While expressed in many tissues of the body, dystrophin has the critical role of stabilizing the muscle membrane (sarcolemma) during muscle contraction and its absence results in Duchenne muscular dystrophy (DMD).

Keratin is present in general in epithelial cells. neurofilaments of neural cells. made of lamin, giving structural support to the nuclear envelope. ... See more The cytoskeleton is a complex, dynamic network of interlinking protein filaments present in the cytoplasm of all cells, including those of bacteria and archaea. In eukaryotes, it extends from the cell nucleus to the See more Eukaryotic cells contain three main kinds of cytoskeletal filaments: microfilaments, microtubules, and intermediate filaments. In See more The cytoskeleton is a highly anisotropic and dynamic network, constantly remodeling itself in response to the changing cellular microenvironment. The network influences cell mechanics and dynamics by differentially polymerizing and depolymerizing … See more By definition, the cytoskeleton is composed of proteins that can form longitudinal arrays (fibres) in all organisms. These … See more In 1903, Nikolai K. Koltsov proposed that the shape of cells was determined by a network of tubules that he termed the cytoskeleton. The … See more Prior to the work of Jones et al., 2001, the cell wall was believed to be the deciding factor for many bacterial cell shapes, including rods and spirals.
