A polyketide, polyether derivative of a C38 fatty acid, it is one of the primary causes of diarrhetic shellfish poisoning (DSP). It is a potent inhibitor of specific protein phosphatases and is known to have a variety of negative effects on cells. It has a role as a marine metabolite, an EC 3.1.3.16 (phosphoprotein phosphatase) inhibitor and a calcium ionophore."}]
