Biochem/physiol Actions

Dinoflagellate toxin and an ionophore-like polyether derivative of a 38 carbon, fatty acid. Readily enters cells. Inhibitor of type 1 and type 2A protein phosphatases. Does not inhibit tyrosine phosphatases, alkaline phosphatases or acid phosphatase. Known tumor promotor. Used to study various cellular processes including cell cycle, apoptosis, nitric oxide metabolism and calcium signaling.
