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
The smooth muscle cell contains less protein than a typical striated muscle cell and much less myosin. The actin content is similar, so the ratio of actin to myosin is ~6:1 in striated muscle and ~15:1 in smooth muscle.
