• Curated by eLife

  eLife Assessment

  This important paper employs multiple experimental approaches and presents evidence that changes in membrane voltage directly affect ERK signaling to regulate cell division. This result is relevant because it supports an ion channel-independent pathway by which changes in membrane voltage can affect cell growth. The evidence now presented is solid and the data support the conclusions. This paper should be of interest to a broad readershp in the areas of cell and developemental biology and electrophysiology.

• Curated by eLife

  eLife Assessment

  This useful study investigates how intrinsically disordered domains can interact to dictate the sub-cellular localization of a major innate immune sensor termed cGAS. The data from various cellular and biochemical assays are mostly solid, but the main conclusions from these experiments need to be validated further. This paper is relevant to immunologists, especially those interested in cytosolic DNA-sensing pathways.

  eLife Assessment

  This interesting study adapts machine learning tools to analyze movements of a chromatin locus in living cells in response to serum starvation. The machine learning approach developed is useful, the experiments are well controlled, and the data are solid. The study would be greatly strengthened by testing key predictions made using perturbation experiments. This work will be of interest to those studying chromosome biology and gene expression patterns.

  eLife Assessment

  This study by Lapao et al. uncovers a novel role for the Rab27A effector SYTL5 in regulating mitochondrial function and mitophagy under hypoxic conditions. Using a range of imaging and functional assays, the authors demonstrate that SYTL5 localizes to mitochondria in a Rab27A-dependent manner and impacts mitochondrial respiration and metabolic reprogramming. While the findings are solid and valuable in the area of cancer biology, further mechanistic clarity and improved imaging would strengthen the conclusions.

• Curated by eLife

  eLife Assessment

  This important study elucidates the role of the exocyst component EXOC6A at distinct stages of ciliogenesis, which advances our understanding of ciliary membrane remodeling and cilium formation. The authors provide solid evidence that EXOC6A interacts with myosin-Va and is dynamically recruited via dynein-, microtubule-, and actin-dependent mechanisms, to support proper formation of the ciliary membrane. The study will be of interest to cell biologists and other researchers interested in vesicular trafficking, organellar membrane dynamics, and ciliogenesis.
