This kinase is activated by the non-cyclin … WebCDKs are activated by binding to a cyclin; each CDK has minimal kinase activity when unbound. The exact structural changes that occur upon cyclin binding vary for different CDKs. Cyclin A binding to CDK2 occurs at both the N- and C-lobes of CDK2, whereas interactions between CDK4 and cyclin D are limited to the N-lobe.

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).
