Comments
Tomato HsfA2 is a strong heat stress-inducible protein. It is localized in the cytoplasm in spite of the presence of a functional NLS. Heerklotz et al. showed that this is due to the presence of a strong NES at the C-terminal (aa 339-351). When coexpressed with HsfA1, both proteins become nuclear. However, the molecular basis for this effect is not clear.

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.
