Actin filaments are protein fibers that make up the internal skeleton of the cell. As active elements of our cells, actin filaments support the cell’s fusion, movement and are involved in many other cellular processes. Importantly, they are also a major constituent of muscle cells. The structural complexity of these filaments has fascinated scientists since its discovery in the 1940s—and has opened a sea of unanswered questions behind their ability to facilitate many processes of the cell.
