Comments
TIS11 proteins contain two tandem repeats of a putative zinc finger motif. TIS11 functions as a positive transcriptional regulator in the nucleus, and is involved in the destablization of certain mRNAs. Murata et al. demonstrated that GFP-TIS11 is localized both in the cytoplasm and the nucleus, and upon LMB treatment a marked nuclear accumulation was observed. Analysis of a series of TIS11, fused to GFP showed that aa 1-101 is responsible for cytoplasmic location, and aa 88-161 is a functional NLS. However, the structure of the zinc figure is independent of the NLS function. TIS1-101 can export GFP from the nucleus, and upon LMB treatment, the fusion protein is distributed throughout both the cytoplasm and the nucleus. Deletion of aa 1-15 display a diffuse distribution, showing its necessity. The nuclear export activity of GFP1-161 was completely abrogated by L3A/I6A/L10A mutation.

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.
