Abstract

Over the past decade, a remarkable number and diversity of molecular motors have been described in eukaryotic cells. In addition to the identification of novel forms of myosin and dynein, the kinesins have been defined as an entirely new family of molecular motors. There may be as many as 30 different genes in a single organism encoding members of the kinesin superfamily. Why is such diversity in molecular motors needed? The biochemical and functional diversity of the originally defined form of kinesin provides some insights into the roles of molecular motors in cellular dynamics.
