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.

Confocal image showing cytoplasm staining on PC-12 cell line. The nuclear counter stain is DAPI (blue). Tubulin is detected with ab7291 (anti-Tubulin mouse mAb) at 1/1000 dilution and ab150120 (AlexaFluor®594 Goat anti-Mouse secondary) at 1/500 dilution (red).
    The negative controls are as follows:
