Vicilin

Vicilin is a globulin associated with legumin. It is used as a storage protein and commonly found in plants like pea or lentil.[1][2][3] It has been suggested to be an allergen in allergic reactions to peas.[4] Besides considered as an allergen, vicilin also considered as a class of protein that benefits plants by its ability to act against fungal activities and microbials.

Major Vicilin Allergens[7]
  1. Ana o 1 in cashew nut
  2. Ara h 1 in peanut
  3. Jug r 2 in walnut
  4. Cor a 11 in hazelnut

Vicilins have similar amino acid sequences and cross-reactivity happen between vicilin allergens. [7]
