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 endocrine, exocrine, and mesothelial cells.
Cytokeratin 18 is found primarily 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 found for the cytokeratin 18 gene.
Cytokeratin subtype expression patterns are used increasingly for distinguishing epithelial malignancies.
Cytokeratin antibodies assist in tumor differential diagnosis using immunohistochemistry and are useful in cytopathology and flow cytometric assays.
