Here are 2 proposals:

The AllFam database is a resource for classifying allergens into protein families. It is based on allergen data from the Allergome database, the currently most comprehensive collection of allergen data, and on protein family data from the Pfam database.

The WHO/IUIS Allergen Nomenclature Sub-committee is responsible for maintaining and developing a unique, unambiguous and systematic nomenclature for allergenic proteins. The systematic nomenclature is based on the Linnean system and is applied to all allergens. The committee maintains an allergen database that contains approved and officially recognized allergens. The database can be accessed on this website. No other form or system of allergen nomenclature is recognized by the WHO or the IUIS

Dear Prof. Staffan Palm,

Thank you so much for your valuable information. I will go through Allfam database and hope it will be useful for my research.

With Warm Regards
