Inhibits protein phosphatase 2A (Ki=0.19 µM) and PP1 (Ki=1.1 µM)1. Displays >500-fold selectivity over PP2B. Suppresses growth and migration of PANC-1 pancreatic cancer cells via phosphorylation and degradation of β-catenin2. Arrests G2/M transition via JNK/Sp1-dependent down-regulation of CDK13. Cell permeable. Warning: Avoid skin contact, may cause skin irritation or blistering.
