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 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 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 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 ...

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 ...

A recently identified bacterial protein structure is contributing to the design of novel anticancer drug delivery systems.

Our skin and mucous membranes are protected by epithelial cells. This barrier tissue performs its function thanks to specialized structures called junctions. They ensure cell cohesion and regulate ...
