  • Title: Muscle beta-actinin inhibits elongation of the pointed end of the actin filaments of brush border microvilli.
    Author: Yokota E, Maruyama K.
    Journal: J Biochem; 1983 Dec; 94(6):1897-900. PubMed ID: 6671972.
    Abstract:
    By using isolated actin bundles of brush border microvilli of chicken intestinal epithelial cells, it was clearly visualized that muscle beta-actinin caps the pointed end of an actin filament, whereas cytochalasin D masks the barbed end. The growth rate at the barbed end in the presence of beta-actinin was markedly slower than in its absence.
