Motor protein structure

Definition

Motor protein structure describes the structure of molecular motors capable of moving along a cytoskeletal filament. In many cases, motor proteins transport cargo in a particular direction along the filament, and this directionality is associated with both protein and filament structure.

    The detailed mechanism by which the molecular motors kinesin and myosin travel along their respective protein tracks as they generate force during motile processes is still poorly understood. In a recent breakthrough, a crystal structure of kinesin in complex with tubulin illuminates the atomic-level details of a motor-track interaction, answering many questions yet leaving a number of mysteries unresolved.
