技术指标

Our Abpromise guarantee covers the use of ab71689 in the following tested applications.

The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.

  • 纯度70 - 90% by HPLC.

  • 形式Liquid
  • 补充说明

    - First try to dissolve a small amount of peptide in either water or buffer. The more charged residues on a peptide, the more soluble it is in aqueous solutions.
    - If the peptide doesn’t dissolve try an organic solvent e.g. DMSO, then dilute using water or buffer.
    - Consider that any solvent used must be compatible with your assay. If a peptide does not dissolve and you need to recover it, lyophilise to remove the solvent.
    - Gentle warming and sonication can effectively aid peptide solubilisation. If the solution is cloudy or has gelled the peptide may be in suspension rather than solubilised.
    - Peptides containing cysteine are easily oxidised, so should be prepared in solution just prior to use.

  • 功能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.
  • 组织特异性Isoform DPI is apparently an obligate constituent of all desmosomes. Isoform DPII resides predominantly in tissues and cells of stratified origin.
  • 疾病相关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
  • 序列相似性Belongs to the plakin or cytolinker family.
    Contains 17 plectin repeats.
    Contains 1 SH3 domain.
    Contains 6 spectrin repeats.
  • 结构域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.
  • 翻译后修饰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).
  • 细胞定位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).
