Structure of the house dust mite allergen Der f 2: Implications for function and molecular basis of IgE cross-reactivity
Overview
The X-ray structure of the group 2 major allergen from Dermatophagoides, farinae (Der f 2) was determined to 1.83 A resolution. The overall Der f 2, structure comprises a single domain of immunoglobulin fold with two, anti-parallel beta-sheets. A large hydrophobic cavity is formed in the, interior of Der f 2. Structural comparisons to distantly related proteins, suggest a role in lipid binding. Immunoglobulin E (IgE) cross-reactivity, between group 2 house dust mite major allergens can be explained by, conserved surface areas representing IgE binding epitopes.
