Table 3.

Results of two automatic FASTA searches in SDAP that illustrate how to use this site to correctly name a new allergen. While the cedar pollen allergens Jun a 2 and Cry j 2 are very close in sequence (i.e, have a very low expectation (E) value; top table), they are not related to the allergen originally called Jun o 2. This protein, officially named Jun o 4 by the IUIS, is similar to Bet v 4 and other allergens of that sequence family (bottom table).
