RT   "Nucleotide sequence of a member of the napin storage protein family from
RT   Brassica napus.";
RL   J. Biol. Chem. 262:12202-12208(1987).
CC   -!- FUNCTION: The small, basic, water-soluble napins are one of the two
CC       major kinds of storage proteins synthesized in the seed during its
CC       maturation.
CC   -!- SUBUNIT: The mature protein consists of a small and a large chain
CC       linked by disulfide bonds.
CC   -!- TISSUE SPECIFICITY: Cotyledons and the axis.
CC   -!- DEVELOPMENTAL STAGE: Embryo.
CC   -!- SIMILARITY: Belongs to the 2S seed storage albumins family.
CC       {ECO:0000305}.
