Structural Insights into Eukaryotic DNA Replication [PDF]

open access: yesFrontiers in Microbiology, 2014
Three DNA polymerases of the B family function at the replication fork in eukaryotic cells: DNA polymerases α, δ, and ε. DNA polymerase α, an heterotetramer composed of two primase subunits and two polymerase subunits, initiates replication.

Eukaryotic DNA Replication Fork. [PDF]

open access: yesAnnu Rev Biochem, 2017
This review focuses on the biogenesis and composition of the eukaryotic DNA replication fork, with an emphasis on the enzymes that synthesize DNA and repair discontinuities on the lagging strand of the replication fork. Physical and genetic methodologies aimed at understanding these processes are discussed.

Archaeology of eukaryotic DNA replication. [PDF]

open access: yesCold Spring Harb Perspect Biol, 2013
Recent advances in the characterization of the archaeal DNA replication system together with comparative genomic analysis have led to the identification of several previously uncharacterized archaeal proteins involved in replication and currently reveal a nearly complete correspondence between the components of the archaeal and eukaryotic replication ...

Emerging players in the initiation of eukaryotic DNA replication [PDF]

open access: yesCell Division, 2012
Faithful duplication of the genome in eukaryotes requires ordered assembly of a multi-protein complex called the pre-replicative complex (pre-RC) prior to S phase; transition to the pre-initiation complex (pre-IC) at the beginning of DNA replication ...

Nucleosome-directed replication origin licensing independent of a consensus DNA sequence

open access: yesNature 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

Accurate Identification of DNA Replication Origin by Fusing Epigenomics and Chromatin Interaction Information

open access: yesResearch, 2022
DNA replication initiation is a complex process involving various genetic and epigenomic signatures. The correct identification of replication origins (ORIs) could provide important clues for the study of a variety of diseases caused by replication. Here,

The structure of ORC–Cdc6 on an origin DNA reveals the mechanism of ORC activation by the replication initiator Cdc6

open access: yesNature Communications, 2021
Eukaryotic DNA replication is mediated by many proteins which are tightly regulated for an efficient firing of replication at each cell cycle. Here the authors report a cryo-EM structure of the yeast ORC–Cdc6 bound to an 85-bp ARS1 origin DNA revealing ...

The organizer of chromatin topology RIF1 ensures cellular resilience to DNA replication stress

open access: yesLife Science Alliance, 2023
The conserved protein RIF1 stabilizes replication factories and regulates cohesin recruitment in response to replication stress to limit DNA lesions. Eukaryotic genomes are duplicated from thousands of replication origins that fire sequentially forming a

An Essential and Cell-Cycle-Dependent ORC Dimerization Cycle Regulates Eukaryotic Chromosomal DNA Replication

open access: yesCell Reports, 2020
Summary: Eukaryotic DNA replication licensing is a prerequisite for, and plays a role in, regulating genome duplication that occurs exactly once per cell cycle.

Quantification of DNA-associated proteins inside eukaryotic cells using single-molecule localization microscopy [PDF]

open access: yes, 2014
Development of single-molecule localization microscopy techniques has allowed nanometre scale localization accuracy inside cells, permitting the resolution of ultra-fine cell structure and the elucidation of crucial molecular mechanisms.
