switching off biosynthetic pathways when cellular ATP levels are depleted and when 5'-AMP rises in response to fuel limitation and/or hypoxia. This is a catalytic subunit.
