Myosin in muscles behaves in a unique way, which might explain why muscles have such strong contractile power. A cartoon showing the asymmetry in the weak binding between myosin and actin that biases ...

The Burnham team, led by Dorit Hanein, Ph.D., was the first to reveal the 3D representation of myosin V "walking" along actin filament, a key protein involved in motility and muscle contraction.

Cells use the polymerization of actin alone to create some types of movement, but many other forms of movement require interplay between actin and an enzyme called myosin. Credit: extender_01 ...

We have adapted an actin-myosin motality assay to examine the interactions in vitro between actin cables isolated from the giant internodal cells of the freshwater alga, Nitella, and pigment granules ...

With genetic muscle diseases, the actin and myosin no longer work adequately together and the musculature is weakened as a result. It is not known why the proteins interact less effectively with each ...

As expected, PP1c was translocated to the cell membrane upon blue light illumination being exposed upon the OptoMYPT expressing cells, and consequently, actin and myosin-mediated contractile force ...

In a 2021 publication, the Max Planck researchers produced the first detailed 3D image of the sarcomere, the basic contractile unit of skeletal and heart muscle cell that contains actin, myosin and, ...
