Description

EMBO Reports aims to provide high-quality scientific information in the very broadly defined area of molecular biology. EMBO Reports will have in three major sections: scientific reports reviews and science & society. The scientific reports shall be short high-quality papers of a maximum print-length of 5 pages. Papers of all areas of molecular biology will be welcome and the data presented will represent a major new insight into some aspect of molecular biology. Novelty will be a primary criterion as will the quality of the research that is reported. These papers will be reviewed and published rapidly as is in keeping with important primary scientific results. The review section will provide high-quality reviews of selected topics written by leading experts in the field. It will also report on papers of importance which are published in other scientific journals and in doing so will attempt to ensure that the material presented in EMBO Reports is appropriate for a broad readership. A particular emphasis will also be put on incisive reports of meetings at which the latest data are presented. The science & society section will be a mixture of information which is relevant to scientists working in the area of molecular biology discussion on topics which fall into the general category of the environment in which our research is performed and more in-depth articles in which specific scientific topics are dealt with in detail. By the combination of these sections EMBO Reports aims to be a leading widely read interesting journal which is synonymous with high-quality primary reports of research readable stimulating timely reviews and a forum for discussions which are of direct relevance to molecular biologists. In this way it complements the coverage to science which is provided by The EMBO Journal which has already shown the ability of EMBO to develop a journal of high quality in the area of molecular biology.

    ABSTRACT: In eukaryotes, the molecular chaperones Hsp90 and Hsp70 are connected via the co-chaperone Sti1/Hop, which allows transfer of clients. Here, we show that the basic functions of yeast Sti1 and human Hop are conserved. These include the simultaneous binding of Hsp90 and Hsp70, the inhibition of the ATPase activity of Hsp90, and the ability to support client activation in vivo. Importantly, we reveal that both Hop and Sti1 are subject to inhibitory phosphorylation, although the sites modified and the influence of regulatory phosphorylation is species specific. Phospho-mimetic variants have a reduced ability to activate clients in vivo and different affinity for Hsp70. Hop is more tightly regulated, as phosphorylation affects also the interaction with Hsp90 and induces structural rearrangements in the core part of the protein.

    ABSTRACT: The Catharanthus roseus Receptor-Like Kinase 1-like (CrRLK1L) family of 17 receptor-like kinases (RLKs) has been implicated in a variety of signaling pathways in Arabidopsis, ranging from pollen tube (PT) reception and tip growth to hormonal responses. The extracellular domains of these RLKs have malectin-like domains predicted to bind carbohydrate moieties. Domain swap analysis showed that the extracellular domains of the three members analyzed (FER, ANX1, HERK1) are not interchangeable, suggesting distinct upstream components, such as ligands and/or co-factors. In contrast, their intercellular domains are functionally equivalent for PT reception, indicating that they have common downstream targets in their signaling pathways. The kinase domain is necessary for FER function, but kinase activity itself is not, indicating that other kinases may be involved in signal transduction during PT reception.

    ABSTRACT: An effective immune response requires the engagement of host receptors by pathogen-derived molecules and the stimulation of an appropriate cellular response. Therefore, a crucial factor in our ability to control an infection is the accessibility of our immune cells to the foreign material. Exosomes—which are extracellular vesicles that function in intercellular communication—may play a key role in the dissemination of pathogen- as well as host-derived molecules during infection. In this review, we highlight the composition and function of exosomes and other extracellular vesicles produced during viral, parasitic, fungal and bacterial infections and describe how these vesicles could function to either promote or inhibit host immunity.

    ABSTRACT: Mitochondrial proteostasis is maintained by a network of ATP-dependent quality control proteases including the inner membrane protease YME1L. Here, we show that YME1L is a stress-sensitive mitochondrial protease that is rapidly degraded in response to acute oxidative stress. This degradation requires reductions in cellular ATP and involves the activity of the ATP-independent protease OMA1. Oxidative stress-dependent reductions in YME1L inhibit protective YME1L-dependent functions and increase cellular sensitivity to oxidative insult. Collectively, our results identify stress-induced YME1L degradation as a biologic process that attenuates protective regulation of mitochondrial proteostasis and promotes cellular death in response to oxidative stress.

    ABSTRACT: Recent studies have highlighted the importance of regulatory non-coding RNAs and epigenetics in controlling the differentiation of somatic stem cells. Two major pathways characterize these fields: micro-RNAs (miRNAs) and DNA methylation. In this issue of EMBO Reports, Lv et al show that during mammalian corticogenesis, miR-15b inhibits cytosine demethylation by targeting Tet3, a key methylcytosine dioxygenase. This leads to the epigenetic downregulation of cyclin D1. As a result, cell cycle and differentiation of neural progenitors are altered, promoting their switch to neurogenesis. Hence, Lv et al elegantly bring together miRNAs and DNA methylation in the cell cycle control of neural progenitors and neurogenesis.

    ABSTRACT: RNA ligation can regulate RNA function by altering RNA sequence, structure and coding potential. For example, the function of XBP1 in mediating the unfolded protein response requires RNA ligation, as does the maturation of some tRNAs. Here, we describe a novel in vivo model in Caenorhabditis elegans for the conserved RNA ligase RtcB and show that RtcB ligates the xbp-1 mRNA during the IRE-1 branch of the unfolded protein response. Without RtcB, protein stress results in the accumulation of unligated xbp-1 mRNA fragments, defects in the unfolded protein response, and decreased lifespan. RtcB also ligates endogenous pre-tRNA halves, and RtcB mutants have defects in growth and lifespan that can be bypassed by expression of pre-spliced tRNAs. In addition, animals that lack RtcB have defects that are independent of tRNA maturation and the unfolded protein response. Thus, RNA ligation by RtcB is required for the function of multiple endogenous target RNAs including both xbp-1 and tRNAs. RtcB is uniquely capable of performing these ligation functions, and RNA ligation by RtcB mediates multiple essential processes in vivo.

    ABSTRACT: The study of conserved protein interaction networks seeks to better understand the evolution and regulation of protein interactions. Here, we present a quantitative proteomic analysis of 18 orthologous baits from three distinct chromatin-remodeling complexes in Saccharomyces cerevisiae and Homo sapiens. We demonstrate that abundance levels of orthologous proteins correlate strongly between the two organisms and both networks have highly similar topologies. We therefore used the protein abundances in one species to cross-predict missing protein abundance levels in the other species. Lastly, we identified a novel conserved low-abundance subnetwork further demonstrating the value of quantitative analysis of networks.

    ABSTRACT: Mutations in leucine-rich repeat kinase 2 (LRRK2) are the most common cause of dominant-inherited Parkinson's disease (PD), and yet we do not fully understand the physiological function(s) of LRRK2. Various components of the clathrin machinery have been recently found mutated in familial forms of PD. Here, we provide molecular insight into the association of LRRK2 with the clathrin machinery. We report that through its GTPase domain, LRRK2 binds directly to clathrin-light chains (CLCs). Using genome-edited HA-LRRK2 cells, we localize LRRK2 to endosomes on the degradative pathway, where it partially co-localizes with CLCs. Knockdown of CLCs and/or LRRK2 enhances the activation of the small GTPase Rac1, leading to alterations in cell morphology, including the disruption of neuronal dendritic spines. In Drosphila, a minimal rough eye phenotype caused by overexpression of Rac1, is dramatically enhanced by loss of function of CLC and LRRK2 homologues, confirming the importance of this pathway in vivo. Our data identify a new pathway in which CLCs function with LRRK2 to control Rac1 activation on endosomes, providing a new link between the clathrin machinery, the cytoskeleton and PD.

    ABSTRACT: Pluripotency-associated transcription factor Foxd3 is required for maintaining pluripotent cells. However, molecular mechanisms underlying its function are largely unknown. Here, we report that Foxd3 suppresses differentiation induced by calcineurin–NFAT signaling to maintain the ESC identity. Mechanistically, Foxd3 interacts with NFAT proteins and recruits co-repressor Tle4, a member of the Tle repressor family highly expressed in undifferentiated ESCs, to suppress NFATc3's transcriptional activities. Furthermore, global transcriptome analysis shows that Foxd3 and NFATc3 co-regulate a set of differentiation-associated genes in ESCs. Collectively, our study establishes a molecular and functional link between a pluripotency-associated factor and an important ESC differentiation-inducing pathway.

    ABSTRACT: The transcription factor HIF-1α is essential for cells to rapidly adapt to low oxygen levels (hypoxia). HIF-1α is frequently deregulated in cancer and correlates with poor patient prognosis. Here, we demonstrate that the deubiquitinase Cezanne regulates HIF-1α homeostasis. Loss of Cezanne decreases HIF-1α target gene expression due to a reduction in HIF-1α protein levels. Surprisingly, although the Cezanne-regulated degradation of HIF-1α depends on the tumour suppressor pVHL, hydroxylase and proteasome activity are dispensable. Our data suggest that Cezanne is essential for HIF-1α protein stability and that loss of Cezanne stimulates HIF-1α degradation via proteasome-independent routes, possibly through chaperone-mediated autophagy.

    ABSTRACT: Phosphoinositides are a class of phospholipids generated by the action of phosphoinositide kinases with key regulatory functions in eukaryotic cells. Here, we present the atomic structure of phosphatidylinositol 4-kinase type IIα (PI4K IIα), in complex with ATP solved by X-ray crystallography at 2.8 Å resolution. The structure revealed a non-typical kinase fold that could be divided into N- and C-lobes with the ATP binding groove located in between. Surprisingly, a second ATP was found in a lateral hydrophobic pocket of the C-lobe. Molecular simulations and mutagenesis analysis revealed the membrane binding mode and the putative function of the hydrophobic pocket. Taken together, our results suggest a mechanism of PI4K IIα recruitment, regulation, and function at the membrane.
