Strengths and Challenges of Secretory Ribonucleases as AntiTumor Agents
Approaches to develop effective drugs to kill cancer cells are mainly focused either on the improvement of the currently used chemotherapeutics or on the development of targeted therapies aimed at the selective destruction of cancer cells by steering ...

Mapping the evolution of mitochondrial complex I through structural variation
Respiratory complex I (CI) is crucial for bioenergetic metabolism in many prokaryotes and eukaryotes. It is composed of a conserved set of core subunits and additional accessory subunits that vary depending on the organism. Here, we categorize CI subunits from available structures to map the evolution of CI across eukaryotes. Respiratory complex I (CI)

The evolutionary history of plant T2/S-type ribonucleases [PDF]
A growing number of T2/S-RNases are being discovered in plant genomes. Members of this protein family have a variety of known functions, but the vast majority are still uncharacterized.

An intracellular transporter mitigates the CO2‐induced decline in iron content in Arabidopsis shoots
This study identifies a gene encoding a transmembrane protein, MIC, which contributes to the reduction of shoot Fe content observed in plants under elevated CO2. MIC is a putative Fe transporter localized to the Golgi and endosomal compartments. Its post‐translational regulation in roots may represent a potential target for improving plant nutrition ...

Immune Modulation by Human Secreted RNases at the Extracellular Space
The ribonuclease A superfamily is a vertebrate-specific family of proteins that encompasses eight functional members in humans. The proteins are secreted by diverse innate immune cells, from blood cells to epithelial cells and their levels in our body ...

Decay-Initiating Endoribonucleolytic Cleavage by RNase Y Is Kept under Tight Control via Sequence Preference and Sub-cellular Localisation. [PDF]
Bacteria depend on efficient RNA turnover, both during homeostasis and when rapidly altering gene expression in response to changes. Nevertheless, remarkably few details are known about the rate-limiting steps in targeting and decay of RNA.

Crosstalk between the ribosome quality control‐associated E3 ubiquitin ligases LTN1 and RNF10
Loss of the E3 ligase LTN1, the ubiquitin‐like modifier UFM1, or the deubiquitinating enzyme UFSP2 disrupts endoplasmic reticulum–ribosome quality control (ER‐RQC), a pathway that removes stalled ribosomes and faulty proteins. This disruption may trigger a compensatory response to ER‐RQC defects, including increased expression of the E3 ligase RNF10 ...

The article dwells on ribonucleases (RNAses) whose cytotoxic activity depends on the enzymatic activity, i.e. the ability to catalyze the cleavage of phosphodiester bonds of RNA.

Secreted alkaline ribonucleases of micromycetes
Many ribonucleases (RNases) have a selective cytotoxic effect on tumor cells. Of particular interest are enzymes that are phylogenetically distant from mammalian RNases, such as amphibian, fungal, and bacterial RNases, all insensitive to the action of ...

Senescent cells limit p53 activity via multiple mechanisms to remain viable
To develop therapeutics that selectively eliminate pathological senescent cells it is important to understand their survival mechanisms. Here, the authors show that senescent cells manage to survive by keeping p53 activity in check through multiple ...
