  This manuscript provides an important advance in our understanding of the molecular events that promote osteoclast fusion. Compelling data support the conclusion that an oxidized form of the ubiquitous protein La promotes osteoclast fusion following enrichment at the cell surface of osteoclast progenitors. These data improve our understanding of the processes that regulate bone resorption and will be of broad interest to researchers in the fields of cell biology and musculoskeletal physiology.

S-acylation of NLRP3 provides a nigericin sensitive gating mechanism that controls access to the Golgi

• Curated by eLife

  eLife assessment

  This important paper implicates S-acylation of Cys-130 in recruitment of the inflammasome receptor NLRP3 to the Golgi, and it provides convincing evidence that S-acylation plays a key role in response to the stress induced by nigericin treatment. While Cys-130 does seem to play a previously unappreciated role in membrane association of NLRP3, further work will be needed to clarify the details of the mechanism.

Time-resolved proximity proteomics uncovers a membrane tension-sensitive caveolin-1 interactome at the rear of migrating cells

• Curated by eLife

  eLife assessment

  This important study uses convincing time-resolved proximity proteomics, validated with proximity ligation assays, to provide new insight into mechanical regulation of caveolin-1 complexes that form in migrating cells. Solid follow up experiments reveal a reciprocal relationship between mechanosensitive caveolae and RhoGTPase signalling in migrating cells, but evidence supporting a direct link between the newly identified factors with a specific caveolae subpopulation remains incomplete at this stage.

  The authors present a useful analysis of the phenotype of sheep in which the muscle developmental regulator myostatin has been mutated in a FGF5 knockout background. The goal was to produce sheep with a "double-muscled" phenotype, yet the genetically engineered sheep exhibited meat with a smaller cross-sectional area and higher number of muscle fibers. The work extends the extensive body of knowledge already published in this area. The authors provide evidence using in vitro experiments that Fosl1 regulates myogenesis, but the strength of evidence relating to the muscle phenotype and underlying cellular and molecular mechanism remains incomplete.

  This study presents solid results to demonstrate that arpin is expressed in the endothelium of blood vessels and that its deficiency leads to leaky blood vessels in in vivo and in vitro models. The work does not yet clarify the mechanistic connection between arpin and increased ROCK activity. The study adds some insights to our understanding of the complicated network of proteins that control this process, and it will be useful to individuals within this defined field of study.
