Application Note

Rubratoxin A inhibits protein phosphatase 2A (PP2A) in a competitive manner (Ki: 28.7 nM, IC₅₀: 6.1-15.1 nM), however it does not inhibit protein phosphatases, such as PP1A and PP2B.
Rubratoxin A shows cytotoxicity in cultured mammalian cells (IC₅₀: around 15 µM) and induces overphosphorylation of PP2A substrate proteins.
