Background
Phospho-AMPKα (Thr183/Thr172) corresponds to the conserved activating phosphorylation sites of AMPKα1 and AMPKα2 subunits, which are the hallmark modifications for full AMPK activation. Thr172 on AMPKα2 and Thr183 on AMPKα1 are located in the kinase activation loop, and their phosphorylation is a prerequisite for initiating AMPK catalytic activity and downstream signaling. As a central energy sensor, activated AMPK suppresses anabolic metabolism, promotes catabolic processes, and regulates autophagy, oxidative stress, inflammation and cell growth. Deficient AMPK phosphorylation is a typical pathological feature of metabolic syndrome, aging-related diseases and malignant tumors.
