  • 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
  • Sequence similarities
    Belongs to the intermediate filament family.
  • Post-translational
    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.
