actins

Filamentary contractile proteins forming the cytoskeleton of cells. Actins contribute to cell shape, cell motility and to some internal cell functions.

So even if eukaryotic actin cytoskeleton was able to generate a force on the membrane, it seems other two mechanisms were necessary, first a projection force produced by polymerization and second, a motor molecule to move the actin filaments and put them near each other or to a membrane (Cox, Foster, Hirt, Harris, and Embley, 2008).
Under this idea, if all this was possible, then the polymerization-based membrane protrusion process would be able to develop almost naturally as a result of actin assembly, while the add-on of contractile machineries involving other steps to evolve the set of motor molecules and actin-binding proteins (Wickstead and Gull, 2011).
Furthermore, confocal microscopy findings confirmed that PEG contributes to the regulation of endothelial cell barrier by rearranging the actin cytoskeleton.

He said that they have discovered that Plasmodium actin filaments are very different from other actin filaments and now that they know the structural basis for this, we can look for ways to specifically interfere with the parasite cytoskeleton to the of this protein in the parasite in high detail.
Actin is the major cytoskeletal protein and involved in a variety of processes including cellular motility, intracellular transport, cytoskeletal structure, cell-surface mobility, cytokinesis, cytoplasmic streaming, clot retardation, microvillar movement, exocytosis and endocytosis, and probably chromosomal condensation and mitosis (Sheterline et al., 1996).
Higher eukaryotic organisms express several actin genes however their primary structure is similar.
Actin participates in many protein-protein interactions, including self-association of actin to form F-actin.
Titin is considered a giant muscular protein and is the third most abundant protein in skeletal muscle (after actin and myosin).
To better understand the process of the simultaneous formation of the first two polar bodies in an androgenetic clam, the meiotic process was observed by visualizing cytoskeletal elements, such as microtubules and centrosomes, and distribution of actin. In the present study, the detailed process of cytokinesis during the formation of the first two polar bodies in Corbicula fluminea was demonstrated by confocal microscopy.
Thirty-five adult male Wistar rats (Charles River Laboratories, Spain), with body weight 200-220 g at the beginning of the experiments, were used for the behavioral and nestin/ actin Western blot experiments.
Leiomyosarcoma cells are frequently positive for vimentin, smooth muscle actin, and muscle-specific or pan-muscle actin.
