  • Contractile protein is the special proteins in muscles that contract and relax to cause movement.
  • The cytoplasm of cells is a colloidal network of contractile proteins.
  • Actin filaments are the major components of this network.
  • Other contractile proteins interact with this filament to create structural rigidity and movement.
