The homeodomain protein Extradenticle (Exd) is required along with another protein, Homothorax, with shuttling ability for proper Drosophila development. Although not proven to be sufficient and relatively weak when compared to Exd's NLS activity, amino acids 209-218 are cited to be a functional NES. In proximal cells, it is assumed that Hth deactivates the NES, making the Hth-Exd dimer is nuclear. PBX1 is a homolog of Exd. To promote Exd's cytoplasmic localization, the N-terminus binds its own homeodomain and masks the NLSs.
One NES was identified in PBX1 located around aa 70-90. Two NESs identified individually from the two proteins are well aligned.

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.
