Dynein

Dynein:

 A molecular motor, a complex believed to be made of 12 distinct protein parts, that performs basic transportation tasks critical to the cell. Converts chemical energy stored in an ATP (adenosine triphosphate) molecule into mechanical energy that moves material
through the cell along slender filaments called microtubules.
One of the most important functions occurs during cell division, when it helps move chromosomes into proper position. It also plays a part in the movement of eukaryotic flagella and cilia.
Molecular motors play a critical role in a host of cell functions such as membrane trafficking and cell movement during interphase, and for cell asymmetry development. During cell division, they are responsible for establishing the mitotic or meiotic spindle, as well
as segregating chromosomes and dividing the cell at cytokinesis. It is the last part of the mitotic cycle, during which the two daughter cells separate. Motors either move along actin tracks (members of the myosin superfamily) or microtubules (the dynein and kinesin
superfamilies). Based on the Greek dunamis, meaning power.
