Structures of 9-1-1 DNA checkpoint clamp loading at gaps from start to finish and ramification on biology

Cell Reports, 2023
Summary: Rad24-RFC (replication factor C) loads the 9-1-1 checkpoint clamp onto the recessed 5′ ends by binding a 5′ DNA at an external surface site and threading the 3′ single-stranded DNA (ssDNA) into 9-1-1. We find here that Rad24-RFC loads 9-1-1 onto

An advanced cell cycle tag toolbox reveals principles underlying temporal control of structure-selective nucleases

eLife, 2020
Cell cycle tags allow to restrict target protein expression to specific cell cycle phases. Here, we present an advanced toolbox of cell cycle tag constructs in budding yeast with defined and compatible peak expression that allow comparison of protein ...

Proficient replication of the yeast genome by a viral DNA polymerase [PDF]

, 2016
DNA replication in eukaryotic cells requires minimally three B-family DNA polymerases: Pol α, Pol δ, and Pol ϵ. Pol δ replicates and matures Okazaki fragments on the lagging strand of the replication fork.

Reconstitution of a eukaryotic replisome reveals suppression mechanisms that define leading/lagging strand operation

eLife, 2015
We have reconstituted a eukaryotic leading/lagging strand replisome comprising 31 distinct polypeptides. This study identifies a process unprecedented in bacterial replisomes.

Influence of retinoblastoma-related gene silencing on the initiation of DNA replication by African cassava mosaic virus Rep in cells of mature leaves in Nicotiana benthamiana plants [PDF]

, 2011
Background Geminiviruses mainly infect terminally differentiated tissues and cells in plants. They need to reprogramme host cellular machinery for DNA replication.

Molecular choreography of primer synthesis by the eukaryotic Pol α-primase

Nature Communications, 2023
The eukaryotic polymerase α (Pol α) synthesizes an RNA-DNA hybrid primer of 20–30 nucleotides. Pol α is composed of Pol1, Pol12, Primase 1 (Pri1), and Pri2. Pol1 and Pri1 contain the DNA polymerase and RNA primase activities, respectively.

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

, 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 ...

Robust Replication Control Is Generated by Temporal Gaps between Licensing and Firing Phases and Depends on Degradation of Firing Factor Sld2

Cell Reports, 2016
Temporal separation of DNA replication initiation into licensing and firing phases ensures the precise duplication of the genome during each cell cycle.

DNA Replication Timing [PDF]

Cold Spring Harbor Perspectives in Biology, 2013
Patterns of replication within eukaryotic genomes correlate with gene expression, chromatin structure, and genome evolution. Recent advances in genome-scale mapping of replication kinetics have allowed these correlations to be explored in many species, cell types, and growth conditions, and these large data sets have allowed quantitative and ...

Implementing fluorescence enhancement, quenching, and FRET for investigating flap endonuclease 1 enzymatic reaction at the single-molecule level

Computational and Structural Biotechnology Journal, 2021
Flap endonuclease 1 (FEN1) is an important component of the intricate molecular machinery for DNA replication and repair. FEN1 is a structure-specific 5′ nuclease that cleaves nascent single-stranded 5′ flaps during the maturation of Okazaki fragments ...
