TranscriptomicsAvoiding chromosome pathology when replication forks collide
Chromosome duplication normally initiates via the assembly of replication fork complexes at defined origins. DNA synthesis by any one fork is thought to cease when it meets another travelling in the opposite direction, at which stage the replication machinery may simply dissociate before the nascent...

ProteomicsDynamics of de novo heterochromatin assembly and disassembly at replication forks ensures fork stability
Chromatin is dynamically reorganized when DNA replication forks are challenged. However, the process of epigenetic reorganization and its implication for fork stability is poorly understood. Here, we discover a checkpoint regulated cascade of chromatin signaling that activates 5 the histone methyl...

GenomicsGenome-wide analysis reveals that budding yeast Rif1 binds to replication origins and at blocked replication forks to protect nascent DNA
This experiment details ChIP sequencing to decipher the binding sites of the Rif1 protein in budding yeast. Rif1 binds most strongly to telomeres where its binding is mediated by Rap1. To reduce telomere binding and help reveal Rap1-independent binding sites, a truncation mutant of Rif1 lacking the ...

TranscriptomicsInvolvement of a chromatin remodeling complex in damage tolerance during DNA replication
ATP-dependent chromatin remodeling complexes have been shown to participate in DNA replication in addition to transcription and DNA repair. However, the mechanisms of their involvement in DNA replication remain unclear. Here, we reveal a specific function of the yeast INO80 chromatin remodeling comp...

TranscriptomicsGenome-wide localization of Ino80 on chromosome in Saccharomyces cerevisiae
Background: Chromatin remodeling complexes facilitate the access of enzymes that mediate transcription, replication or repair of DNA by modulating nucleosome position and/or composition. Ino80 is the DNA-dependent Snf2-like ATPase subunit of a complex whose nucleosome remodeling activity requires ac...

TranscriptomicsGenome-wide Profiling of DNA Replication Timing in pombe.
DNA replication is initiated at multiple sites or origins enriched with AT-rich sequences at various times during the S-phase. While current studies of genome-wide DNA replication profiles have focused on the timing of replication and the location of origins, the efficiency of replication/firing at...

TranscriptomicsTopoisomerase function in E. coli replication fork movement
Analysis of topoisomerase function in bacterial replication fork movement: use of DNA microarrays. We used DNA microarrays of the Escherichia coli genome to trace the progression of chromosomal replication forks in synchronized cells. We found that both DNA gyrase and topoisomerase IV (topo IV) prom...
