Dynamic electron microscopy: recording of ATP-induced myosin head movement in living muscle myosin filament

Muscle contraction results from relative sliding between actin and myosin filaments, caused by cyclic movement of myosin heads coupled with ATP hydrolysis. It is generally believed that individual myosin heads M), extending from myosin filaments, first bind

Gamma-tubules — novel filaments in the fight against cancer

The word skeleton sounds very significant, and indeed humans could not exist without a skeleton! Similarly, a cellular skeleton or cytoskeleton is crucial for the functions of a cell. Several different types of cytoskeleton have been identified

How cells crawl… that’s right, crawl

Within our bodies, every cell must crawl – some only a few millionths of an inch, while others, like nerve fibers, must make their way from the spinal cord to the tips of our toes. The ability
