The sliding filament model, proposed to explain muscle contraction in 1954, has proven to be very robust. Muscle contraction as well as much of the motility of nonmuscle cells has now been shown to be ...

Prior to the sliding filament model, the most popular theories held that contraction was produced by the shortening of some large, rubber-like polymers. Since 1954, the motor that produced filament ...

Dynamic actin filament assembly and turnover underlie diverse biological processes, such as cell motility, adhesion formation and vesicular trafficking 1. However, in certain differentiated and ...
