The Initiation of Eukaryotic DNA Replication.

open access: yesAnnual Review of Biochemistry, 2022
DNA replication in eukaryotic cells initiates from large numbers of sites called replication origins. Initiation of replication from these origins must be tightly controlled to ensure the entire genome is precisely duplicated in each cell cycle.

Cyclin E/CDK2: DNA Replication, Replication Stress and Genomic Instability

open access: yesFrontiers in Cell and Developmental Biology, 2021
DNA replication must be precisely controlled in order to maintain genome stability. Transition through cell cycle phases is regulated by a family of Cyclin-Dependent Kinases (CDKs) in association with respective cyclin regulatory subunits. In normal cell

MTBP phosphorylation controls DNA replication origin firing

open access: yesScientific Reports, 2021
Faithful genome duplication requires regulation of origin firing to determine loci, timing and efficiency of replisome generation. Established kinase targets for eukaryotic origin firing regulation are the Mcm2-7 helicase, Sld3/Treslin/TICRR and Sld2 ...

The structural basis of Cdc7-Dbf4 kinase dependent targeting and phosphorylation of the MCM2-7 double hexamer

open access: yesNature Communications, 2022
Here the authors describe multiple structures of the replicative helicase MCM2-7 in complex with Dbf4-dependent kinase (DDK). These structures reveal why the kinase specifically recognizes the MCM2-7 double-hexamer over the single-hexamer and explain how

The Contribution of Lysosomes to DNA Replication

open access: yesCells, 2021
Lysosomes, acidic, membrane-bound organelles, are not only the core of the cellular recycling machinery, but they also serve as signaling hubs regulating various metabolic pathways. Lysosomes maintain energy homeostasis and provide pivotal substrates for

Cryo-EM structures reveal that RFC recognizes both the 3′- and 5′-DNA ends to load PCNA onto gaps for DNA repair

open access: yeseLife, 2022
RFC uses ATP to assemble PCNA onto primed sites for replicative DNA polymerases δ and ε. The RFC pentamer forms a central chamber that binds 3′ ss/ds DNA junctions to load PCNA onto DNA during replication.

Adenovirus DNA Replication [PDF]

open access: yesCold Spring Harbor Perspectives in Biology, 2013
Adenoviruses have attracted much attention as probes to study biological processes such as DNA replication, transcription, splicing, and cellular transformation. More recently these viruses have been used as gene-transfer vectors and oncolytic agents.

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 ...
