アプリケーション Abreviews 特記事項
ICC 1/200.
ICC/IF 1/100.
WB Use at an assay dependent concentration. Predicted molecular weight: 331 kDa.
IHC-Fr 1/10.
  • 追加情報Is unsuitable for IHC-P.
  • ターゲット情報

    • 機能Major 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.
    • 組織特異性Isoform DPI is apparently an obligate constituent of all desmosomes. Isoform DPII resides predominantly in tissues and cells of stratified origin.
    • 関連疾患Keratoderma, 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
    • 配列類似性Belongs to the plakin or cytolinker family.
      Contains 17 plectin repeats.
      Contains 1 SH3 domain.
      Contains 6 spectrin repeats.
    • ドメインIts 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.
    • 翻訳後修飾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).
    • 細胞内局在Cell 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).

    • ab16434 staining A431 cells by ICC/IF. Cells were methanol fixed and blocked in 10% serum for 1 hour at 25°C. The primary antibody was diluted 1/100 (PBS+10%FBS) and incubated with the sample for 1 hour at 25°C. An Alexa Fluor® 488 conjugated goat anti-mouse antibody, diluted 1/1500, was used as the secondary.

    • ab16434 staining Desmoplakin I+II in rat glial cultured cells by ICC/IF (Immunocytochemistry/immunofluorescence). Cells were fixed with paraformaldehyde and blocked with 1% serum for 10 minutes at 25°C. Samples were incubated with primary antibody (1/200 in PBS + 5% serum) for 2 hours at 25°C. An Alexa Fluor® 488-conjugated donkey anti-mouse IgG polyclonal (1/300) was used as the secondary antibody.
