actin is a family of globular multi functional proteins that form microfilaments it is found in essentially all eukaryotic cells the only known exception being nematode sperm where it may be present at concentrations of over 100 Î¼m
Actin forms filaments ('F-actin' or microfilaments) that are essential elements of the eukaryotic cytoskeleton, able to undergo very fast polymerization and depolymerization dynamics. In most cells actin filaments form larger-scale networks which are essential for many key functions in cells:
