In N/N1003A cells, okadaic acid (10 nM) decreased total phosphatase activity by 20% and mainly inhibited PP-2A activity, while okadaic acid (100 nM) reduced 81% total phosphatase activity and inhibited PP-1 and PP-2A activity.

Abstract: Okadaic acid (OA) is one of the most frequent and worldwide distributed marine toxins. It is easily accumulated by shellfish, mainly bivalve mollusks and fish, and, subsequently, can be consumed by humans causing alimentary intoxications.

It was previously demonstrated as a non-TPA-type tumor promoter and then as a cell-permeable, potent and specific inhibitor of serine/threonine protein phosphatases 1 and 2A.

It is a potent tumour promoter that is not an activator of protein kinase C, but is a powerful inhibitor of protein phosphatases-1 and -2A (PP1 and PP2A) in vitro. Okadaic acid (OA) is one of the diarrheic shellfish poisons (DSP) produced by the dinoflagellate genera Dinophysis and Prorocentrum. There are a number of chemically different toxins associated with DSP. They are lipophilic and polyether compounds and can be divided into three main groups: EuroProxima Okadaic Acid is a competitive enzyme immunoassay for quantitative analysis of domoic acid in scallop, mussel and oyster samples. General information: High concentrations of shellfish toxins can accumulate in filter feeders such as clams, mussels, and … 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.Okadaic is derived from the name of a Japanese educator Yaichiro Okada. When the structure of okadaic acid was elucidated in 1981, Paul Scheuer at the Okadaic acid is a marine sponge toxin which potently inhibits certain serine/threonine protein phosphatases.

Okadaic-acid, a 38-carbon fatty acid isolated from the black sponge Halichondria okadai , can stimulate lipolysis by promoting the phosphorylation of several proteins in adipocytes.
