Target Information
Cytokeratin 18 (Keratin 18, KRT18, type I cytoskeletal 18) belongs to the type A (acidic) subfamily of low molecular weight keratins and exists in combination with cytokeratin 8. It is expressed in tissues from the gastrointestinal, respiratory, and urogenital tracts, as well as in endocrine, exocrine, and mesothelial cells. Cytokeratin 18 is found mainly in non-squamous epithelia and is present in most adenocarcinomas and ductal carcinomas, but not in squamous cell carcinomas. Hepatocellular carcinomas express only cytokeratins 8 and 18. Mutations in the cytokeratin 18 gene have been linked to cryptogenic cirrhosis. Two transcript variants encoding the same protein have been identified. Cytokeratin subtype expression patterns are useful for distinguishing different epithelial malignancies. Cytokeratin antibodies assist in tumor differential diagnosis via immunohistochemistry and are valuable tools in cytopathology and flow cytometric assays.
