Cell-permeable. Maintains the undifferentiated state of embryonic stem cells. By targeting the PR72/130 subunit of the Ser/Thr phosphatase PP2A, it prevents b-catenin from switching coactivator usage from CBP to p300. The increase in b-cateinin/CBP mediated transcription at the expense of b- cateinin/p300-mediated transcription helps to maintain the murine stem cell pluripotency.
