Tropomyosin Prevents Depolymerization of Actin Filaments from the Pointed End*

  • Pointed End
  • Published 2001


Regulation of the pointed, or slow-growing, end of actin filaments is essential to the regulation of filament length. The purpose of this study is to investigate the role of skeletal muscle tropomyosin (TM) in regulating pointed end assembly and disassembly in vitro. The effects of TM upon assembly and disassembly of actin monomers from the pointed filament… (More)
