ProteomicsAurora B opposes PP1 function in mitosis through phosphorylation of the conserved RVxF binding motif in PP1 regulatory proteins
Protein phosphatase 1 (PP1) is a highly conserved protein phosphatase that opposes the actions of a diverse set of Ser-Thr protein kinases by controlling the majority of serine-threonine (Ser-Thr) dephosphorylation reactions in eukaryotes. PP1 gains substrate specificity through binding to a large n...

TranscriptomicsMapping and characterization of promoter-binding sites of protein phosphatase 1
Protein phosphatase 1 (PP1) is a Ser/Thr phosphatase that has been implicated in many key cellular functions including transcriptional regulation. Due to its involvement these many processes, it becomes difficult to directly link PP1 to transcriptional regulation on the chromatin level as no direct ...

TranscriptomicsExpression profiling of HeLa Tet-off cells expressing Flag-tagged version of WT NIPP1 or PP1 binding mutant of NIPP1.
NIPP1, an established interactor of protein phosphatase 1 (PP1), is implicated in PRC2-mediated regulation of gene expression. Here, we explore whether PP1 associated with NIPP1 is involved in NIPP1-mediated regulation of genes. Therefore, we generated Hela Tet-off (HTO) cell lines that stably and i...

ProteomicsPPP1R2 (Inhibitor 2) stimulates protein phosphatase PP1 through stabilisation of dynamic subunit interactions
Protein Ser/Thr phosphatase PP1 is always associated with one or two regulatory subunits or RIPPOs. One of the earliest evolved RIPPOs is PPP1R2, also known as Inhibitor-2. Since its discovery nearly 5 decades ago, PPP1R2 has been variously described as an inhibitor, activator or (metal) chaperone o...

ProteomicsIdentification of PP1-fusion phosphatase substrates
This experiments was designed to identify substrates of holophosphatase complexes of PP1 and its specificity-determining regulator proteins. We generated fusions of Flag-tagged Protein Phosphatase 1 fusions with Phactr1-4, Neurabin, Spinophilin, PPPR15A, PPP1R15B, and PNUTS, in each case including k...

TranscriptomicsProtein phosphatase PP1-NIPP1 activates mesenchymal genes in HeLa cells
The deletion of the protein phosphatase-1 (PP1) regulator NIPP1 is embryonic lethal during gastrulation, hinting at a key role of PP1-NIPP1 in lineage specification. Consistent with this notion we show here that a mild, stable overexpression of NIPP1 in HeLa cells caused a massive in...

ProteomicsBasolateral Protein Scribble Provides Phosphatase PP1 to a Signaling Network Maintaining Apicobasal Polarity
Scribble, a member of the LAP protein family, contributes to the apicobasal polarity (ABP) of epithelial cells. The LAP unique region (LUR) of these proteins is essential for ABP function, and includes a highly conserved Leucine Reach Repeat (LRR) domain. Here we study how the LRR domain of Scribble...

ProteomicsPhactr1/PP1 phosphatase substrates in mouse NIH3T3 fibroblasts
It was previously shown that expression of an activated Phactr1 mutant (Phactr1XXX) that constitutively forms the Phactr1/PP1 phosphatase holoenzyme, induces F-actin rearrangements in NIH3T3 fibroblasts. Expression of the Phactr1 PP1-binding domain (C-terminal) alone is also sufficient to induce suc...

ProteomicsPP1/PNUTS phosphatase binds the restrictor complex and stimulates RNA pol II transcription termination
The restrictor, ZC3H4/WDR82, terminates antisense transcription from bidirectional promoters, but its mechanism is poorly understood. We report that ZC3H4/WDR82 immunoprecipitate with PP1 phosphatase and its nuclear targeting subunit, PNUTS, which binds to WDR82. AlphaFold predicts a complex of PP1/...

ProteomicsPhactr1/PP1 phosphatase substrates in mouse primary neurons
Neurons express Phactr1 at high level (Allen et al., 2004), and Phactr1 mutations are associated with morphological and functional developmental defects in cortical neurons (Hamada et al., 2018). To identify targets of the Phactr1/PP1 phosphatase holoenzyme, we cultured hippocampal and cortical neur...
