Has hemolytic activity against bovine erythrocytes at nanomolar concentrations in vitro. Promotes active pleurotolysin B (PlyB)-dependent permeabilization of membranes rich in cholesterol and sphingomyelin. May play an important role in the initial phase of fungal fruiting. Monomer. Expression begins during formation of the primordia, increases remarkably as the fruiting bodies develop and declines as they mature. Belongs to the aegerolysin family.
