Chromosome-wide histone deacetylation by sirtuins prevents hyperactivation of DNA damage-induced signaling upon replicative stress.
Wurtele et al., Montréal, Canada. In Nucleic Acids Res, Feb 2016
Our results further reveal that in the presence of constitutive H3K56ac, the Slx4 scaffolding protein and PP4 phosphatase complex play essential roles in preventing hyperactivation of the DNA damage-response kinase Rad53 in response to spontaneous DNA damage caused by reactive oxygen species.

Yang et al., Hangzhou, China. In Development, Feb 2016
On the basis of these results, a two-step process for the basal localization of Mira during NB division is revealed: cortical association of Mira mediated by the PTPA-PP4 complex is followed by apical aPKC-mediated basal restriction.
Inhibition of hippocampal plasticity in rats performing contrafreeloading for water under repeated administrations of pramipexole.

Jun et al., Hangzhou, China. In Gynecol Endocrinol, Nov 2015
We studied cell proliferation with 3-(4,5-dimethylthiazol-2-yl)2,5-diphenyl tetrazolium bromide, and, mitotic activity with phosphohistone H3 (PPH3) expression in leiomyoma, and, matched, normal, smooth muscle tissues using standard immunohistochemistry. Downregulation of GPER-1 expression with siGPR30 partially attenuated the E2-activated MAPK signaling pathway (p < 0.01).

Tulio de Mello et al., São Paulo, Brazil. In Sleep Sci, 2014
The rats were divided into control (CTRL) and drug (Pramipexole-PPX) groups that received daily saline vehicle and PPX treatments, respectively, for 71 days.
Protein phosphatases PP2A, PP4 and PP6: mediators and regulators in development and responses to environmental cues.
Jonassen et al., Stavanger, Norway. In Plant Cell Environ, 2014
The three closely related groups of serine/threonine protein phosphatases PP2A, PP4 and PP6 are conserved throughout eukaryotes.
TIPRL Inhibits Protein Phosphatase 4 Activity and Promotes H2AX Phosphorylation in the DNA Damage Response.
Kong et al., Duarte, United States. In Plos One, 2014
Here we show that Tip41-like protein (TIPRL), an evolutionarily conserved binding protein for PP2A-family phosphatases, is a negative regulator of protein phosphatase 4 (PP4).
Protein phosphatase 4 (PP4) functions as a critical regulator in tumor necrosis factor (TNF)-α-induced hepatic insulin resistance.
Li et al., Beijing, China. In Sci Rep, 2014
Protein phosphatase 4 (PP4) was shown to participate in multiple cellular processes, including DNA damage response, cell cycle and embryo development.
Replication stress is a potent driver of functional decline in ageing haematopoietic stem cells.
Passegué et al., San Francisco, United States. In Nature, 2014
Moreover, once old HSCs re-establish quiescence, residual replication stress on ribosomal DNA (rDNA) genes leads to the formation of nucleolar-associated γH2AX signals, which persist owing to ineffective H2AX dephosphorylation by mislocalized PP4c phosphatase rather than ongoing DNA damage.
The taming of the NF-κB: PP4R1 navigates while PP4c dephosphorylates.
Aifantis et al., New York City, United States. In Immunity, 2012

A PP4 holoenzyme balances physiological and oncogenic nuclear factor-kappa B signaling in T lymphocytes.
Arnold et al., Heidelberg, Germany. In Immunity, 2012
PP4R1 formed part of a distinct PP4 holoenzyme and bridged the inhibitor of NF-κB kinase (IKK) complex and the phosphatase PP4c, thereby directing PP4c activity to dephosphorylate and inactivate the IKK complex.
Phosphoproteomic analysis reveals that PP4 dephosphorylates KAP-1 impacting the DNA damage response.
Chowdhury et al., Boston, United States. In Embo J, 2012
The authors devised a novel proteomic strategy for systematic identification of proteins dephosphorylated by PP4C and identified KRAB-domain-associated protein 1 (KAP-1) as a substrate.
