产品描述 | Calyculin A is a natural, cell-permeable inhibitor of the serine-threonine protein phosphatases (PP) PP1 and PP2A (IC50s = 0.3-0.7 and 0.5-1 nM, respectively).[1],[2],[3] It is without significant effect against PP2B, PP2C, and PP4.[2] Through its effects on PP1 and PP2A, calyculin A has been shown to either promote or inhibit cancer cell growth in tumor cell lines and animal models.[4],[5] Reference: [1].
