How is mitosis regulated
Web9 jul. 2007 · At mitotic entry, Plk1 phosphorylates Ser 198, inhibiting Cdc25C-14-3-3 binding, allowing for localization of Cdc25C to the nucleus where it can dephosphorylate and activate Cdk1/cyclin B1. Before entering mitosis, Cdk1/cyclin B1 is in an inactive state by phosphorylation of Thr 14 and Tyr 15. Activation of Cdk1/cyclin B1 occurs in steps.
