Protein phosphatase regulatory subunits are increasingly recognized as promising drug targets. In the absence of an existing drug, inducible degradation provides a means of predicting candidate targets. We here employed auxin-inducible degradation of S. cerevisiae PP2A regulatory subunit Cdc55 in co...

Inhibition of SET by siRNA or SET antagonist and CIP2A by siRNA can downregulate c-MYC and c-MYC target genes. Cells were treated with a SET antagonist (1μMOP449) for 12 hours, or siRNA for 48 hours.

HeLa cells were treated with siRNAs of PP2A related proteins or with okadaic acid, in triplicates. Tryptic digests of extracted proteins were analyzed using a Q Exactive mass spectrometer, before and after TiO2 phosphopeptide enrichment. Data were searched with Mascot via Proteome Discoverer. For ph...

During mitosis, TATA-binding protein(TBP), which remains bound to DNA during mitosis, recruits PP2A and also interacts with a subunit of the condensin complex to allow efficient dephosphorylation and inactivation of condensin near these promoters to inhibit their compaction. These result suggest tha...

The yeast PP2A-Cdc55 Serine/Threonine phosphatase regulates transcription under certain conditions. It is required for full activation of the environmental stress response mediated by the transcription factors Msn2 and Msn4. PP2A-Cdc55 contributes to sustained nuclear accumulation of Msn2 and Msn4 a...

In this study, we discovered that CDK9-mediated, RNAPII-driven transcription is functionally opposed by a protein phosphatase 2A (PP2A) complex that is recruited to transcription sites by the Integrator complex subunit INTS6. PP2A dynamically antagonises phosphorylation of key CDK9 substrates includ...

Cytokinetic abscission is the last step of cell division during which the daughter cells physically separate through the generation of barriers in the form of new plasma membrane or cell wall. While the contractile ring is a prominent structure during cytokinesis in bacteria, fungi and animal cells,...
