WebDuring the specialized divisions of meiosis, the activity of the APC/C must be modified to achieve proper chromosome segregation. Recent studies show that one way in which APC/C activity is modified is through the use of meiosis-specific APC/C activators. Furthermore, regulation of the APC/C during meiosis is carried out by both mitotic ... 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.
