ARF–NRF2: A new checkpoint for oxidative stress responses?

Abstract

NRF2 (nuclear factor erythroid 2-related factor 2) is a transcription factor which plays a major role in oxidative stress responses by regulating antioxidant gene expression. We have recently identified the ARF tumor suppressor as a key regulator of NRF2. ARF can significantly inhibit NRF2 transcriptional activities, and the ARF-NRF2 interaction may function as a novel checkpoint for oxidative stress responses.
