Comments
Zo-2 contains four NESs. Each has been shown to export reporter proteins in LMB sensitive manner. Single mutation at each NES can induce a strong nuclear accumulation of full-length ZO-2. Apparently, phosphorylation of Ser369 is required for NES at 361-370 to be functional.

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.
