In contrast, under stress conditions Keap1 activity is inhibited by phosphorylation and free Nrf2 moves to the nucleus, where it binds to ARE in the regulatory regions of cytoprotective proteins and promotes transcription of antioxidant genes such as SOD, glutathione peroxidase (GPx), and GSH, and of phase II detoxifying enzymes such as heme oxygenase-1 (HO-1), glutathione transferases (GST), nicotinamide adenine dinucleotide phosphate (NADPH), and NAD(P)H dehydrogenase [quinone] 1 (NQO1) (Serafini et al., 2019)
