| Research Abstract |
Nuclear translocation of migrating neurons is prerequisite for the formation of functional brain circuits, but its molecular mechanism has remained unclear. In this study, I focused on dynamics of the cytoskeleton, which is closely related to nuclear dynamics, and successfully obtained high-resolution time-lapse images of nuclear and cytoskeletal dynamics during nuclear translocation, simultaneously. In addition, we investigated the roles of several cytoskeletal and nuclear proteins for neuronal migration (and nuclear translocation) and I reported that CDK5, a kinase regulating many cytoskeletal proteins, differentially regulates two types of migration of cerebellar granule neurons. This study is expected to help our understanding of neuronal disorders associated with neuronal migration defects.
