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

Actin is the most abundant protein in eukaryotic cells, at cellular concentrations generally above 100 mM. This abundance has made actin a focus of biochemical research since its identification by ...

actin filaments are rapidly polymerizing; at its rear edge, they are quickly depolymerizing (Figure 5). A large number of other proteins participate in actin assembly and disassembly as well.
