[[Actin]] is a protein found in all eukaryotic cells.<ref>PMID:11474115</ref> 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.

Actin participates in muscle contraction, cell motility, cell division and cytokinesis. Actin associated with myosin is responsible for most cell movements. | [[Actin]] is a protein found in all eukaryotic cells.<ref>PMID:11474115</ref> It is the monomer of two types of filaments: microfilaments which are part of the cytoskeleton and thin filaments which are part of muscles.
