Comments
HoxA5 is a homeodomain-containing transcription factor critical for developmental regulation. Duffraisse et al. found that human HOXA5 also contains a putative NES similar to Drosophila Ubx/Dfd/Scr (entries 394-396) including the W-containing HEX motif (sequence displayed in figure is of wrong sequence but a consensus match can be found in residues 176-186). HEX motif is known to be critical for binding to co-factors for DNA-binding. Co-expression of CRM1 caused cytoplasmic accumulation of HoxA5 which is dependent on intact HEX motif.

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.
