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 tract, respiratory tract, urogenital tract, endocrine and exocrine tissues, and mesothelial cells.
Found primarily in non-squamous epithelia, Cytokeratin 18 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 aid in distinguishing epithelial malignancies and are useful in tumor differential diagnosis, cytopathology, and flow cytometric assays.
