  • 機能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.
  • 組織特異性Expressed in colon, placenta, liver and very weakly in exocervix. Increased expression observed in lymph nodes of breast carcinoma.
  • 関連疾患Defects in KRT18 are a cause of cirrhosis (CIRRH) [MIM:215600].
  • 配列類似性Belongs to the intermediate filament family.
  • 翻訳後修飾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.

  • Predicted band size : 47 kDa
    Western blotting analysis of cytokeratin 18 in HeLa cells with anti-cytokeratin 18 (C-04) biotin.
  • ab27553 at 1/100 staining mouse ES cell derived hepatocyte-like cells by ICC/IF. The cells were formaldehyde fixed and permeabilized with Triton X100 before being blocked with BSA and then incubated with the antibody for 18 hoursat 4°C.

  • ab27553 staining Cytokeratin 18 in Mouse mammary gland cells by Immunocytochemistry/ Immunofluorescence. Cells were fixed in 1:1 Acetone:Methanol and permeabilized with 0.025% Triton X-100 prior to blocking in 10% serum for 1 hour at 25°C. The primary antibody was applied at a concentration of 2 µg/mL and incubated with the sample for 15 hours at 4°C. The secondary antibody was Streptavidin-Cy3®-conjugated Mouse monoclonal, applied at a concentration of 1 µg/mL.
