F-actin in conifer roots [PDF]

Proceedings of the National Academy of Sciences, 1982
The distribution of F-actin in the complex tissues of a higher plant organ has been visualized by fluorescence labeling the roots of the conifers Chamaecyparis obtusa and Pseudotsuga menziesii with F-actin-specific fluorescent dye-conjugated phallicidin.

Nuclear Actin Polymerization Regulates Cell Epithelial‐Mesenchymal Transition

Advanced Science, 2023
Current studies on actin function primarily rely on cytoplasmic actin due to the absence of cellular models specifically expressing nuclear actin. Here, cell models capable of expressing varying levels of nuclear F/G‐actin are generated and a significant

Mechanics of the F-actin cytoskeleton [PDF]

Journal of Biomechanics, 2010
Dynamic regulation of the filamentous actin (F-actin) cytoskeleton is critical to numerous physical cellular processes, including cell adhesion, migration and division. Each of these processes require precise regulation of cell shape and mechanical force generation which, to a large degree, is regulated by the dynamic mechanical behaviors of a diverse ...

Affimer proteins for F-actin: novel affinity reagents that label F-actin in live and fixed cells [PDF]

, 2018
Imaging the actin cytoskeleton in cells uses a wide range of approaches. Typically, a fluorescent derivative of the small cyclic peptide phalloidin is used to image F-actin in fixed cells. Lifeact and F-tractin are popular for imaging the cytoskeleton in

Hsp27-Actin Interaction

Biochemistry Research International, 2011
Hsp27 oligomer is reported to interact with F-actin as a barbed-end-capping protein. The present study determined the binding strength and stoichiometry of the interaction using fluorescence of probes attached to Hsp27 cysteine-137.

Catastrophic disassembly of actin filaments via Mical-mediated oxidation. [PDF]

, 2017
Actin filament assembly and disassembly are vital for cell functions. MICAL Redox enzymes are important post-translational effectors of actin that stereo-specifically oxidize actin's M44 and M47 residues to induce cellular F-actin disassembly.

Adhesive F-actin waves: a novel integrin-mediated adhesion complex coupled to ventral actin polymerization. [PDF]

PLoS ONE, 2011
At the leading lamellipodium of migrating cells, protrusion of an Arp2/3-nucleated actin network is coupled to formation of integrin-based adhesions, suggesting that Arp2/3-mediated actin polymerization and integrin-dependent adhesion may be ...

Actin polymerization and depolymerization in developing vertebrates

Frontiers in Physiology, 2023
Development is a complex process that occurs throughout the life cycle. F-actin, a major component of the cytoskeleton, is essential for the morphogenesis of tissues and organs during development.

A continuous isotropic-nematic liquid crystalline transition of F-actin solutions

, 2002
The phase transition from the isotropic (I) to nematic (N) liquid crystalline suspension of F-actin of average length $3~\mu$m or above was studied by local measurements of optical birefringence and protein concentration. Both parameters were detected to

Migration and homeostasis of naive T cells depends on coronin 1-mediated prosurvival signals and not on coronin 1-dependent filamentous actin modulation [PDF]

, 2011
Coronins are WD repeat-containing proteins highly conserved in the eukaryotic kingdom implicated in the regulation of F-actin. Mammalian coronin 1, one of the most conserved isoforms expressed in leukocytes, regulates survival of T cells, which has been ...
