WebJan 3, 2024 · Figure 15.4. 3. Activation of mitotic cyclin/cdk complex. Using the mitotic cyclin/cdk complex as an example, the cyclin (cdc13) and cdk (cdc2) come together to form an inactive complex. The cdk is then phosphorylated by wee1, a kinase. The phosphate it puts on tyrosine-15 is needed for the rest of the activation sequence, but it is inhibitory ... WebMay 2, 2008 · Here, we show that p38 mitogen-activated protein kinase (MAPK) also inactivates GSK3beta by direct phosphorylation at its C terminus, and this inactivation can lead to an accumulation of beta-catenin. p38 MAPK-mediated phosphorylation of GSK3beta occurs primarily in the brain and thymocytes.

Phosphorylation Meets Proteolysis - ScienceDirect
WebPhosphorylation inactivates, whereas dephosphorylation activates, the pro-apoptotic functions of select apoptotic regulators, including the BCL2 family, such as BAD, and transcription factors such as FOXOs. The apoptotic function of the BH3 molecule BAD is exquisitely regulated by phosphorylation. WebIn contrast to p130, which is inactivated by phosphorylation via CDK4/6, pRB is activated by mono-phosphorylation via CDK4/6 and regulates activity of activator E2Fs induced at the G1/S boundary [14,37]. Cyclin E activates CDK2, which inactivates pRB by hyper-phosphorylation , further activating E2F, along with expression of activator E2Fs.
