barbed ends

  • Electron micrographs have provided evidence of their fast-growing barbed-ends and their slow-growing pointed-end.
  • Subunits are added to barbed ends and lost from rear-facing pointed ends.
  • One end shows an indentation and is referred to as the barbed end while the other resembles an arrow head and is referred to as the pointed end.
  • The barbed end is the top, the feather the butt-end. Cited from The Morris Book, Pt. 1, by Cecil J. Sharp and Herbert C. Macilwaine
  • The javelin is grasped by the middle, the barbed end toward the back, and the plain rounded end is shot toward the hoop. Cited from Indian Games and Dances with Native Songs, by Alice C. Fletcher
  • The terms "pointed end" and "barbed end" refer to the " end" and "(+) end" respectively.
  • One formin of a dimer dissociates from the barbed end to take the next step while the second formin of the dimer remains bound.
  • Treadmilling results in elongation in the barbed end and shortening in the pointed-end, so that the filament in total moves.
  • ATP-bound actin then itself binds the barbed end, and the ATP is subsequently hydrolyzed.
  • As a result of ATP hydrolysis, filaments elongate approximately 10 times faster at their barbed ends than their pointed ends.
  • Additionally, the cell utilizes polyphosphoinositides to aid in the removal of all known "barbed end" capping proteins.
  • G-actin subunits preferentially add to the barbed end of the F-actin polymer and older units are removed from the pointed end.
  • One proposed model suggests the existence of actin filament barbed-end-tracking molecular motors termed "actoclampin".
  • At steady-state, the polymerization rate at the barbed end matches the depolymerization rate at the pointed end, and microfilaments are said to be treadmilling.
  • Myosin X walks towards the barbed ends of filaments.
  • In this process, G-actin subunits primarily add to the "barbed end" of the filamentous polymer.
  • Elongation is favored at the barbed end of the growing filament.
  • They are thus referred to as the plus end (with faster dynamics, also called barbed end) and the minus end (with slower dynamics, also called pointed end).
  • This gene encodes the alpha subunit of the barbed-end actin binding protein.
  • Thus, in environments with high concentrations of free actin subunits, filamentous growth at the "barbed end" remains greater than that of the "pointed end."
