Previous studies implicate PP2A in the regulation of the Hippo pathway: while proteomics/RNAi screening show that dSTRIPAK-associated PP2A suppresses the Hippo pathway in Drosophila, PP2A inhibition by okadaic acid induces MOB1-phosphorylation in yeast cells and MST1/2-phosphorylation in HeLa cervical cancer cells32–34. The gene discussed is PTPA; the disease is cervical cancer.
