Activity summary

Cytokeratin 13 also known as KRT13 or CK13 is a type I intermediate filament protein weighing approximately 44 kDa. It is one of the cytokeratin types that plays a critical role in the mechanical stability and integrity of epithelial cells. Cytokeratin 13 is expressed in the stratified squamous epithelium particularly in the upper layers of non-cornified epithelia which include the esophagus tongue and cervix. This protein forms heteropolymers with type II keratins contributing to the cytoskeletal filament network within epithelial cells.

Biological function summary

This protein participates in maintaining the structural framework and dynamics within epithelial tissues. As part of the cytoskeletal complex cytokeratin 13 supports cellular resilience against mechanical stress. It interacts with other cytokeratins contributing to the formation of a robust keratin filament network essential for epithelial cell function and differentiation. Its expression and regulation are key to the homeostasis of the tissues where it is found ensuring proper cell division and tissue integrity.

Pathways

Cytokeratin 13 integrates into epithelial cell differentiation and repair processes. It is involved in the epithelial-mesenchymal transition (EMT) pathway important for tissue development wound healing and cancer metastasis. During the EMT process cytokeratin 13 often works alongside proteins like E-cadherin and Vimentin mediating changes in epithelial cell architecture and polarity. This modulation is essential for cellular plasticity and response to environmental cues.

Associated diseases and disorders

Cytokeratin 13 has associations with certain epithelial tissue abnormalities such as oral squamous cell carcinoma and a subgroup of inherited blistering diseases like epidermolysis bullosa. In oral squamous cell carcinoma dysregulation of cytokeratin 13 expression may indicate tumor progression and metastasis. In epidermolysis bullosa mutations affecting keratin interactions including those with other keratins like cytokeratin 14 can lead to fragile skin and mucosal surfaces resulting in increased susceptibility to physical damage and impaired healing.

    ab198584 staining Cytokeratin 13 in A431 cells. The cells were fixed with 100% methanol (5 min), permeabilized with 0.1% Triton X-100 for 5 minutes and then blocked with 1% BSA/10% normal goat serum/0.3M glycine in 0.1% PBS-Tween for 1h. The cells were then incubated overnight at +4°C with ab198584 at a 1/100 dilution (shown in green) and Alexa Fluor® 594 Anti-alpha Tubulin antibody [DM1A] - Microtubule Marker ab195889, Mouse monoclonal to alpha Tubulin (Alexa Fluor® 594), at a 1/250 dilution (shown in red). Nuclear DNA was labelled with DAPI (shown in blue).

    Image was taken with a confocal microscope (Leica-Microsystems, TCS SP8).

    This product also gave a positive signal under the same testing conditions in A431 cells fixed with 4% formaldehyde (10 min).

    Overlay histogram showing A431 cells stained with ab198584 (red line). The cells were fixed with 4% formaldehyde (10 min) and then permeabilized with 0.1% PBS-Triton X-100 for 20 min. The cells were then incubated in 1x PBS / 10% normal goat serum / 0.3M glycine to block non-specific protein-protein interactions followed by the antibody (ab198584, 1/500 dilution) for 30 min at 22°C. Isotype control antibody (black line) was rabbit IgG (monoclonal) Alexa Fluor® 488 used at the same concentration and conditions as the primary antibody. Unlabelled sample (blue line) was also used as a control.

    Acquisition of >5,000 events were collected using a 20mW Argon ion laser (488nm) and 525/30 bandpass filter.

    This antibody gave a positive signal in A431 fixed with 80% methanol (5 min)/permeabilized with 0.1% PBS-Triton X-100 for 20 min used under the same conditions.
