Comments
Greatwall is a protein kinase that inhibits PP2A phosphatases, thus maintaining the mitotic state of cell cycle. Alvarez-Fernandez et al. demonstrated that greatwall is a shuttling protein. During interphase, greatwall is nuclear. Then following the nuclear import of cyclin B-Cdk1 complexes, it is exported to the cytoplasm before nuclear envelope breakdown.

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.
