Target

  • Function

    Together with KRT19, helps to link the contractile apparatus to dystrophin at the costameres of striated muscle.
  • Tissue specificity

    Observed in muscle fibers accumulating in the costameres of myoplasm at the sarcolemma membrane in structures that contain dystrophin and spectrin. Expressed in gingival mucosa and hard palate of the oral cavity.
  • Involvement in disease

    Cirrhosis
  • Sequence similarities

    Belongs to the intermediate filament family.
  • Post-translational
    modifications

    Phosphorylation on serine residues is enhanced during EGF stimulation and mitosis. Ser-74 phosphorylation plays an important role in keratin filament reorganization.
    O-glycosylated. O-GlcNAcylation at multiple sites increases solubility, and decreases stability by inducing proteasomal degradation.
    O-glycosylated (O-GlcNAcylated), in a cell cycle-dependent manner.
  • Cellular localization

    Cytoplasm. Nucleus, nucleoplasm. Nucleus matrix.

  • H89 blocks the 8-Br-cAMP-induced differentiation of WJ-MSCs into ESC-like cells.

    (Panel A) Flow cytometric analysis of cells in the five groups using antibodies against vimentin and CD13.

    (a) no inhibition group; (b) p38 MAPK-block group; (c) ERK1/2-block group; (d) PKA-block group; (e) no differentiation group. Cells in Groups a–d treated with 8-Br-cAMP for 21 days.

  • ab192468 staining Cytokeratin 8 in HeLa cells. The cells were fixed with 4% formaldehyde (10 min) and then blocked in 1% BSA/10% normal goat serum/0.3M glycine in 0.1% PBS-Triton X-100 for 1hr. The cells were then incubated with ab192468 at a working dilution of 1 in 50 (shown in red) and ab7291 (Mouse monoclonal [DM1A] to alpha Tubulin) at 1µg/ml overnight at +4°C, followed by a further incubation at room temperature for 1hr with AlexaFluor® 488 Goat anti-mouse IgG (H&L - preadsorbed) (ab150117) at 2 μg/ml (shown in green). Nuclear DNA was labelled in blue with DAPI.

    This product gave a positive signal in 100% methanol (5 min) fixed HeLa cells tested under the same conditions.

    Image was taken with a Confocal microscope (Leica-microsystems, TCS SP8).

  • Overlay histogram showing HeLa cells stained with ab192468 (red line). The cells were fixed with 4% formaldehyde (10 min) and then permeabilized with 0.1% PBS-Triton X-100 for 20 min. The cells were then incubated in 1x PBS / 10% normal goat serum / 0.3M glycine to block non-specific protein-protein interactions followed by the antibody (ab192468, 2μl/1x106) for 30 min at 22ºC. Isotype control antibody (black line) was rabbit IgG (monoclonal) (Alexa Fluor® 647) (2μl/1x106) for 30 min at 22°C. Unlabelled sample (blue line) was also used as a control.

    Acquisition of >5,000 events were collected using a 25mW red solid state diode laser (635nm) and 675/30 bandpass filter.

    This antibody gave a positive signal in HeLa fixed with 80% methanol (5 min)/permeabilized with 0.1% PBS-Triton X-100 for 20 min used under the same conditions.
