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 ...

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

Research has uncovered how motor protein myosin, which is responsible for contraction of skeletal muscles, functions also in non-muscle cells to build contractile structures at the inner face of the ...

The standard textbook model of muscle contraction includes only two main players, the filaments actin and myosin, which slide past each other, causing the sarcomere—the basic unit of muscle tissue—to ...

Muscles are made up of proteins. Myosin, a fibrous protein, serves as a molecular motor and converts the chemical energy stored inside our body into mechanical energy. The synergistic association ...
