    Description: The mechanisms controlling axon guidance are of fundamental importance in understanding brain development. Growing corticospinal and somatosensory axons cross the midline in the medulla to reach their targets and thus form the basis of contralateral motor control and sensory input. The motor and sensory projections appeared uncrossed in patients with horizontal gaze palsy with progressive scoliosis (HGPPS). In patients affected with HGPPS, we identified mutations in the ROBO3 gene, which shares homology with roundabout genes important in axon guidance in developing Drosophila, zebrafish, and mouse. Like its murine homolog Rig1/Robo3, but unlike other Robo proteins, ROBO3 is required for hindbrain axon midline crossing.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC1618874/" 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/PMC1618874/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Jen, Joanna C -- Chan, Wai-Man -- Bosley, Thomas M -- Wan, Jijun -- Carr, Janai R -- Rub, Udo -- Shattuck, David -- Salamon, Georges -- Kudo, Lili C -- Ou, Jing -- Lin, Doris D M -- Salih, Mustafa A M -- Kansu, Tulay -- Al Dhalaan, Hesham -- Al Zayed, Zayed -- MacDonald, David B -- Stigsby, Bent -- Plaitakis, Andreas -- Dretakis, Emmanuel K -- Gottlob, Irene -- Pieh, Christina -- Traboulsi, Elias I -- Wang, Qing -- Wang, Lejin -- Andrews, Caroline -- Yamada, Koki -- Demer, Joseph L -- Karim, Shaheen -- Alger, Jeffry R -- Geschwind, Daniel H -- Deller, Thomas -- Sicotte, Nancy L -- Nelson, Stanley F -- Baloh, Robert W -- Engle, Elizabeth C -- DC00162/DC/NIDCD NIH HHS/ -- DC05524/DC/NIDCD NIH HHS/ -- EY12498/EY/NEI NIH HHS/ -- EY13583/EY/NEI NIH HHS/ -- EY15298/EY/NEI NIH HHS/ -- EY15311/EY/NEI NIH HHS/ -- MH60233/MH/NIMH NIH HHS/ -- P30 HD 18655/HD/NICHD NIH HHS/ -- R01 EY008313/EY/NEI NIH HHS/ -- R01 EY008313-14/EY/NEI NIH HHS/ -- R01 HL066251/HL/NHLBI NIH HHS/ -- New York, N.Y. -- Science. 2004 Jun 4;304(5676):1509-13.

    Description: The 1918 influenza pandemic resulted in about 20 million deaths. This enormous impact, coupled with renewed interest in emerging infections, makes characterization of the virus involved a priority. Receptor binding, the initial event in virus infection, is a major determinant of virus transmissibility that, for influenza viruses, is mediated by the hemagglutinin (HA) membrane glycoprotein. We have determined the crystal structures of the HA from the 1918 virus and two closely related HAs in complex with receptor analogs. They explain how the 1918 HA, while retaining receptor binding site amino acids characteristic of an avian precursor HA, is able to bind human receptors and how, as a consequence, the virus was able to spread in the human population.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Gamblin, S J -- Haire, L F -- Russell, R J -- Stevens, D J -- Xiao, B -- Ha, Y -- Vasisht, N -- Steinhauer, D A -- Daniels, R S -- Elliot, A -- Wiley, D C -- Skehel, J J -- AI-13654/AI/NIAID NIH HHS/ -- New York, N.Y. -- Science. 2004 Mar 19;303(5665):1838-42.

    Description: Parkinson's disease (PD) is a neurodegenerative disorder characterized by degeneration of dopaminergic neurons in the substantia nigra. We previously mapped a locus for a rare familial form of PD to chromosome 1p36 (PARK6). Here we show that mutations in PINK1 (PTEN-induced kinase 1) are associated with PARK6. We have identified two homozygous mutations affecting the PINK1 kinase domain in three consanguineous PARK6 families: a truncating nonsense mutation and a missense mutation at a highly conserved amino acid. Cell culture studies suggest that PINK1 is mitochondrially located and may exert a protective effect on the cell that is abrogated by the mutations, resulting in increased susceptibility to cellular stress. These data provide a direct molecular link between mitochondria and the pathogenesis of PD.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Valente, Enza Maria -- Abou-Sleiman, Patrick M -- Caputo, Viviana -- Muqit, Miratul M K -- Harvey, Kirsten -- Gispert, Suzana -- Ali, Zeeshan -- Del Turco, Domenico -- Bentivoglio, Anna Rita -- Healy, Daniel G -- Albanese, Alberto -- Nussbaum, Robert -- Gonzalez-Maldonado, Rafael -- Deller, Thomas -- Salvi, Sergio -- Cortelli, Pietro -- Gilks, William P -- Latchman, David S -- Harvey, Robert J -- Dallapiccola, Bruno -- Auburger, Georg -- Wood, Nicholas W -- G-4029/Parkinson's UK/United Kingdom -- GGP02089/Telethon/Italy -- New York, N.Y. -- Science. 2004 May 21;304(5674):1158-60.

    Description: The structure of the general transcription factor IIB (TFIIB) in a complex with RNA polymerase II reveals three features crucial for transcription initiation: an N-terminal zinc ribbon domain of TFIIB that contacts the "dock" domain of the polymerase, near the path of RNA exit from a transcribing enzyme; a "finger" domain of TFIIB that is inserted into the polymerase active center; and a C-terminal domain, whose interaction with both the polymerase and with a TATA box-binding protein (TBP)-promoter DNA complex orients the DNA for unwinding and transcription. TFIIB stabilizes an early initiation complex, containing an incomplete RNA-DNA hybrid region. It may interact with the template strand, which sets the location of the transcription start site, and may interfere with RNA exit, which leads to abortive initiation or promoter escape. The trajectory of promoter DNA determined by the C-terminal domain of TFIIB traverses sites of interaction with TFIIE, TFIIF, and TFIIH, serving to define their roles in the transcription initiation process.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Bushnell, David A -- Westover, Kenneth D -- Davis, Ralph E -- Kornberg, Roger D -- AI21144/AI/NIAID NIH HHS/ -- GM49985/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2004 Feb 13;303(5660):983-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Structural Biology, Stanford University School of Medicine, Stanford, CA 94305-5126, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/14963322" target="_blank"〉PubMed〈/a〉

    Description: Mitochondrial dysfunction is a hallmark of beta-amyloid (Abeta)-induced neuronal toxicity in Alzheimer's disease (AD). Here, we demonstrate that Abeta-binding alcohol dehydrogenase (ABAD) is a direct molecular link from Abeta to mitochondrial toxicity. Abeta interacts with ABAD in the mitochondria of AD patients and transgenic mice. The crystal structure of Abeta-bound ABAD shows substantial deformation of the active site that prevents nicotinamide adenine dinucleotide (NAD) binding. An ABAD peptide specifically inhibits ABAD-Abeta interaction and suppresses Abeta-induced apoptosis and free-radical generation in neurons. Transgenic mice overexpressing ABAD in an Abeta-rich environment manifest exaggerated neuronal oxidative stress and impaired memory. These data suggest that the ABAD-Abeta interaction may be a therapeutic target in AD.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lustbader, Joyce W -- Cirilli, Maurizio -- Lin, Chang -- Xu, Hong Wei -- Takuma, Kazuhiro -- Wang, Ning -- Caspersen, Casper -- Chen, Xi -- Pollak, Susan -- Chaney, Michael -- Trinchese, Fabrizio -- Liu, Shumin -- Gunn-Moore, Frank -- Lue, Lih-Fen -- Walker, Douglas G -- Kuppusamy, Periannan -- Zewier, Zay L -- Arancio, Ottavio -- Stern, David -- Yan, Shirley ShiDu -- Wu, Hao -- 1K07AG00959/AG/NIA NIH HHS/ -- AG16736/AG/NIA NIH HHS/ -- AG17490/AG/NIA NIH HHS/ -- NS42855/NS/NINDS NIH HHS/ -- P50AG08702/AG/NIA NIH HHS/ -- New York, N.Y. -- Science. 2004 Apr 16;304(5669):448-52.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Center for Reproductive Sciences and Department of Obstetrics and Gynecology, College of Physicians and Surgeons, Columbia University, 630 West 168th Street, New York, NY 10032, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/15087549" target="_blank"〉PubMed〈/a〉

    Description: Plants under oxidative stress suffer from damages that have been interpreted as unavoidable consequences of injuries inflicted upon plants by toxic levels of reactive oxygen species (ROS). However, this paradigm needs to be modified. Inactivation of a single gene, EXECUTER1, is sufficient to abrogate stress responses of Arabidopsis thaliana caused by the release of singlet oxygen: External conditions under which these stress responses are observed and the amounts of ROS that accumulate in plants exposed to these environmental conditions do not directly cause damages. Instead, seedling lethality and growth inhibition of mature plants result from genetic programs that are activated after the release of singlet oxygen has been perceived by the plant.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Wagner, Daniela -- Przybyla, Dominika -- Op den Camp, Roel -- Kim, Chanhong -- Landgraf, Frank -- Lee, Keun Pyo -- Wursch, Marco -- Laloi, Christophe -- Nater, Mena -- Hideg, Eva -- Apel, Klaus -- New York, N.Y. -- Science. 2004 Nov 12;306(5699):1183-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Institute of Plant Sciences, Plant Genetics, Swiss Federal Institute of Technology (ETH), CH-8092 Zurich, Switzerland.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/15539603" target="_blank"〉PubMed〈/a〉

    Description: The herbicide glyphosate is effectively detoxified by N-acetylation. We screened a collection of microbial isolates and discovered enzymes exhibiting glyphosate N-acetyltransferase (GAT) activity. Kinetic properties of the discovered enzymes were insufficient to confer glyphosate tolerance to transgenic organisms. Eleven iterations of DNA shuffling improved enzyme efficiency by nearly four orders of magnitude from 0.87 mM-1 min-1 to 8320 mM-1 min-1. From the fifth iteration and beyond, GAT enzymes conferred increasing glyphosate tolerance to Escherichia coli, Arabidopsis, tobacco, and maize. Glyphosate acetylation provides an alternative strategy for supporting glyphosate use on crops.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Castle, Linda A -- Siehl, Daniel L -- Gorton, Rebecca -- Patten, Phillip A -- Chen, Yong Hong -- Bertain, Sean -- Cho, Hyeon-Je -- Duck, Nicholas -- Wong, James -- Liu, Donglong -- Lassner, Michael W -- New York, N.Y. -- Science. 2004 May 21;304(5674):1151-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Verdia, Inc.

    Description: A genetic interaction network containing approximately 1000 genes and approximately 4000 interactions was mapped by crossing mutations in 132 different query genes into a set of approximately 4700 viable gene yeast deletion mutants and scoring the double mutant progeny for fitness defects. Network connectivity was predictive of function because interactions often occurred among functionally related genes, and similar patterns of interactions tended to identify components of the same pathway. The genetic network exhibited dense local neighborhoods; therefore, the position of a gene on a partially mapped network is predictive of other genetic interactions. Because digenic interactions are common in yeast, similar networks may underlie the complex genetics associated with inherited phenotypes in other organisms.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Tong, Amy Hin Yan -- Lesage, Guillaume -- Bader, Gary D -- Ding, Huiming -- Xu, Hong -- Xin, Xiaofeng -- Young, James -- Berriz, Gabriel F -- Brost, Renee L -- Chang, Michael -- Chen, YiQun -- Cheng, Xin -- Chua, Gordon -- Friesen, Helena -- Goldberg, Debra S -- Haynes, Jennifer -- Humphries, Christine -- He, Grace -- Hussein, Shamiza -- Ke, Lizhu -- Krogan, Nevan -- Li, Zhijian -- Levinson, Joshua N -- Lu, Hong -- Menard, Patrice -- Munyana, Christella -- Parsons, Ainslie B -- Ryan, Owen -- Tonikian, Raffi -- Roberts, Tania -- Sdicu, Anne-Marie -- Shapiro, Jesse -- Sheikh, Bilal -- Suter, Bernhard -- Wong, Sharyl L -- Zhang, Lan V -- Zhu, Hongwei -- Burd, Christopher G -- Munro, Sean -- Sander, Chris -- Rine, Jasper -- Greenblatt, Jack -- Peter, Matthias -- Bretscher, Anthony -- Bell, Graham -- Roth, Frederick P -- Brown, Grant W -- Andrews, Brenda -- Bussey, Howard -- Boone, Charles -- GM39066/GM/NIGMS NIH HHS/ -- GM61221/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2004 Feb 6;303(5659):808-13.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Banting and Best Department of Medical Research, University of Toronto, Toronto, ON, Canada M5G 1L6.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/14764870" target="_blank"〉PubMed〈/a〉

    Description: Inherited defects in signaling pathways downstream of the insulin receptor have long been suggested to contribute to human type 2 diabetes mellitus. Here we describe a mutation in the gene encoding the protein kinase AKT2/PKBbeta in a family that shows autosomal dominant inheritance of severe insulin resistance and diabetes mellitus. Expression of the mutant kinase in cultured cells disrupted insulin signaling to metabolic end points and inhibited the function of coexpressed, wild-type AKT. These findings demonstrate the central importance of AKT signaling to insulin sensitivity in humans.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2258004/" 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/PMC2258004/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉George, Stella -- Rochford, Justin J -- Wolfrum, Christian -- Gray, Sarah L -- Schinner, Sven -- Wilson, Jenny C -- Soos, Maria A -- Murgatroyd, Peter R -- Williams, Rachel M -- Acerini, Carlo L -- Dunger, David B -- Barford, David -- Umpleby, A Margot -- Wareham, Nicholas J -- Davies, Huw Alban -- Schafer, Alan J -- Stoffel, Markus -- O'Rahilly, Stephen -- Barroso, Ines -- 078986/Wellcome Trust/United Kingdom -- New York, N.Y. -- Science. 2004 May 28;304(5675):1325-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Clinical Biochemistry, University of Cambridge, Addenbrooke's Hospital, Hills Road, Cambridge CB2 2QQ, UK.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/15166380" target="_blank"〉PubMed〈/a〉

    Description: Arabidopsis thaliana De-etiolated-1 (AtDET1) is a highly conserved protein, with orthologs in vertebrate and invertebrate organisms. AtDET1 negatively regulates photomorphogenesis, but its biochemical mechanism and function in other species are unknown. We report that human DET1 (hDET1) promotes ubiquitination and degradation of the proto-oncogenic transcription factor c-Jun by assembling a multisubunit ubiquitin ligase containing DNA Damage Binding Protein-1 (DDB1), cullin 4A (CUL4A), Regulator of Cullins-1 (ROC1), and constitutively photomorphogenic-1. Ablation of any subunit by RNA interference stabilized c-Jun and increased c-Jun-activated transcription. These findings characterize a c-Jun ubiquitin ligase and define a specific function for hDET1 in mammalian cells.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Wertz, Ingrid E -- O'Rourke, Karen M -- Zhang, Zemin -- Dornan, David -- Arnott, David -- Deshaies, Raymond J -- Dixit, Vishva M -- GM065997/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2004 Feb 27;303(5662):1371-4.
