  Evaluation Summary:

  This paper examines how cells control their size and will be interesting to scientists studying sizing mechanisms throughout biology. Using yeast cells as a model system, the authors show that an activator of the cell division cycle accumulates as cells grow until a threshold level of activator is achieved. The experiments are performed well, and the high-quality data will be useful for others in the field studying this signaling pathway.

Microtubule rescue at midzone edges promotes overlap stability and prevents spindle collapse during anaphase B

  Evaluation Summary:

  This study carefully quantifies microtubule dynamics during anaphase in the fission yeast S. pombe. The high quality data revealed two new observations: that microtubule rescue occurs preferentially at the edge of the midzone and that microtubule growth speed decreases when the nuclear membrane wraps around the spindle midzone in late anaphase. This sheds new light on the interplay between the nuclear membrane and the midspindle in closed mitosis, and the study will be of interest to cell biologists studying spindle dynamics and mitosis.

  Evaluation Summary:

  This paper describes the crystal structure of two key components of the autophagy system, the PI3P-binding protein WIPI2d in complex with its interaction region in the hATG8 E3 ligase scaffold component ATG16L1. The paper provides interesting new data and demonstrates the requirements for association of WIPI2d with membranes. Functional studies in cells provide evidence that mutation of residues at the interface for ATG16L1 binding affects function, although additional studies would support loss of function versus a dominant negative effect.

Selective sorting of microRNAs into exosomes by phase-separated YBX1 condensates

• Curated by eLife

  Evaluation Summary:

  The ribonucleoprotein YBX1 is required for sorting of miR-233 to exosomes. Here, the authors demonstrate that YBX1 undergoes liquid liquid phase separation (LLPS) both in vitro and in vivo and YBX1 droplets specifically partition miR-233 and mediate its packaging into exosomes. The authors also demonstrate a possible connection between YBX1 condensates and P-bodies during cargo sorting into EVs. Overall, this is an elegant study and with a few additional experiments to clarify the involvement of P bodies, the story will be of broad impact to those interested in LLPS and RNA packaging into exosomes.
