Model showing the release of phosphate in different parts of the actin filament. Actin in the core of the filament has a closed door while the back door at the end of the filament is open. A mutation ...

An electron microscopy study revealed key details of actin filaments, which are essential structural elements of cells and muscles. Actin filaments -- protein structures critical to living movement ...

Actin is a highly abundant protein that controls the shape and movement of all our cells. Actin achieves this by assembling into filaments, one actin molecule at a time. The proteins of the formin ...
