Unlike its related family members, this smallest known acidic cytokeratin is not paired with a basic cytokeratin in epithelial cells.
Cytokeratins are keratin proteins found in the intracytoplasmic cytoskeleton of epithelial tissue. They are an important component of intermediate filaments, which help cells resist mechanical stress. Expression of these cytokeratins within epithelial cells is largely specific to particular organs or tissues.
