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.
About this Structure
1XWV is a Single protein structure of sequence from Dermatophagoides farinae with PE3 and XPE as ligands. Full crystallographic information is available from OCA.
