- Activity summary
Cytokeratin 14 also known as CK14 keratin 14 or KRT14 is a type I keratin protein with a molecular mass of approximately 50 kDa. It forms intermediate filaments in epithelial cells primarily in the basal layer of stratified epithelium and is part of the cytoskeleton. Cytokeratin 14 expression appears in tissues such as the epidermis tongue and esophagus where it contributes to the structural integrity and mechanical stability of cells. Laboratories often utilize antibodies like anti-K14 and labels such as Alexa Fluor 555 or Alexa Fluor 647 to identify cytokeratin 14 in research settings.
- Biological function summary
This protein significantly contributes to the maintenance and regeneration of epithelial tissues by forming a network of filaments with keratin 5. KRT14 pairs with keratin 5 to create a keratin intermediate filament complex which plays a structural role in the resilience and elasticity of epithelial tissues. This partnership is essential for the assembly of the cytoskeleton and supports the protective barrier function of the skin and related tissues.
- Pathways
Cytokeratin 14 engages in pivotal cellular processes like keratinization and wound healing. The protein is actively involved in signal transduction pathways such as the epithelial cell differentiation pathway. Within these pathways KRT14 collaborates with KRT5 and other structural proteins to regulate cell proliferation and differentiation reflecting its importance in skin health and function.
- Associated diseases and disorders
Cytokeratin 14 associates with specific genetic conditions including epidermolysis bullosa simplex (EBS) and squamous cell carcinoma (SCC). In EBS mutations in the KRT14 gene lead to skin fragility. In SCC altered expression of KRT14 and related proteins such as keratin 5 can influence tumor progression and invasion. These associations highlight the critical role of KRT14 in both normal and pathological epithelial function.

Western blot - Anti-Cytokeratin 14 antibody [EPR17336] - BSA and Azide free (ab251249)
This data was developed using the same antibody clone in a different buffer formulation (Anti-Cytokeratin 14 antibody [EPR17336] ab197893).
Lanes 1 - 4: Merged signal (red and green). Green - Anti-Cytokeratin 14 antibody [EPR17336] ab197893 observed at 52 kDa. Red - loading control, Anti-GAPDH antibody [6C5] - Loading Control ab8245 (Mouse anti-GAPDH antibody [6C5]) observed at 37kDa.
Anti-Cytokeratin 14 antibody [EPR17336] ab197893 was shown to react with KRT14 in A431 wild-type cells in Western blot. Loss of signal was observed when KRT14 knockout sample was used. A431 wild-type and KRT14 knockout cell lysates were subjected to SDS-PAGE. Membranes were blocked in 3% Milk in TBS-T (0.1% Tween®) before incubation with Anti-Cytokeratin 14 antibody [EPR17336] ab197893 and Anti-GAPDH antibody [6C5] - Loading Control ab8245 (Mouse anti-GAPDH antibody [6C5]) overnight at 4°C at a 1 in 50000 dilution and a 1 in 20000 dilution respectively. Blots were developed with Goat anti-Rabbit IgG H&L (IRDye® 800CW) preabsorbed (Goat anti-Rabbit IgG H&L (IRDye® 800CW) preadsorbed ab216773) and Goat anti-Mouse IgG H&L (IRDye® 680RD) preabsorbed (Goat anti-Mouse IgG H&L (IRDye® 680RD) preadsorbed ab216776) secondary antibodies at 1 in 20000 dilution for 1 hour at room temperature before imaging.
