The cytoskeleton is a complex, dynamic network of interlinking protein filaments present in the cytoplasm of all cells, including those of bacteria and archaea. [2] In eukaryotes , it extends from the cell nucleus to the cell membrane and is composed of similar proteins in the various organisms.
Cytoskeleton is a peer-reviewed scientific journal covering cytoskeletal research. The journal publishes original research pertaining to cell motility and cytoskeletons, spanning genetic and cell biological observations, biochemical, biophysical and structural studies, mathematical modeling, and theory.
Website Official profile Alexander D. Bershadsky is a cell biologist and mechanobiologist working on the self-organization of the actin cytoskeleton , the regulation of cell motility , and the mechanosensory functions of cell adhesion complexes.

The prokaryotic cytoskeleton is the collective name for all structural filaments in prokaryotes. [2] Some of these proteins are analogues of those in eukaryotes , while others are unique to prokaryotes.
While cellular processes can be supported by any of the three major components of the cytoskeleton—microfilaments (actin filaments), intermediate filaments (IFs), or microtubules—, lamellipodia are primarily driven by the polymerization of actin microfilaments, not microtubules. [3] [20]
Microtubule and tubulin metrics [1]. Microtubules are polymers of tubulin that form part of the cytoskeleton and provide structure and shape to eukaryotic cells. Microtubules can be as long as 50 micrometres, as wide as 23 to 27 nm [2] and have an inner diameter between 11 and 15 nm. [3]
In neuronal axons, the actin or spectric cytoskeleton forms an array of periodic rings [10] and in the sperm flagellum it forms a helical structure. [11] In plant cells, the cell cortex is reinforced by cortical microtubules underlying the plasma membrane. The direction of these cortical microtubules determines which way the cell elongates when ...
