Keratin 18 Keratin 18 Keratin 18 is a type I cytokeratin. It is, together with its filament partner keratin 8, perhaps the most commonly found products of the intermediate filament gene family. They are expressed in single layer epithelial tissues of the body. Mutations in this gene have been linked to cryptogenic cirrhosis. Two transcript variants encoding the same protein have been found for this gene. Keratin 18 is often used together with keratin 8 and keratin 19 to differentiate cells of epithelial origin from hematopoietic cells in tests that enumerate circulating tumor cells in blood. Keratin 18 has been shown to
Myosin light chain nodes to migrate into inflammatory sites in an S1PR1-dependent manner." The proposed mechanisms of action of CD69/Myl9/12 system are related to the regulation of airway inflammatory processes and thus can prove to be a novel therapeutic target for chronic inflammatory diseases, in general . Myosin light chain A myosin light chain is a light chain (small polypeptide subunit) of myosin. Myosin light chains were discovered by Chinese biochemist Cao Tianqin (Tien-chin Tsao) when he was a graduate student at the University of Cambridge in England. Structurally, myosin light chains belong to the EF-hand family, a large family of Ca- binding
