Job of microfilaments
WebMicrofilaments are the thinnest part of the cytoskeleton, and are made of actin [a highly-conserved protein that is actually the most abundant protein in most eukaryotic cells]. Actin is both flexible and strong, making it a useful protein in cell movement. In the heart, … WebMicrofilaments play important roles in changing the shape of cells. When a cell divides, a ring of actin, working in concert with myosin molecules, constricts the dividing cell so that ultimately it forms a narrow waist, which ultimately completely breaks the connections between the two daughter cells.
