Structural Insights into Eukaryotic DNA Replication [PDF]

open access: goldFrontiers 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.

Ancient diversification of eukaryotic MCM DNA replication proteins [PDF]

open access: goldBMC Evolutionary Biology, 2009
Background Yeast and animal cells require six mini-chromosome maintenance proteins (Mcm2-7) for pre-replication complex formation, DNA replication initiation and DNA synthesis. These six individual MCM proteins form distinct heterogeneous subunits within

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 ...

The major roles of DNA polymerases epsilon and delta at the eukaryotic replication fork are evolutionarily conserved.

open access: goldPLoS Genetics, 2011
Coordinated replication of eukaryotic genomes is intrinsically asymmetric, with continuous leading strand synthesis preceding discontinuous lagging strand synthesis.

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,
