Desmoglein 3 Antibody-HuProt Validated clone DSG3/2838 recognizes Desmoglein 3, a calcium-dependent desmosomal cadherin encoded by the DSG3 gene on chromosome 18q12.1. Desmoglein 3, commonly referred to as DSG3 in the literature, is a single-pass transmembrane glycoprotein localized to desmosomes at the plasma membrane of stratified epithelial cells where it mediates strong intercellular adhesion. This Desmoglein 3 antibody is HuProt validated using a human proteome microarray platform containing more than 19,000 full-length human proteins, supporting high target specificity. DSG3 antibody, also known as Desmoglein 3 antibody, is widely used in research focused on epithelial biology, mucocutaneous integrity, and autoimmune blistering disorders.
Desmoglein 3 belongs to the cadherin superfamily and serves as a core structural component of desmosomal junctions. Its extracellular cadherin repeats mediate calcium-dependent homophilic adhesion between adjacent epithelial cells, while its cytoplasmic domain associates with desmosomal plaque proteins including Plakoglobin and Desmoplakin. Through these interactions, Desmoglein 3 anchors keratin intermediate filaments to the plasma membrane, reinforcing tissue stability in stratified epithelia subjected to mechanical stress such as skin and mucosal surfaces.
DSG3 expression is most prominent in the basal and suprabasal layers of stratified squamous epithelia, including oral mucosa, esophagus, cervix, and epidermis. In contrast to Desmoglein 1, which is enriched in superficial epidermal layers, Desmoglein 3 is concentrated in deeper epithelial layers and plays a central role in maintaining mucocutaneous cohesion. Autoantibodies targeting Desmoglein 3 are strongly associated with pemphigus vulgaris, where disruption of desmosomal adhesion leads to intraepidermal blister formation. Altered DSG3 expression has also been reported in squamous cell carcinoma and other epithelial malignancies, where changes in desmosomal composition may influence tumor differentiation and progression.
Structurally, Desmoglein 3 contains multiple extracellular cadherin domains, a single transmembrane region, and an intracellular tail that integrates into the desmosomal plaque complex. Beyond its mechanical adhesion function, DSG3 participates in signaling pathways regulating keratinocyte proliferation, differentiation, and epithelial homeostasis. Through proteome-wide HuProt validation and its well-established biological role in desmosomal architecture, Desmoglein 3 remains an important molecular marker in epithelial research.
Optimal dilution of the Desmoglein 3 antibody-HuProt validated clone DSG3/2838 should be determined by the researcher.
A recombinant human partial protein (amino acids 379-491) was used as the immunogen for the Desmoglein 3 antibody-HuProt validated clone DSG3/2838.
Store the Desmoglein 3 antibody at 2-8oC (with azide) or aliquot and store at -20oC or colder (without azide).
