Description

Desmoglein-3 mediates calcium-dependent cell-cell adhesion in stratified epithelia and serves as the primary autoantigen in pemphigus vulgaris, making it a critical target for antibody development and desmosomal signaling research. This recombinant mouse Dsg3 construct spans residues 50–617, encompassing the extracellular cadherin domains essential for homophilic and heterophilic binding interactions, and its mammalian expression system supports native-like glycosylation and folding required for functional studies. Binding activity has been validated by ELISA, where immobilized Dsg3 at 5 μg/mL bound an anti-DSG3 recombinant antibody with an EC50 of 2.624–3.182 μg/mL, confirming correct epitope presentation suitable for antibody validation, cell adhesion and spreading assays, and integrin-ligand binding studies. With purity exceeding 85% by SDS-PAGE and endotoxin levels below 1.0 EU/μg, this preparation meets the quality thresholds commonly required for cell-based migration and invasion assays investigating desmosomal disruption in autoimmune or metastasis contexts.

Target Background

Function

Component of intercellular desmosome junctions. Involved in the interaction of plaque proteins and intermediate filaments mediating cell-cell adhesion.
