Western blot analysis of PRKAA2 over-expressed 293 cell line, cotransfected with PRKAA2 Validated Chimera RNAi ( Cat # H00005563-R01V ) (Lane 2) or non-transfected control (Lane 1). Blot probed with PRKAA2 monoclonal antibody (M02) clone 1G8 (Cat # H00005563-M02 ). GAPDH ( 36.1 kDa ) used as specificity and loading control.
The protein encoded by this gene is a catalytic subunit of the AMP-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 thus phosphorylates and inactivates acetyl-CoA carboxylase (ACC) and beta-hydroxy beta-methylglutaryl-CoA reductase (HMGCR), key enzymes involved in regulating de novo biosynthesis of fatty acid and cholesterol. Studies of the mouse counterpart suggest that this catalytic subunit may control whole-body insulin sensitivity and is necessary for maintaining myocardial energy homeostasis during ischemia.
