  This paper presents valuable findings on how autophagosomes are positioned along microtubules for their efficient fusion with lysosomes, providing significant insights into the mechanism. The evidence supporting the conclusions is solid, with high-quality fluorescence microscopy combined with Drosophila genetics. This work will be of broad interest to cell biologists interested in autophagy and related cell biology fields.

  This important study shows that calcium stores in the endoplasmic reticulum of the parasitic protozoan, Toxoplasma gondii play a major role in buffering calcium levels in the cytosol as well as other organelles such as the mitochondrion. Advanced imaging techniques, including use of genetically encoded calcium indicators provide compelling evidence for the role of the SERCA-Ca2+ ATPase pump in regulating organellar calcium levels. However, it remains unclear whether intra-organellar calcium transport occurs via ER-mitochondria membrane contact sites or other mechanisms. This work will be of interest to cell and molecular biologists interested in calcium signalling in divergent eukaryotes.

Treacle and MDC1 coordinate rDNA break repair by homologous recombination

• Curated by eLife

  eLife Assessment

  This manuscript reports valuable results on the role of MDC1 and Treacle in DSB repair in rDNA repeats. It has been previously established that MDC1 is replaced by Treacle as the main adaptor in the nucleolar DNA damage response. This work provides convincing evidence that MDC1 is required for the recruitment of RAD51 and BRCA1 to DSBs in rDNA. The work involves multiple MDC1 knockout models and establishes that RFN8-RNF168 act downstream of MDC1 in the recruitment of the HR machinery to nucleolar DSBs.

Canonical and phosphoribosyl ubiquitination coordinate to stabilize a proteinaceous structure surrounding the Legionella-containing vacuole

• Curated by eLife

  eLife Assessment

  This manuscript presents a valuable and insightful contribution to the understanding of how Legionella pneumophila remodels its vacuolar niche through coordinated ubiquitination mechanisms. The identification of Rab5 as a target of both canonical and phosphoribosyl ubiquitination, and the demonstration of a detergent-resistant ubiquitin "cloud" surrounding the LCV, represent significant advances in the field. The findings are supported by rigorous experimental design, robust quantitative analyses, and clear mechanistic insight, meeting a standard of evidence that is compelling and exceeds current state-of-the-art approaches.

  eLife Assessment

  This fundamental study reveals that aging in yeast leads to chromosome mis-segregation due to asymmetric partitioning of chromosomes, driven by disruption of the nuclear pore complex and pre-mRNA leakage. The findings are convincingly supported by carefully-designed experimental data with a combination of genetic, molecular biology and cell biology approaches.

  eLife Assessment

  This valuable study combines microscopy and CRISPR screening in two different cell lines to identify factors involved in global chromatin organization, using centromere clustering as a proxy. Follow-up cell cycle synchronisation studies confirm roles in centromere clustering in mitosis. However, incomplete characterisation of the cell lines used limits the interpretation of the findings. The study will interest researchers studying genome organisation in mitosis.
