As it turns out, in the brain it hyperphosphorylates tau, which causes it to tangle. Okadaic Acid (sodium salt) solution in methanol reference standards available online at LGC Standards, for food and beverage analysis. Okadaic acid is a potent inhibitor of protein phosphatase 1/2A with IC50 values of 19 nM and 0.2 nM for protein phosphatase 1 and protein phosphatase 2A, respectively . Protein phosphatase 1 (PP1) and protein phosphatase 2A (PP2A) are two major mammalian serine/threonine protein phosphatases and are activated in response to Ca2+ cascades as well as increased protein kinase A activity . Okadaic acid is a toxic polyether compound of a C 38 fatty acid (Fig. 1).It is isolated from the black sponge, Halichondria okadai (Kadota), however, it is thought to be produced by marine dinoflagellates that attach to the black sponge.

- Mechanism of Action & Protocol. Okadaic acid is a marine sponge toxin which potently inhibits certain serine/threonine protein phosphatases. This cell permeable inhibitor targets the multiple isoforms of PP1 (IC50 = 10-50 nM), both isoforms of PP2A (IC50 = 0.5 nM) and PP3 (IC50 Okadaic Acid mimics the effects of insulin, enhances transmitter release at neuromuscular junctions, causes vasodilation and is a very potent tumor promoter. Okadaic acid is an extremely useful tool for studying cellular processes that are regulated by phosphorylation.

Okadaic acid is a causative agent of diarrhetic shellfish poisoning isolated from the sponge Halichondria Okadai. Okadaic Acid exhibits various activities as follows: Contractile effect on smooth muscles in Ca 2+ free solution. Non-TPA type promoting agent of carcinogenesis. Okadaic acid is extracted from black sponges of the genus Halichondria. Okadaic acid is a non-comepetitive, selective and reversible serine/threonine-specific protein phosphatases 1 (PP1), PP2A and PP3 inhibitor with IC50s of 10-15 nM, 0.5 nM and 4 nM, respectively. Okadaic acid eliminate metazoan symbionts/parasites by apoptosis.

Okadaic acid is an inhibitor of the serine/theorine protein phosphatases PP1 (IC 50 = 15-20 nM) and PP2A (IC 50 = 0.1 nM), exhibiting much greater activity towards the latter. PP2A is completely inhibited at 1-2 nM, compared to greater than 1 µM for PP1 (1).
