ABSTRACT Deoxyuridine (dUrd) is often misincorporated into genomic DNA in cancer patients receiving antimetabolite chemotherapy. This activates base excision repair and recruits ataxia telangiectasia‐mutated and Rad3‐related (ATR), which coordinates DNA repair with nucleotide metabolism by facilitating ribonucleotide reductase (RNR) activity ...

Thermostable DNA polymerases, such as Taq isolated from the thermophilic bacterium Thermus aquaticus, enable one-pot exponential DNA amplification known as polymerase chain reaction (PCR). However, properties other than thermostability - such as fidelity,

Receptors responsive to extracellular pyrimidine nucleotides.
Extracellular adenine nucleotides have long been known to mediate pharmacological responses via several subtypes of P2 purinoceptors. More recently, however, similar responses to uracil nucleotides have been demonstrated.

Abstract Deoxyuridine triphosphatase (dUTPase) is essential for DNA replication fidelity and embryonic development in metazoa, yet whether a protein inhibitor can acutely disrupt dUTPase function in a living vertebrate has not been tested. The Staphylococcus aureus Stl protein inhibits diverse dUTPases in vitro, but its efficacy in a eukaryotic ...

ABSTRACT DNA library construction methods can affect the recovery of ancient DNA, thus influencing downstream analyses. While single‐stranded library preparation (ssLib) has been shown to outperform double‐stranded (dsLib) for highly degraded vertebrate host DNA, especially for samples older than 40,000 years, few studies have examined how library ...

YIPFα1A expression is regulated by multilayered molecular mechanisms
YIPFα1A, a five‐pass Golgi protein, is regulated at multiple layers. (1) Rare‐codon enrichment drives translation‐coupled mRNA decay. (2) A proximal 3′‐UTR element stabilizes mRNA. (3) A distal 3′‐UTR element included by alternate poly(A) site usage represses translation, which can be overridden by the proximal 3′‐UTR element.

Ribosylurea accumulates in yeast urc4 mutants.
Yeast Saccharomyces (Lachancea) kluyveri urc4 mutants, unable to grow on uracil, biotransformed (14)C(2)-uracil into two labeled compounds, as detected by high performance liquid chromatography (HPLC). These two compounds could also be obtained following

Current genome‐reduction methods work in a trial‐and‐error fashion, constituting a long‐standing bottleneck in the research. We developed CREAT (CRISPR‐based genome trimming with a multi‐homology‐arm template), a CRISPR‐based genetic approach that enables systematically classifying essential versus non‐essential genomic regions and subsequently ...

Synergistic HMGN1 and VP64 Fusions Potentiate High‐Precision and PAM‐Flexible Base Editing
A novel CDA1Δ‐SpRY architecture fused with HMGN1 and VP64 yields a nearly PAM‐less base editing platform. By focusing cytosine conversion predominantly at position −18, this synergistic complex ensures highly precise targeting. Demonstrating enhanced efficiency across diverse models, including yeast and rice, the platform offers a robust solution for ...
