The second mechanism is related to GSK-3, which phosphorylates NRF2 creating a recognition site for β-Transducin Repeat Containing E3 Ubiquitin Protein Ligase (β-TrCP). β-TrCP leads to Cullin-1/Rbx1-mediated NRF2 ubiquitination and its subsequent degradation [8]. Since GSK-3β is inhibited by phosphorylation at Ser9 by Ser/Thr protein kinases such as AKT, it has been suggested that NRF2 might be up-regulated through activation of AKT and permanent inactivation of GSK-3 [9], [10].

NRF2 is regulated principally by two different mechanisms. The best established mechanism is the control of protein stability by Kelch-like ECH-associated protein 1 (KEAP1). KEAP1 is an ubiquitin E3 ligase substrate adapter for a Cullin3/Rbx1-dependent E3 ubiquitin ligase complex; henceforth binding of KEAP1 to NRF2 mediates ubiquitination and subsequent proteasomal degradation of NRF2 [7].
