Revision as of 12:38, 9 December 2010
Actin is a protein found in all eukaryotic cells. It is the monomer of two types of filaments: microfilaments which are part of the cytoskeleton and thin filaments which are part of muscles. Three isoforms of actin are identified: Alpha (Aa) (or G-actin) found in muscle tissue, beta (Ab) and gamma (Ag) actins are components of the cytoskeleton. F-actin is Aa bound to ATP. The images at the left and at the right correspond to one representative Actin, i.e. the crystal structure of rabbit Native G-actin (3hbt).
