Alternative Name Cytokeratin 19
Background Cytokeratin 19 is a member of the keratin family. The keratins are intermediate filamentproteins responsible for the structural integrity of epithelial cells and are subdivided intocytokeratins and hair keratins. The type I cytokeratins consist of acidic proteins which arearranged in pairs of heterotypic keratin chains. Unlike its related family members, thissmallest known acidic cytokeratin is not paired with a basic cytokeratin in epithelial cells. It is specifically expressed in the periderm, the transiently superficial layer that envelopesthe developing epidermis. Keratin 19 is not expressed in hepatocytes, therefore, antibodyto keratin 19 is useful in the identification of liver metastasis. The degree of keratin 19positivity in breast cancer distinguishes malignant from benign tumours. Keratin 19 is oftenco-expressed with keratin 7.
