| Research Abstract |
In this study, we investigated the physiological function of stress sensor Keap1 by mouse genetics. We have found that partial repression of Keap1 leads to activation of transcriptional factor Nrf2, resulting in up-regulation of detoxifying enzymes and anti-oxidant proteins, which is effective for cytoprotection. We have further found that functional Keap1 homodimer is essential for Nrf2 repression, which is disrupted by stress stimuli.
