They play a leading role not only in muscle cells: Actin filaments are one of the most abundant proteins in all mammalian cells. The filigree structures form an important part of the cytoskeleton and locomotor system. Cell ...

When a muscle is activated, it is the proteins myosin and actin that go to work. Myosin molecules take hold of actin molecules and pull, like rope pulling, in a process that gets energy from the use of the cellular fuel ATP. ...
