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

one actin molecule at a time. The proteins of the formin family are pivotal partners in this process: positioned at the filament end, formins recruit new actin subunits and stay associated with ...

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 ...

The authors point out that, in low concentrations of ATP, when the myosin heads both remain bound to the actin filament, the molecule often seems to be straining forward, in the form of a ...

Their work, published in Nature Communications, reveals a mechanism of interdependence of different forms of the cytoskeletal proteins actin and myosin, and their functions. The team also ...
