The role of MCM proteins in the cell cycle control of genome duplicationS E Kearsey
Department of Zoology, University of Oxford, England
Bioessays 18:183-90. 1996..This review will discuss in particular the role of proteins in the minichromosome maintenance (MCM) family, which may hold the key to understanding how DNA is replicated once, and only once, per cell cycle...
Chromatin binding of the fission yeast replication factor mcm4 occurs during anaphase and requires ORC and cdc18S E Kearsey

GINS inactivation phenotypes reveal two pathways for chromatin association of replicative alpha and epsilon DNA polymerases in fission yeastChen Chun Pai
Department of Zoology, University of Oxford, Oxford OX1 3PS, United Kingdom
Mol Biol Cell 20:1213-22. 2009..We suggest that GINS functions in a pathway that involves Cdc45 and is necessary for DNA polymerase epsilon chromatin binding, but that a separate pathway sets up the chromatin association of DNA polymerase alpha...

Conditional inactivation of replication proteins in fission yeast using hormone-binding domainsChen Chun Pai
Department of Zoology, University of Oxford, Oxford, UK
Methods 57:227-33. 2012..In this article, we describe the application of this method in fission yeast, specifically with regard to analysis of the function of GINS, an essential component of the eukaryotic replicative helicase, the CMG complex...
Analysis of Mcm2-7 chromatin binding during anaphase and in the transition to quiescence in fission yeastMandana Namdar
Department of Zoology, University of Oxford, South Parks Road, Oxford, OX1 3PS, UK
Exp Cell Res 312:3360-9. 2006..We also examined Mcm2-7 chromatin association when cells enter a G0-like quiescent state. Chromatin binding is lost in this transition in a process that does not require DNA replication or the selective degradation of specific subunits...
Nuclear distribution and chromatin association of DNA polymerase alpha-primase is affected by TEV protease cleavage of Cdc23 (Mcm10) in fission yeastXiaowen Yang
Department of Zoology, University of Oxford, South Parks Road, Oxford OX13PS, UK
BMC Mol Biol 6:13. 2005..Cdc23/Mcm10 is required for the initiation and elongation steps of DNA replication but its biochemical function is unclear. Here, we probe its function using a novel approach in fission yeast, involving Cdc23 cleavage by the TEV protease...
Break-induced ATR and Ddb1-Cul4(Cdt)² ubiquitin ligase-dependent nucleotide synthesis promotes homologous recombination repair in fission yeastJennifer Moss
Department of Oncology, Cancer Research UK Medical Research Council Gray Institute for Radiation Oncology and Biology, University of Oxford, United Kingdom
Genes Dev 24:2705-16. 2010..Our findings support a model in which break-induced Rad3 and Ddb1-Cul4(Cdt)² ubiquitin ligase-dependent Spd1 degradation and RNR activation promotes postsynaptic ssDNA gap filling during HR repair...
