Cg. Takizawa et Do. Morgan, Control of mitosis by changes in the subcellular location of cyclin-B1-Cdkw and Cdc25C, CURR OP CEL, 12(6), 2000, pp. 658-665
Nuclear events of mitosis are initiated when the protein kinase cyclin-B1-C
dk1 is translocated into the nucleus during prophase. Recent work has unvei
led many of the mechanisms that govern the localization of cyclin-B1-Cdk1 a
nd its regulator Cdc25C. Phosphorylation-dependent changes in the rate of n
uclear import and export of these proteins help to control the onset of mit
osis both in normal cells and in cells delayed before mitosis by DNA damage
