[[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: α (Aa) (or G-actin) found in muscle tissue, β (Ab) and γ (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]]). For more details see [[F-actin]]. | [[Actin]] is a protein found in all eukaryotic cells.
