Amphipathic peptide that exerts potent selective cytotoxic and antiproliferative activity against three different prostate cancer cell lines (IC(50)=4.4-7.8 uM), compared to non-tumorigenic cells (IC(50)=59.7 in Vero and 62.5 in HUVEC cells). This peptide possibly exerts its cytotoxic activity through a necrotic mode of cell death. Forms a helical membrane channel in the prey. Expressed by the venom gland. Only shows diminished hemolytic activity against sheep erythrocytes. Does not induce cell death through apoptosis and consequently is not acting upon an intracellular target. Belongs to the non-disulfide-bridged peptide (NDBP) superfamily. Long chain multifunctional peptide (group 2) family.
