Comments
CDC27 is a E3 ubiquitin ligase of the anaphase promoting complex/cyclosome (APC/C) which controls mitotic progression. A putative reverse NESs was identified by in silico prediction methods in Sendino et al. using possible XPO1/CRM1-cancer exportome proteins identified previously as putative CRM1-binders by Kirli et al. (not all proteins were validated in full-length). This NESs was tested using Rev(1.4)-GFP assay which showed weak activity. It however did not show response in SRVB/A reporter with co-expression with CRM1, and therefore, no CRM1-dependency has been clearly demonstrated. This NES forms an alpha-helix as part of a helical domain and is buried in the center of the APC/C complex and is likely not a real 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.
