Figure 8. Sesn2 serves as antioxidants by improving P62-dependent autophagic degradation of Keap1 and thereby promoting Nrf2 expression and activity. When Sesn2 binds to P62 and Keap1, P62 binds to LC3 simultaneously at autophagosomes and thereby promote Keap1 degradation. The degradation of Keap1 was found to have led to Nrf2 expression and activation, and then promoted the transcription of genes for various antioxidant enzymes.
