ProteomicsPARP1 auto-modification promotes faithful Okazaki fragment processing and limits replication fork speed
Poly(ADP-ribose) polymerase (PARP) inhibitors have proven their efficacy for treating tumors defective in homologous recombination via synthetic lethality. In response to DNA breaks, PARP1 is the primary ADP-ribosylation writer, modifying itself (auto-modification) and other proteins to facilitate r...

OtherData for: Short-chain fatty acids activate acetyltransferase p300/CBP
The short-chain fatty acids (SCFAs) acetate, propionate, and butyrate are produced in large quantities by the gut microbiome and contribute to a wide array of physiological processes. While the underlying mechanisms are largely unknown, many effects of SCFAs have been traced to changes in epigenetic...

TranscriptomicsLOX-1 is an N6-methyladenosine-regulated receptor for Helicobacter pylori via binding to the bacterial catalase [RNA-seq]
The role of N6-methyladenosine (m6A) modification of host mRNA during bacterial infection is unclear. Here, we show that Helicobacter pylori infection upregulated major m6A “writers” and increased m6A level in gastric epithelial cells. Attenuating m6A increase by hemizygotic deletion of Mettl3 in mi...

TranscriptomicsMultigenerational Proteolytic Inactivation of Restriction Upon Subtle Genomic Hypomethylation in Pseudomonas aeruginosa
Restriction-modification (R-M) systems protect against phage infection by detecting and degrading invading foreign DNA. However, like many prokaryotic anti-phage defenses, R-M systems pose a significant risk of auto-immunity, exacerbated by the presence of hundreds to thousands of potential cleavage...

ProteomicsCullin-independent recognition of HHARI substrates by a dynamic RBR catalytic domain
RING-Between-RING (RBR) E3 ligases mediate ubiquitin transfer through an obligate E3- ubiquitin thioester intermediately prior to substrate ubiquitination. While RBRs share a conserved catalytic module, substrate recruitment mechanisms remain enigmatic and the relevant domains have yet to be identi...
