CC   -!- FUNCTION: Amphipathic peptide that shows no antibacterial activity even
CC       at 50 uM but shows a low hemolytic activity against human erythrocytes.
CC       {ECO:0000269|PubMed:22342498}.
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.
CC   -!- SIMILARITY: Belongs to the non-disulfide-bridged peptide (NDBP)
CC       superfamily. Short antimicrobial peptide (group 4) family.
CC       {ECO:0000305}.
