Some of the body's cells stay put for life, while others are free to roam. To move, these migratory cells rely on ...

filaments. The interaction of myosin and actin proteins is at the core of our current understanding of sarcomere shortening. How does this shortening happen? It has something to do with a sliding ...

Microtubules are the largest type of filament, with a diameter of about 25 nanometers (nm), and they are composed of a protein called tubulin. Actin filaments are the smallest type, with a ...

Scientists reveal how filopodia help cancer spread. The breakthrough could improve treatments that stop cancer cells from ...

It is our research goal to want to clarify variegated behavior of these the protein actin shows from the structure of the actin filament and the swing, and to deepen our protein understanding. The ...

In all eukaryotic cells, actin protein assembles to form a network of thin filaments that spread throughout the cell. The actin filaments give the cell its structure, enable the cell to move, and ...

Actin proteins group together to form a network of thin filaments that spread throughout a cell. This actin network is dynamic, meaning that the filaments can either grow or shrink to fit the ...

Actin is one of the most abundant proteins in eukaryotic cells. It exists primarily as monomers (G-actin) bound by G-actin binding proteins that prevent spontaneous nucleation of new actin filaments, ...

Actin, a family of proteins that help give cells their shape, are abundant throughout the body. F-actin forms filaments that are essential for maintaining cell structure and many other functions.

There, it uses a protein called ActA to recruit the host cell’s actin polymerization machinery to construct a tail of actin filaments behind it (3). This process gives the bacterium a means to propel ...
