The cytoskeleton is made up of three kinds of protein filaments: Actin filaments (also called microfilaments); Intermediate filaments and; Microtubules.
The filaments also enable a dividing cell to pinch off into two cells and are involved in amoeboid movements of certain types of cells. Microfilaments are solid rods made of a protein known as actin. When it is first produced by the cell, actin appears in a globular form (G-actin; see Figure 1).
