Cdk phosphorylation
WebCDK substrate phosphorylation was analyzed during the cell cycle. (A) Schematic of experimental design: a light labeled culture (MS230) was released from G2 arrest and protein samples were recovered at 20 time … CDK levels remain relatively constant throughout the cell cycle and most regulation is post-translational. Most knowledge of CDK structure and function is based on CDKs of S. pombe (Cdc2), S. cerevisiae (CDC28), and vertebrates (CDC2 and CDK2). The four major mechanisms of CDK regulation are cyclin binding, CAK phosphorylation, regulatory inhibitory phosphorylation, and bindin…

WebTo dephosphorylate CDK substrates, cells were incubated at different stages of the cell cycle with the 1-NmPP1 inhibitor. Following inhibitor washout, the in vivo rate of CDK phosphorylation was measured, and was shown to increase by 50-100 fold during the cell cycle, illustrating the huge dynamic range of the kinase. WebDec 15, 2016 · Here, we present a phosphoproteomics-based systems analysis of CDK substrates in fission yeast and demonstrate that the phosphorylation of different CDK substrates can be temporally ordered during the cell cycle by a single cyclin-CDK. This is …
