actin
A protein of 42 kD, very abundant in eukaryotic cells (8-14% total cell protein) and one of the major components of the actomyosin motor and the cortical microfilament meshwork. First isolated from striated muscle and often referred to as one of the muscle proteins. G-Actin is the globular monomeric form of actin, 6.7 x 4.0nm: it polymerizes to form filamentous F-actin.
