Regulated activity of the motor protein myosin in a cell

 

The inside of a cell is both incredibly crowded and highly organized. It is the organization within a cell that allows it to be an exciting environment capable of the functions associated with life. Important players in a cell’s ability to stay ordered are motor proteins. These microscopic engines allow a cell to transport, compartmentalize, and arrange its components by generating force and creating motion. In this talk, I will discuss work to understand how the motor protein myosin is regulated in a cell. I will highlight studies that span scales of size and complexity, from single motor studies of purified proteins (nm-scale) to investigations of the mechanical properties of muscle fibers (mm-scale), with a focus on how force regulates motor function.
