SDAP is a Web server that integrates a database of allergenic proteins with various computational tools that can assist structural biology studies related to allergens. SDAP is an important tool in the investigation of the cross-reactivity between known allergens, in testing the FAO/WHO allergenicity rules for new proteins, and in predicting the IgE-binding potential of genetically modified food proteins. Using this Internet service through a browser, it is possible to retrieve information related to an allergen from the most common protein sequence and structure databases (SwissProt, PIR, NCBI, PDB), to find sequence and structural neighbors for an allergen, and to search for the presence of an epitope other the whole collection of allergens.

We use the IUIS nomenclature and allergens in SDAP as the official set of allergens, as these allergens have been reviewed by a committee of experts in the field. However, we also included other proteins in SDAP when they were listed in an allergen data base at the time of establishing SDAP. We keep these non-IUIS allergens in SDAP (clearly marked as non-IUIS) as a service for the allergen researchers who are exploring and studying proteins that might have a potential allergenic response. In most cases these proteins can be searched in literature data bases for additional information.

The SDAP project is supported by grants from the National Institute of Health (2R56AI064913), the U.S. Environmental Protection Agency under a STAR Research Assistance Agreement (No. RD 834823), the National Institute of Health (1RO1AI165866-01), and by the Margaret Maccallum Gage and Tracy Davis Gage foundation.
