Molecular motor proteins are fascinating enzymes that power much of the movement performed by living organisms. In this introductory lecture, I will provide an overview of the motors that move along cytoskeletal tracks (kinesin and dynein which move along microtubules and myosin which moves along actin). The talk first describes the broad spectrum of biological roles that kinesin, dynein and myosin play in cells. The talk then discusses how these nanoscale proteins convert energy from ATP hydrolysis into unidirectional motion and force production, and compares common principles of kinesin and myosin. The talk concludes by discussing the role of motor proteins in disease and how drugs that modulate motor protein activity can treat human disease.
Part 2 discusses recent work from the Vale laboratory and other groups, on the mechanism of movement by dynein, a microtubule motor that is less well understood than kinesin and myosin. The lecture d
