RegulationofcellcycleprogressionbyPlk3
The focus of this pathway is to illustrate the role of Polo-like Kinase 3 (Plk3 also known as Prk and Fnk) as part of the regulatory cascade leading to apoptosis and the arrest cell cycle progression prior to M phase. Phosphorlyation of Cdc25C on serine-216 causes the arrest of the cell cycle at the G2/M phase border by preventing Cdc25C from activating cyclinB1/Cdk1. Xie et al. demonstrated that Plk3 like Chk1 and C......阅读全文
