Joint Efforts of Replicative Helicase and SSB Ensure Inherent Replicative Tolerance of G‐Quadruplex
G‐quadruplex (G4), a four‐stranded noncanonical DNA structure, has been recognized as a potent block to DNA replication. This study uncovers two G4‐overcoming replication pathways with the involvement of the core replisome only. Concisely, the replicative helicase coordinates with the SSB protein to unfold intramolecular G4 structures, paving the way ...

Cancer‐associated FBXW7 loss is synthetic lethal with pharmacological targeting of CDC7
Using the combination of whole genome CRISPR‐Cas9 screening, RNA interference screens, proteomic mass spectrometry profiling and small molecule inhibitors, Baxter et al. demonstrate that loss of FBXW7 in tumour cells imparts a synthetic lethal effect with CDC7 inhibition.

Faithful replication and repair of DNA lesions ensure genome maintenance. During replication in eukaryotic cells, DNA is unwound by the CMG helicase complex, which is composed of three major components: the Cdc45 protein, Mcm2-7, and the GINS complex ...

USP37 protects mammalian cells during DNA replication stress by counteracting CUL2LRR1 and TRAIP
Summary: The USP37 deubiquitylase is essential for mammalian cells to survive DNA replication stress, but the underlying mechanisms are unknown. Here, we demonstrate that USP37 binds the CDC45-MCM-GINS (CMG) helicase, which forms the stable core of the ...

Initiation-specific alleles of the Cdc45 helicase-activating protein.
The committed step in DNA replication initiation is the activation of the Mcm2-7 replicative DNA helicase. Two activators, Cdc45 and GINS, associate with Mcm2-7 at origins of replication to form the CMG complex, which is the active eukaryotic replicative

DNA replication requires recruitment of Cdc45 and GINS into the MCM double hexamer by initiation factors to form an active helicase, the Cdc45–MCM–GINS (CMG) complex, at the replication origins.

Hypomorphic GINS3 variants alter DNA replication and cause Meier-Gorlin syndrome
The eukaryotic CDC45/MCM2-7/GINS (CMG) helicase unwinds the DNA double helix during DNA replication. The GINS subcomplex is required for helicase activity and is, therefore, essential for DNA replication and cell viability.

USP37 prevents unscheduled replisome unloading through MCM complex deubiquitination
The CMG helicase (CDC45-MCM2-7-GINS) unwinds DNA as a component of eukaryotic replisomes. Replisome (dis)assembly is tightly coordinated with cell cycle progression to ensure genome stability.

Background In eukaryotes, the CMG (CDC45, MCM, GINS) complex containing the replicative helicase MCM is a key player in DNA replication. Archaeal homologs of the eukaryotic MCM and GINS proteins have been identified but until recently no homolog of the ...
