UniProtKB description: Basic protein that binds to cell membrane and depolarizes cardiomyocytes. It also shows lytic activities, but 2-fold less important than that of CTX-A4. It binds to the integrin alpha-V/beta-3 (ITGAV/ITGB3) with a moderate affinity. It may interact with sulfatides in the cell membrane which induces pore formation and cell internalization and is responsible for cytotoxicity in cardiomyocytes. It may also target the mitochondrial membrane and induce mitochondrial swelling and fragmentation.
