Neurons migrate from proliferative zone to their final position during brain development. Cyclin-dependent kinase 5 (Cdk5) plays an important role in neuronal migration to establish a proper structure of the brain. Analyses of Cdk5/p35-deficient mice have provided the knowledge about the role of Cdk5/p35 in neuronal migration. Over the past years, migration-related substrates of Cdk5 have been identified. Imaging analyses of neuronal migration of Cdk5/p35-deficient neurons have begun to elucidate how proper phosphorylations of these proteins by Cdk5/p35 are required for the regulation of cytoskeletal dynamics and cellular adhesion during neuronal migration.
