The capacity of origins to load MCM establishes replication timing patterns

L Dukaj, N Rhind - PLoS Genetics, 2021 - journals.plos.org
Loading of the MCM replicative helicase at origins of replication is a highly regulated
process that precedes DNA replication in all eukaryotes. The stoichiometry of MCM loaded …

Human ORC/MCM density is low in active genes and correlates with replication time but does not delimit initiation zones

N Kirstein, A Buschle, X Wu, S Krebs, H Blum… - Elife, 2021 - elifesciences.org
Eukaryotic DNA replication initiates during S phase from origins that have been licensed in
the preceding G1 phase. Here, we compare ChIP-seq profiles of the licensing factors Orc2 …

Methylation of histone H3 at lysine 37 by Set1 and Set2 prevents spurious DNA replication

H Santos-Rosa, G Millan-Zambrano, N Han, T Leonardi… - Molecular cell, 2021 - cell.com

driven both by the uneven loading of pre-replication complexes (pre-RCs) across the …

Chromatin structure restricts origin utilization when quiescent cells re-enter the cell cycle

PH Lee, MA Osley - Nucleic Acids Research, 2021 - academic.oup.com
Quiescent cells reside in G0 phase, which is characterized by the absence of cell growth
and proliferation. These cells remain viable and re-enter the cell cycle when prompted by …
