Product Summary for Cytokeratin 17 Antibody (KRT17/778) [Alexa Fluor® 594]

Immunogen

Recombinant full-length human Cytokeratin 17 protein (Uniprot: Q04695)

Localization

Cytoplasmic

Specificity

Cytokeratin 17 (CK17) is normally expressed in the basal cells of complex epithelia but not in stratified or simple epithelia. Antibody to CK17 is an excellent tool to distinguish myoepithelial cells from luminal epithelium of various glands such as mammary, sweat and salivary. CK17 is expressed in epithelial cells of various origins, such as bronchial epithelial cells and skin appendages. It may be considered as epithelial stem cell marker because CK17 Ab marks basal cell differentiation. CK17 is expressed in SCLC much higher than in LADC. Eighty-five percent of the triple negative breast carcinomas immunoreact with basal cytokeratins including anti-CK17. Also important is that cases of triple negative breast carcinoma with expression of CK17 show an aggressive clinical course. Additionally, anti-CK17 and anti-MUC1 immunoreactivity represents pancreatobiliary subtype whereas anti-MUC2 and anti-CDX-2 positivity defines intestinal subtype.

Background: Cytokeratin 17

Among the members of the cytokeratin (CK) subfamily of intermediate filament (IF) proteins, CK 17 is normally expressed in the basal cells of complex epithelia but not in stratified or simple epithelia. It has an unusual expression pattern in normal and diseased states and has potential importance in tumor diagnosis. CK 17 synthesis seems to be a marker of basal cell differentiation in complex epithelia and therefore indicative of a certain type of epithelial "stem cells" (1). It has been shown that CK 17 regulates cell growth through binding to the adaptor protein 14-3-3sigma. These findings reveal a new and unexpected role for the intermediate filament cytoskeleton in influencing cell growth and size by regulating protein synthesis (2). CK 17 is expressed in the nail bed, hair follicle, sebaceous glands, and other epidermal appendages (3).
