CC   -!- FUNCTION: Exhibits unusual shark repellent and surfactant properties.
CC       Forms voltage-dependent, ion-permeable channels in membranes. At high
CC       concentration causes cell membrane lysis.
CC   -!- SUBUNIT: Monomer. In aqueous solution exists as a tetramer.
CC   -!- SUBCELLULAR LOCATION: Secreted. Target cell membrane. Note=Forms a
CC       helical membrane channel in the prey.
CC   -!- SIMILARITY: Belongs to the pardaxin family. {ECO:0000305}.
