Occupancy of the HbYX hydrophobic pocket is sufficient to induce gate opening in the archaeal 20S proteasomes

• Curated by eLife

  eLife Assessment

  This valuable manuscript describes cryo-EM structures of archaeal proteasomes that reveal insights into how occupancy of binding pockets on the 20S proteasome regulates proteasome gating. The evidence supporting these claims is convincing, although the extrapolation of these findings to the more complex eukaryotic proteasome may prove challenging. This work will be of high interest to researchers interested in proteasome structure and regulation.

  This important study presents an alternative platform for nanobody discovery using phage-displayed synthetic libraries. The evidence supporting the platform, which is used to isolate and validate nanobodies targeting Drosophila secreted proteins, is compelling. By making the library openly accessible, this provides an excellent resource to the wider scientific community. The paper presents a detailed protocol for nanobody screening; as this protocol is refined and optimized over time, this will increase the success rate for discovering nanobodies with improved properties using this alternative platform.

  This paper reports on a correlation between diminished cardiolipin content and the severity of steatohepatitis in human subjects. This is supported further by experimental evidence from mice in which the gene encoding a key enzyme in cardiolipin synthesis has been compromised in the liver. The correlations established between lipidology, mitochondrial function, and the induction of respiration and oxidative stress are notable and will be useful to researchers in the field. However, given that the causal relationship between lipid perturbation and the progression of steatohepatitis implied in the title has not been tested experimentally, the evidence supporting the paper's key conclusion is incomplete.

• Curated by eLife

  eLife Assessment

  In this important study, the authors conducted atomistic molecular dynamics simulations to probe the interactions between IRE and unfolded peptides. The results help reconcile contradicting experimental findings in the literature and offer mechanistic insights into the activation of the unfolded protein response. The level of evidence is considered solid, although the use of enhanced sampling and more quantitative analysis would further strengthen the conclusions.
