CELL CYCLE Getting Out of Mitosis

The protein phosphatase Cdc14 controls a number of the late events of mitosis. Cdc14 is sequestered in the nucleolus, but late in mitosis, it is released and moves throughout the cell to help to coordinate the exit from mitosis. Cdc14 is held in the nucleus through interaction with a protein called Net1. Azzam et al. show that release of Cdc14 appears to depend on phosphorylation of Net1 by the master regulator of mitosis, the complex of cyclin B and cyclin-dependent kinase.
