Damage-induced phosphorylation of Sld3 is important to block late origin firing. [PDF]

open access: yes, 2010
Origins of replication are activated throughout the S phase of the cell cycle such that some origins fire early and others fire late to ensure that each chromosome is completely replicated in a timely fashion.

Chromatin Controls DNA Replication Origin Selection, Lagging-Strand Synthesis, and Replication Fork Rates

open access: yesMolecules and Cells, 2017
Summary The integrity of eukaryotic genomes requires rapid and regulated chromatin replication. How this is accomplished is still poorly understood. Using purified yeast replication proteins and fully chromatinized templates, we have reconstituted this ...

The origin of replicators and reproducers [PDF]

open access: yesPhilosophical Transactions of the Royal Society B: Biological Sciences, 2006
Replicators are fundamental to the origin of life and evolvability. Their survival depends on the accuracy of replication and the efficiency of growth relative to spontaneous decay. Infrabiological systems are built of two coupled autocatalytic systems, in contrast to minimal living systems that must comprise at least a metabolic subsystem, a ...

Mechanism of DNA Recognition at a Viral Replication Origin [PDF]

open access: yes, 2006
Recognition of the DNA origin by the Epstein-Barr nuclear antigen 1 (EBNA1) protein is the primary event in latentphase genome replication of the Epstein-Barr virus, a model for replication initiation in eukaryotes.

The level of origin firing inversely affects the rate of replication fork progression

open access: yesJournal of Cell Biology, 2013
Cells with reduced origin firing have an increased rate of replication fork progression, whereas fork progression is slowed in cells with excess origins.

Concurrent Replication and Methylation at Mammalian Origins of Replication [PDF]

open access: yesMolecular and Cellular Biology, 1998
Observations made with Escherichia coli have suggested that a lag between replication and methylation regulates initiation of replication. To address the question of whether a similar mechanism operates in mammalian cells, we have determined the temporal relationship between initiation of replication and methylation in mammalian cells both at a ...

Identification of a Novel 81-kDa Component of the Xenopus Origin Recognition Complex [PDF]

open access: yes, 1998
The Xenopus origin recognition complex is essential for chromosomal DNA replication in cell-free extracts. We have immunopurified the Xenopus origin recognition complex with anti-Xorc2 antibodies and analyzed its composition and properties.

Replication control: Choreographing replication origins [PDF]

open access: yesCurrent Biology, 1998
Budding yeast replication origins are activated during S phase according to a predetermined temporal programme. Two recent studies indicate that this programme is executed, at least in part, by the S-phase-promoting cyclins that act to assemble a pre-initiation complex which includes the Cdc45 protein.

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

open access: yesPLoS 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

Human RIF1 and protein phosphatase 1 stimulate DNA replication origin licensing but suppress origin activation

open access: yesEMBO Reports, 2017
The human RIF1 protein controls DNA replication, but the molecular mechanism is largely unknown. Here, we demonstrate that human RIF1 negatively regulates DNA replication by forming a complex with protein phosphatase 1 (PP1) that limits phosphorylation ...
