Dinophysistoxin-2 (DTX-2) is a potent marine biotoxin produced by certain species of the dinoflagellate genus Dinophysis. It belongs to the okadaic acid group of toxins, which are responsible for diarrhetic shellfish poisoning (DSP) when contaminated shellfish are consumed. DTX-2 inhibits protein phosphatases, leading to cellular disruptions and gastrointestinal symptoms. It is a critical target in marine toxicology and food safety monitoring, as it poses significant health risks and economic impacts on the shellfish industry.
