  This fundamental study describes the mechanisms for regulation of the phosphate starvation response in baker's yeast, clarifies the interpretations of prior data, and suggests a unifying mechanism across eukaryotes. The study provides compelling data, based on biochemical analyses, protein localization by fluorescence, and genetic approaches that 1,5-InsP8 is the phosphate nutrient messenger in yeast.

  This is a useful study for scientists interested in cell polarity, epithelial morphogenesis, cancer, and primary cilia. The authors investigate the role of CRB3 in regulating these processes by using a combination of a mammary epithelial cell-specific conditional Crb3 knockout mouse model, and cellular, molecular and biochemical approaches. The results, which are solid, supporting and extending previous findings, suggest that CRB3 affects ciliogenesis by a mechanism involving Rab11 and gamma-TuRC.

  eLife assessment

  This important study combines conditional mutagenesis with proximity labeling to evaluate alterations in a sub-cellular proteome upon a perturbing event. The approach is applied to the deletion of a kinase involved in trafficking of adhesins to the malaria parasite-infected erythrocyte surface and the evidence supporting the conclusions is compelling. The work will be of broad interest to cell biologists and biochemists.

  eLife assessment

  This valuable study shows that Rab12 is required for LRRK2 activation. However, while some of the data are compelling, some claims, especially the ones related to LRRK2's membrane association are not supported. Addressing discrepancies between figures (pointed out by reviewers) and re-writing certain sections will greatly improve this manuscript.

• Curated by eLife

  eLife assessment

  This valuable study combines live cell imaging and mathematical modeling to show how an emerging model fungus engages in an oscillatory chemical dialogue to prepare for cell-cell fusion. Cell data and modeling are in compelling agreement but leave many open questions as to the nature of coordination between cells and the significance of oscillations, rendering the strength of evidence in support of the authors' inferences incomplete.
