InterPro domain: IPR024949

This family consists of a number of plant proteins that are structurally related [ 1 , 2 , 3 ] and seem to be involved in pathogen defence response. These proteins include:

• Bet v I, the major pollen allergen from white birch. Bet v I is the main cause of type I allergic reactions observed in early spring.
• Aln g I, the major pollen allergen from alder.
• Api G I, the major allergen from celery.
• Car b I, the major pollen allergen from hornbeam.
• Cor a I, the major pollen allergen from hazel.
• Mal d I, the major pollen allergen from apple.
• Asparagus wound-induced protein AoPR1.
• Kidney bean pathogenesis-related proteins 1 and 2.
• Parsley pathogenesis-related proteins PR1-1 and PR1-3.
• Pea disease resistance response proteins pI49, pI176 and DRRG49-C.
• Pea abscisic acid-responsive proteins ABR17 and ABR18.
• Potato pathogenesis-related proteins STH-2 and STH-21.
• Soybean stress-induced protein SAM22.
• Major strawberry allergen proteins Fra a 1-2, 1-3 and 1.04 to 1.08
