Comments
Dsk1 is a S. Pombe protein kinase acting on splicing factors. During interphase, it localizes in the cytoplasm. Previous works showed that a mutant Dsk1 lacking residues 228-352 localizes to both the nucleus and the cytoplasm. Fukuda et al. demonstrated that a putative NES sequence (aa 308-320), when conjugated to OV, was found to be completely excluded from the nucleus, after being injected into the nucleus. They also reported that Dsk localized to both the cytoplasm and the nucleus in the presence of LMB.

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.
