Genome duplication in Leishmania major relies on persistent subtelomeric DNA replication

eLife, 2020
DNA replication is needed to duplicate a cell’s genome in S phase and segregate it during cell division. Previous work in Leishmania detected DNA replication initiation at just a single region in each chromosome, an organisation predicted to be ...

Diversity of eukaryotic DNA replication origins revealed by genome-wide analysis of chromatin structure. [PDF]

PLoS Genetics, 2010
Eukaryotic DNA replication origins differ both in their efficiency and in the characteristic time during S phase when they become active. The biological basis for these differences remains unknown, but they could be a consequence of chromatin structure ...

Dynamic relocalization of replication origins by Fkh1 requires execution of DDK function and Cdc45 loading at origins

eLife, 2019
Chromosomal DNA elements are organized into spatial domains within the eukaryotic nucleus. Sites undergoing DNA replication, high-level transcription, and repair of double-strand breaks coalesce into foci, although the significance and mechanisms giving ...

Replication factory activation can be decoupled from the replication timing program by modulating Cdk levels [PDF]

, 2010
In the metazoan replication timing program, clusters of replication origins located in different subchromosomal domains fire at different times during S phase. We have used Xenopus laevis egg extracts to drive an accelerated replication timing program in

Ori-Finder 2022: A Comprehensive Web Server for Prediction and Analysis of Bacterial Replication Origins

Genomics, Proteomics & Bioinformatics, 2022
The replication of DNA is a complex biological process that is essential for life. Bacterial DNA replication is initiated at genomic loci referred to as replication origins (oriCs).

DNA replication licensing in somatic and germ cells [PDF]

, 2004
The DNA replication (or origin) licensing system ensures precise duplication of the genome in each cell cycle and is a powerful regulator of cell proliferation in metazoa.

Molecular Characterization of the Dbf4/Drf1-Dependent Kinase (DDK) and the DNA Replication Checkpoint Mediator Claspin in Xenopus Egg Extracts [PDF]

, 2010
The integrity of DNA replication control and checkpoint mechanisms is essential for preventing tumorigenesis. DNA replication is initiated by the S-CDK and DDK kinases which mediate the unwinding of the replication fork.

Identification of 1600 replication origins in S. cerevisiae

eLife
There are approximately 500 known origins of replication in the yeast genome, and the process by which DNA replication initiates at these locations is well understood.

Universal temporal profile of replication origin activation in eukaryotes. [PDF]

PLoS ONE, 2009
Although replication proteins are conserved among eukaryotes, the sequence requirements for replication initiation differ between species. In all species, however, replication origins fire asynchronously throughout S phase. The temporal program of origin

Molecular Architecture of the DNA Replication Origin Activation Checkpoint [PDF]

, 2010
Perturbation of DNA replication initiation arrests human cells in G1, pointing towards an origin activation checkpoint. We used RNAi against Cdc7 kinase to inhibit replication initiation and dissect this checkpoint in fibroblasts.
