The myosin 2 family of molecular motors includes isoforms regulated in different ways. Vertebrate smooth-muscle myosin is activated by phosphorylation of the regulatory light chain, whereas scallop ...

Molecular motors are nanomachines that convert chemical energy to mechanical work for unidirectional movement. Actomyosin motors have been extensively studied over more than half a century, as ...

A visualization made from nearly 100,000 electron microscope images has revealed the ingenious way a protein involved in muscle activity shuts itself down to conserve energy. The protein is called ...

The results discussed in the preceding paper indicate that A-band shortening in Limulus muscle is a thick filament response to activation that occurs largely by fragmentation of filament ends. To ...

In a decades-long effort, researchers have discovered how to tweak the molecular pathways that turn heart muscle motors up or ...

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 ...
