Actomyosin is a protein complex composed of actin and myosin. It is found in muscle fibers where it plays a role in muscle contraction. Actin is one of the most abundant proteins in eukaryotes. It ...

Actin, a protein with a well-known job in the cytoplasm and an active role in muscle contraction, moonlights in the nucleus. It's function there was not understood, but now scientists find that it ...

At the molecular level, muscle contraction is defined by myosin molecules pulling actin filaments. New electron cryomicroscopy images with unprecedented resolution taken by researchers at Osaka ...

This is a preview. Log in through your library . Abstract F-actin in a glycerinated muscle fiber was specifically labeled with fluorescent phalloidin-(fluorescein isothiocyanate) FITC complex at 1:1 ...

A team of Yale and University of Pennsylvania researchers recently discovered that myosin, one of the proteins responsible for muscle contraction, can sense and adapt to different amounts of force.

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 ...

Living cells are highly organized, yet they are not assembled using rigid blueprints or by following a predetermined plan.

Understanding how microscopic interactions between proteins in cells produce large-scale organization and asymmetry is a fundamental question in cell biology.

Living cells are highly organized, yet they are not assembled using rigid blueprints or by following a predetermined plan. Instead, order emerges on ...

Atomic images of muscle molecules in action have now been captured by researchers, giving possibility of new nanomachines. At the molecular level, muscle contraction is defined by myosin molecules ...
