Cdks are the catalytic subunits of serine/threonine protein kinases which are involved in the progression through the cell cycle. Despite its high degree of homology to other cyclin-dependent kinases, Cdk5 is not activated by cyclins and there is no indication for a role in cell cycle regulation. The formation of a functional holoenzyme results upon interaction with activators p35, p39, p25 and p29. Cdk5 is expressed in all tissues, but its highest expression and activity is present in postmitotic neurons. Activated CDK5 is involved in several processes including neuronal migration, neurotransmitter release, neuronal plasticity, memory, learning, addiction, and apoptosis. Aberrant Cdk5 activity induced by the conversion of p35 to p25 plays roles in the pathogenesis of neurodegenerative diseases.
