The papers showed that muscle shortens by relative sliding between two sets of subcellular filaments containing the proteins myosin and actin.

Actomyosin is a protein complex composed of actin and myosin. It is found in muscle fibers where it plays a role in muscle contraction.

A muscle cell contains two sets of filaments composed of the proteins actin and myosin, respectively. Muscles contract as a result of the relative sliding of these filaments.

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 ...

In a remarkable scientific achievement, an international team has successfully obtained the world's first high-resolution 3D image of the thick filament in its natural cellular environment.

It had been thought that binding of actin filament consisting of skeletal muscles to myosin filament changed muscle structure and generated muscle contraction; however, how myosin filament used ...

The thick filament is formed of myosin, titin and myosin binding protein C (MyBP-C). The latter can form links between the filaments, whereas myosin, the so-called motor protein interacts with the ...

The cardiac thin filament governs contraction by sensing intracellular calcium levels, with conformational changes occurring at a threshold of pCa 6, enabling myosin-actin cross-bridge cycling and ...
