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 Although it is generally believed that phosphorylation of the regulatory light chain of myosin is required before smooth muscle can develop ...

"If actin is blocked, transcription can't begin," de Lanerolle said. The finding is published in the current issue of Nature Cell Biology and follows an earlier discovery by de Lanerolle and his ...

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 ...

Cell generated force plays essential roles in a wide range of biological processes, such as cell motility, cytokinesis, and tissue morphogenesis. In a study published in Nature Communications, a ...

The Fowler laboratory studies cellular architecture: how cells spatially organize themselves and their interior compartments to achieve intricate geometries, mechanical strength, and physiological ...

Researchers at the University of Cincinnati say a regulatory protein found in skeletal muscle fiber may play an important role in the body's fight or flight response when encountering stressful ...

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 ...
