Catching a Walker in the Act—DNA Partitioning by ParA Family of Proteins

Frontiers in Microbiology, 2022
Partitioning the replicated genetic material is a crucial process in the cell cycle program of any life form. In bacteria, many plasmids utilize cytoskeletal proteins that include ParM and TubZ, the ancestors of the eukaryotic actin and tubulin ...

Nucleocytoplasmic Shuttling of Cytoskeletal Proteins: Molecular Mechanism and Biological Significance

International Journal of Cell Biology, 2012
Various nuclear functional complexes contain cytoskeletal proteins as regulatory subunits; for example, nuclear actin participates in transcriptional complexes, and actin-related proteins are integral to chromatin remodeling complexes.

Connecting two arrays: The emerging role of actin-microtubule cross-linking motor proteins

Frontiers in Plant Science, 2015
The cytoskeleton of plant cells, consisting of actin filaments (AFs) and microtubules (MTs), is a central structure for various intracellular processes, such as cell division, isotropic and polar growth, vesicle transport, cell shape and morphogenesis ...

Motor proteins traffic regulation by supply-demand balance of resources

, 2014
In cells and in vitro assays the number of motor proteins involved in biological transport processes is far from being unlimited. The cytoskeletal binding sites are in contact with the same finite reservoir of motors (either the cytosol or the flow ...

Modelling cytoskeletal traffic: an interplay between passive diffusion and active transport [PDF]

, 2012
We introduce the totally asymmetric exclusion process with Langmuir kinetics (TASEP-LK) on a network as a microscopic model for active motor protein transport on the cytoskeleton, immersed in the diffusive cytoplasm.

High-Frequency Irreversible Electroporation (H-FIRE) Induced Blood–Brain Barrier Disruption Is Mediated by Cytoskeletal Remodeling and Changes in Tight Junction Protein Regulation

Biomedicines, 2022
Glioblastoma is the deadliest malignant brain tumor. Its location behind the blood–brain barrier (BBB) presents a therapeutic challenge by preventing effective delivery of most chemotherapeutics.

SILAC-based proteomic quantification of chemoattractant-induced cytoskeleton dynamics on a second to minute timescale [PDF]

, 2014
Cytoskeletal dynamics during cell behaviours ranging from endocytosis and exocytosis to cell division and movement is controlled by a complex network of signalling pathways, the full details of which are as yet unresolved.

Regulation of store-operated Ca2+ entry by Septins

Frontiers in Cell and Developmental Biology, 2016
The mechanism of store-operated Ca2+entry (SOCE) brings extracellular Ca2+ into cells after depletion of intracellular Ca2+ stores. Regulation of Ca2+ homeostasis by SOCE helps control various intracellular signaling functions in both non-excitable and ...

Deformation of crosslinked semiflexible polymer networks

, 2003
Networks of filamentous proteins play a crucial role in cell mechanics. These cytoskeletal networks, together with various crosslinking and other associated proteins largely determine the (visco)elastic response of cells.

The mechano-chemistry of cytoskeletal force generation [PDF]

, 2014
In this communication, we propose a model to study the non-equilibrium process by which actin stress fibers develop force in contractile cells. The emphasis here is on the non-equilibrium thermodynamics, which is necessary to address the mechanics as ...
