The actin filament exists as a structure of the fixed length and bears the muscle contraction and the adjustment on a muscular inside. The circulation and the molecule movements of the polymerization ...

Microtubules are the largest type of filament, with a diameter of about 25 nanometers (nm), and they are composed of a protein called tubulin. Actin filaments are the smallest type, with a ...

Thin, flexible protein strands called actin filaments act like bones for our cells and are critical for its movement. Supercomputer simulations have helped solve a decades-old mystery of how actin ...
