CC   -!- FUNCTION: Seed storage protein. Serves as a source of nitrogen, carbon,
CC       and sulfur for the young developing seedling (By similarity).
CC       {ECO:0000250|UniProtKB:P80356}.
CC   -!- SUBUNIT: Monomer. {ECO:0000250|UniProtKB:P80356}.
CC   -!- SUBCELLULAR LOCATION: Vacuole, aleurone grain {ECO:0000250}.
CC       Note=Protein bodies inside vacuoles. {ECO:0000250}.
CC   -!- ALLERGEN: Causes an allergic reaction in human. Avenins are one of the
CC       causes of celiac disease, also known as celiac sprue or gluten-
CC       sensitive enteropathy (By similarity). {ECO:0000250}.
CC   -!- SIMILARITY: Belongs to the gliadin/glutenin family. {ECO:0000255}.
