The Role of non-muscle actin paralogs in cell cycle progression and proliferation
European Journal of Cell Biology, 2023 Uncontrolled cell proliferation leads to several pathologies, including cancer. Thus, this process must be tightly regulated. The cell cycle accounts for cell proliferation, and its progression is coordinated with changes in cell shape, for which ...

The unusual dynamics of parasite actin result from isodesmic polymerization [PDF]
, 2013 Previous reports have indicated that parasite actins are short and inherently unstable, despite being required for motility. Here, we re-examine the polymerization properties of actin in Toxoplasma gondii (TgACTI), unexpectedly finding that it exhibits ...

Induction of Cytokinin-Independent Tobacco Tissues by Substituted Fluorenes [PDF]
, 1971 Two morphactins and three aminofluorenes initiated the formation of compact tissue nodules in hormone-dependent tobacco callus cultures. These nodules, upon subculture, behaved like partially transformed plant tumors.

Trends in Cell Biology, 1996 The most biologically significant property of actin is its ability to self-associate and form two-stranded polymeric microfilaments. In living cells, these micro filaments form the actin cytoskeleton, essential for maintenance of the shape, passive mechanical properties and active motility of eukaryotic cells. Recently discovered actin-related proteins

Effect of overexpression of β- and γ-actin isoforms on actin cytoskeleton organization and migration of human colon cancer cells [PDF]
, 2014 Actins are eukaryotic proteins, which are involved in diverse cellular functions including muscle contraction, cell motility, adhesion and maintenance of cell shape.

Actin and Actin-Binding Proteins [PDF]
Cold Spring Harbor Perspectives in Biology, 2016 Organisms from all domains of life depend on filaments of the protein actin to provide structure and to support internal movements. Many eukaryotic cells use forces produced by actin polymerization for their motility, and myosin motor proteins use ATP hydrolysis to produce force on actin filaments.

Differential Support of Aspergillus fumigatus Morphogenesis by Yeast and Human Actins. [PDF]
PLoS ONE, 2015 The actin cytoskeleton is highly conserved among eukaryotes and is essential for cellular processes regulating growth and differentiation. In fungi, filamentous actin (F-actin) orchestrates hyphal tip structure and extension via organization of exocytic ...

RNA interference in marine and freshwater sponges [PDF]
, 2011 Background: The marine sponge Tethya wilhelma and the freshwater sponge Ephydatia muelleri are emerging model organisms to study evolution, gene regulation, development, and physiology in non-bilaterian animal systems. Thus far, functional methods (i.e.,

Novel Actin Cytoskeleton. Actin Tubules.
Cell Structure and Function, 2000 In spores of Dictyostelium discoideum three actin filaments are bundled to form a novel tubular structure and the tubules are then organized into rods. These tubular structures we will term actin tubules. Actin tubules are reconstructed from the supernatant of spore homogenates, while the usual actin filaments were bundled after incubation of ...
