Myosin and kinesin: mother and child reunited.
The recent solution of the crystal structure of the kinesin motor domain reveals striking similarities to the core region of the myosin motor domain, implying a strong evolutionary relationship between these two motors. However, a complete understanding of the way that motility is generated will require additional structural information, which may explain how the two motors have adapted to their fundamentally different linear substrates, F-actin and microtubules.
