Evidence for biased bidirectional polymerization of actin filaments using heavy meromyosin prepared by an improved method.
Isolated actin filaments decorated with HMM can grow by addition of actin monomers to either end, although there is a bias toward addition at the end which is normally attached to the Z line in striated muscle.
