  • 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.

  • Immunocytochemistry/Immunofluorescence analysis of human ovarian tumour tissue labelling Cytokeratin 18 with ab7549 conjugated to conjugated to QD655 at a molar ratio of 6:1 (Ab:QD). Tissue was incubated with primary antibody overnight at 4°C. Right image - tissue was incubated a further 2 hours at room temperature in order to remove background staining.
