Amphipathic peptide that exhibits extensive cytolytic activities against both prokaryotic and eukaryotic cells. Is more potent against Gram-positive bacteria (lethal concentration (LC)=0.25-2.9 uM) than against Gram-negative bacteria (LC=6.2->50 uM), and fungi ((LC)=14.1->50 uM). Shows hemolytic activity against rabbit erythrocytes (37.7% of inhibition at 6.25 uM) and cytolysis against rat dorsal root ganglions. In vivo, intravenous injection into mice tail provokes uncomfortable symptoms with a death rate of 12.5%. Forms a helical membrane channel in the prey. Expressed by the venom gland. Belongs to the non-disulfide-bridged peptide (NDBP) superfamily. Short antimicrobial peptide (group 4) family.
