Comments
SPN90/NckIPSD is a regulator of actin polymerization. This NES 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 putative NES peptide was tested using Rev(1.4)-GFP and SRVB/A reporters based on replacing survivin NES and with other peptide sequences. CRM1-dependency is illustrated by cytoplasmic accumulation of the reporter when co-expressed with CRM1. The export activity of this NES is weak.

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.
