  Evaluation Summary:

  This study is of interest to the broader audience of cell biologists, as it aims to dissect the hierarchy of protein recruitment and lipid conversion events that may provide a potential mechanism for the formation, maturation and fate of macropinosomes. The conclusions are based on the observation that pharmacological inhibition of the lipid kinase VPS34, which generates the signalling lipid PI3P on endosomes, prevents accumulation of Rab5 on macropinosomes, blocking their maturation and causing them to re-fuse with the plasma membrane.

  Evaluation Summary:

  This paper is of broad interest to readers interested in motile cilia and cargo transport mediated by intraflagellar transport (IFT). It examines how radial spokes are trafficked into cilia by IFT, which represents a key process in the assembly of motile cilia. The authors demonstrate that an adaptor protein (ARMC2) is needed for association of radial spokes with the IFT machinery. They also find that the interaction of ARMC2/radial spokes with individual IFT trains (or particles) occurs in a stochastic manner rather than there being a specialized subset of trains specifically designated for a particular cargo. The results support the key claims in the paper.

  Evaluation Summary:

  Ribosomal proteins are prone to aggregation. This work provides strong experimental support for a novel mechanism by which the level of the mRNA encoding two different ribosomal proteins is fine-tuned by variation in the abundance or availability of their chaperones. This regulation is proposed to operate through mRNA degradation at the translating ribosome. The data are extensive - from genetic observations that hint at the existence of a feedback loop, through interaction mechanisms, to biological significance. The logical links between the different steps in the analysis are clear, sound and well set out. The conclusions are unanticipated, but convincingly supported and very likely relevant and important for other systems beyond yeast.
