Comments
TFEB is a helix-loop-helix leucine-zipper transcription factor whose localization and thus activity is found to be regulated by phosphorylation in response to nutrient availability. Napolitano et al. and Li et al. both found TFEB to shuttle in the cell in a LMB-sensitive manner. A putative NES matching traditional consensus (first leucine is proline instead) can be found in residues 140-149. mTOR-dependent phosphorylation of S138 and S142, in close proximity to the NES, were found to be necessary for efficient export. Li et al. also mutated M146 and showed no affect on NES activity, showing that the proposed consensus match is correct. RanGTP-dependent CRM1 binding was illustrated by Li et al.

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.
