Comments
Nup214 is a component of the nuclear pore on the cytoplasmic side. It is known to interact with CRM1 through FG-repeats on its C-terminal region, which recruits CRM1-Ran-cargo complexes to the nuclear pore and stabilizes the export complex (Port et al.). Hamed et al. identified a classic NES (residues 875-887, class 1a match) using LocNES algorithm. LMB treatment causes mislocalization of exogenous and some endogenous Nup214 to the nucleus, which is normally enriched in the nuclear rim. Prolonged LMB treatment also causes mislocalization of Nup88, which makes up the Nup214-Nup88-Nup62 subcomplex. The NES is shown to be active in cells and bind CRM1 in a Ran-dependent manner in vitro, in a RanGAP1-induced Ran-hydrolysis protection assay, size-exclusion chromatography using synthetic peptide in its isolated form, as well as in pull-down binding assays within larger fragments of Nup214. The measured binding affinity of the NES is tighter than that of PKI or HIV Rev. Leucine mutations to the NES rendered the NES inactive in vitro and in vivo, in isolated form and within larger fragment of or full-length Nup214. The NES is located in a putative coiled-coil region thought to interact with Nup88, but leucine mutations did not abolish Nup88 binding and did not interfere with incorporation of Nup88 and itself into the NPC. Hamed et al. suggest that this NES may be important for ensuring cytoplasmic localization of Nup214 and NPC-biogenesis, as well as supporting the dissociation of some CRM1-cargo complexes by competition.

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.
