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

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