CC   -!- FUNCTION: Cytotoxin and helminthotoxin with low-efficiency ribonuclease
CC       activity. Possesses a wide variety of biological activities. Exhibits
CC       antibacterial activity (By similarity). {ECO:0000250}.
CC   -!- SUBUNIT: Interacts with bacterial lipopolysaccharide (LPS) and
CC       lipoteichoic acid (LTA). In vitro interacts with phospholipid bilayers.
CC       {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Secreted {ECO:0000250}. Note=Located in the
CC       matrix of eosinophil large specific granule, which are released
CC       following activation by an immune stimulus. {ECO:0000250}.
CC   -!- SIMILARITY: Belongs to the pancreatic ribonuclease family.
CC       {ECO:0000305}.
