Intragenic origins due to short G1 phases underlie oncogene-induced DNA replication stress
Nature, 2018 Oncogene-induced DNA replication stress contributes critically to the genomic instability that is present in cancer. However, elucidating how oncogenes deregulate DNA replication has been impeded by difficulty in mapping replication initiation sites on ...

Replicative DNA Polymerases [PDF]
Cold Spring Harbor Perspectives in Biology, 2013 In 1959, Arthur Kornberg was awarded the Nobel Prize for his work on the principles by which DNA is duplicated by DNA polymerases. Since then, it has been confirmed in all branches of life that replicative DNA polymerases require a single-stranded template to build a complementary strand, but they cannot start a new DNA strand de novo.

Nucleosome-directed replication origin licensing independent of a consensus DNA sequence
Nature Communications, 2022 Most eukaryotes do not use a consensus DNA sequence as binding sites for the origin recognition complex (ORC) to initiate DNA replication, however budding yeast do. Here the authors show S. cerevisiae ORC can bind nucleosomes near nucleosome-free regions

DNA Replication Fidelity [PDF]
Journal of Biological Chemistry, 1992 ▪ Abstract DNA replication fidelity is a key determinant of genome stability and is central to the evolution of species and to the origins of human diseases. Here we review our current understanding of replication fidelity, with emphasis on structural and biochemical studies of DNA polymerases that provide new insights into the importance of hydrogen ...

Cold Spring Harbor Perspectives in Biology, 2013 The onset of genomic DNA synthesis requires precise interactions of specialized initiator proteins with DNA at sites where the replication machinery can be loaded. These sites, defined as replication origins, are found at a few unique locations in all of the prokaryotic chromosomes examined so far.

Exploiting DNA Replication Stress for Cancer Treatment.
Cancer Research, 2019 Complete and accurate DNA replication is fundamental to cellular proliferation and genome stability. Obstacles that delay, prevent, or terminate DNA replication cause the phenomena termed DNA replication stress.

Quantitative sensing and signalling of single-stranded DNA during the DNA damage response
Nature Communications, 2019 DNA damage triggers checkpoint signalling mechanisms. Here the authors reveal differential phosphorylation of targets of the Mec1-Ddc2 checkpoint kinase by analyzing the effect of quantitatively different ssDNA signals.

MCM2 promotes symmetric inheritance of modified histones during DNA replication
Science, 2018 How cells ensure symmetric inheritance Parental histones with modifications are recycled to newly replicated DNA strands during genome replication, but do the two sister chromatids inherit modified histones equally? Yu et al. and Petryk et al.

eLife, 2017 DNA double strand breaks (DSBs) can be repaired by either recombination-based or direct ligation-based mechanisms. Pathway choice is made at the level of DNA end resection, a nucleolytic processing step, which primes DSBs for repair by recombination ...
