Scientific Background : A naturally occurring polyether marine toxin. Potent and selective inhibitor of protein phosphatases inhibiting PP2A completely at 1nM and PP1 at higher concentrations, while PP2C is not inhibited. It is an extremely useful tool for studying cellular protein phosphorylation (2). Induces apoptosis in a variety of cell types (3). Activates atypical protein kinase isotypes and induces insulin-like effects in adipocytes (4).
