During cell migration, the protrusive leading edge plays a key role in directional movement. The leading edge of migrating cells consists of two types of actin cytoskeletal architecture, lamellipodia and filopodia. Our research interest is the mechanism of unconventional myosins in cytoskeletal dynamics, i.e., lamellipodial localization of myosin-I, and filopodia formation by myosin-X. We use a combination of biochemical and molecular techniques, immunocytochemistry, and live cell-imaging techniques. Our goal is to understand a broad range of cell biological processes, including epithelial sheet closure in development, wound healing, neuronal path finding, immune cell function, cell invasion, and metastasis of cancer cells.
