Cdk5 Directly Targets Nuclear p21CIP1 and Promotes Cancer Cell Growth
30 Nov 2016
Abstract excerpt
Abstract The significance of Cdk5 in cell-cycle control and cancer biology has gained increased attention. Here we report the inverse correlation between the protein levels of Cdk5 and p21CIP1 from cell-based and clinical analysis. Mechanistically, we identify that Cdk5 overexpression triggers the proteasome-dependent degradation of p21CIP1 through a S130 phosphorylation in a Cdk2-independent manner. Besides, the...
