Comments
USP12 is a member of the human deubiquitinase family. Jahan et al. found USP12 to be exported to the cytosol upon T-cell receptor stimulation. This can be abolished by LMB treatment or mutations to a putative NES in residue 77-99. This region matched non-canonical class 3 NES consensus. García-Santisteban et al. also tested another putative NES in 248-262 in isolation fused to a fluorescence reporter and found no export activity. Olazabal-Herrero et al. showed LMB sensitivity of USP12 localization, but the previously identified NES from Jahan et al. was not active in a nuclear export assay in a Rev(1.4)-GFP reporter. Mutations to the NES region instead disrupted interaction with WDR20 which the authors found to have a functional NES instead (entry #404).

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.
