This antibody binds mouse Dsg3 and also shows reactivity for human Dsg3. It does not show any affinity towards Dsg1. AK23 recognizes a calcium-dependent conformational epitope on Dsg3, which consisted of the V3, K7, P8, and D59 Dsg3-specific residues that formed the adhesive interface between juxtaposed Dsg.
Desmoglein 3 (Dsg3), also known as Cadherin family member 6 (CDHF6), is a member of the desmosomal cadherin family and plays a critical role in cell-cell adhesion. It is predominately expressed in stratified squamous epithelium, including the skin, oral mucosa, and esophagus. Desmoglein 3 has been characterized as the auto-antigen of pemphigus vulgaris (PV), a life-threatening autoimmune disease. Binding of anti-Desmoglein 3 autoantibodies causes the loss of cell-cell adhesion, which clinically manifests as blisters on the skin and oral mucosa, and histologically as suprabasilar acantholysis.
