Abstract:
Cyclin-dependent kinase 5 (CDK5) plays an essential role in the development of the central nervous system during mammalian embryogenesis. In the adult, CDK5 is required for the maintenance of neuronal architecture. Its deregulation has profound cytotoxic effects and has been implicated in the development of neurodegenerative diseases such as Alzheimer's disease and amyotrophic lateral sclerosis. In this review, we concentrate on the regulation of CDK5 activity, privileging a structural perspective based on a decade of structural analyses of different members of the CDK family, including CDK2 and CDK5. We review the activation mechanism of CDK5 and discuss its differences and similarities with that of CDK2 and of the other members of the CDK family.

M-Cdk Drives Transition Into Mitosis
Cyclin-dependent kinases, or Cdks, work in concert with cyclins to control cell cycle transitions. M-Cdk, a complex of Cdk1 bound to M cyclin, is a well-known example of this coordinated control that drives the transition from the G2 to the M phase.
