  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.

  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.

Large-scale identification of plasma membrane repair proteins revealed spatiotemporal cellular responses to plasma membrane damage

  eLife Assessment

  This work provides an important resource identifying 72 proteins as novel candidates for plasma membrane and/or cell wall damage repair in budding yeast, and describes the temporal coordination of exocytosis and endocytosis during the repair process. The data are convincing; however, additional experimental validation will better support the claim that repair proteins shuttle between the bud tip and the damage site.

  How secretion is regulated during cell division and how membrane trafficking factors cooperate with the cytoskeleton during cell division remain poorly understood. In this work the authors find protein-protein interactions and localization dependencies between the polymeric septin cytoskeleton and the exocyst complex, using fission yeast as a model organism and using alphafold 3 based structural predictions. The work provides a valuable body of new information that will be of great interest to the cell biology community. The evidence is solid and provides the authors and the community a framework to test if the identified interfaces reflect bona fide interaction sites in vivo and in vitro in future.

AXONAL distribution of mitochondria maintains neuronal autophagy during aging via eIF2β

  eLife Assessment

  In flies defective for axonal transport of mitochondria, the authors report the upregulation of one subunit, the beta subunit, of the heterotrimeric eIF2 complex via mass spectroscopy proteomics. Neuronal overexpression of eIF2β phenocopied aspects of neuronal dysfunction observed when axonal transport of mitochondria was compromised. Conversely, lowering eIF2β expression suppressed aspects of neuronal dysfunction. While these are intriguing and useful observations, technical weaknesses limit the interpretation. On balance, the evidence supporting the current claims is suggestive but incomplete, especially concerning the characterization of the eIF2 heterotrimer and the data regarding translational regulation.
