CDK5 is a proline-directed serine/threonine kinase that requires association with regulatory subunits p35 or p39 for activity. The kinase domain shares homology with other CDKs but has unique structural features that determine its neuronal specificity.
CDK5 is critical for neuronal development and function. It regulates neuronal migration, axonal guidance, synapse formation, and plasticity. CDK5 phosphorylates numerous substrates including tau, synapsin, NMDA and AMPA receptor subunits, and transcription factors. It is essential for learning and memory.
Dysregulated CDK5 activity contributes to neurodegeneration. In AD, CDK5 hyperphosphorylates tau and is activated by A-beta. In PD, CDK5 can phosphorylate alpha-synuclein and contribute to dopaminergic neuron death. In ALS, CDK5 is involved in motor neuron degeneration. p25 accumulation (truncated p35) leads to CDK5 hyperactivation in neurodegeneration.
CDK5 inhibitors have been explored but face challenges due to its essential functions. Roscovitine (seliciclib) inhibits CDK5 among other CDKs. Peptide inhibitors targeting CDK5-p25 interaction are in development.Gene therapy approaches to reduce p25 are being investigated.
