F-ac·tin

(ak'tin),
the association of G-actin subunits into a fibrous (F) protein caused by an increase in salt concentration; the conversion of G-actin to F-actin is catalyzed by small concentrations of magnesium ion, is reversible, and is accompanied by the conversion of the bound ATP molecule to ADP and phosphate and the conversion of one reactive -thiol group to an unreactive form.

To better understand the molecular mechanisms underlying the deleterious effects of COQ6, Western blot analysis of nephrin and F-actin was conducted, and the expression levels of both proteins were significantly lower in the si-RNA-COQ6 group than in the control group [Figure 2]b and [Figure 2]c.
Further experimental studies are required to explore the function of LOOP-1 in the binding of plastin-3 to F-actin.

Alexa Fluor[R] 555 phalloidin was used to stain F-actin. Fluorescent images were examined using a Leica TCS SP5 confocal microscope.

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.
When viewed at the apical surface, F-actin labeled (rhodamine phalloidin) epithelial cells of non-morphogenic appendages were shaped like flat tiles; the epithelium was uniform in appearance, and each cell contained a distinctive peripheral band of actin adjacent to the apical cell border (Fig.
The actin microfilaments distribution was examined using phalloidin, which specifically binds to polymerized actin or F-actin. Control cells (Figure 6(a)) show typical microfilament bundles in the cytoplasm towards the plasma membrane.
The C-terminal domain can mediate the link between the actin cytoskeleton and the plasma membrane through F-actin binding site [5].
