Cytokeratin 5 (CK5) is a member of the keratin family of intermediate filament proteins, which play critical roles in maintaining epithelial cell structure and integrity. Expressed predominantly in stratified and complex epithelia, CK5 is a type II keratin that pairs with type I keratins like CK14 to form a cytoskeletal network. It is primarily found in basal and myoepithelial cells of tissues such as the skin, breast, prostate, and respiratory tract, marking progenitor or stem cell populations involved in tissue regeneration and repair.
CK5 antibodies are widely used in research and diagnostics to identify cells of basal epithelial origin. In pathology, CK5 immunohistochemistry (IHC) helps distinguish epithelial tumor subtypes, such as basal-like breast cancers, squamous cell carcinomas, and certain lung cancers. It is particularly valuable in classifying triple-negative breast cancers (TNBCs) and differentiating them from luminal subtypes. Additionally, CK5 expression is linked to pathological conditions like psoriasis, epidermolysis bullosa simplex, and hyperproliferative skin disorders.
As a biomarker, CK5’s detection often complements other keratins (e.g., CK5/6 cocktails) to improve diagnostic accuracy. Its role in studying epithelial-mesenchymal transition (EMT) and cancer stem cells further underscores its research relevance. Overall, CK5 antibodies serve as essential tools for exploring epithelial biology, tumor heterogeneity, and disease mechanisms.
