Comments
Dfd is a homeodomain-containing transcription factor critical for development. Duffraisse et al. found that Dfd also contains a putative NES similar to Ubx (entry 395), but it follows conventional class 1a pattern in residues 341-352 including the W-containing HEX motif. HEX motif is known to be critical for binding to co-factors for DNA-binding. Interaction with drosophila CRM1 Embargoed is illustrated by biomolecular fluorescence complementation, where HEX mutations affected the observed interaction (but only in the cytoplasm - signal remained in the nucleus). Co-expression with Emb also caused cytoplasmic accumulation of Dfd 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.
