CC   -!- FUNCTION: Seed storage protein. Might be integrated via inter-chain
CC       disulfide bonds within the glutenin polymer (By similarity).
CC       {ECO:0000250}.
CC   -!- TISSUE SPECIFICITY: Expressed only in developing endosperms. Not
CC       detected in roots, stems or leaves. {ECO:0000269|Ref.1}.
CC   -!- DEVELOPMENTAL STAGE: Expressed between 3 and 22 days post anthesis
CC       (DPA), with a peak between 11 and 15 DPA. {ECO:0000269|Ref.1}.
CC   -!- PTM: Contains disulfide bonds. {ECO:0000305}.
CC   -!- SIMILARITY: Belongs to the prolamin family. {ECO:0000305}.
