Actin Products

Actin is a 43 kDa protein that is very highly conserved between species. Actin has three main isotypes (α-actin, β-actin and γ-actin), which show > 90% amino-acid (aa) homology between isotypes and > 98% homology within members of a particular isotypic group. The majority of the isotype heterogeneity is located in the amino-terminal 30 residues. The amino-terminus of actin is located on the periphery of the double-helix in F-actin (4) and this site is also thought to interact with myosin (5).
