PerfectionPeptide P3 consists on a sequence of desmoglein specifically designed to compete for the binding site between desmocollin and desmoglein in the outermost layers of the stratum corneum. Genetic disorders associated with desmocollin gene mutations include Carvajal syndrome, striate palmoplantar keratoderma, Naxos disease, and arrhythmogenic right ventricular cardiomyopathy. Anti-desmoglein (Dsg) 1 and Dsg3 IgG autoantibodies in pemphigus foliaceus and pemphigus vulgaris cause blisters through loss of desmosomal adhesion. This desmoglein-specific SP consists of just one amino acid loop identical to the ones used in the TP. They play an important role in epithelial adhesion. AU - Amagai, Masayuki. Avoid using sera exhibiting a high level of lipemia, hemolysis, icterus or microbial growth. No anticoagulants, or preservatives should be added. The transient expression of desmoglein in L-cell lines expressing plakoglobin mRNA resulted in the formation of a complex between plakoglobin and desmoglein and in the accumulation of plakoglobin protein. Here we use structure-function analysis … Desmoglein-3 is a protein that in humans is encoded by the DSG3 gene. Neither IgA anti‐desmoglein 3 nor IgG anti‐desmoglein 1/3 autoantibodies were present. Recently, we have … In cardiac muscle, these regions are specialized regions known as intercalated discs. PY - 2000/6/17. They find that Dsc2a is necessary and sufficient to organise desmosome-like structures and to produce strong adhesions that inhibit cell migration. Desmosomes are critical elements of intercellular junctions; they are punctate structures made up of transmembrane desmosomal cadherins termed desmoglein-2 (Dsg2) and desmocollin-2 (Dsc2) that affiliate with the underlying intermediate filaments via linker proteins to provide mechanical strength to epithelia. It is thought that they may have different adhesive properties that are required at different levels in stratified epithelia or that they have specific functions in epithelial differentiation. Previous studies demonstrate that E-cadherin (Ecad), an adhesive protein that interacts in both trans (between opposing cells) and cis (on the same cell surface) conformations, facilitates desmosome assembly via an unknown mechanism. T2 - A comparative immunohistochemical and molecular study. Background— This study aimed to evaluate the prevalence and type of mutations in the major desmosomal genes, Plakophilin-2 (PKP2), Desmoglein-2 (DSG2), and Desmocollin-2 (DSC2), in … Here, we observed that non-desmoglein (Dsg) AuAbs in the sera of patients with Dsg1/3 AuAb–negative acute PV are pathogenic, because IgGs from these individuals induced skin blistering in neonatal mice caused by suprabasal acantholysis. Previous studies demonstrate that E-cadherin (Ecad), an adhesive protein that interacts in both trans(between opposing cells) and cis(on the same cell surface) conformations, facilitates desmosome … Using single-molecule force spectroscopy, the authors then show that Dsc2a forms the homophilic bonds that are required for desmosome formation, whereas Dsg2 forms heterophilic bonds with Dsc2a that may be important for desmosome stability.
