ac·tin

 (ăk′tĭn)
n.
A protein that forms the microfilaments of the eukaryotic cytoskeleton and plays an important role in cell movement, shape, and internal organization. In muscle cells, it functions with myosin to produce contraction.

Recognizing that a single volume could never cover the breadth of recent research into the cytoskeleton, medical and biological researchers provide snapshots that capture the basic properties of each of the three major cytoskeletal systems: actins, intermediate filaments, and microtubules.
The Cytoskeleton
The project leader Prof Inari Kursula said that the structures showed them that the two variants differ more from each other than actins in any other known living organism do and the high resolution enabled the researchers to identify areas within the proteins that cause the different behaviour.
