WebThe activity of CKIs represents an additional layer of cell-cycle regulation over and above that mediated by temporal cyclin synthesis and degradation. Cancer cells typically lose cell cycle entry control. Explain how the following mutations, which are found in some cancer cells, lead to a bypass of these controls: (a) overexpression of cyclin ... WebCyclin synthesis is gradual, yet activation of Cdk1 occurs in a stepwise manner: a low level of Cdk1 activity is initially generated that triggers early mitotic events, which is followed by full activation of Cdk1. Little is known about how stepwise activation of Cdk1 is achieved. A key regulator of Cdk1 is the Wee1 kinase, which phosphorylates ...
