Translational control of Nrf2 within the open reading frame.

ABSTRACT: Nuclear Factor Erythroid 2-Related Factor 2 (Nrf2) is a transcription factor that is essential for the regulation of an effective antioxidant and detoxifying response. The regulation of its activity can occur at transcription, translation and post-translational levels. Evidence suggests that under environmental stress conditions, new synthesis of Nrf2 is required - a process that is regulated by translational control and is not fully understood. Here we described the identification of a novel molecular process that under basal conditions strongly represses the translation of Nrf2 within the open reading frame (ORF). This mechanism is dependent on the mRNA sequence within the 3' portion of the ORF of Nrf2 but not in the encoded amino acid sequence. The Nrf2 translational repression can be r
