Actin isoforms and neoplastic transformation
Успехи молекулярной онкологии, 2017 The cytoplasmic actins (β and γ) play crucial roles during key cellular processes like adhesion, migration, polarization and cytokinesis. The understanding of their specific underlying mechanisms would be of major relevance not only for fundamental ...

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 ...

Fisheries and Aquatic Sciences, 2017 Background Teleosts represent unique features in the regulation of muscle development and growth, with a great deal of myogenic plasticity. Muscle actins are major components to compose muscle fibers, and they play essential roles in cellular mobility ...

Stability domains of actin genes and genomic evolution
, 2007 In eukaryotic genes the protein coding sequence is split into several fragments, the exons, separated by non-coding DNA stretches, the introns. Prokaryotes do not have introns in their genome.

Relative importance of βcyto- and γcyto-actin in primary mouse embryonic fibroblasts [PDF]
, 2017 The highly homologous β (βcyto) and γ (γcyto) cytoplasmic actins are hypothesized to carry out both redundant and unique essential functions, but studies using targeted gene knockout and siRNA-mediated transcript knockdown to examine βcyto- and γcyto ...

The Actin Cytoskeleton and Actin-Based Motility [PDF]
Cold Spring Harbor Perspectives in Biology, 2018 The actin cytoskeleton-a collection of actin filaments with their accessory and regulatory proteins-is the primary force-generating machinery in the cell. It can produce pushing (protrusive) forces through coordinated polymerization of multiple actin filaments or pulling (contractile) forces through sliding actin filaments along bipolar filaments of ...

F1000Research, 2016 Higher vertebrates (mammals and birds) express six different highly conserved actin isoforms that can be classified in three subgroups: 1) sarcomeric actins, α-skeletal (α-SKA) and α-cardiac (α-CAA), 2) smooth muscle actins (SMAs), α-SMA and γ-SMA, and 3)

, 2014 Collective dynamics and force generation by cytoskeletal filaments are crucial in many cellular processes. Investigating growth dynamics of a bundle of N independent cytoskeletal filaments pushing against a wall, we show that chemical switching (ATP/GTP ...

Rapid production of pure recombinant actin isoforms in Pichia pastoris [PDF]
, 2018 Actins are major eukaryotic cytoskeletal proteins, which perform many important cell functions, including cell division, cell polarity, wound healing, and muscle contraction.

Journal of Biological Chemistry, 2012 Background: Mutation of Asp-11 is dominant negative in yeast and human actins. Results: Mutant actins exchange bound nucleotides rapidly, cannot bind cofilin, and cofilin-induced depolymerization of mutant and wild type copolymers is slow.
