Target

  • 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.
  • Tissue specificity
    Expressed in colon, placenta, liver and very weakly in exocervix. Increased expression observed in lymph nodes of breast carcinoma.
  • Involvement in disease
    Defects in KRT18 are a cause of cirrhosis (CIRRH) [MIM:215600].
  • Sequence similarities
    Belongs to the intermediate filament family.
  • 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.
  • Cellular localization
    Cytoplasm > perinuclear region.
