CDK means Cyclin Dependent Kinase. The cyclin-dependent kinases (CDKs) are a large family of serine–threonine kinases which control the eukaryotic cell cycle, when they are activated by the cyclin regulatory subunit. These kinases phosphorylate a very large number of protein in order to inactivate or activate them.^[1] Cyclin dependent kinase 5 (CDK5) is a unique member of CDK family members that is not activated by a cyclin. Instead it is activated by a kinase, p35 also named Cyclin-dependent kinase 5 activator. Unlike other CDKs, it plays a major role in cell communication, cell morphology and motility.

CDK5 could form a complex with p25, an other protein.

Structure

Sequence similarities

The chains A and B of the CDK5-p25 complex share homologuous sequences with the cell division protein kinase 5 and the chains D and E with the cyclin-dependent kinase 5 activator (p35).

The subunit of the CDK5 shares also a very similar three-dimensional (3D) structure with CDK2.
