CC -!- FUNCTION: Alpha-amylase/trypsin inhibitor. It could be involved in
CC insect defense mechanisms.
CC -!- SUBUNIT: Subunit of the tetrameric inhibitor.
CC -!- SUBCELLULAR LOCATION: Secreted.
CC -!- TISSUE SPECIFICITY: Developing endosperm.
CC -!- PTM: Five disulfide bonds, which are essential for the inhibitor
CC activity, are probably present. {ECO:0000305}.
CC -!- MISCELLANEOUS: CM proteins would be involved in the cooking quality of
CC pasta.
CC -!- SIMILARITY: Belongs to the protease inhibitor I6 (cereal trypsin/alpha-
CC amylase inhibitor) family. {ECO:0000305}.
