Summary from GEO: "During genome replication, the leading strand DNA polymerase conducts continuous synthesis over long stretches of DNA within each replicon. Processive DNA synthesis supports symmetric progression of sister replication forks and efficient genome duplication. To address the mechanisms underlying leading strand polymerase-mediated synthesis, we examine one of its conserved domains,...

Summary from GEO: "Replicon-seq is a method to study the progression of sister replisomes during DNA replication. This method relies excision of the full-length of replicons by the fusion of MNase to MCM4 and sequencing via Nanopore technology." Overall design from GEO: "MCM4 was fused to Miccrococcal nuclease ( MNase) to generate DNA double strand break at the site of replisomes. DNA ends are...

Summary from GEO: "Oncogenic mutations in the metabolic enzyme isocitrate dehydrogenase 1 and 2 (IDH1/2) have been found in a number of liquid and solid tumors. Their pathogenic mechanism of action involves production of 2-hydroxyglutarate (2HG), an oncometabolite that acts in part by inhibiting members of a family of dioxygenases that modulate chromatin dynamics. Recent work has suggested that mutant...

Description from PRIDE: "The pathways involved in suppressing DNA replication stress and the associated DNA damage are critical to maintaining genome integrity. The Mre11 complex is unique among double strand break (DSB) repair proteins for its association with the DNA replication fork. Here we show that Mre11 complex inactivation causes DNA replication stress and changes in the abundance of proteins...

To date few DDK substrates other than the MCM helicase have been identified, and none are implicated in fork protection or restart. Here we searched for such factors, using SILAC and quantitative mass spectrometry to identify the DDK phosphoproteome during fork stalling.

Sumoylation is emerging as a post-translation modification important for chromosome duplication and stability. The origin recognition complex (ORC), which directs DNA replication initiation by loading the MCM replicative helicases onto origins, is sumoylated in both yeast and human cells. However, the biological consequences of ORC sumoylation are largely unclear. Here we report the effects of hyper-...

Summary from GEO: "We show that ligation-competent Okazaki fragments in Saccharomyces cerevisiae are sized according to the chromatin repeat. Using deep sequencing, we demonstrate that ligation junctions preferentially occur around nucleosome midpoints rather than in internucleosomal linker regions. Disrupting chromatin assembly or lagging strand polymerase processivity impacts both the size and...

Summary from GEO: "We have previously shown that Okazaki fragments in Saccharomyces cerevisiae are sized according to the chromatin repeat. Here we demonstrate that nucleosome positioning is rapidly established on newly synthesized DNA. Using deep sequencing, we demonstrate that ATP-dependent chromatin remodeling enzymes, Isw1 and Chd1, collaborate with histone chaperones, such as CAF-1 and Rtt106,...
