There are three major regulatory proteins in the IκB (inhibitor of NFκB) family:IκBα, IκBβ, and IκBε. all sharing a common domain structure. Lee et al. investigated the cellular distribution of IκBε. They found that IκBε is a cytoplasmic protein. However, in the presence of reticuloctye lysate and an energy regenerating system, nuclear accumulation of IκBε can be observed. The nuclear import of IκBε is less efficient than IκBα. Like IκBα, the import is not dependent on GTP hydrolysis. Treating the cell with LMB enhances the nuclear accumulation. Removal of the last 21 aa caused nuclear accumulation. They also showed that IκBε binds to CRM1 in vitro, and only in the presence of RanGTP. Mutating L489 and I491 to alanines will abolish the in vitro binding. The same double mutation resulted in a whole cell distribution of IκBε. They postulated that IκBε functions in the nucleus to direct the export of NF-κB/Rel proteins back to the cytoplasm. Note that the sequence given in the paper is 139 shorter than the sequence in SwissProt.

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.
