TranscriptomicsProtein phosphatase 2A protects centromeric sister chromatid cohesion during meiosis I
Segregation of homologous maternal and paternal centromeres to opposite poles during meiosis I depends on post-replicative crossing over between homologous non-sister chromatids, which creates chiasmata and therefore bivalent chromosomes. Destruction of sister chromatid cohesion along chromosome arm...

ProteomicsHeLa phosphoproteome regulated by PP2A related proteins
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...

ProteomicsPhosphoproteomic Effects of Acute Depletion of PP2A Regulatory Subunit Cdc55
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...

ProteomicsPhosphorylation dynamics in a flg22-induced, G-protein dependent network reveals the RGS1 phosphatase
The Microbe Associated Molecular Pattern flg22 is recognized in a FLAGELLIN-SENSITVE 2-dependent manner in root tip cells. Here, we show a rapid and massive change in protein abundance and phosphorylation state of the Arabidopsis root cell proteome in wildtype and a mutant deficient in heterotrimer...

TranscriptomicsIntegrative transcriptome profiling of cognitive aging and its preservation through Ser/Thr protein phosphatase regulation
Environmental enrichment has been reported to delay or restore age-related cognitive deficits, however, a mechanism to account for the cause and progression of normal cognitive decline and its preservation by environmental enrichment is lacking. Using genome-wide SAGE-Seq, we provide a global assess...

TranscriptomicsTargeting c-MYC by antagonizing PP2A inhibitors in breast cancer
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.

ProteomicsMapping the substrate landscape of protein phosphatase 2A catalytic subunit PPP2CA
Protein phosphatase 2A (PP2A) is an essential Ser/Thr phosphatase that regulates a plethora of cellular processes. PP2A operates as a holoenzyme complex, comprising one each of the scaffolding (A), regulatory (B) and catalytic (C) subunits. PPP2CA is the principal catalytic subunit of the PP2A holoe...

ProteomicsCytokinetic Abscission in Toxoplasma gondii is governed by Protein Phosphatase 2A and the Daughter Cell Scaffold Complex
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,...
