Separase prevents genomic instability by controlling replication fork speed [PDF]

open access: yes, 2016
Proper chromosome segregation is crucial for preserving genomic integrity, and errors in this process cause chromosome mis-segregation, which may contribute to cancer development.

The (Glg)ABCs of cyanobacteria: modelling of glycogen synthesis and functional divergence of glycogen synthases in Synechocystis sp. PCC 6803

open access: yesFEBS Letters, EarlyView.
We reconstituted Synechocystis glycogen synthesis in vitro from purified enzymes and showed that two GlgA isoenzymes produce glycogen with different architectures: GlgA1 yields denser, highly branched glycogen, whereas GlgA2 synthesizes longer, less‐branched chains.

Dynamics of \u3cem\u3eE. Coli\u3c/em\u3e Single Stranded DNA Binding (SSB) Protein-DNA Complexes [PDF]

open access: yes, 2018
Single stranded DNA binding proteins (SSB) are essential to the cell as they stabilize transiently open single stranded DNA (ssDNA) intermediates, recruit appropriate DNA metabolism proteins, and coordinate fundamental processes such as replication ...

Plant DNA polymerases [PDF]

open access: yes, 2019
Maintenance of genome integrity is a key process in all organisms. DNA polymerases (Pols) are central players in this process as they are in charge of the faithful reproduction of the genetic information, as well as of DNA repair.

Organ‐specific redox imbalances in spinal muscular atrophy mice are partially rescued by SMN antisense oligonucleotides

open access: yesFEBS 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 ...

Association of lipid droplet and hepatitis C virus proteins: insights for virus replication [PDF]

open access: yesJournal of Lipid Research, 2013
Hepatitis C virus (HCV) infection represents a major worldwide disease burden, with an estimated prevalence of >185 million people (1). Among the various comorbidities associated with chronic HCV infection, hepatic steatosis is a frequent complication, and its presence is a key prognostic indicator associated with progression to hepatic fibrosis and ...

Human cytomegalovirus long noncoding RNA4.9 regulates viral DNA replication.

open access: yesPLoS Pathogens, 2020
Viruses are known for their extremely compact genomes composed almost entirely of protein-coding genes. Nonetheless, four long noncoding RNAs (lncRNAs) are encoded by human cytomegalovirus (HCMV).

The host-range tdCE phenotype of Chandipura virus is determined by mutations in the polymerase gene [PDF]

open access: yes
The emerging arbovirus Chandipura virus (CV) has been implicated in epidemics of acute encephalitis in India with high mortality rates. The isolation of temperature-dependent host-range (tdCE) mutants, which are impaired in growth at 39 °C in chick ...

Translesion synthesis in mammalian cells [PDF]

open access: yes, 2006
DNA damage blocks the progression of the replication fork. In order to circumvent the damaged bases, cells employ specialized low stringency DNA polymerases, which are able to carry out translesion synthesis (TLS) past different types of damage. The five

Tau acetylation at K331 has limited impact on tau pathology in vivo

open access: yesFEBS 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.
