Food Allergy: 2S Seed Storage Proteins

What are they?

They are water soluble proteins found in a wide variety of nuts, seeds, fruit and vegetables. As allergenic proteins go, they are very stable, which means they are not easily damaged by extreme changes in temperature or pH due to their small size and compact structure. This means that the proteins ability to trigger and allergic reaction in a sensitised individual would not be hindered by cooking, freezing, digestion or in many cases food processing.

Their function in plants is as a source of nutrients during germination and growth of seedlings. They are also thought to also to play a role in defence against plant pathogens.

2S albumins are a part of the prolamin superfamily; other allergenic proteins included in this superfamily are lipid transfer proteins and prolamin storage proteins of cereals.
