The KRT16 protein is a member of the keratin (type I) family. The keratins are intermediate filament proteins responsible for the structural integrity of epithelial cells and are subdivided into cytokeratins and hairkeratins. Epidermis-specific type I keratin that plays a key role in skin, acts as a regulator of innate immunity in response to skin barrier breach, required for some inflammatory checkpoint for the skin barrier maintenance. This keratin has been coexpressed with keratin 14 in a number of epithelial tissues, including esophagus, tongue, and hair follicles. Cytokeratin 16 is expressed in benign stratified squamous epithelium and squamous cell carcinoma of the head and neck, as well as luminal cells of mammary gland and sweat ducts. It is absent in non-invasive breast carcinomas and normal breast tissue.
