Desmoglein-3

Desmoglein-3 is a is_associated_with::protein that in humans is encoded by the DSG3 is_associated_with::gene.

Function
is_associated_with::Desmosomes are cell-cell junctions between epithelial, myocardial, and certain other cell types. Desmoglein 3 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. This protein has been identified as the autoantigen of the autoimmune skin blistering disease pemphigus vulgaris.

Interactions
Desmoglein 3 has been shown to interact with is_associated_with::PKP3.
