Okadaic acid (78111-17-8) is a naturally occurring polyether marine toxin. Potent and selective inhibitor of protein phosphatases inhibiting PP2A completely at 1 nM 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 Okadaic acid activates atypical protein kinase isotypes and induces insulin-like effects in adipocytes.4

Caution: SKIN IRRITANT, TUMOR PROMOTOR. Avoid contact.
