ring formation in osteoclasts is essential for their bone resorbing function.
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.
Actin participates in many protein-protein interactions, including self-association of actin to form F-actin.
vc]) covalently binds to G-actin and F-actin
, and causes actin depolymerization, which leads to cell rounding (Kudryashov et al.
is required for spindle anchoring and rotation in Xenopus oocytes: a reexamination of the effects of cytochalasin B on oocyte maturation.
In cirrhotic cells the level of actin polymerization was significantly lower than that of normal platelets and reflected in the level of F-actin
, the polymerized form.
like IgA F-actin
, although currently underutilized.
Crystal violet staining and fluorescent staining for CD31, f-actin
and nuclei were performed according to protocols described previously (6).

He said that they have found that they had massive impairment of craniofacial skeletal development, however, this was fully restored when they added human PLS3 and the same thing happened when we added two other proteins, actinin 1 and actinin 4, F-actin
proteins2 which are involved in 'bundling' or building the 'scaffolding' for cells, and it seems that these proteins can compensate for the loss of PLS3.
