Comments
Nrf2 is a member of the basic leucine zipper transcription factor subfamily featuring a Cap "n" collar motif. Under unstressed conditions, Nrf2 is found mainly sequestered in the cytoplasm bound to Keap1. When challenged with oxidative stress, Nrf2 is quickly released from Keap1 and translocate into the nucleus. Three NLSs have been proposed. Two NESs were identified. One (aa 503-567) is located at the C-terminus overlapping with the bZip motif and is redox-insensitive. The other one (aa 178-311) is located near the N-terminal in the Neh5 transactivation domain. The N-terminal NES was shown to be redox-sensitive. Only the C-terminal NES was shown to bind CRM1. Both are LMB sensitive. Residues 312-324 is not NES although it conforms to NES consensus.

User Input
Accurate identification of NESs is difficult because many sequences in the genome match the NES consensus. Therefore, some published NESs may be mistakenly identified. Please help us improve the accuracy of NESdb by providing either a positive or negative flag for the NES in this entry. Supporting comments are required to process the flag.
