- Tropomyosin (Tm) is a binding protein of actin in fine muscle filaments, with a molecular weight of 2 × 35kDa and a length of 41nm. It consists of two parallel polypeptide chains in an alpha helix configuration. Each tropomyosin The end-to-end protein forms a continuous chain that binds to the actin filaments, and is located in the grooves of the double helix. Each tropomyosin has seven actin binding sites, so Tm binds to seven actin subunits in actin filaments.
