Web3 de mai. de 2024 · The activity of CDKs can be tightly controlled by phosphorylation and dephosphorylation of two specific residues on the protein. Phosphorylation of the 15 th amino acid residue, a tyrosine (written as Tyr 15) deactivates CDK2, while phosphorylation of the Thr 160 residues activates the CDK. WebMPF provides a good example of how cyclins and Cdks can work together to drive a cell cycle transition.
