Applications

Our Abpromise guarantee covers the use of ab212559 in the following tested applications.

The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.

Application Abreviews Notes
ICC/IF Use a concentration of 1 - 2 µg/ml.
Flow Cyt Use 0.5-1µg for 106 cells.

(in 0.1 ml).

IHC-P Use a concentration of 2 - 4 µg/ml. Perform heat mediated antigen retrieval with citrate buffer pH 6 before commencing with IHC staining protocol.

(Primary incubation for 30 min at RT).

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.
