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 is associated with tropomyosin and the troponin complex in muscle. Actin also contains a myosin binding site, where it forms temporary complexes with myosin during muscle contraction, and permanently during rigor mortis (Pollard 1990). Molecular Characteristics: Actin consists of 376 amino acids.
