GINS maintains association of Cdc45 with MCM in replisome progression complexes at eukaryotic DNA replication forks

…, F Van Deursen, RD Edmondson, K Labib - Nature cell …, 2006 - nature.com
The components of the replisome that preserve genomic stability by controlling the progression
of eukaryotic DNA replication forks are poorly understood. Here, we show that the GINS (…

Uninterrupted MCM2-7 function required for DNA replication fork progression

K Labib, JA Tercero, JFX Diffley - Science, 2000 - science.org
Little is known about the DNA helicases required for the elongation phase of eukaryotic
chromosome replication. Minichromosome maintenance (MCM) protein complexes have DNA …

Chromosome Duplication in Saccharomyces cerevisiae

SP Bell, K Labib - Genetics, 2016 - academic.oup.com
The accurate and complete replication of genomic DNA is essential for all life. In eukaryotic
cells, the assembly of the multi-enzyme replisomes that perform replication is divided into …

[PDF][PDF] MINDY-1 is a member of an evolutionarily conserved and structurally distinct new family of deubiquitinating enzymes

…, SY Choi, PJ Nkosi, S Weidlich, K Labib… - Molecular cell, 2016 - cell.com
Deubiquitinating enzymes (DUBs) remove ubiquitin (Ub) from Ub-conjugated substrates to
regulate the functional outcome of ubiquitylation. Here we report the discovery of a new …

[PDF][PDF] Ctf4 is a hub in the eukaryotic replisome that links multiple CIP-box proteins to the CMG helicase

…, M Wightman, D Matak-Vinkovíc, L Pellegrini, K Labib - Molecular cell, 2016 - cell.com
Replisome assembly at eukaryotic replication forks connects the DNA helicase to DNA
polymerases and many other factors. The helicase binds the leading-strand polymerase directly, …

Cdc48 and a ubiquitin ligase drive disassembly of the CMG helicase at the end of DNA replication

M Maric, T Maculins, G De Piccoli, K Labib - Science, 2014 - science.org
Introduction Chromosome replication is initiated by a universal mechanism in eukaryotic
cells. This mechanism entails the assembly and activation at replication origins of the DNA …

How do Cdc7 and cyclin-dependent kinases trigger the initiation of chromosome replication in eukaryotic cells?

K Labib - Genes & development, 2010 - genesdev.cshlp.org
Chromosome replication occurs precisely once during the cell cycle of almost all eukaryotic
cells, and is a highly complex process that is still understood relatively poorly. Two …

MCM proteins: evolution, properties, and role in DNA replication

SE Kearsey, K Labib - Biochimica et Biophysica Acta (BBA)-Gene Structure …, 1998 - Elsevier
The replication of DNA is a fundamental step in the cell cycle, which must be coordinated
with cell division to ensure that the daughter cells have the same ploidy as the parental cell. …

Molecular anatomy and regulation of a stable replisome at a paused eukaryotic DNA replication fork

…, M Kanemaki, A Bueno, K Labib - Genes & …, 2005 - genesdev.cshlp.org
Eukaryotic cells regulate the progression and integrity of DNA replication forks to maintain
genomic stability and couple DNA synthesis to other processes. The budding yeast proteins …

A key role for Ctf4 in coupling the MCM2‐7 helicase to DNA polymerase α within the eukaryotic replisome

…, RC Jones, RD Edmondson, A Calzada, K Labib - The EMBO …, 2009 - embopress.org
The eukaryotic replisome is a crucial determinant of genome stability, but its structure is still
poorly understood. We found previously that many regulatory proteins assemble around the …
