Western blot - Anti-Cytokeratin 13 antibody [EPR3672] (AB133340)

False colour image of Western blot : Anti-Cytokeratin 13 antibody [EPR3672] staining at 1/2000 dilution, shown in green; Mouse anti-GAPDH antibody [6C5] (ab8245) loading control staining at 1/20000 dilution, shown in red. In Western blot, ab133340 was shown to bind specifically to Cytokeratin 13. A band was observed at 51 kDa in wild-type A431 cell lysates with no signal observed at this size in Krt13 knockout cell line ab269483 (knockout cell lysate ab269647). To generate this image, wild-type and Krt13 knockout A431 cell lysates were analysed. First, samples were run on an SDS-PAGE gel then transferred onto a nitrocellulose membrane. Membranes were blocked in 3 % milk in TBS-0.1 % Tween^® 20 (TBS-T) before incubation with primary antibodies overnight at 4 °C. Blots were washed four times in TBS-T, incubated with secondary antibodies for 1 h at room temperature, washed again four times then imaged. Secondary antibodies used were Goat anti-Rabbit IgG H&L (IRDye^® 800CW) preabsorbed (ab216773) and Goat anti-Mouse IgG H&L (IRDye^® 680RD) preabsorbed (ab216776) at 1/20000 dilution.

Supplementary information

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.

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.
