Ciz1 cooperates with cyclin-A-CDK2 to activate mammalian DNA replication in vitro [PDF]

open access: yes, 2010
Initiation of mammalian DNA replication can be reconstituted from isolated G1-phase nuclei and cell extracts, supplemented with cyclin-dependent protein kinases (CDKs).

Depletion of Uhrf1 inhibits chromosomal DNA replication in Xenopus egg extracts [PDF]

open access: yes, 2013
UHRF1 (ubiquitin-like, containing PHD and RING finger domains 1) has a well-established role in epigenetic regulation through the recognition of various histone marks and interaction with chromatin-modifying proteins.

Methylation of histone H3 on lysine 79 associates with a group of replication origins and helps limit DNA replication once per cell cycle. [PDF]

open access: yesPLoS Genetics, 2013
Mammalian DNA replication starts at distinct chromosomal sites in a tissue-specific pattern coordinated with transcription, but previous studies have not yet identified a chromatin modification that correlates with the initiation of DNA replication at ...

Regulatory mechanisms that prevent re-initiation of DNA replication can be locally modulated at origins by nearby sequence elements. [PDF]

open access: yesPLoS Genetics, 2014
Eukaryotic cells must inhibit re-initiation of DNA replication at each of the thousands of origins in their genome because re-initiation can generate genomic alterations with extraordinary frequency.

A Dynamic Stochastic Model for DNA Replication Initiation in Early Embryos [PDF]

open access: yes, 2008
Background: Eukaryotic cells seem unable to monitor replication completion during normal S phase, yet must ensure a reliable replication completion time.

The Origin Recognition Complex: From Origin Selection to Replication Licensing in Yeast and Humans

open access: yesBiology, 2023
Understanding human DNA replication through the study of yeast has been an extremely fruitful journey. The minichromosome maintenance (MCM) 2–7 genes that encode the catalytic core of the eukaryotic replisome were initially identified through forward ...

Genome duplication in Leishmania major relies on persistent subtelomeric DNA replication

open access: yeseLife, 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 ...

The Stringent Response Inhibits DNA Replication Initiation in E. coli by Modulating Supercoiling of oriC

open access: yesmBio, 2019
The stringent response enables bacteria to respond to a variety of environmental stresses, especially various forms of nutrient limitation. During the stringent response, the cell produces large quantities of the nucleotide alarmone ppGpp, which ...

The Fis protein has a stimulating role in initiation of replication in Escherichia coli in vivo. [PDF]

open access: yesPLoS ONE, 2013
The Fis protein is a nucleoid associated protein that has previously been reported to act negatively in initiation of replication in Escherichia coli.

Genome-wide analysis reveals extensive functional interaction between DNA replication initiation and transcription in the genome of trypanosoma brucei [PDF]

open access: yes, 2012
Identification of replication initiation sites, termed origins, is a crucial step in understanding genome transmission in any organism. Transcription of the Trypanosoma brucei genome is highly unusual, with each chromosome comprising a few discrete ...
