    PHYSICAL PROPERTIES
    STRUCTURE
    motifs/domains
  • an intracellular anchor (IA) region, necessary for complex formation with CTNND1, and to maintain free DSG3 at the cell surface before it is integrated into desmosomes
    • conjugated GlycoP
    HOMOLOGY
    Homologene
    FAMILY
  • cadherin superfamily of calcium dependent cell-adhesion molecule
    • CATEGORY adhesion , antigen
    SUBCELLULAR LOCALIZATION     plasma membrane,junction,desmosome
        intracellular
    intracellular,cytoplasm
    basic FUNCTION
  • required for cell adhesion and desmosome formation
  • critical for development of the epidermis and physiologic terminal differentiation of keratinocytes
  • DSG2 is less important than DSG3 for keratinocyte cohesion
    • CELLULAR PROCESS cell communication
