DSG3
Desmoglein-3 (DSG3) is the desmosomal cadherin of the lower epidermis and mucous membranes, where it dominates over DSG1 and maintains the strong intercellular adhesion that protects stratified squamous epithelia from mechanical stress. DSG3 is best known as the autoantigen of pemphigus vulgaris: IgG autoantibodies against its extracellular cadherin repeats cause suprabasal blistering of skin and mucosa, and circulating anti-DSG3 titers track disease activity. Mouse models deleting Dsg3 reproduce the mucosal blistering phenotype, confirming nonredundant function. Recombinant DSG3 ectodomain serves as the standard substrate for diagnostic ELISA and antigen-specific immunoadsorption approaches in pemphigus.

The EpCAM/TROP1 protein serves as an important homogeneous interacting molecule that promotes direct contact between intestinal epithelial cells (IEC) and intraepithelial lymphocytes (IEL) in the mucosal epithelium. This feature helps establish an immune barrier against mucosal infections. EpCAM/TROP1 Protein, Human (His-SUMO) is the recombinant human-derived EpCAM/TROP1 protein, expressed by E. coli , with N-6*His, N-SUMO labeled tag.
