Purification and characterization of a novel allergenic walnut vicilin-like protein

ABSTRACT: Walnuts are potent inducers of food allergic symptoms. So far, five allergens were identified, among those, Jug r 2 belonging to the vicilin family. Based on the identification of an IgE-reactive clone from a cDNA library in 1999 (Teuber et al.), the sequence fragment of Jug r 2 was determined. However, only limited data is known about the natural form of the protein. Therefore, this study aimed to purify and characterize the natural Jug r 2. During the study we identified another vicilin with both, higher sequence identity to vicilins from related species and IgE cross reactivity as compared to Jug r 2.

Walnuts are ranked high in the list of the culprit foods inducing severe allergic reactions. Jug r 2 has been identified as a major allergen in common walnut by cDNA cloning from a somatic cell line. So far, studies were performed on the allergenic activity of recombinant Jug r 2, yet there is still no evidence about the physicochemical characteristics of the natural allergen. Therefore, we aimed to purify and deeply characterize natural Jug r 2 and to assess IgE cross-reactivity among vicilins  ...[more]
