Origin licensing requires ATP binding and hydrolysis by the MCM replicative helicase.
(CELL PRESS, 2014-09-04)
Loading of the six related Minichromosome Maintenance (MCM) proteins as head-to-head double hexamers during DNA replication origin licensing is crucial for ensuring once-per-cell-cycle DNA replication in eukaryotic cells. ...
EXD2 Protects Stressed Replication Forks and Is Required for Cell Viability in the Absence of BRCA1/2.
(CELL PRESS, 2019-08-08)
Accurate DNA replication is essential to preserve genomic integrity and prevent chromosomal instability-associated diseases including cancer. Key to this process is the cells' ability to stabilize and restart stalled ...
Budding yeast Rap1, but not telomeric DNA, is inhibitory for multiple stages of DNA replication in vitro.
(OXFORD UNIV PRESS, 2021-06-04)
Telomeres are copied and reassembled each cell division cycle through a multistep process called telomere replication. Most telomeric DNA is duplicated semiconservatively during this process, but replication forks frequently ...
Pathway choice in the alternative telomere lengthening in neoplasia is dictated by replication fork processing mediated by EXD2's nuclease activity.
(NATURE PORTFOLIO, 2023-04-27)
Telomerase-independent cancer proliferation via the alternative lengthening of telomeres (ALT) relies upon two distinct, largely uncharacterized, break-induced-replication (BIR) processes. How cancer cells initiate and ...
Bidirectional eukaryotic DNA replication is established by quasi-symmetrical helicase loading.
(AMER ASSOC ADVANCEMENT SCIENCE, 2017-07-21)
Bidirectional replication from eukaryotic DNA replication origins requires the loading of two ring-shaped minichromosome maintenance (MCM) helicases around DNA in opposite orientations. MCM loading is orchestrated by binding ...
WASp modulates RPA function on single-stranded DNA in response to replication stress and DNA damage.
(NATURE PORTFOLIO, 2022-06-29)
Perturbation in the replication-stress response (RSR) and DNA-damage response (DDR) causes genomic instability. Genomic instability occurs in Wiskott-Aldrich syndrome (WAS), a primary immunodeficiency disorder, yet the ...
The mechanism of replication stalling and recovery within repetitive DNA.
(NATURE PORTFOLIO, 2022-07-19)
Accurate chromosomal DNA replication is essential to maintain genomic stability. Genetic evidence suggests that certain repetitive sequences impair replication, yet the underlying mechanism is poorly defined. Replication ...
Actin nucleators safeguard replication forks by limiting nascent strand degradation.
(OXFORD UNIV PRESS, 2023-07-07)
Accurate genome replication is essential for all life and a key mechanism of disease prevention, underpinned by the ability of cells to respond to replicative stress (RS) and protect replication forks. These responses rely ...
