Desmoglein-3

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, along with Desmoglein-1, has been identified as the autoantigen of the autoimmune skin blistering disease pemphigus vulgaris.{{cite journal | vauthors = Hartlieb E, Kempf B, Partilla M, Vigh B, Spindler V, Waschke J | title = Desmoglein 2 is less important than desmoglein 3 for keratinocyte cohesion | journal = PLOS ONE | volume = 8 | issue = 1 | pages = e53739 | date = 2013-01-11 | pmid = 23326495 | pmc = 3543261 | doi = 10.1371/journal.pone.0053739 | bibcode = 2013PLoSO...853739H | doi-access = free }} The mucosal dominant form of pemphigus vulgaris only involves antibodies against Desmoglein-3 and causes mucosal erosions, but no skin lesions. Desmoglein-3 serves as a prognostic marker of Esophageal Squamous Cell Carcinoma (ESCC), and may even be involved in the progression of ESCC.{{cite journal | vauthors = Fang WK, Gu W, Liao LD, Chen B, Wu ZY, Wu JY, Shen J, Xu LY, Li EM | title = Prognostic significance of desmoglein 2 and desmoglein 3 in esophageal squamous cell carcinoma | journal = Asian Pacific Journal of Cancer Prevention | volume = 15 | issue = 2 | pages = 871–6 | date = 2014 | pmid = 24568510 | doi = 10.7314/apjcp.2014.15.2.871 | doi-access = free }}

Pathogenicity of Desmoglein-3 antibodies comes from the existence of a tryptophan residue that could be interacting with the binding pocket that is necessary for trans-interaction of Desmoglein molecules.{{cite journal | vauthors = Spindler V, Rötzer V, Dehner C, Kempf B, Gliem M, Radeva M, Hartlieb E, Harms GS, Schmidt E, Waschke J | title = Peptide-mediated desmoglein 3 crosslinking prevents pemphigus vulgaris autoantibody-induced skin blistering | journal = The Journal of Clinical Investigation | volume = 123 | issue = 2 | pages = 800–11 | date = February 2013 | pmid = 23298835 | pmc = 3561799 | doi = 10.1172/jci60139 }} Such antibodies can lead to the cause of skin disorders like pemphigus vulgaris.

Desmoglein 3 has been shown to interact with PKP3.{{cite journal | vauthors = Bonné S, Gilbert B, Hatzfeld M, Chen X, Green KJ, van Roy F | title = Defining desmosomal plakophilin-3 interactions | journal = The Journal of Cell Biology | volume = 161 | issue = 2 | pages = 403–16 | date = April 2003 | pmid = 12707304 | pmc = 2172904 | doi = 10.1083/jcb.200303036 | hdl = 1854/LU-210987 }}
