Probably forms pores in target membranes. Has antibacterial activity against Gram-positive bacteria S.aureus NBRC 13276 (MIC=25-50 uM) and B.subtilis NBRC 3009 (MIC=1.3-2.5 uM) but not against Gram-negative bacterium E.coli NBRC 3972. Probably forms a helical membrane channel in the prey. Expressed by the venom gland. Amidated. Belongs to the non-disulfide-bridged peptide (NDBP) superfamily. Short antimicrobial peptide (group 4) family.
