Polymerase dynamics at the eukaryotic DNA replication fork.
This review discusses recent insights in the roles of DNA polymerases (Pol) delta and epsilon in eukaryotic DNA replication. A growing body of evidence specifies Pol epsilon as the leading strand DNA polymerase and Pol delta as the lagging strand polymerase during undisturbed DNA replication. New evidence supporting this model comes from the use of polymerase mutants that show an asymmetric mut...
متن کاملPin1 interacts with the Epstein-Barr virus DNA polymerase catalytic subunit and regulates viral DNA replication.
Peptidyl-prolyl cis-trans isomerase NIMA-interacting 1 (Pin1) protein is known as a regulator which recognizes phosphorylated Ser/Thr-Pro motifs and increases the rate of cis and trans amide isomer interconversion, thereby altering the conformation of its substrates. We found that Pin1 knockdown using short hairpin RNA (shRNA) technology resulted in strong suppression of productive Epstein-Barr...
متن کاملThe DNA replication fork in eukaryotic cells.
Replication of the two template strands at eukaryotic cell DNA replication forks is a highly coordinated process that ensures accurate and efficient genome duplication. Biochemical studies, principally of plasmid DNAs containing the Simian Virus 40 origin of DNA replication, and yeast genetic studies have uncovered the fundamental mechanisms of replication fork progression. At least two differe...
متن کاملDNA polymerases that propagate the eukaryotic DNA replication fork.
Three DNA polymerases are thought to function at the eukaryotic DNA replication fork. Currently, a coherent model has been derived for the composition and activities of the lagging strand machinery. RNA-DNA primers are initiated by DNA polymerase ot-primase. Loading of the proliferating cell nuclear antigen, PCNA, dissociates DNA polymerase ca and recruits DNA polymerase S and the flap endonucl...
متن کاملHERC2 Interacts with Claspin and regulates DNA origin firing and replication fork progression.
DNA replication, recombination, and repair are highly interconnected processes the disruption of which must be coordinated in cancer. HERC2, a large HECT protein required for homologous recombination repair, is an E3 ubiquitin ligase that targets breast cancer suppressor BRCA1 for degradation. Here, we show that HERC2 is a component of the DNA replication fork complex that plays a critical role...
