Gene Name keratin 19
Background Cytokeratin 19 (KRT19) is an intermediate filament (IF) protein that is part of the Keratin family of proteins. This protein is also known by the names of Keratin 19 or Keratin type I Cytoskeletal 19. The Keratin family consists of Keratin 1-20, which are divided into two subtypes: Type 1 contains the acidic Cytokeratin proteins consisting of Cytokeratins 9-20, including KRT19; Type 2 Keratins include the basic to neutral protein and contains Cytokeratin 1-8. Type 1 and Type 2 Keratins often form oligomers, interacting to create heterotypic chains. However, KRT19 is unique in that while being the smallest of the Type 1 Keratin proteins, it does not interact with any Type 2 Keratins. IF proteins such as KRT19 are integral for defining and maintaining cellular structure and morphology, and are important for cellular integrity by anchoring to membrane complexes via proteins such as Epiplakin, Trichoplein, Periplakin, Plakophilins, Plectin, BPAG1, Desmoplakin, and Envoplakin. KRT19 is also involved in the organization of the myofibers of striated muscle. KRT19 and other Cytokeratin proteins are mainly found in epithelial cells, with KRT19 being expressed exclusively in defined zones of basal keratinocytes. KRT19 is an important biomarker for breast cancer cells, tumor cells of the lymph nodes, peripheral blood, and bone marrow. Cytokeratin 19 can be expressed with KRT8 and KRT18 to differentiate cells of epithelial lines from hematopoietic tumor cells in the peripheral blood.
Synonyms CK19; K1CS; K19
Note This Cytokeratin 19 antibody is useful for Immunocytochemistry/Immunofluorescence, Western Blot where a band is seen ~44 kDa, and IHC-paraffin embedded sections. Prior to immunostaining paraffin tissues, antigen retrieval with sodium citrate buffer (pH 6.0) is recommended.
