Target

  • FunctionTogether with KRT19, helps to link the contractile apparatus to dystrophin at the costameres of striated muscle.
  • Tissue specificityObserved 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 diseaseCirrhosis
  • Sequence similaritiesBelongs 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 localizationCytoplasm. Nucleus, nucleoplasm. Nucleus matrix.

  • ICC/IF image of ab87883 stained HeLa cells. The cells were 4% PFA fixed (10 min) and then incubated in 1%BSA / 10% normal goat serum / 0.3M glycine in 0.1% PBS-Tween for 1h to permeabilise the cells and block non-specific protein-protein interactions. The cells were then incubated with the antibody (ab87883, 1µg/ml) overnight at +4°C. The secondary antibody (green) was Alexa Fluor® 488 goat anti-rabbit IgG (H+L) used at a 1/1000 dilution for 1h. Alexa Fluor® 594 WGA was used to label plasma membranes (red) at a 1/200 dilution for 1h. DAPI was used to stain the cell nuclei (blue) at a concentration of 1.43µM. This antibody also gave a positive result in 4% PFA fixed (10 min) Hek293 cells at 1µg/ml, and in 100% PFA fixed (5 min) MCF7 cells at 1µg/ml.
