Two-tiered enforcement of high-fidelity DNA ligation

Nature Communications, 2019
DNA ligases catalyze the joining of DNA strands to complete DNA replication, recombination and repair transactions. Here the authors present X-ray structures and kinetic analyses of LIG1 complexes with undamaged and oxidatively damaged DNA that unveil ...

Global-genome Nucleotide Excision Repair Controlled by Ubiquitin/Sumo Modifiers

Frontiers in Genetics, 2016
Global-genome nucleotide excision repair (GG-NER) prevents genome instability by excising a wide range of structurally unrelated DNA base adducts and crosslinks induced by chemical carcinogens, ultraviolet (UV) radiation or intracellular metabolic by ...

Parkin-independent mitophagy controls chemotherapeutic response in cancer cells [PDF]

, 2017
Mitophagy is an evolutionarily conserved process that selectively targets impaired mitochondria for degradation. Defects in mitophagy are often associated with diverse pathologies, including cancer.

UBP12 and UBP13 negatively regulate the activity of the ubiquitin-dependent peptidases DA1, DAR1 and DAR2 [PDF]

, 2020
Protein ubiquitination is a very diverse post-translational modification leading to protein degradation or delocalization, or altering protein activity. In Arabidopsis thaliana, two E3 ligases, BIG BROTHER (BB) and DA2, activate the latent peptidases DA1,

An improved protocol for small RNA library construction using High Definition adapters [PDF]

, 2015
Next generation sequencing of small RNA (sRNA) libraries is widely used for studying sRNAs in various biological systems. However, cDNA libraries of sRNAs are biased for molecules that are ligated to adapters more or less efficiently than other molecules.

The COP9 SIGNALOSOME is required for postembryonic meristem maintenance in Arabidopsis thaliana [PDF]

, 2015
Cullin-RING E3 ligases (CRLs) regulate different aspects of plant development, and are activated by modification of their cullin subunit with the ubiquitin-like protein NEDD8 (NEural precursor cell expressed Developmentally Down-regulated 8) (neddylation)

Reciprocal control of viral infection and phosphoinositide dynamics

FEBS Letters, EarlyView.
Phosphoinositides, although scarce, regulate key cellular processes, including membrane dynamics and signaling. Viruses exploit these lipids to support their entry, replication, assembly, and egress. The central role of phosphoinositides in infection highlights phosphoinositide metabolism as a promising antiviral target.

Water-soluble version of SCR7-pyrazine inhibits DNA repair and abrogates tumor cell proliferation

Journal of Radiation and Cancer Research, 2019
Aim: Mammalian DNA Ligases play pivotal role in processes such as DNA replication, recombination, and repair, which qualifies them as potent therapeutic targets to eradicate cancer cells.

Tankyrases Promote Homologous Recombination and Check Point Activation in Response to DSBs. [PDF]

PLoS Genetics, 2016
DNA lesions are sensed by a network of proteins that trigger the DNA damage response (DDR), a signaling cascade that acts to delay cell cycle progression and initiate DNA repair.

Rat liver DNA ligases [PDF]

European Journal of Biochemistry, 1992
A novel form of rat liver DNA ligase (molecular mass 100 kDa) can be differentiated from DNA ligase I by several biochemical parameters. It is a more heat‐labile enzyme and unable to join bluntended DNA, even in the presence of poly(ethylene glycol) concentrations which stimulate such joining by DNA ligase I and T4 DNA ligase.
