| Research Abstract |
Myosin 6 is the only myosin among myosin superfamily that moves to the minus end of actin filament. Interestingly, it is known that myosin 6 walks with larger stride than that expected from their foot length. However, their functional mechanism has not been elucidated yet, due to the lack of structural evidence. Here, we performed high-speed atomic force microscopy to directly observe their structural dynamics of myosin 6 at work. Then, the structural evidence was successively obtained for the first time, leading to better understanding the functional mechanism of myosin 6.
