Scientists have uncovered new details about cellular filaments that play a critical role in wound healing, according to a ...

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 ...

Space-filling model from molecular dynamics simulation showing actin filament barbed end (blue) and pointed end (red). Disclaimer: AAAS and EurekAlert! are not responsible for the accuracy of news ...

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 ...

The investigators noted that the "I band," rich in thinner filaments made of actin, changed its length along with the sarcomere. These observations led them to propose the sliding filament theory ...

one actin molecule at a time. The proteins of the formin family are pivotal partners in this process: positioned at the ...
