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 ...

Scientists are bringing the basis of muscle movement into sharper focus. Muscle contraction and many other movement processes are controlled by the interplay between myosin and actin filaments. Two ...

This is a preview. Log in through your library . Abstract Although it is generally believed that phosphorylation of the regulatory light chain of myosin is required before smooth muscle can develop ...

The Journal of Cell Biology (JCB) is a not-for-profit publication, edited by scientists, and a leading life sciences journal. The JCB publishes papers on all aspects of cellular structure and function ...

Some cells, such as immune cells, are highly mobile—they constantly remodel their shape, migrate toward a wound that needs to ...

A review paper by scientists at the University of Oxford highlights recent advancements in SMTE, including innovations in ...

When a muscle contracts, the parts of a sarcomere "shorten" and come closer together. Each cardiac muscle cell can have over 5,000 sarcomeres, which compounds both the shortening and relaxation events ...

Muscle contraction is the tightening, shortening, or lengthening of muscles when you do some activity. It can happen when you hold or pick up something, or when you stretch or exercise with weights.

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 ...
