CC   -!- FUNCTION: Possesses antifungal activity and is also active on two
CC       tested Gram-positive bacteria but is non-toxic for Gram-negative
CC       bacteria and cultured human cells.
CC   -!- SUBUNIT: Homodimer.
CC   -!- SUBCELLULAR LOCATION: Secreted.
CC   -!- TISSUE SPECIFICITY: Seed specific.
CC   -!- DOMAIN: The presence of a 'disulfide through disulfide knot'
CC       structurally defines this protein as a knottin. {ECO:0000250}.
CC   -!- SIMILARITY: Belongs to the AMP family. {ECO:0000305}.
