Short name: Envoplakin

Family relationships

None.

Description

Envoplakin belongs to the plakin family of cytolinker proteins, which also includes desmoplakin, plectin, periplakin and BPAG1 (bullous pemphigoid antigen) [PMID: 12432088]. It was originally identified as components of the cornified envelope (CE) [PMID: 6200236, PMID: 8707850]. It is also found in the desmosomes of keratinocytes and other epithelial cells [PMID: 12432088]. Envoplakin and periplakin can form stable heterodimers that localise to desmosomes and the plasma membrane in a manner dependent on the periplakin N terminus [PMID: 18166659]. The C termini of envoplakin and periplakin bind intermediate filaments, and this interaction may provide the link between the cytoskeleton and the CE that confers mechanical stability to corneocytes [PMID: 12432088, PMID: 18166659].
