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 this gene have been linked to cryptogenic cirrhosis. Two transcript variants encoding the same protein have been found for this gene. [provided by RefSeq, Jul 2008] Function: Involved in the uptake of thrombin-antithrombin complexes by hepatic cells (By similarity). When phosphorylated, plays a role in filament reorganization. Involved in the delivery of mutated CFTR to the plasma membrane. Together with KRT8, is involved in interleukin-6 (IL-6)-mediated barrier protection. Subunit: Heterotetramer of two type I and two type II keratins. KRT18 associates with KRT8. Interacts with PNN, HCV core protein and mutated CFTR. Interacts with YWHAE, YWHAH and YWHAZ only when phosphorylated. Interacts with the thrombin-antithrombin complex. Interacts with DNAJB6, TCHP and TRADD (By similarity). Subcellular Location: Cytoplasm, perinuclear region. Nucleus, nucleolus. Tissue Specificity: Expressed in endoderm, intestinal epithelial cells and in most extraembryonic tissues. Post-translational modifications: Phosphorylation at Ser-34 increases during mitosis. Hyperphosphorylated at Ser-53 in diseased cirrhosis liver. Phosphorylation increases by IL-6. Proteolytically cleaved by caspases during epithelial cell apoptosis. Cleavage occurs at Asp-238 by either caspase-3, caspase-6 or caspase-7. O-glycosylated at multiple sites; glycans consist of single N-acetylglucosamine residues. DISEASE: Defects in KRT18 are a cause of cirrhosis (CIRRH) [MIM:215600]. Similarity: Belongs to the intermediate filament family.
