General description

Desmoglein-1 (DSG1) is a transmembrane glycoprotein belonging to the family of cadherins. It is one of the main structural components of desmosomal junctions which are abundant in tissues undergoing frequent mechanical stress, such as the heart, epidermis, lymphatic endothelial cells, and meninges. The desmoglein-1 subtype is highly expressed in the epidermis. Like other cadherins, desmoglein-1 contains multiple calcium binding sites and a cell-adhesion recognition site which facilitates intercellular adhesions. Desmoglein-1 is regulated by calcium and PKCα signaling, and is also coupled to intermediate filaments of the cytoskeleton. Desmosomes play a critical role in cell and tissue stability, and may contribute to the progression of cancer.

Cell Structure
Anti-Desmoglein-1, clone 32-2B detects levels of Desmoglein-1 proteins & has been published & validated for use in WB, IF, IHC & ICC.
Immunohistochemistry Analysis: A 1:1,000 dilution from a representative lot detected Desmoglein-1 in human tonsil tissues.

Immunofluorescence Analysis: A 1:1,000 dilution from a representative lot detected Desmoglein-1 in human tonsil tissues.

Western Blot Analysis: A representative lot from an independent laboratory detected Desmoglein-1 in bovine epidermal desmosomal cores and in human keratinocyte cell lysates. (Vilela, M. J., et al. (1995). J Cell Sci. 108(Pt 4):1743-1750.).

Desmosomes are intercellular adhesive junctions that occur in almost all epithelia and should therefore be useful as epithelial markers in tumour diagnosis. Here, we describe a monoclonal antibody, 32-2B, to a major desmosomal glycoprotein (dgl) which reacts with human tissues...
