  • 功能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.
  • 组织特异性Expressed in colon, placenta, liver and very weakly in exocervix. Increased expression observed in lymph nodes of breast carcinoma.
  • 疾病相关Defects in KRT18 are a cause of cirrhosis (CIRRH) [MIM:215600].
  • 序列相似性Belongs to the intermediate filament family.
  • 翻译后修饰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.

Anti-Cytokeratin 18 antibody 图像

  • This image shows human breast carcinoma tissue stained with ab51148 at 1/50 dilution. The cells in the right hand image were treated with the immunogenic peptide, in the left hand image they were not.
  • All lanes : Anti-Cytokeratin 18 antibody (ab51148) at 1/500 dilution

    Lane 1 : HeLa cell extract treated with UV light for 5 minutes, with the immunising peptide
    Lane 2 : HeLa cell extract treated with UV light for 5 minutes, without the immunising peptide

    Predicted band size : 48 kDa
    Observed band size : 47 kDa (why is the actual band size different from the predicted?)
