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). - Information by UniProt

Immunocytochemistry/ Immunofluorescence - Anti-Desmoplakin I+II antibody (ab71690)
ab71690 staining Desmoplakin I+II in HaCat cells. The cells were fixed with 100% methanol (5 min), permeabilized with 0.1% PBS-Tween for 5 minutes and then blocked with 1% BSA/10% normal goat serum/0.3M glycine in 0.1%PBS-Tween for 1h. The cells were then incubated overnight at 4°C with ab71690 at 1µg/ml and ab7291, Mouse monoclonal [DM1A] to alpha Tubulin - Loading Control. Cells were then incubated with ab150081, Goat polyclonal Secondary Antibody to Rabbit IgG - H&L (Alexa Fluor® 488), pre-adsorbed at 1/1000 dilution (shown in green) and ab150120, Goat polyclonal Secondary Antibody to Mouse IgG - H&L (Alexa Fluor® 594), pre-adsorbed at 1/1000 dilution (shown in pseudocolour magenta). Nuclear DNA was labelled with DAPI (shown in blue).
Also suitable in cells fixed with 4% paraformaldehyde (10 min).
Image was acquired with a high-content analyser (Operetta CLS, Perkin Elmer) and a maximum intensity projection of confocal sections is shown.

Predicted band size: 260 , 332 kDa
Observed band size: 238,270 kDa why is the actual band size different from the predicted?
Additional bands at: 110 kDa, 45 kDa. We are unsure as to the identity of these extra bands.
