[ | [https://www.uniprot.org/uniprot/3SAN_NAJAT 3SAN_NAJAT] Basic protein that bind to cell membrane and depolarizes cardiomyocytes. This cytotoxin also shows lytic activities, on many other cells including red blood cells. Interaction with sulfatides in the cell membrane induces pore formation and cell internalization and is responsible for cytotoxicity in cardiomyocytes. It targets the mitochondrial membrane and induces mitochondrial swelling and fragmentation. Inhibits protein kinases C (By similarity). It binds to the integrin alpha-V/beta-3 with a moderate affinity (PubMed:16407244).<ref>PMID:16407244</ref> | ||
