Target Information
Cytokeratins (CK) are intermediate filaments found in epithelial cells, both keratinizing (e.g., skin) and non-keratinizing (e.g., mesothelial cells). At least 20 distinct CKs are known, categorized into type I (acidic polypeptides) and type II (basic polypeptides).
Keratin 14 belongs to the type I subfamily of low molecular weight keratins and pairs with keratin 5. It helps distinguish stratified epithelial cells from simple epithelial cells and serves as a useful marker for squamous cell carcinomas. Additionally, it is considered a prognostic marker in breast carcinoma.
