Previous studies have reported that CAPZB is an essential element of the actin cytoskeleton whereby it binds to the barbed ends of actin filaments and regulates their polymerization [16].
In the present study, a very thin layer of actin filament along the bulge surface was detected.

It has been proposed that ABD2 can bind first to one F-actin filament, which in turn "activates"ABD1 and enables it to bind in a more ordered manner to another actin filament with a higher affinity [21].
(36) Furthermore, the myosin head could consistently interact with actin without moving away from the actin filament because it was firmly affixed to a large scanning probe thus preventing diffusion.
The basal ES present on both sides of the two adjacent Sertoli cell (SC) is typified by actin filament bundles existing between the endoplasmic reticulum (ER, see black asterisks) and TJ strand (see black arrowheads).
Organization of actin filaments in the axial rod of abalone sperm revealed by quick-freeze technique.
As Chara myosin has a long neck and the high duty ratio, it probably move processively with a long step size of about a half pitch of the actin filament along the actin cable.

For actin filament detection, cells were fixed with 4% paraformaldehyde, permeabilized with 0.5% Triton X-100 (Sigma-Aldrich), and stained with fluorescein-conjugated phalloidin (Sigma-Aldrich) at 37[degrees]C for 30 minutes.
(7) Therefore, the axial repeat of the troponin molecules (~38 nm, 5.5 nm x 7) along the actin filament does not coincide with the crossover repeat of the actin filament (~36 nm, 5.5 nm x 6.5).
Drubin, "Cofilin promotes rapid actin filament turnover in vivo," Nature, vol.
In the presence of [Ca.sup.2+], gelsolin severs and caps polymeric actin filaments (F-actin) (21): after binding of domain G1 and partly domain G2 to the actin filament (F-actin), gelsolin rapidly severs F-actin and then remains bound to the barbed end of one of the newly formed filaments, forming a stable cap, thus inhibiting addition of further monomers.
