De Minimis - 1170 / 3

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 = 4 nM).{21676,21677,21678} It is a very weak inhibitor of PP2B (IC50 > 2 μM) and does not inhibit PP2C or other phosphatases.{21676,21678} Presumably through these actions, okadaic acid is a potent carcinogen and induces tau phosphorylation.{21680,21681} In sponge, okadaic acid plays a role in defense, inducing apoptosis in symbiotic or parasitic annelids.{21679}
