KRT18 encodes the type I intermediate filament chain keratin 18. Keratin 18, together with its filament partner keratin 8, are perhaps the most commonly found members of the intermediate filament gene family. They are expressed in single layer epithelial tissues of the body. Mutations in KRT18 have been linked to cryptogenic cirrhosis. Two transcript variants encoding the same protein have been found for KRT18.蛋白别名为:KRT18; CYK18; PIG46; Keratin, type I cytoskeletal 18; Cell proliferation-inducing gene 46 protein; Cytokeratin-18; CK-18; Keratin-18; K18;基因ID为:3875;蛋白质ID:P05783
