Computing on actin bundles network [PDF]
arXiv, 2019 Actin filaments are conductive to ionic currents, mechanical and voltage solitons. These travelling localisations can be utilised in making the actin network executing specific computing circuits. The propagation of localisations on a single actin filament is experimentally unfeasible, therefore we propose a `relaxed' version of the computing on actin ...

Twofold mechanosensitivity ensures actin cortex reinforcement upon peaks in mechanical tension [PDF]
arXiv, 2023 The actin cortex is an active biopolymer network underneath the plasma membrane at the periphery of mammalian cells. It is a major regulator of cell shape through the generation of active cortical tension. In addition, the cortex constitutes a mechanical shield that protects the cell during mechanical agitation. Cortical mechanics is tightly controlled

α-Smooth Muscle Actin and ACTA2 Gene Expressions in Vasculopathies
Brazilian Journal of Cardiovascular Surgery, 2015 α-smooth muscle actin, encoded by ACTA2 gene, is an isoform of the vascular smooth muscle actins, typically expressed in the vascular smooth muscle cells contributing to vascular motility and contraction. ACTA2 gene mutations cause a diversity of diffuse

Involvement of β- and γ-actin isoforms in actin cytoskeleton organization and migration abilities of bleb-forming human colon cancer cells. [PDF]
PLoS ONE, 2017 Amoeboid movement is characteristic for rounded cells, which do not form strong adhesion contacts with the ECM and use blebs as migratory protrusions. It is well known that actin is the main component of mature forms of these structures, but the exact ...

Septin filament organization in Saccharomyces cerevisiae. [PDF]
, 2012 Septins are a family of GTP-binding, membrane-interacting cytoskeletal proteins, highly conserved and essential in all eukaryotes (with the exception of plants). Septins play important roles in a number of cellular events that involve membrane remodeling

Actin cytoskeleton: Thinking globally, actin’ locally [PDF]
Current Biology, 2000 A class of proteins dubbed pipmodulins bind to and sequester the phospholipid PIP2 in the plasma membrane. Local release of PIP2 controls actin dynamics in specific subcellular regions and plays a critical role in regulating actin-based cell motility and morphogenesis.

Immunological detection of actin in the 14S ciliary dynein of Tetrahymena [PDF]
, 1994 The association of actin with Tetrahymena ciliary dyneins was examined using a polyclonal antibody against Tetrahymena actin. Western blotting shows that actin is present in the 14S dynein fraction, but not in the 22S dynein fraction, which comprises the

Dipotassium 4,4′-(hexane-3,4-diyl)bis(benzenesulfonate) dihydrate
Acta Crystallographica Section E, 2008 The anion of the title compound, also called sygethin dihydrate, 2K+·C18H20O6S22−·2H2O, has crystallographic inversion symmetry. The K+ cation is surrounded by eight O atoms in a distorted cubic coordination geometry, forming extended K ...
