    Cartilage acidic protein-1B (LOTUS), an endogenous Nogo receptor antagonist for axon tract formation (2011)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 2011-08-06
    Beschreibung: Neural circuitry formation depends on the molecular control of axonal projection during development. By screening with fluorophore-assisted light inactivation in the developing mouse brain, we identified cartilage acidic protein-1B as a key molecule for lateral olfactory tract (LOT) formation and named it LOT usher substance (LOTUS). We further identified Nogo receptor-1 (NgR1) as a LOTUS-binding protein. NgR1 is a receptor of myelin-derived axon growth inhibitors, such as Nogo, which prevent neural regeneration in the adult. LOTUS suppressed Nogo-NgR1 binding and Nogo-induced growth cone collapse. A defasciculated LOT was present in lotus-deficient mice but not in mice lacking both lotus- and ngr1. These findings suggest that endogenous antagonism of NgR1 by LOTUS is crucial for normal LOT formation.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3244695/" 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/PMC3244695/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Sato, Yasufumi -- Iketani, Masumi -- Kurihara, Yuji -- Yamaguchi, Megumi -- Yamashita, Naoya -- Nakamura, Fumio -- Arie, Yuko -- Kawasaki, Takahiko -- Hirata, Tatsumi -- Abe, Takaya -- Kiyonari, Hiroshi -- Strittmatter, Stephen M -- Goshima, Yoshio -- Takei, Kohtaro -- R37 NS033020/NS/NINDS NIH HHS/ -- R37 NS033020-19/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 2011 Aug 5;333(6043):769-73. doi: 10.1126/science.1204144.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Molecular Pharmacology and Neurobiology, Yokohama City University Graduate School of Medicine, Yokohama 236-0004, Japan.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/21817055" target="_blank"〉PubMed〈/a〉

    Long noncoding RNA as modular scaffold of histone modification complexes (2010)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 2010-07-10
    Beschreibung: Long intergenic noncoding RNAs (lincRNAs) regulate chromatin states and epigenetic inheritance. Here, we show that the lincRNA HOTAIR serves as a scaffold for at least two distinct histone modification complexes. A 5' domain of HOTAIR binds polycomb repressive complex 2 (PRC2), whereas a 3' domain of HOTAIR binds the LSD1/CoREST/REST complex. The ability to tether two distinct complexes enables RNA-mediated assembly of PRC2 and LSD1 and coordinates targeting of PRC2 and LSD1 to chromatin for coupled histone H3 lysine 27 methylation and lysine 4 demethylation. Our results suggest that lincRNAs may serve as scaffolds by providing binding surfaces to assemble select histone modification enzymes, thereby specifying the pattern of histone modifications on target genes.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2967777/" 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/PMC2967777/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Tsai, Miao-Chih -- Manor, Ohad -- Wan, Yue -- Mosammaparast, Nima -- Wang, Jordon K -- Lan, Fei -- Shi, Yang -- Segal, Eran -- Chang, Howard Y -- R01 CA118750/CA/NCI NIH HHS/ -- R01 CA119176/CA/NCI NIH HHS/ -- R01 CA119176-05/CA/NCI NIH HHS/ -- R01-CA118487/CA/NCI NIH HHS/ -- R01-HG004361/HG/NHGRI NIH HHS/ -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2010 Aug 6;329(5992):689-93. doi: 10.1126/science.1192002.

    Two histone marks establish the inner centromere and chromosome bi-orientation (2010)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 2010-10-12
    Beschreibung: For proper partitioning of chromosomes in mitosis, the chromosomal passenger complex (CPC) including Aurora B and survivin must be localized at the center of paired kinetochores, at the site called the inner centromere. It is largely unknown what defines the inner centromere and how the CPC is targeted to this site. Here, we show that the phosphorylation of histone H3-threonine 3 (H3-pT3) mediated by Haspin cooperates with Bub1-mediated histone 2A-serine 121 (H2A-S121) phosphorylation in targeting the CPC to the inner centromere in fission yeast and human cells. H3-pT3 promotes nucleosome binding of survivin, whereas phosphorylated H2A-S121 facilitates the binding of shugoshin, the centromeric CPC adaptor. Haspin colocalizes with cohesin by associating with Pds5, whereas Bub1 localizes at kinetochores. Thus, the inner centromere is defined by intersection of two histone kinases.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Yamagishi, Yuya -- Honda, Takashi -- Tanno, Yuji -- Watanabe, Yoshinori -- New York, N.Y. -- Science. 2010 Oct 8;330(6001):239-43. doi: 10.1126/science.1194498.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Laboratory of Chromosome Dynamics, Institute of Molecular and Cellular Biosciences, University of Tokyo, Yayoi, Tokyo 113-0032, Japan.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/20929775" target="_blank"〉PubMed〈/a〉

    Siah regulation of Pard3A controls neuronal cell adhesion during germinal zone exit (2010)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 2010-11-27
    Beschreibung: The brain's circuitry is established by directed migration and synaptogenesis of neurons during development. Although neurons mature and migrate in specific patterns, little is known about how neurons exit their germinal zone niche. We found that cerebellar granule neuron germinal zone exit is regulated by proteasomal degradation of Pard3A by the Seven in Absentia homolog (Siah) E3 ubiquitin ligase. Pard3A gain of function and Siah loss of function induce precocious radial migration. Time-lapse imaging using a probe to measure neuronal cell contact reveals that Pard3A promotes adhesive interactions needed for germinal zone exit by recruiting the epithelial tight junction adhesion molecule C to the neuronal cell surface. Our findings define a Siah-Pard3A signaling pathway that controls adhesion-dependent exit of neuronal progenitors or immature neurons from a germinal zone niche.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3065828/" 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/PMC3065828/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Famulski, Jakub K -- Trivedi, Niraj -- Howell, Danielle -- Yang, Yuan -- Tong, Yiai -- Gilbertson, Richard -- Solecki, David J -- P01 CA096832/CA/NCI NIH HHS/ -- P01 CA096832-07/CA/NCI NIH HHS/ -- P30 CA021765/CA/NCI NIH HHS/ -- P30 CA021765-33/CA/NCI NIH HHS/ -- R01 CA129541/CA/NCI NIH HHS/ -- R01 CA129541-04/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 2010 Dec 24;330(6012):1834-8. doi: 10.1126/science.1198480.

    Structural basis for tail-anchored membrane protein biogenesis by the Get3-receptor complex (2011)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 2011-07-02
    Beschreibung: Tail-anchored (TA) proteins are involved in cellular processes including trafficking, degradation, and apoptosis. They contain a C-terminal membrane anchor and are posttranslationally delivered to the endoplasmic reticulum (ER) membrane by the Get3 adenosine triphosphatase interacting with the hetero-oligomeric Get1/2 receptor. We have determined crystal structures of Get3 in complex with the cytosolic domains of Get1 and Get2 in different functional states at 3.0, 3.2, and 4.6 angstrom resolution. The structural data, together with biochemical experiments, show that Get1 and Get2 use adjacent, partially overlapping binding sites and that both can bind simultaneously to Get3. Docking to the Get1/2 complex allows for conformational changes in Get3 that are required for TA protein insertion. These data suggest a molecular mechanism for nucleotide-regulated delivery of TA proteins.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3601824/" 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/PMC3601824/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Stefer, Susanne -- Reitz, Simon -- Wang, Fei -- Wild, Klemens -- Pang, Yin-Yuin -- Schwarz, Daniel -- Bomke, Jorg -- Hein, Christopher -- Lohr, Frank -- Bernhard, Frank -- Denic, Vladimir -- Dotsch, Volker -- Sinning, Irmgard -- R01 GM099943/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2011 Aug 5;333(6043):758-62. doi: 10.1126/science.1207125.

    Crystal structure of the heterodimeric CLOCK:BMAL1 transcriptional activator complex (2012)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 2012-06-02
    Beschreibung: The circadian clock in mammals is driven by an autoregulatory transcriptional feedback mechanism that takes approximately 24 hours to complete. A key component of this mechanism is a heterodimeric transcriptional activator consisting of two basic helix-loop-helix PER-ARNT-SIM (bHLH-PAS) domain protein subunits, CLOCK and BMAL1. Here, we report the crystal structure of a complex containing the mouse CLOCK:BMAL1 bHLH-PAS domains at 2.3 A resolution. The structure reveals an unusual asymmetric heterodimer with the three domains in each of the two subunits--bHLH, PAS-A, and PAS-B--tightly intertwined and involved in dimerization interactions, resulting in three distinct protein interfaces. Mutations that perturb the observed heterodimer interfaces affect the stability and activity of the CLOCK:BMAL1 complex as well as the periodicity of the circadian oscillator. The structure of the CLOCK:BMAL1 complex is a starting point for understanding at an atomic level the mechanism driving the mammalian circadian clock.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3694778/" 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/PMC3694778/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Huang, Nian -- Chelliah, Yogarany -- Shan, Yongli -- Taylor, Clinton A -- Yoo, Seung-Hee -- Partch, Carrie -- Green, Carla B -- Zhang, Hong -- Takahashi, Joseph S -- R01 GM081875/GM/NIGMS NIH HHS/ -- R01 GM090247/GM/NIGMS NIH HHS/ -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2012 Jul 13;337(6091):189-94. doi: 10.1126/science.1222804.

    Probing allostery through DNA (2013)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 2013-02-16
    Beschreibung: Allostery is well documented for proteins but less recognized for DNA-protein interactions. Here, we report that specific binding of a protein on DNA is substantially stabilized or destabilized by another protein bound nearby. The ternary complex's free energy oscillates as a function of the separation between the two proteins with a periodicity of ~10 base pairs, the helical pitch of B-form DNA, and a decay length of ~15 base pairs. The binding affinity of a protein near a DNA hairpin is similarly dependent on their separation, which-together with molecular dynamics simulations-suggests that deformation of the double-helical structure is the origin of DNA allostery. The physiological relevance of this phenomenon is illustrated by its effect on gene expression in live bacteria and on a transcription factor's affinity near nucleosomes.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3586787/" 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/PMC3586787/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kim, Sangjin -- Brostromer, Erik -- Xing, Dong -- Jin, Jianshi -- Chong, Shasha -- Ge, Hao -- Wang, Siyuan -- Gu, Chan -- Yang, Lijiang -- Gao, Yi Qin -- Su, Xiao-dong -- Sun, Yujie -- Xie, X Sunney -- DP1 OD000277/OD/NIH HHS/ -- New York, N.Y. -- Science. 2013 Feb 15;339(6121):816-9. doi: 10.1126/science.1229223.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Chemistry and Chemical Biology, Harvard University, Cambridge, MA 02138, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/23413354" target="_blank"〉PubMed〈/a〉

    Influenza A virus uses the aggresome processing machinery for host cell entry (2014)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 2014-10-25
    Beschreibung: During cell entry, capsids of incoming influenza A viruses (IAVs) must be uncoated before viral ribonucleoproteins (vRNPs) can enter the nucleus for replication. After hemagglutinin-mediated membrane fusion in late endocytic vacuoles, the vRNPs and the matrix proteins dissociate from each other and disperse within the cytosol. Here, we found that for capsid disassembly, IAV takes advantage of the host cell's aggresome formation and disassembly machinery. The capsids mimicked misfolded protein aggregates by carrying unanchored ubiquitin chains that activated a histone deacetylase 6 (HDAC6)-dependent pathway. The ubiquitin-binding domain was essential for recruitment of HDAC6 to viral fusion sites and for efficient uncoating and infection. That other components of the aggresome processing machinery, including dynein, dynactin, and myosin II, were also required suggested that physical forces generated by microtubule- and actin-associated motors are essential for IAV entry.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Banerjee, Indranil -- Miyake, Yasuyuki -- Nobs, Samuel Philip -- Schneider, Christoph -- Horvath, Peter -- Kopf, Manfred -- Matthias, Patrick -- Helenius, Ari -- Yamauchi, Yohei -- New York, N.Y. -- Science. 2014 Oct 24;346(6208):473-7. doi: 10.1126/science.1257037.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Institute of Biochemistry, Eidgenossische Technische Hochschule (ETH) Zurich, Switzerland. ; Epigenetics, Friedrich Miescher Institute for Biomedical Research, Basel, Switzerland. ; Institute of Molecular Health Sciences, ETH Zurich, Switzerland. ; Synthetic and Systems Biology Unit, Biological Research Center, Szeged, Hungary. ; Epigenetics, Friedrich Miescher Institute for Biomedical Research, Basel, Switzerland.

    Chloroplasts divide by contraction of a bundle of nanofilaments consisting of polyglucan (2010)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 2010-08-21
    Beschreibung: In chloroplast division, the plastid-dividing (PD) ring is a main structure of the PD machinery and is a universal structure in the plant kingdom. However, the components and formation of the PD ring have been enigmatic. By proteomic analysis of PD machineries isolated from Cyanidioschyzon merolae, we identified the glycosyltransferase protein plastid-dividing ring 1 (PDR1), which constructs the PD ring and is widely conserved from red alga to land plants. Electron microscopy showed that the PDR1 protein forms a ring with carbohydrates at the chloroplast-division site. Fluorometric saccharide ingredient analysis of purified PD ring filaments showed that only glucose was included, and down-regulation of PDR1 impaired chloroplast division. Thus, the chloroplasts are divided by the PD ring, which is a bundle of PDR1-mediated polyglucan filaments.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Yoshida, Yamato -- Kuroiwa, Haruko -- Misumi, Osami -- Yoshida, Masaki -- Ohnuma, Mio -- Fujiwara, Takayuki -- Yagisawa, Fumi -- Hirooka, Shunsuke -- Imoto, Yuuta -- Matsushita, Kazunobu -- Kawano, Shigeyuki -- Kuroiwa, Tsuneyoshi -- New York, N.Y. -- Science. 2010 Aug 20;329(5994):949-53. doi: 10.1126/science.1190791.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Laboratory of Cell Biology, Department of Life Science, College of Science, Research Information Center for Extremophile, Rikkyo University, Toshima, Tokyo 171-8501, Japan.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/20724635" target="_blank"〉PubMed〈/a〉

    Beschreibung: Abscisic acid (ABA) is an essential hormone for plants to survive environmental stresses. At the center of the ABA signaling network is a subfamily of type 2C protein phosphatases (PP2Cs), which form exclusive interactions with ABA receptors and subfamily 2 Snfl-related kinase (SnRK2s). Here, we report a SnRK2-PP2C complex structure, which reveals marked similarity in PP2C recognition by SnRK2 and ABA receptors. In the complex, the kinase activation loop docks into the active site of PP2C, while the conserved ABA-sensing tryptophan of PP2C inserts into the kinase catalytic cleft, thus mimicking receptor-PP2C interactions. These structural results provide a simple mechanism that directly couples ABA binding to SnRK2 kinase activation and highlight a new paradigm of kinase-phosphatase regulation through mutual packing of their catalytic sites.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3584687/" 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/PMC3584687/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Soon, Fen-Fen -- Ng, Ley-Moy -- Zhou, X Edward -- West, Graham M -- Kovach, Amanda -- Tan, M H Eileen -- Suino-Powell, Kelly M -- He, Yuanzheng -- Xu, Yong -- Chalmers, Michael J -- Brunzelle, Joseph S -- Zhang, Huiming -- Yang, Huaiyu -- Jiang, Hualiang -- Li, Jun -- Yong, Eu-Leong -- Cutler, Sean -- Zhu, Jian-Kang -- Griffin, Patrick R -- Melcher, Karsten -- Xu, H Eric -- GM084041/GM/NIGMS NIH HHS/ -- R01 GM059138/GM/NIGMS NIH HHS/ -- S10 RR027270/RR/NCRR NIH HHS/ -- New York, N.Y. -- Science. 2012 Jan 6;335(6064):85-8. doi: 10.1126/science.1215106.
