Cofilin plays an essential role in regulating actin filament propagation through the cytoplasmic medium. Over the years, various studies have been conducted in an attempt to better understand the complex mechanism by which cofilin promotes filament severing and de-polymerization. Here, we have compiled information obtained from these studies in order to craft a more complete and succinct description of cofilin functionality. In particular, we review the precise structural and mechanical changes associated with cofilin-binding, and the subtle ways in which some of these structural changes may be interconnected.
