Forms pore that permeabilize the cell membrane. Promotes efflux of calcium from synaptosomes, causes hemolysis, and dissipates voltage gradients across muscle membrane. Potently inhibits the growth of bacteria, yeast and Leishmania. May function both in the prey capture strategy as well as protection from infectious organisms arising from prey ingestion (By similarity). Expressed by the venom gland.
