Control of DNA replication licensing in a cell cycle

H Nishitani, Z Lygerou - Genes to Cells, 2002 - Wiley Online Library
To maintain genome integrity in eukaryotes, DNA must be duplicated precisely once before
cell division occurs. A process called replication licensing ensures that chromosomes are …

Replication licensing aberrations, replication stress, and genomic instability

…, SC Tsaniras, S Taraviras, Z Lygerou - Trends in biochemical …, 2019 - cell.com
Strict regulation of DNA replication is of fundamental significance for the maintenance of
genome stability. Licensing of origins of DNA replication is a critical event for timely genome …

[HTML][HTML] Licensing of DNA replication, cancer, pluripotency and differentiation: an interlinked world?

…, IE Symeonidou, P Nikolopoulou, Z Lygerou… - Seminars in cell & …, 2014 - Elsevier
Recent findings provide evidence for a functional interplay between DNA replication and
the seemingly distinct areas of cancer, development and pluripotency. Protein complexes …

The Cdt1 protein is required to license DNA for replication in fission yeast

H Nishitani, Z Lygerou, T Nishimoto, P Nurse - Nature, 2000 - nature.com
To maintain genome stability in eukaryotic cells, DNA is licensed for replication only after the
cell has completed mitosis, ensuring that DNA synthesis (S phase) occurs once every cell …

Two E3 ubiquitin ligases, SCF‐Skp2 and DDB1‐Cul4, target human Cdt1 for proteolysis

…, KI Nakayama, K Nakayama, M Fujita, Z Lygerou… - The EMBO …, 2006 - embopress.org
Replication licensing is carefully regulated to restrict replication to once in a cell cycle. In
higher eukaryotes, regulation of the licensing factor Cdt1 by proteolysis and Geminin is …

[HTML][HTML] The human licensing factor for DNA replication Cdt1 accumulates in G1 and is destabilized after initiation of S-phase

H Nishitani, S Taraviras, Z Lygerou… - Journal of Biological …, 2001 - ASBMB
S-phase onset is controlled, so that it occurs only once every cell cycle. DNA is licensed for
replication after mitosis in G 1 , and passage through S-phase removes the license to …

Accurate processing of a eukaryotic precursor ribosomal RNA by ribonuclease MRP in vitro

Z Lygerou, C Allmang, D Tollervey, B Séraphin - Science, 1996 - science.org
Very few of the enzymes required for eukaryotic precursor ribosomal RNA (pre-rRNA)
processing have been identified. Ribonuclease (RNase) MRP was characterized as a nuclease …

Deregulated overexpression of hCdt1 and hCdc6 promotes malignant behavior

…, V Zoumpourlis, M Kouloukoussa, Z Lygerou… - Cancer research, 2007 - AACR
The accurate execution of DNA replication requires a strict control of the replication licensing
factors hCdt1 and hCdc6. The role of these key replication molecules in carcinogenesis …

easyFRAP: an interactive, easy-to-use tool for qualitative and quantitative analysis of FRAP data

…, NN Giakoumakis, S Taraviras, Z Lygerou - …, 2012 - academic.oup.com
We present easyFRAP, a versatile tool that assists quantitative and qualitative analysis of
fluorescence recovery after photobleaching (FRAP) data. The user can handle simultaneously …
