CDK1 (cyclin-dependent kinase 1), also known as the cell division cycle protein 2 homolog and CDC28, is a key player in cell cycle regulation and a member of the CDK family which is characterized by the need for a separate subunit-cyclin providing the domains necessary for enzymatic activity. Like other cyclin-dependent kinases, CDK1 contains a T-loop that prevents binding of the substrate to the CDK1 active site in the absence of interacting cyclins. There’re several important amino acid side chains in the C-loop leaves, however, the active site is not properly positioned, which makes the orientation of the ATP phosphate to the kinase reaction poor. CDK1 also contains a PSTAIRE helix that moves and rearranges the active site after cyclin binding, thereby promoting CDK1 kinase activity.
The activity of CDK1 is regulated by its binding to the cyclin partner. In addition, CDK1 is regulated by phosphorylation. The phosphorylation of conservative tyrosine (Tyr15 in humans) alters the direction of ATP and prevents potent kinase activity leading to inhibition of CDK1. The Cdk1-cyclin complex is also controlled by the direct binding of CDK inhibitory protein (CKI).
Functionally, CdK1/2 inhibition has the most effective stage of action during S and G 2 and induces E2F transcription factor-dependent cell death. Regulation of CDK1 activity also affects survival checkpoint responses after exposure to DNA damage and microtubule stabilizers. Studies have shown various genetic and epigenetic events lead to widespread over-activity of cell cycle CDKs in human cancers, and their inhibition can lead to cell cycle arrest and apoptosis. Due to the critical role of CDK1 in cell cycle progression and cell transcription, and their relationship to the apoptotic pathway, CDK1 constitutes an attractive target for the development of novel anticancer drugs.
