Comments
NPAS4 is class I bHLH- PAS transcription factor. Previous work has shown that the protein is exclusively nuclear, but Greb-Markiewicz et al. showed that the protein shuttles in COS-7 and Neuro 2a (N2a) cells at 24 hrs before becoming predominantly nuclear after 48 hours. Using truncations of the protein, the authors identified multiple putative NLSs and NESs in the N-terminal bHLH domain, the PAS-2 domain and the C-terminus. Residues 461-580 in the C-terminus also displayed LMB-sensitive export activity that appears to be masked by inclusion of residues 341-460, however no putative NESs was be identified. It should be noted that activity of these mutants in full-length protein was not tested. Regions of NLS and NES detected are highly conserved with human NPAS4.

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.
