  • Target

    • FunctionMajor high molecular weight protein of desmosomes. Involved in the organization of the desmosomal cadherin-plakoglobin complexes into discrete plasma membrane domains and in the anchoring of intermediate filaments to the desmosomes.
    • Tissue specificityIsoform DPI is apparently an obligate constituent of all desmosomes. Isoform DPII resides predominantly in tissues and cells of stratified origin.
    • Involvement in diseaseKeratoderma, palmoplantar, striate 2
      Cardiomyopathy, dilated, with woolly hair and keratoderma
      Arrhythmogenic right ventricular dysplasia, familial, 8
      Skin fragility-woolly hair syndrome
      Epidermolysis bullosa, lethal acantholytic
      Cardiomyopathy, dilated, with woolly hair, keratoderma, and tooth agenesis
    • Sequence similaritiesBelongs to the plakin or cytolinker family.
      Contains 17 plectin repeats.
      Contains 1 SH3 domain.
      Contains 6 spectrin repeats.
    • DomainIts association with epidermal and simple keratins is dependent on the tertiary structure induced by heterodimerization of these intermediate filaments proteins and most likely involves recognition sites located in the rod domain of these keratins.
      The N-terminal region is required for localization to the desmosomal plaque and interacts with the N-terminal region of plakophilin 1.
      The three tandem plakin repeat regions in the C-terminus mediate binding to intermediate filaments.
    • Post-translational
      Ser-2849 is probably phosphorylated by a cAMP-dependent protein kinase. Phosphorylation on Ser-2849 probably affects its association with epidermal, simple cytokeratins and VIM intermediate filaments.
      Substrate of transglutaminase. Some glutamines and lysines are cross-linked to other desmoplakin molecules, to other proteins such as keratin, envoplakin, periplakin and involucrin, and to lipids like omega-hydroxyceramide (PubMed:9651377).
    • Cellular localizationCell junction, desmosome. Cytoplasm, cytoskeleton. Cell membrane. Innermost portion of the desmosomal plaque. Colocalizes with epidermal KRT5-KRT14 and simple KRT8-KRT18 keratins and VIM intermediate filaments network (PubMed:12802069). Localizes at the intercalated disk in cardiomyocytes (By similarity).
