Mechanism of ToxicitySticholysin is a cardiac stimulatory and hemolytic pore-forming protein. Pore formation likely proceeds by membrane binding via a surface rich in aromatic residues, followed by translocation of the N-terminal region to the membrane and, finally, across the bilayer to form a functional pore. Cytolytic effects include red blood cells hemolysis, platelet aggregation and lysis, and cytotoxic and cytostatic effects on fibroblasts. (1)
MetabolismFree toxin may be removed by opsonization via the reticuloendothelial system (primarily the liver and kidneys) or it may be degraded through cellular internalization via the lysosomes. Lysosomes are membrane-enclosed organelles that contain an array of digestive enzymes, including several proteases.
