FEBS Letters, EarlyView.We identified a systemic, progressive loss of protein S‐glutathionylation—detected by nonreducing western blotting—alongside dysregulation of glutathione‐cycle enzymes in both neuronal and peripheral tissues of Taiwanese SMA mice. These alterations were partially rescued by SMN antisense oligonucleotide therapy, revealing persistent redox imbalance as ...

The Temporal Order of DNA Replication Shaped by Mammalian DNA Methyltransferases
Cells, 2021 Multiple epigenetic pathways underlie the temporal order of DNA replication (replication timing) in the contexts of development and disease. DNA methylation by DNA methyltransferases (Dnmts) and downstream chromatin reorganization and transcriptional ...

A requirement for STAG2 in replication fork progression creates a targetable synthetic lethality in cohesin-mutant cancers. [PDF]
, 2019 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.

Journal of Biological Chemistry, 1983 In this review, we will summarize new approaches to the study of DNA replication in yeast made possible by recombinant DNA technology, and in particular, survey results obtained with in vitro replication systems. Other recent reviews that summarize previous yeast replication studies are those of Fangman and Zakian and Petes.

Replication of baculovirus DNA
Journal of General Virology, 1995 Introduction. The Baculoviridae is a diverse family of pathogens that are infectious for arthropods and are characterized by a complex replication cycle that culminates in the occlusion of virions in a crystalline protein matrix (Blissard & Rohrmann, 1990).

Annual Review of Microbiology, 2020 It is now well recognized that the information processing machineries of archaea are far more closely related to those of eukaryotes than to those of their prokaryotic cousins, the bacteria. Extensive studies have been performed on the structure and function of the archaeal DNA replication origins, the proteins that define them, and the macromolecular

DNA Replication Fidelity [PDF]
Annual Review of Biochemistry, 2000 ▪ Abstract DNA replication fidelity is a key determinant of genome stability and is central to the evolution of species and to the origins of human diseases. Here we review our current understanding of replication fidelity, with emphasis on structural and biochemical studies of DNA polymerases that provide new insights into the importance of hydrogen

Tau acetylation at K331 has limited impact on tau pathology in vivo
FEBS Letters, EarlyView.We mapped tau post‐translational modifications in humanized MAPT knock‐in mice and in amyloid‐bearing double knock‐in mice. Acetylation within the repeat domain, particularly around K331, showed modest increases under amyloid pathology. To test functional relevance, we generated MAPTK331Q knock‐in mice.

PolySUMOylation of PCNA and Rad52 restricts centromeric recombination in fission yeast
Nature CommunicationsSUMOylation, a conserved post-translational modification in eukaryotes, regulates protein function, localization, and stability. However, the role of SUMO chains in genome maintenance is still emerging.
