Translesion synthesis: Y-family polymerases and the polymerase switch

open access: yesDNA Repair, 2007
Replicative DNA polymerases are blocked at DNA lesions. Synthesis past DNA damage requires the replacement of the replicative polymerase by one of a group of specialised translesion synthesis (TLS) polymerases, most of which belong to the Y-family. Each of these has different substrate specificities for different types of damage.

The zinc finger domains of PARP‐1 are selectively and potently inhibited by the Au(I)‐based drugs sodium aurothiomalate and aurothioglucose

open access: yesFEBS Letters, EarlyView.
PARP‐1 is a key enzyme in the DNA damage response, and its inhibition induces cancer cell death via synthetic lethality. Au(I)‐based drugs, such as aurothioglucose and sodium aurothiomalate, block PARP‐1's DNA‐dependent activity by targeting its zinc finger domains.

eDNA Replicates, Polymerase and Amplicon Size Impact Inference of Richness Across Habitats

open access: yesEnvironmental DNA
Environmental DNA‐based monitoring has been increasingly used in the last decade to monitor biodiversity in aquatic and terrestrial systems. Molecular‐based surveys now allow quick and reliable production of baseline knowledge of species community ...

Characterization of the complete genome sequence of the recombinant norovirus GII.P16/GII.4_Sydney_2012 revealed in Russia

open access: yesВавиловский журнал генетики и селекции, 2020
Noroviruses (the Caliciviridae family) are a common cause of acute gastroenteritis in all age groups. These small non-envelope viruses with a single-stranded (+)RNA genome are characterized by high genetic variability.

DNA Polymerase ε: A Polymerase of Unusual Size (and Complexity) [PDF]

open access: yes, 2008
Publisher Summary DNA polymerase epsilon (Pol epsilon) is a large, multi-subunit polymerase that is conserved throughout all eukaryotes. In addition to its role as one of the three DNA polymerases responsible for bulk chromosomal replication, Pol epsilon is implicated in a wide variety of important cellular processes, including the repair of damaged ...

Interplay between circadian and other transcription factors—Implications for cycling transcriptome reprogramming

open access: yesFEBS Letters, EarlyView.
This perspective highlights emerging insights into how the circadian transcription factor CLOCK:BMAL1 regulates chromatin architecture, cooperates with other transcription factors, and coordinates enhancer dynamics. We propose an updated framework for how circadian transcription factors operate within dynamic and multifactorial chromatin landscapes ...

Influenza A Virus PA Antagonizes Interferon-β by Interacting with Interferon Regulatory Factor 3

open access: yesFrontiers in Immunology, 2017
The influenza A virus (IAV) can be recognized by retinoic acid-inducible gene I (RIG-I) to activate the type I interferon response and induce antiviral effects.

DNA Polymerase Profiling [PDF]

open access: yes, 2008
We report a simple homogeneous fluorescence assay for quantification of DNA polymerase function in high throughput. The fluorescence signal is generated by the DNA polymerase triggering opening of a molecular beacon extension of the template strand. A resulting distance alteration is reported by fluorescence resonance energy transfer between two dyes ...

Real‐time assay of ribonucleotide reductase activity with a fluorescent RNA aptamer

open access: yesFEBS Letters, EarlyView.
Ribonucleotide reductases (RNR) synthesize DNA building blocks de novo, making them crucial in DNA replication and drug targeting. FLARE introduces the first single‐tube real‐time coupled RNR assay, which enables isothermal tracking of RNR activity at nanomolar enzyme levels and allows the reconstruction of allosteric regulatory patterns and rapid ...
