Comments
CEP43 functions in anchoring microtubules to centrosomes. Two putative NESs (classical NES: 352-370 and reverse NES: 379-397) were 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). These putative NESs were tested using Rev(1.4)-GFP assay which all showed weak activity. Only 352-370 was tested in SRVB/A reporter with co-expression with CRM1, and showed no change in localization. Therefore, no CRM1-dependency has been demonstrated for any of the NESs.

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.
