High molecular weight cytokeratins
WebHigh molecular weight cytokeratins are expressed in a variety of normal and neoplastic epithelial tissues (1). 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 (LMWCKs). Cytokeratins are usually found in … See more 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 … 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 … See more In the cytoplasm, keratin filaments associate laterally with each other to create bundles of ~50 nm radius. The radius of these bundles is set by the interplay between long range electrostatic repulsion and short range hydrophobic attraction. These … 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 … See more • Cytokeratin at the U.S. National Library of Medicine Medical Subject Headings (MeSH) See more
