CC   -!- FUNCTION: Cationic host defense peptide that have antibacterial
CC       activity by breaking membranes. Is more effective on Gram-positive than
CC       on Gram-negative bacteria. {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Secreted {ECO:0000250}. Target cell membrane
CC       {ECO:0000250}. Note=Forms a helical membrane channel in the prey.
CC       {ECO:0000250}.
CC   -!- TISSUE SPECIFICITY: Expressed by the venom gland. {ECO:0000305}.
CC   -!- SIMILARITY: Belongs to the non-disulfide-bridged peptide (NDBP)
CC       superfamily. Short antimicrobial peptide (group 4) family.
CC       {ECO:0000305}.
