A functional link between the actin cytoskeleton and lipid rafts during budding of filamentous influenza virions [PDF]

open access: yes, 2002
Morphogenesis of influenza virus is a poorly understood process that produces two types of enveloped virion: approximately 100-nm spheres and similar diameter filaments that reach 20 microm in length. Spherical particles assemble at plasma membrane lipid

The Actin/Spectrin Membrane-Associated Periodic Skeleton in Neurons

open access: yesFrontiers in Synaptic Neuroscience, 2018
Neurons are the most asymmetric cell types, with their axons commonly extending over lengths that are thousand times longer than the diameter of the cell soma.

Actin' like actin?

open access: yesTrends 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

Nucleotide-dependent activities of FtsA regulate the early establishment of a functional divisome during the Escherichia coli cell cycle

open access: yesFrontiers in Microbiology, 2023
During cell division in Escherichia coli, the highly conserved tubulin homolog FtsZ polymerizes and assembles into a ring-like structure, called the Z-ring, at the site of septation.

Altering the stability of the Cdc8 overlap region modulates the ability of this tropomyosin to bind cooperatively to actin and regulate myosin. [PDF]

open access: yes, 2011
Tropomyosin (Tm) is an evolutionarily conserved ?-helical coiled-coil protein, dimers of which form end-to-end polymers capable of associating with and stabilising actin-filaments and regulate myosin function. The fission yeast, Schizosaccharomyces pombe,

PIN2 Polarity Establishment in Arabidopsis in the Absence of an Intact Cytoskeleton

open access: yesBiomolecules, 2019
Cell polarity is crucial for the coordinated development of all multicellular organisms. In plants, this is exemplified by the PIN-FORMED (PIN) efflux carriers of the phytohormone auxin: The polar subcellular localization of the PINs is instructive to ...

Siglec-8 Signals Through a Non-Canonical Pathway to Cause Human Eosinophil Death In Vitro

open access: yesFrontiers in Immunology, 2021
Sialic acid-binding immunoglobulin-like lectin (Siglec)-8 is a glycan-binding receptor bearing immunoreceptor tyrosine-based inhibitory and switch motifs (ITIM and ITSM, respectively) that is selectively expressed on eosinophils, mast cells, and, to a ...

High Temporal Resolution 3D Live-Cell Imaging of Budding Yeast Meiosis Defines Discontinuous Actin/Telomere-Mediated Chromosome Motion, Correlated Nuclear Envelope Deformation and Actin Filament Dynamics

open access: yesFrontiers in Cell and Developmental Biology, 2021
Chromosome movement is prominent at mid-meiotic prophase and is proposed to enhance the efficiency and/or stringency of homolog pairing and/or to help prevent or resolve topological entanglements.

Novel Actin Cytoskeleton. Actin Tubules.

open access: yesCell 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 ...

Viscoelastic response of cells and the role of actin cytoskeletal remodelling. [PDF]

open access: yes, 2012
PhDThe mechanical properties of living cells provide useful information on cellular structure and function. In the present study a micropipette aspiration technique was developed to investigate the viscoelastic parameters of isolated articular ...
