It was first discovered in skeletal muscle, where actin filaments slide along filaments of another protein called myosin to make the cells contract. (In nonmuscle cells, actin filaments are less ...

Physicists from the Universities of Bayreuth and Grenoble have discovered a new mechanism of cell mobility. Their findings ...

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 ...

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 ...

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 ...

The movement of cells in the human body – known as cell migration – is crucial for immune cells. These cells must move quickly and flexibly in different environments in order to fulfil their role as ...

The biconcave disk shape and deformability of mammalian red blood cells (RBCs) rely upon the membrane skeleton, a viscoelastic network of short actin filaments interconnected ... from other ...

as actin building blocks are either added to or removed from the ends of filaments. According to the classical model, the generation of cell movement also requires the molecular motor myosin.
