Bundling of Actin Filaments by ct-Actinin Depends on Its Molecular Length

  title={Bundling of Actin Filaments by ct-Actinin Depends on Its Molecular Length},
  • Published 2002
Cross-linking of actin filaments (F-actin) into bundles and networks was investigated with three different isoforms of the dumbbell-shaped c~-actinin homodimer under identical reaction conditions. These were isolated from chicken gizzard smooth muscle, Acanthamoeba, and Dictyostelium, respectively. Examination in the electron microscope revealed that each isoform was able to cross-link F-actin into networks. In addition, F-actin bundles were obtained with chicken gizzard and Acanthamoeba a… CONTINUE READING
