The cytoskeleton is made up of three kinds of protein filaments: Actin filaments (also called microfilaments); Intermediate filaments and; Microtubules.
They are polymers of actin subunits (globular actin, or G-actin), which as part of the fiber are referred to as filamentous actin, or F-actin. Each microfilament is made up of two helical, interlaced strands of subunits. Much like microtubules, actin filaments are polarized.
