<P> An actin protein is the monomeric subunit of two types of filaments in cells : microfilaments , one of the three major components of the cytoskeleton , and thin filaments , part of the contractile apparatus in muscle cells . It can be present as either a free monomer called G - actin ( globular ) or as part of a linear polymer microfilament called F - actin ( filamentous ) , both of which are essential for such important cellular functions as the mobility and contraction of cells during cell division . </P>
