WebIn general, intermediate filaments serve as structural elements, helping cells maintain their shape and integrity. For example, keratin filaments, the intermediate filaments of epithelial cells, which line surfaces of the body, give strength to the cell sheet that covers the surface. Mutations in keratin genes can result in blisters when the ... WebThe intermediate filaments of the M cell are arranged in meshworks of wavy bundles (B) as is characteristic for intermediate filaments in intestinal epithelium. The terminal web is characterised by a dense packing of mostly non-orientated filaments which are stained by immunogold (Bars = 0.5 μm).

Intermediate Filaments - Definition, Structure, Function

Cytokeratins are keratin proteins found in the intracytoplasmic cytoskeleton of epithelial tissue. They are an important component of intermediate filaments, which help cells resist mechanical stress. Expression of these cytokeratins within epithelial cells is largely specific to particular organs or tissues. … See more The term cytokeratin began to be used in the late 1970s, when the protein subunits of keratin intermediate filaments inside cells were first being identified and characterized. In 2006 a new systematic nomenclature for … See more The cytokeratins are encoded by a family encompassing 30 genes. Among them, 20 are epithelial genes and the remaining 10 are specific for trichocytes. All cytokeratin chains are composed of a central α-helix-rich domain (with a 50 to 90% sequence … See more • Cytokeratin at the U.S. National Library of Medicine Medical Subject Headings (MeSH) See more There are two categories of cytokeratins: the acidic type I cytokeratins and the basic or neutral type II cytokeratins. Within each category, cytokeratins are numbered in order of decreasing size, from high molecular weight (HMWCKs) to low molecular weight … See more In the cytoplasm, keratin filaments associate laterally with each other to create bundles of ~50 nm radius. The radius of these … See more WebNov 28, 2024 · Cytokeratins are a large group of intermediate filament proteins that form the cytoskeleton of epithelial cells and their appendages (hair, nails). Biochemically, cytokeratins are divided into two main types: acidic and basic. Each cytokeratin pair necessarily contains both acidic and basic cytokeratins in equimolar amounts.
