5'-AMP-activated protein kinase catalytic subunit alpha-2 is anenzyme that in humans is encoded by thePRKAA2gene.^[5]^[6]

Function

[edit]

Theprotein encoded by this gene is a catalytic subunit of theAMP-activated protein kinase (AMPK). AMPK is a heterotrimer consisting of an alpha catalytic subunit, and non-catalytic beta and gamma subunits. AMPK is an important energy-sensing enzyme that monitors cellular energy status. In response to cellular metabolic stresses, AMPK is activated, and thusphosphorylates and inactivatesacetyl-CoA carboxylase (ACC) and beta-hydroxy beta-methylglutaryl-CoA reductase (HMGCR), key enzymes involved in regulating de novobiosynthesis offatty acid andcholesterol. Studies of the mouse counterpart suggest that this catalytic subunit may control whole-bodyinsulin sensitivity and is necessary for maintaining myocardial energy homeostasis duringischemia.^[6]
