Video imaging of walking myosin V by high-speed atomic force microscopy.
2010
High-speed atomic force microscopy can be used to record the structure and dynamics of biomolecules simultaneously. These authors use this method to directly observe the dynamics of the motor protein myosin V moving along actin filaments, with unprecedented time resolution. The high-resolution movies provide evidence supporting the 'swinging lever-arm' model of myosin motility, and provide important insights into the mechanism of motor movement.
