WebSeveral group members are involved in the molecular pathology of genetic and acquired human diseases including epidermolysis bullosa, ectodermal dysplasia, bullous pemphigoid or Alzheimer disease. An extensively investigated member is collagen XVII, a keratinocyte surface protein, which attaches the epidermis to the basement membrane in the skin. WebThis gene encodes the alpha chain of type XVII collagen. Unlike most collagens, collagen XVII is a transmembrane protein. Collagen XVII is a structural component of …
WebBullous pemphigoid (BP), an autoimmune subepidermal blistering skin disease, demonstrates tense blisters with or without widespread erythema, blistering along the lamina lucida, immunoglobulin G and/or complement deposits at the basement membrane zone, and the presence of circulating autoantibodies against hemidesmosomal molecules. WebType XVII collagen, also known as 180-kDa bullous pemphigoid antigen, is a type II transmembrane collagen.
