  This work describes a valuable new technique involving proximity labelling to identify Drosophila proteins modified by GlcNAcylation in subsets of cells in vivo. A solid set of experiments shows that several ribosomal proteins are modified in the fly mushroom body. Consistent with a role for GlcNAcylation of ribosomal proteins in control of memory related translational control, the authors show that perturbation of GlcNAc modification in KCs prevents efficient consolidation of long-term memory.

  This valuable study advances our understanding that YAP/TAZ, as well as their target genes, play a prominent role in the formation of processing bodies (P-bodies). The evidence supporting the conclusions is convincing. The article could be improved through further analysis to elucidate the mechanistic link between P-body formation and oncogenesis. The work will be of broad interest to scientists working in the field of Hippo signaling and cancer biology.

  eLife assessment

  This valuable paper examines the role of the WRNIP1 AAA+ ATPase in regulating R-loop formation, which induces a conflict with active replication forks and transcription. The authors provide convincing evidence to support a role of the ubiquitin-binding UBZ domain of WRNIP1 in R-loop suppression generated by this conflict. The work is of interest to researchers who work on genome stability/instability.

Early recovery of proteasome activity in cells pulse-treated with proteasome inhibitors is independent of DDI2

• Curated by eLife

  eLife assessment

  The study presents important findings regarding a transcription-independent component of the early recovery of proteasome activity from a short pulse of proteasome inhibitor treatment, which has not been appreciated before and which is independent of the DDI2-NRF2 axis. While the evidence is in principle solid, with recapitulation in several cell line models, the proposed alternative underlying mechanism, namely regulation at the level of proteasome assembly, lacks experimental support, and at this point remain speculative.

  This work presents important insights regarding the mechanism underlying the assembly, maintenance, and disassembly of a very stable microtubule-based structure, termed quiescent-cell nuclear microtubule (Q-nMT) bundle, which is formed in quiescent yeast cells to ensure cell survival and viability. This insight will help to elucidate how very stable microtubules can exist alongside very dynamic microtubules, which is still poorly understood. While the experimental support is overall solid, additional analyses using state-of-the-art methodology would further strengthen some of the claims.
