  This valuable study is focused on the requirement of the photoreceptor-specific tetraspanins, ROM1 and PRPH2, for the formation of light-sensitive membrane discs. The evidence supporting the claim that deficiency in one of the proteins can be compensated by the other is convincing, with both established and advanced techniques yielding results that will be of interest to those studying photoreceptor development and membrane curvature.

  This study and associated data is compelling, novel, important, and well-carried out. The study demonstrates a novel finding that different chemotherapeutic agents can induce nucleolar stress, which manifests with varying cellular and molecular characteristics. The study also proposes a mechanism for how a novel type of nucleolar stress driven by CDK inhibitors may be regulated. The study sheds light on the importance of nucleolar stress in defining the on-target and off-target effects of chemotherapy in normal and cancer cells.

  This important study combines in vitro experiments with simulations to identify the mechanisms governing modulation of microtubule dynamics by GTP hydrolysis. The authors introduce a convincing new approach by using a mixed GDP/GMPCPP lattice and varying GDP concentration to reveal that the nucleotide at the interface of two tubulin dimers determines the strength of the interaction between two dimers. Overall, the findings will be of interest to biophysicists and cell biologists, especially in the field of microtubule biology.

  This fundamental work substantially advances our understanding of how cells can tightly modulate small GTPase activity to build and maintain neighboring cytoskeletal structures, in this case microvilli. The evidence supporting these claims is compelling and is supported by both protein-protein interaction assays as well as cell biological studies. The work will be of interest to cell biologist studying the cytoskeleton as well as those interested in G-protein mediated regulation.
