Comments
Septin-2 protein is identified in proteomics study by Kirli et al. as a CRM1 binder. Human homolog functions as a filament-forming cytoskeletal GTPase. Export activity of xenopus Septin-2 is verified as GFP- and GFP-NLS-fusions in an LMB-sensitive manner but it appears to be weak. Purified protein can bind to mouse CRM1 in RanGTP-dependent manner weakly. Putative NES is identified in the C-terminal tail and tested to be active in GFP-NLS-NES fusion.

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.
