[[http://www.uniprot.org/uniprot/3SA3_NAJAT 3SA3_NAJAT]] Basic protein that binds to cell membrane and depolarizes cardiomyocytes. This cytotoxin also possesses lytic activity on many other cells, including red blood cells (PubMed:8182052). Interaction with sulfatides in the cell membrane induces pore formation and cell internalization. Cytotoxicity is due to pore formation, and to another mechanism independent of membrane-damaging activity. When internalized, it targets the mitochondrial membrane and induces mitochondrial swelling and fragmentation. It inhibits protein kinases C. It binds to the integrin alpha-V/beta-3 (ITGAV/ITGB3) with a moderate affinity (PubMed:16407244). It also binds with high affinity to heparin (PubMed:17685633).<ref>PMID:15922335</ref> <ref>PMID:16263708</ref> <ref>PMID:16407244</ref> <ref>PMID:17714752</ref> <ref>PMID:8182052</ref> <ref>PMID:8448165</ref> <ref>PMID:9245415</ref>
