General description
Research area: Apoptosis
Cdk5 is a proline-directed serine/threonine protein kinase that belongs to the family of cyclin-dependent kinases (CDKs). Active CDK5, also known as neuronal cdc2-like kinase is a heterodimer of CDK5 and is essential for its kinase activity. They are found abundantly in the mammalian brain.
Application
CDK5 has been used as a component of a buffer during the measurement of the in vitro phosphorylation of peroxisome proliferator-activated receptor gamma (PPARγ).
Biochem/physiol Actions
CDK5 is a neuron-specific kinase that plays a vital role in the development, functioning, and diseases of the central nervous system. Its optimum functioning is highly essential for proper neuronal migration, differentiation, axonal elongation, and synaptic function. CDK5 modulates neurite outgrowth, and axonal growth by interacting with several substrates like N- cadherin, Rap Guanine Nucleotide Exchange Factor 2(RapGEF2), focal adhesion kinase (FAK), p21 activating kinase 1, serotonin 6 receptor and Ras-related protein 8. CDK5 also plays a key role in the formation of the synapse, its maintenance, and communication. It is involved in the formation and retraction of the dendritic spines. It also regulates neuron secretion at the synapse by phosphorylating key mediators such as Synaspsin1. In addition, CDK5, present in the synaptic membrane phosphorylates the erythroblastic leukemia viral oncogene homolog B receptor (ErbB), resulting in increased acetylcholine receptor transcription. Lastly, CDK5 is also involved in the regulation of various other cellular processes like cell cycle, cell survival, apoptosis, gene regulation, etc.
