Comments
Gwl (Mastl in mammals, entry #259) is a Cyclin B/Cdk1 activated kinase, which phosphorylates downstream proteins to regulate mitotic entry and progression. Wang et al. found that Drosophila Gwl is also shuttled to the cytosol in prophase in LMB-sensitive manner. In addition to two putative NLSs, a putative NES can be found in 553-558 (not the same as the ones tested in human Gwl). Kinase dead mutants K87R and S840A have abolished nuclear export activity. NES mutations that affected nuclear export did not affect kinase activity. This study also showed that phosphorylation of 562 and inactivation of the nearby NLS is required for nuclear exclusion.

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.
