The cytoskeleton consists of (a) microtubules, (b) microfilaments, and (c) intermediate filaments. [1]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]

Desmin IFs are structural components of the sarcomeres in muscle cells and connect different cell organelles like the desmosomes with the cytoskeleton. [22] Glial fibrillary acidic protein (GFAP) is found in astrocytes and other glia. Peripherin found in peripheral neurons.
In humans, the DMD gene is located on the short (p) arm of the X chromosome between positions 21.2 and 21.1. Dystrophin is a rod-shaped cytoplasmic protein, and a vital part of a protein complex that connects the cytoskeleton of a muscle fiber to the surrounding extracellular matrix through the cell membrane.
Merlin is a membrane-cytoskeleton scaffolding protein, i.e. linking actin filaments to cell membrane or membrane glycoproteins. [10] Human merlin is predominantly found in nervous tissue, but also in several other fetal tissues, and is mainly located in adherens junctions. [11]
The form discussed here is the one found in the 1950s to be linked to Rh blood group and more recently shown to be caused by a defect in protein 4.1. 'Rh-unlinked' forms of elliptocytosis are caused by mutation in the alpha- spectrin gene (MIM 182860), the beta- spectrin gene (MIM 182870), or the band 3 gene (MIM 109270) [supplied by OMIM].
In cell biology, the spindle apparatus is the cytoskeletal structure of eukaryotic cells that forms during cell division to separate sister chromatids between daughter cells. It is referred to as the mitotic spindle during mitosis , a process that produces genetically identical daughter cells, or the meiotic spindle during meiosis , a process ...
Specialized unique actin cytoskeletal structures are found adjacent to the plasma membrane. Four remarkable examples include red blood cells, human embryonic kidney cells, neurons, and sperm cells. In red blood cells, a spectrin-actin hexagonal lattice is formed by interconnected short actin filaments. [9]
