• Background: Keratin-19 (KRT19) also known as keratin, type I cytoskeletal 19, cytokeratin-19 (CK-19), or CYFRA 21-1, is a 40 kDa protein that in humans is encoded by the KRT19 gene. Keratin 19 is a member of the keratin family. The keratins are intermediate filament proteins responsible for the structural integrity of epithelial cells and are subdivided into cytokeratins and hair keratins. Keratin 19 is a type I keratin. The type I cytokeratins consist of acidic proteins which are arranged in pairs of heterotypic keratin chains. KRT19 is the most used marker for the RT-PCR-mediated detection of tumor cells disseminated in lymph nodes, peripheral blood, and bone marrow of breast cancer patients. There is a positive correlation between higher expression of KRT19 in some kind of cancers and worse patient survival, where it serves as a diagnostic or prognostic biomarker.
