Background

Function
Cytokeratin 4 (KRT4/CK4) is a type II keratin that pairs with KRT13 and is expressed in the spinous layer of non-keratinized stratified squamous epithelium. It assembles into an intermediate filament network to provide structural support and mechanical protection for the mucosal epithelium. Cytokeratin 4 mutation is a major cause of white cavernous nevus, characterized by white cavernous plaques on the oral mucosa. In addition, Cytokeratin 4 is downregulated in oral squamous cell carcinoma, esophageal squamous cell carcinoma and head and neck squamous cell carcinoma, and can serve as a tumor differentiation marker and a potential tumor suppressor[1].
-
Expression
Tissue specificity:
Detected in the suprabasal layer of the stratified epithelium of the esophagus, exocervix, vagina, mouth and lingual mucosa, and in cells and cell clusters in the mucosa and serous gland ducts of the esophageal submucosa (at protein level). Expressed widely in the exocervix and esophageal epithelium, with lowest levels detected in the basal cell layer. -
Isoforms & Post-Translational Modification
Cytokeratin 4: 520 amino acids, molecular weight 56,144 Da.
-
Subunit
Heterotetramer of two type I and two type II keratins. Keratin-4 is generally associated with keratin-13
