Comments
PEDV Nucleoprotein is a multifunctional protein which is critical for the survival of the positive-sense RNA virus of the Coronaviridae family. Shi et al. found that N can be found predominantly in the cytoplasm but can also be found in the nucleus (or nucleolus) of infected cells. Transiently transfected cells with over-expression of N also showed cytoplasmic localization that is LMB sensitive. Analysis of the localization of GFP fused to N fragments revealed region 221-236 to contain a putative NES, however deletion of the region did not affect localization of full-length protein. Conversely, while 325-364 showed LMB-sensitive export activity, deletion of region 325-364 was not tested in context of full-length protein. This region is part of the dimerization domain. It is unclear if this putative NES will be accessible for CRM1 binding.

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.
