The KRT80 gene encodes a type II keratin called KB20. Keratins are intermediate filament proteins responsible for the structural integrity of epithelial cells. They share a common structural organization consisting of an N-terminal head domain, a central α-helical rod domain and a C-terminal tail domain. The head domain is essential for intermediate filament assembly. Keratins are classified into type I (smaller, acidic) and type II (larger, neutral-to-basic) proteins. Type I keratin genes are located at two loci (17p11–12 and 17q11–22) on chromosome 17, whereas type II keratin genes are located to a single cluster (12q11–13) on chromosome 12. KB20 is expressed in murine lung tissue and oesophagus. A polymorphism in this gene associated with HbF response to hydroxyurea in patients with sickle cell disease, while the cellular mechanism involved is currently unknown.
