CDK

CDK

CDKs (Cyclin-dependent kinases) are serine-threonine kinases first discovered for their role in regulating the cell cycle.Additionally, they control mRNA processing, transcription, and nerve cell differentiation. With molecular weights between 34 and 40 kDa, CDKs are relatively small proteins that only contain the kinase domain. In fact, when their CDK gene has been replaced with the homologous human gene, yeast cells can proliferate normally. A CDK by definition binds the control protein cyclin. Only the cyclin-CDK complex is an active kinase; CDK lacks much kinase activity on its own.

Around 20 Cyclin-dependent kinases (CDK1-20) have been identified as of yet. While CDK 7, 8, 9 and 11 are linked to transcription, CDK1, 4, and 5 are involved in the cell cycle.

The majority of CDK regulation occurs post-translationally, and CDK levels are essentially constant throughout the cell cycle. The majority of knowledge about CDK structure and function is based on CDKs from vertebrates (CDC2 and CDK2), S. pombe (CDC28), and S. cerevisiae (Cdc2). Cyclin binding, CAK phosphorylation, regulatory inhibitory phosphorylation, and CDK inhibitory subunit (CKI) binding are the four main mechanisms of CDK regulation.
