The fraction containing this toxin and CfTX-A shows potent hemolytic activity (PubMed:24403082). This fraction causes minor effects on the cardiovascular system of anesthetized rats (at 25 ug/kg), since it has no significant effects on heart rate but produces relatively small increases in mean arterial pressure (PubMed:24403082). Oligomer. Forms a membrane channel in the prey. Nematocytes. Contains 2 disulfide bonds. The fraction containing this toxin and CfTX-B does not cross-react with CfTX-1 and CfTX-2 antibodies. Found after both pressure and chemical disruption of nematocysts. Belongs to the jellyfish toxin family. Type II subfamily.
