Evidence for a role of Arabidopsis CDT1 proteins in gametophyte development and maintenance of genome integrity [PDF]

open access: yes, 2012
Meristems retain the ability to divide throughout the life cycle of plants, which can last for over 1000 years in some species. Furthermore, the germline is not laid down early during embryogenesis but originates from the meristematic cells relatively ...

A quantitative model of the initiation of DNA replication in Saccharomyces cerevisiae predicts the effects of system perturbations. [PDF]

open access: yes, 2012
BackgroundEukaryotic cell proliferation involves DNA replication, a tightly regulated process mediated by a multitude of protein factors. In budding yeast, the initiation of replication is facilitated by the heterohexameric origin recognition complex ...

Cryo-EM structure of a helicase loading intermediate containing ORC-Cdc6-Cdt1-MCM2-7 bound to DNA [PDF]

open access: yes, 2013
In eukaryotes, the Cdt1-bound replicative helicase core MCM2-7 is loaded onto DNA by the ORC-Cdc6 ATPase to form a prereplicative complex (pre-RC) with an MCM2-7 double hexamer encircling DNA.

Suppression of intrahepatic cholangiocarcinoma cell growth by SKI via upregulation of the CDK inhibitor p21

open access: yesFEBS Open Bio, 2022
Cholangiocarcinoma (CC) has a poor prognosis and different driver genes depending on the site of onset. Intrahepatic CC is the second‐most common liver cancer after hepatocellular carcinoma, and novel therapeutic targets are urgently needed.

Cdc6 ATPase activity disengages Cdc6 from the pre-replicative complex to promote DNA replication [PDF]

open access: yes, 2015
© 2015, Chang et al.To initiate DNA replication, cells first load an MCM helicase double hexamer at origins in a reaction requiring ORC, Cdc6, and Cdt1, also called pre-replicative complex (pre-RC) assembly.

A requirement for STAG2 in replication fork progression creates a targetable synthetic lethality in cohesin-mutant cancers. [PDF]

open access: yes, 2019
Cohesin is a multiprotein ring that is responsible for cohesion of sister chromatids and formation of DNA loops to regulate gene expression. Genomic analyses have identified that the cohesin subunit STAG2 is frequently inactivated by mutations in cancer.

In the absence of ATPase activity, pre-RC formation is blocked prior to MCM2-7 hexamer dimerization [PDF]

open access: yes, 2013
The origin recognition complex (ORC) of Saccharomyces cerevisiae binds origin DNA and cooperates with Cdc6 and Cdt1 to load the replicative helicase MCM2–7 onto DNA. Helicase loading involves two MCM2–7 hexamers that assemble into a double hexamer around

The Identification of Potential Therapeutic Targets for Cutaneous Squamous Cell Carcinoma [PDF]

open access: yes, 2020
We performed a small interfering RNA screen to identify targets for cutaneous squamous cell carcinoma (cSCC) therapy in the ubiquitin/ubiquitin-like system.

The dynamics of replication licensing in live Caenorhabditis elegans embryos [PDF]

open access: yes, 2012
Accurate DNA replication requires proper regulation of replication licensing, which entails loading MCM-2-7 onto replication origins. In this paper, we provide the first comprehensive view of replication licensing in vivo, using video microscopy of ...

Analysis of a temperature‐sensitive mutation in Uba1: Effects of the click reaction on subsequent immunolabeling of proteins involved in DNA replication

open access: yesFEBS Open Bio, 2015
In our previous study, a Met‐to‐Ile substitution at amino acid 256 in the catalytic domain of Uba1 was determined in temperature‐sensitive CHO‐K1 mutant tsTM3 cells, which exhibited chromosomal instability and cell‐cycle arrest in the S to G2 phases with
