Human Cdc14A reverses CDK1 phosphorylation of Cdc25A on serines 115 and 320.

Human Cdc14A is an evolutionary conserved dual-specificity protein phosphatase that reverses the modifications effected by cyclin-dependent kinases and plays an important role in centrosome duplication and mitotic regulation. Few substrates of Cdc14A have been identified, some of them with homologues in yeast that, in turn, are substrates of the Saccharomyces cerevisiae Cdc14 homologue, a prote...

Human Cdc14A Phosphatase Modulates the G2/M Transition through Cdc25A and Cdc25B*

The Cdc14 family of serine-threonine phosphatases antagonizes CDK activity by reversing CDK-dependent phosphorylation events. It is well established that the yeast members of this family bring about the M/G1 transition. Budding yeast Cdc14 is essential for CDK inactivation at the end of mitosis and fission yeast Cdc14 homologue Flp1/Clp1 down-regulates Cdc25 to ensure the inactivation of mitoti...

Human Cdc14A regulates Wee1 stability by counteracting CDK-mediated phosphorylation

The activity of Cdk1-cyclin B1 mitotic complexes is regulated by the balance between the counteracting activities of Wee1/Myt1 kinases and Cdc25 phosphatases. These kinases and phosphatases must be strictly regulated to ensure proper mitotic timing. One masterpiece of this regulatory network is Cdk1, which promotes Cdc25 activity and suppresses inhibitory Wee1/Myt1 kinases through direct phosph...

Regulation of sororin by Cdk1-mediated phosphorylation.

Tumor cells are commonly aneuploid, a condition contributing to cancer progression and drug resistance. Understanding how chromatids are linked and separated at the appropriate time will help uncover the basis of aneuploidy and will shed light on the behavior of tumor cells. Cohesion of sister chromatids is maintained by the multi-protein complex cohesin, consisting of Smc1, Smc3, Scc1 and Scc3...

Phosphorylation by Cdk1 induces Plk1-mediated vimentin phosphorylation during mitosis

Several kinases phosphorylate vimentin, the most common intermediate filament protein, in mitosis. Aurora-B and Rho-kinase regulate vimentin filament separation through the cleavage furrow-specific vimentin phosphorylation. Cdk1 also phosphorylates vimentin from prometaphase to metaphase, but its significance has remained unknown. Here we demonstrated a direct interaction between Plk1 and vimen...
