Desmoglein 1 is a protein that in humans is encoded by the DSG1 gene.^[1][2]

Desmosomes are cell-cell junctions between epithelial, myocardial and certain other cell types. Desmoglein 1 is a calcium-binding transmembrane glycoprotein component of desmosomes in vertebrate epithelial cells. Currently, four desmoglein subfamily members have been identified and all are members of the cadherin cell adhesion molecule superfamily. These desmoglein gene family members are located in a cluster on chromosome 18. The protein encoded by this gene has been identified as the autoantigen of the autoimmune skin blistering disease pemphigus foliaceus.^[2]

Interactions

Desmoglein 1 has been shown to interact with PKP3^[3] and PKP2.^[4]
