Comments
Bach1 is a transcription repressor of the heme oxygenase-1 (HO-1) gene. HO-1 is essential for higher eukaryotes to cope with various aspects of cellular stress and to regulate cellular iron metabolism. Heme induces the nuclear export of Bach1 through CRM1-mediated pathway, thus induces the transcription of HO-1.

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.
