Template:PBB Keratin, type II cytoskeletal 5 also known as KRT5 is a protein that in human is encoded by the KRT5 gene.
Function
The protein encoded by this gene is a member of the keratin gene family. The type II cytokeratins consist of basic or neutral proteins which are arranged in pairs of heterotypic (i.e., different types of) keratin chains coexpressed during differentiation of simple and stratified epithelial tissues. The type II cytokeratin genes are clustered in a region of chromosome 12q12-q13.
This type II cytokeratin is specifically expressed in the basal layer of the epidermis as a heterodimer with KRT14.
Clinical significance
Mutations in these genes have been associated with a complex of diseases termed epidermolysis bullosa simplex. In lung cancer affecting the proximal airways, stem cells that express keratin 5 are likely to be affected cell line.
Interactions
Keratin 5 has been shown to interact with ALOX12.
