Opis

General description

Okadaic acid is a polyether fatty acid. It is a marine toxin produced by the genera of Prorocentrum and Dinophysis.

Application

Okadaic acid from Prorocentrum concavum has been used as a phosphatase inhibitor:

• to inhibit protein phosphatase 2 in spermatocytes culture
• to treat SH-SY5Y cells to prevent dephosphorylation to maintain tau
• to treat human embryonic kidney 293T cells (HEK293T) or H4 cells to analyse its effect on fused in sarcoma (FUS) protein

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.

Okadaic acid is a dinoflagellate toxin and an ionophore-like polyether derivative of a 38 carbon, fatty acid.
