    Glossary Keratin 19

    protein in epithelial cells used as a cancer biomarker

    Keratin 19 (KRT19 or CK19) is a type of protein found in the epithelial cells that line the surfaces and cavities of organs. It plays a crucial role in maintaining the structural integrity of these cells. In medical diagnostics, KRT19 is often used as a biomarker to detect certain types of cancers, as its expression levels can be indicative of tumor presence and progression.
