Comments
C-terminal NES - located in the tetramerization domain 326-356; NES mutations decrease tetramerization; NES masked in tetramer. NES unmasked by protein-protein interactions (ARC) and/or post-translation modifications (phosphorylation, MDM2/ubiquitination, ADPribosylation) that convert tetramer to dimer or monomer. N-terminal NES - Zhang et al 2001 Science (PMID: 11397945) suggested that C-terminal NES is insufficient, and residues 11-27 are also required for nuclear export. Residues 11-27 may be an N-terminal NES.

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.
