UniProtKB description:  Pore-forming toxin that defensively acts against parasitic microorganisms by forming pores in sphingomyelin-containing membranes (PubMed:9478988, PubMed:12676961). Has hemolytic activity and is also cytotoxic to spermatozoa of some species of invertebrates and many species of vertebrates and to amphibian larvae, guinea pig polymorphonuclear leukocytes, chicken fibroblasts, normal spleen cells and various tumor cells (PubMed:10684578). Is lethal for various species of reptiles, amphibian, birds and mammals. Induces smooth muscle contraction (PubMed:9210594). It binds sphingomyelin and induces hemolysis in the same manner as lysenin-related protein 2, and is 10-fold more effective than lysenin-related protein 1 (PubMed:15274631).
