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
Tropomyosin is a long protein that associates with actin, a highly conserved thin filament protein found in organisms from yeast to humans.
