    Structure of the formate transporter FocA reveals a pentameric aquaporin-like channel (2009)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2009-11-27
    Description: FocA is a representative member of the formate-nitrite transporter family, which transports short-chain acids in bacteria, archaea, fungi, algae and parasites. The structure and transport mechanism of the formate-nitrite transporter family remain unknown. Here we report the crystal structure of Escherichia coli FocA at 2.25 A resolution. FocA forms a symmetric pentamer, with each protomer consisting of six transmembrane segments. Despite a lack of sequence homology, the overall structure of the FocA protomer closely resembles that of aquaporin and strongly argues that FocA is a channel, rather than a transporter. Structural analysis identifies potentially important channel residues, defines the channel path and reveals two constriction sites. Unlike aquaporin, FocA is impermeable to water but allows the passage of formate. A structural and biochemical investigation provides mechanistic insights into the channel activity of FocA.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Wang, Yi -- Huang, Yongjian -- Wang, Jiawei -- Cheng, Chao -- Huang, Weijiao -- Lu, Peilong -- Xu, Ya-Nan -- Wang, Pengye -- Yan, Nieng -- Shi, Yigong -- England -- Nature. 2009 Nov 26;462(7272):467-72. doi: 10.1038/nature08610.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Ministry of Education Protein Science Laboratory, Center for Structural Biology, School of Life Sciences and School of Medicine, Tsinghua University, Beijing 100084, China.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19940917" target="_blank"〉PubMed〈/a〉

    Deubiquitinase DUBA is a post-translational brake on interleukin-17 production in T cells (2014)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2014-12-04
    Description: T-helper type 17 (TH17) cells that produce the cytokines interleukin-17A (IL-17A) and IL-17F are implicated in the pathogenesis of several autoimmune diseases. The differentiation of TH17 cells is regulated by transcription factors such as RORgammat, but post-translational mechanisms preventing the rampant production of pro-inflammatory IL-17A have received less attention. Here we show that the deubiquitylating enzyme DUBA is a negative regulator of IL-17A production in T cells. Mice with DUBA-deficient T cells developed exacerbated inflammation in the small intestine after challenge with anti-CD3 antibodies. DUBA interacted with the ubiquitin ligase UBR5, which suppressed DUBA abundance in naive T cells. DUBA accumulated in activated T cells and stabilized UBR5, which then ubiquitylated RORgammat in response to TGF-beta signalling. Our data identify DUBA as a cell-intrinsic suppressor of IL-17 production.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Rutz, Sascha -- Kayagaki, Nobuhiko -- Phung, Qui T -- Eidenschenk, Celine -- Noubade, Rajkumar -- Wang, Xiaoting -- Lesch, Justin -- Lu, Rongze -- Newton, Kim -- Huang, Oscar W -- Cochran, Andrea G -- Vasser, Mark -- Fauber, Benjamin P -- DeVoss, Jason -- Webster, Joshua -- Diehl, Lauri -- Modrusan, Zora -- Kirkpatrick, Donald S -- Lill, Jennie R -- Ouyang, Wenjun -- Dixit, Vishva M -- England -- Nature. 2015 Feb 19;518(7539):417-21. doi: 10.1038/nature13979.

    Propagation of conformational changes during mu-opioid receptor activation (2015)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2015-08-08
    Description: micro-Opioid receptors (microORs) are G-protein-coupled receptors that are activated by a structurally diverse spectrum of natural and synthetic agonists including endogenous endorphin peptides, morphine and methadone. The recent structures of the muOR in inactive and agonist-induced active states (Huang et al., ref. 2) provide snapshots of the receptor at the beginning and end of a signalling event, but little is known about the dynamic sequence of events that span these two states. Here we use solution-state NMR to examine the process of muOR activation using a purified receptor (mouse sequence) preparation in an amphiphile membrane-like environment. We obtain spectra of the muOR in the absence of ligand, and in the presence of the high-affinity agonist BU72 alone, or with BU72 and a G protein mimetic nanobody. Our results show that conformational changes in transmembrane segments 5 and 6 (TM5 and TM6), which are required for the full engagement of a G protein, are almost completely dependent on the presence of both the agonist and the G protein mimetic nanobody, revealing a weak allosteric coupling between the agonist-binding pocket and the G-protein-coupling interface (TM5 and TM6), similar to that observed for the beta2-adrenergic receptor. Unexpectedly, in the presence of agonist alone, we find larger spectral changes involving intracellular loop 1 and helix 8 compared to changes in TM5 and TM6. These results suggest that one or both of these domains may play a role in the initial interaction with the G protein, and that TM5 and TM6 are only engaged later in the process of complex formation. The initial interactions between the G protein and intracellular loop 1 and/or helix 8 may be involved in G-protein coupling specificity, as has been suggested for other family A G-protein-coupled receptors.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Sounier, Remy -- Mas, Camille -- Steyaert, Jan -- Laeremans, Toon -- Manglik, Aashish -- Huang, Weijiao -- Kobilka, Brian K -- Demene, Helene -- Granier, Sebastien -- DA036246/DA/NIDA NIH HHS/ -- R37 DA036246/DA/NIDA NIH HHS/ -- T32 GM008294/GM/NIGMS NIH HHS/ -- England -- Nature. 2015 Aug 20;524(7565):375-8. doi: 10.1038/nature14680.

    DDX5 and its associated lncRNA Rmrp modulate TH17 cell effector functions (2015)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2015-12-18
    Description: T helper 17 (TH17) lymphocytes protect mucosal barriers from infections, but also contribute to multiple chronic inflammatory diseases. Their differentiation is controlled by RORgammat, a ligand-regulated nuclear receptor. Here we identify the RNA helicase DEAD-box protein 5 (DDX5) as a RORgammat partner that coordinates transcription of selective TH17 genes, and is required for TH17-mediated inflammatory pathologies. Surprisingly, the ability of DDX5 to interact with RORgammat and coactivate its targets depends on intrinsic RNA helicase activity and binding of a conserved nuclear long noncoding RNA (lncRNA), Rmrp, which is mutated in patients with cartilage-hair hypoplasia. A targeted Rmrp gene mutation in mice, corresponding to a gene mutation in cartilage-hair hypoplasia patients, altered lncRNA chromatin occupancy, and reduced the DDX5-RORgammat interaction and RORgammat target gene transcription. Elucidation of the link between Rmrp and the DDX5-RORgammat complex reveals a role for RNA helicases and lncRNAs in tissue-specific transcriptional regulation, and provides new opportunities for therapeutic intervention in TH17-dependent diseases.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4762670/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4762670/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Huang, Wendy -- Thomas, Benjamin -- Flynn, Ryan A -- Gavzy, Samuel J -- Wu, Lin -- Kim, Sangwon V -- Hall, Jason A -- Miraldi, Emily R -- Ng, Charles P -- Rigo, Frank W -- Meadows, Sarah -- Montoya, Nina R -- Herrera, Natalia G -- Domingos, Ana I -- Rastinejad, Fraydoon -- Myers, Richard M -- Fuller-Pace, Frances V -- Bonneau, Richard -- Chang, Howard Y -- Acuto, Oreste -- Littman, Dan R -- 1F30CA189514-01/CA/NCI NIH HHS/ -- F30 CA189514/CA/NCI NIH HHS/ -- P50 HG007735/HG/NHGRI NIH HHS/ -- P50-HG007735/HG/NHGRI NIH HHS/ -- R01 AI080885/AI/NIAID NIH HHS/ -- R01 AI121436/AI/NIAID NIH HHS/ -- R01 DK103358/DK/NIDDK NIH HHS/ -- R01 HG004361/HG/NHGRI NIH HHS/ -- R01AI080885/AI/NIAID NIH HHS/ -- R01DK103358/DK/NIDDK NIH HHS/ -- R01HG004361/HG/NHGRI NIH HHS/ -- T32 AI100853/AI/NIAID NIH HHS/ -- T32 CA009161/CA/NCI NIH HHS/ -- Howard Hughes Medical Institute/ -- England -- Nature. 2015 Dec 24;528(7583):517-22. doi: 10.1038/nature16193.

    Structural insights into micro-opioid receptor activation (2015)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2015-08-08
    Description: Activation of the mu-opioid receptor (muOR) is responsible for the efficacy of the most effective analgesics. To shed light on the structural basis for muOR activation, here we report a 2.1 A X-ray crystal structure of the murine muOR bound to the morphinan agonist BU72 and a G protein mimetic camelid antibody fragment. The BU72-stabilized changes in the muOR binding pocket are subtle and differ from those observed for agonist-bound structures of the beta2-adrenergic receptor (beta2AR) and the M2 muscarinic receptor. Comparison with active beta2AR reveals a common rearrangement in the packing of three conserved amino acids in the core of the muOR, and molecular dynamics simulations illustrate how the ligand-binding pocket is conformationally linked to this conserved triad. Additionally, an extensive polar network between the ligand-binding pocket and the cytoplasmic domains appears to play a similar role in signal propagation for all three G-protein-coupled receptors.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4639397/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4639397/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Huang, Weijiao -- Manglik, Aashish -- Venkatakrishnan, A J -- Laeremans, Toon -- Feinberg, Evan N -- Sanborn, Adrian L -- Kato, Hideaki E -- Livingston, Kathryn E -- Thorsen, Thor S -- Kling, Ralf C -- Granier, Sebastien -- Gmeiner, Peter -- Husbands, Stephen M -- Traynor, John R -- Weis, William I -- Steyaert, Jan -- Dror, Ron O -- Kobilka, Brian K -- R01GM083118/GM/NIGMS NIH HHS/ -- R37 DA036246/DA/NIDA NIH HHS/ -- R37DA036246/DA/NIDA NIH HHS/ -- T32 GM008294/GM/NIGMS NIH HHS/ -- England -- Nature. 2015 Aug 20;524(7565):315-21. doi: 10.1038/nature14886.

    The oyster genome reveals stress adaptation and complexity of shell formation (2012)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2012-09-21
    Description: The Pacific oyster Crassostrea gigas belongs to one of the most species-rich but genomically poorly explored phyla, the Mollusca. Here we report the sequencing and assembly of the oyster genome using short reads and a fosmid-pooling strategy, along with transcriptomes of development and stress response and the proteome of the shell. The oyster genome is highly polymorphic and rich in repetitive sequences, with some transposable elements still actively shaping variation. Transcriptome studies reveal an extensive set of genes responding to environmental stress. The expansion of genes coding for heat shock protein 70 and inhibitors of apoptosis is probably central to the oyster's adaptation to sessile life in the highly stressful intertidal zone. Our analyses also show that shell formation in molluscs is more complex than currently understood and involves extensive participation of cells and their exosomes. The oyster genome sequence fills a void in our understanding of the Lophotrochozoa.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Zhang, Guofan -- Fang, Xiaodong -- Guo, Ximing -- Li, Li -- Luo, Ruibang -- Xu, Fei -- Yang, Pengcheng -- Zhang, Linlin -- Wang, Xiaotong -- Qi, Haigang -- Xiong, Zhiqiang -- Que, Huayong -- Xie, Yinlong -- Holland, Peter W H -- Paps, Jordi -- Zhu, Yabing -- Wu, Fucun -- Chen, Yuanxin -- Wang, Jiafeng -- Peng, Chunfang -- Meng, Jie -- Yang, Lan -- Liu, Jun -- Wen, Bo -- Zhang, Na -- Huang, Zhiyong -- Zhu, Qihui -- Feng, Yue -- Mount, Andrew -- Hedgecock, Dennis -- Xu, Zhe -- Liu, Yunjie -- Domazet-Loso, Tomislav -- Du, Yishuai -- Sun, Xiaoqing -- Zhang, Shoudu -- Liu, Binghang -- Cheng, Peizhou -- Jiang, Xuanting -- Li, Juan -- Fan, Dingding -- Wang, Wei -- Fu, Wenjing -- Wang, Tong -- Wang, Bo -- Zhang, Jibiao -- Peng, Zhiyu -- Li, Yingxiang -- Li, Na -- Wang, Jinpeng -- Chen, Maoshan -- He, Yan -- Tan, Fengji -- Song, Xiaorui -- Zheng, Qiumei -- Huang, Ronglian -- Yang, Hailong -- Du, Xuedi -- Chen, Li -- Yang, Mei -- Gaffney, Patrick M -- Wang, Shan -- Luo, Longhai -- She, Zhicai -- Ming, Yao -- Huang, Wen -- Zhang, Shu -- Huang, Baoyu -- Zhang, Yong -- Qu, Tao -- Ni, Peixiang -- Miao, Guoying -- Wang, Junyi -- Wang, Qiang -- Steinberg, Christian E W -- Wang, Haiyan -- Li, Ning -- Qian, Lumin -- Zhang, Guojie -- Li, Yingrui -- Yang, Huanming -- Liu, Xiao -- Wang, Jian -- Yin, Ye -- Wang, Jun -- 268513/European Research Council/International -- England -- Nature. 2012 Oct 4;490(7418):49-54. doi: 10.1038/nature11413.

    Social reward requires coordinated activity of nucleus accumbens oxytocin and serotonin (2013)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2013-09-13
    Description: Social behaviours in species as diverse as honey bees and humans promote group survival but often come at some cost to the individual. Although reinforcement of adaptive social interactions is ostensibly required for the evolutionary persistence of these behaviours, the neural mechanisms by which social reward is encoded by the brain are largely unknown. Here we demonstrate that in mice oxytocin acts as a social reinforcement signal within the nucleus accumbens core, where it elicits a presynaptically expressed long-term depression of excitatory synaptic transmission in medium spiny neurons. Although the nucleus accumbens receives oxytocin-receptor-containing inputs from several brain regions, genetic deletion of these receptors specifically from dorsal raphe nucleus, which provides serotonergic (5-hydroxytryptamine; 5-HT) innervation to the nucleus accumbens, abolishes the reinforcing properties of social interaction. Furthermore, oxytocin-induced synaptic plasticity requires activation of nucleus accumbens 5-HT1B receptors, the blockade of which prevents social reward. These results demonstrate that the rewarding properties of social interaction in mice require the coordinated activity of oxytocin and 5-HT in the nucleus accumbens, a mechanistic insight with implications for understanding the pathogenesis of social dysfunction in neuropsychiatric disorders such as autism.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4091761/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4091761/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Dolen, Gul -- Darvishzadeh, Ayeh -- Huang, Kee Wui -- Malenka, Robert C -- NS069375/NS/NINDS NIH HHS/ -- P01 DA008227/DA/NIDA NIH HHS/ -- P30 NS069375/NS/NINDS NIH HHS/ -- R21 DA032955/DA/NIDA NIH HHS/ -- England -- Nature. 2013 Sep 12;501(7466):179-84. doi: 10.1038/nature12518.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Nancy Pritzker Laboratory, Department of Psychiatry and Behavioral Sciences, Stanford University School of Medicine, 265 Campus Drive, Stanford, California 94305, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/24025838" target="_blank"〉PubMed〈/a〉
