Cdk5 Activator

Recently Cdk5 has emerged as an important kinase in the nervous system. Recent reports made by Pareek et al. raise its need for pain relief. CDK5 is required for brain development and functioning, CDK5 must interact with CDK5R1 or CDK5R2. Unlike other cyclin-dependent cycles, CDK5 does not require phosphorylation in the T loop so that binding with the activator is sufficient to activate the kinase. Cdk5 is involved in the processes of neuronal maturation and migration, phosphorylating the intracellular adapter key of the reelin signaling chain. Experiments conducted in mice lacking p35 (CDK5R1), a required activator of cdk5 in early brain development, showed that normal formation of neurons returned to the border. This upregulation also interferes with cdk5 in neuronal migration and plasticity. Cdk5 is also involved in the regulation of synaptic vesicle exocytosis by phosphorylation of munc-18.
