Orlando D Schärer Published online 28.06.2017 Survivor: Ribosome Edition Two recent studies reveal the structural basis for ribosome hibernation, a process by which bacteria form inactive ribosome dimers to survive environmental stress. Ruben L Gonzalez, Jr Published online 03.07.2017 Review Focus: Metabolism: Adipose tissue: between the extremes This part of our Metabolism review series highlights both the physiological roles of adipose tissue and the pathological consequences of its dysfunction. Alexandros Vegiopoulos, Maria Rohm, and Stephan Herzig Published online 16.06.2017 Articles ER–plasma membrane contact sites contribute to autophagosome biogenesis by regulation of local PI3P synthesis Early autophagic markers are recruited to endoplasmic reticulum‐plasma membrane (ER‐PM) contact sites established by tethering factors extended synaptotagmins, allowing for local phosphatidylinositol‐3‐phosphate synthesis and autophagosome biogenesis. Anna Chiara Nascimbeni, Francesca Giordano, Nicolas Dupont, Daniel Grasso, Maria I Vaccaro, Patrice Codogno, and Etienne Morel Published online 26.05.2017 Recruitment and positioning determine the specific role of the XPF‐ERCC1 endonuclease in interstrand crosslink repair Patient‐derived and separation‐of‐function mutations distinguish nucleotide excision repair and interstrand crosslink repair roles of a key structure‐specific endonuclease. Daisy Klein Douwel, Wouter S Hoogenboom, Rick ACM Boonen, and Puck Knipscheer Published online 14.03.2017 RPA activates the XPF‐ERCC1 endonuclease to initiate processing of DNA interstrand crosslinks Unhooking of interstrand crosslinks on DNA structures mimicking arrested replication fork requires incision nuclease collaboration with replication protein A. Ummi B Abdullah, Joanna F McGouran, Sanja Brolih, Denis Ptchelkine, Afaf H El‐Sagheer, Tom Brown, and Peter J McHugh Published online 12.06.2017 Structure of the Bacillus subtilis hibernating 100S ribosome reveals the basis for 70S dimerization The structure of two ribosomes held together by hibernation promotion factor reveals how bacteria form inactive 100S disomes to limit translation when entering stationary phase. Bertrand Beckert, Maha Abdelshahid, Heinrich Schäfer, Wieland Steinchen, Stefan Arenz, Otto Berninghausen, Roland Beckmann, Gert Bange, Kürşad Turgay, and Daniel N Wilson Published online 03.05.2017 Structures and dynamics of hibernating ribosomes from Staphylococcus aureus mediated by intermolecular interactions of HPF By combining cryoEM and NMR, this study illustrates how bacterial ribosomes are stored in an inactive dimeric 100S (disome) state during stress responses. Iskander Khusainov, Quentin Vicens, Rustam Ayupov, Konstantin Usachev, Alexander Myasnikov, Angelita Simonetti, Shamil Validov, Bruno Kieffer, Gulnara Yusupova, Marat Yusupov, and Yaser Hashem Published online 23.06.2017 Phosphorylation of Argonaute proteins affects mRNA binding and is essential for microRNA‐guided gene silencing in vivo The discovery of a conserved phosphorylation site in Argonaute 2, a key effector of miRNA‐dependent gene regulation, reveals a new level of active control in the RNA silencing machinery. Miguel Quévillon Huberdeau, Daniela M Zeitler, Judith Hauptmann, Astrid Bruckmann, Lucile Fressigné, Johannes Danner, Sandra Piquet, Nicholas Strieder, Julia C Engelmann, Guillaume Jannot, Rainer Deutzmann, Martin J Simard, and Gunter Meister Published online 23.06.2017 A TRPV1‐to‐secretagogin regulatory axis controls pancreatic β‐cell survival by modulating protein turnover Calcium channel‐dependent induction of the calcium sensor secretagogin regulates insulin secretion not merely via the SNARE machinery, but also through the interacting deubiquitinase USP9X preventing ER stress and β‐cell loss. Katarzyna Malenczyk, Fatima Girach, Edit Szodorai, Petter Storm, Åsa Segerstolpe, Giuseppe Tortoriello, Robert Schnell, Jan Mulder, Roman A Romanov, Erzsébet Borók, Fabiana Piscitelli, Vincenzo Di Marzo, Gábor Szabó, Rickard Sandberg, Stefan Kubicek, Gert Lubec, Tomas Hökfelt, Ludwig Wagner, Leif Groop, and Tibor Harkany Published online 21.06.2017 OPA1 deficiency promotes secretion of FGF21 from muscle that prevents obesity and insulin resistance Local deletion of OPA1 in differentiated muscle evokes mitochondrial dysfunction and ER stress but concomitantly induces FGF21 and favorable metabolism in aged mice. Renata Oliveira Pereira, Satya M Tadinada, Frederick M Zasadny, Karen Jesus Oliveira, Karla Maria Pereira Pires, Angela Olvera, Jennifer Jeffers, Rhonda Souvenir, Rose Mcglauflin, Alec Seei, Trevor Funari, Hiromi Sesaki, Matthew J Potthoff, Christopher M Adams, Ethan J Anderson, and E Dale Abel Published online 12.06.2017 Autotaxin–lysophosphatidic acid–LPA3 signaling at the embryo‐epithelial boundary controls decidualization pathways Interaction of preimplantation embryo and uterine epithelium facilitates synthesis of lysophosphatidic acid, which triggers HB‐EGF and SOX‐2 signal required for implantation in the uterus.
