Has potent antibacterial activity against Gram-positive bacteria M.luteus, B.thuringiensis, S.aureus and B.subtilis, but not Gram-negative bacteria. Shows a weak cytotoxicity effect against mammalian cell lines and relatively low hemolytic activity against human erythrocytes. Probably forms a helical membrane channel in the prey. Expressed by the venom gland. Amidated. A fragment comprising residues 4-17 has been detected in venom but it is unclear whether it has a physiological role or is simply due to degradation. Belongs to the non-disulfide-bridged peptide (NDBP) superfamily. Short antimicrobial peptide (group 4) family.
