    Gene expression during the life cycle of Drosophila melanogaster (2002)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2002-09-28
    Description: Molecular genetic studies of Drosophila melanogaster have led to profound advances in understanding the regulation of development. Here we report gene expression patterns for nearly one-third of all Drosophila genes during a complete time course of development. Mutations that eliminate eye or germline tissue were used to further analyze tissue-specific gene expression programs. These studies define major characteristics of the transcriptional programs that underlie the life cycle, compare development in males and females, and show that large-scale gene expression data collected from whole animals can be used to identify genes expressed in particular tissues and organs or genes involved in specific biological and biochemical processes.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Arbeitman, Michelle N -- Furlong, Eileen E M -- Imam, Farhad -- Johnson, Eric -- Null, Brian H -- Baker, Bruce S -- Krasnow, Mark A -- Scott, Matthew P -- Davis, Ronald W -- White, Kevin P -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2002 Sep 27;297(5590):2270-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biological Sciences, Stanford University, Stanford, CA 94305, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/12351791" target="_blank"〉PubMed〈/a〉

    Linkage of plasma Abeta42 to a quantitative locus on chromosome 10 in late-onset Alzheimer's disease pedigrees (2000)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2000-12-23
    Description: Plasma Abeta42 (amyloid beta42 peptide) is invariably elevated in early-onset familial Alzheimer's disease (AD), and it is also increased in the first-degree relatives of patients with typical late-onset AD (LOAD). To detect LOAD loci that increase Abeta42, we used plasma Abeta42 as a surrogate trait and performed linkage analysis on extended AD pedigrees identified through a LOAD patient with extremely high plasma Abeta. Here, we report linkage to chromosome 10 with a maximal lod score of 3.93 at 81 centimorgans close to D10S1225. Remarkably, linkage to the same region was obtained independently in a genome-wide screen of LOAD sibling pairs. These results provide strong evidence for a novel LOAD locus on chromosome 10 that acts to increase Abeta.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Ertekin-Taner, N -- Graff-Radford, N -- Younkin, L H -- Eckman, C -- Baker, M -- Adamson, J -- Ronald, J -- Blangero, J -- Hutton, M -- Younkin, S G -- AG06656/AG/NIA NIH HHS/ -- MH59490/MH/NIMH NIH HHS/ -- P50 AG16574/AG/NIA NIH HHS/ -- New York, N.Y. -- Science. 2000 Dec 22;290(5500):2303-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Mayo Clinic Jacksonville, Jacksonville, FL 32224, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/11125143" target="_blank"〉PubMed〈/a〉

    Structure of a beta1-adrenergic G-protein-coupled receptor (2008)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2008-07-03
    Description: G-protein-coupled receptors have a major role in transmembrane signalling in most eukaryotes and many are important drug targets. Here we report the 2.7 A resolution crystal structure of a beta(1)-adrenergic receptor in complex with the high-affinity antagonist cyanopindolol. The modified turkey (Meleagris gallopavo) receptor was selected to be in its antagonist conformation and its thermostability improved by earlier limited mutagenesis. The ligand-binding pocket comprises 15 side chains from amino acid residues in 4 transmembrane alpha-helices and extracellular loop 2. This loop defines the entrance of the ligand-binding pocket and is stabilized by two disulphide bonds and a sodium ion. Binding of cyanopindolol to the beta(1)-adrenergic receptor and binding of carazolol to the beta(2)-adrenergic receptor involve similar interactions. A short well-defined helix in cytoplasmic loop 2, not observed in either rhodopsin or the beta(2)-adrenergic receptor, directly interacts by means of a tyrosine with the highly conserved DRY motif at the end of helix 3 that is essential for receptor activation.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2923055/" 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/PMC2923055/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Warne, Tony -- Serrano-Vega, Maria J -- Baker, Jillian G -- Moukhametzianov, Rouslan -- Edwards, Patricia C -- Henderson, Richard -- Leslie, Andrew G W -- Tate, Christopher G -- Schertler, Gebhard F X -- MC_U105178937/Medical Research Council/United Kingdom -- MC_U105184322/Medical Research Council/United Kingdom -- MC_U105184325/Medical Research Council/United Kingdom -- MC_U105197215/Medical Research Council/United Kingdom -- U.1051.04.020(78937)/Medical Research Council/United Kingdom -- Wellcome Trust/United Kingdom -- England -- Nature. 2008 Jul 24;454(7203):486-91. doi: 10.1038/nature07101.

    Kemp elimination catalysts by computational enzyme design (2008)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2008-03-21
    Description: The design of new enzymes for reactions not catalysed by naturally occurring biocatalysts is a challenge for protein engineering and is a critical test of our understanding of enzyme catalysis. Here we describe the computational design of eight enzymes that use two different catalytic motifs to catalyse the Kemp elimination-a model reaction for proton transfer from carbon-with measured rate enhancements of up to 10(5) and multiple turnovers. Mutational analysis confirms that catalysis depends on the computationally designed active sites, and a high-resolution crystal structure suggests that the designs have close to atomic accuracy. Application of in vitro evolution to enhance the computational designs produced a 〉200-fold increase in k(cat)/K(m) (k(cat)/K(m) of 2,600 M(-1)s(-1) and k(cat)/k(uncat) of 〉10(6)). These results demonstrate the power of combining computational protein design with directed evolution for creating new enzymes, and we anticipate the creation of a wide range of useful new catalysts in the future.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Rothlisberger, Daniela -- Khersonsky, Olga -- Wollacott, Andrew M -- Jiang, Lin -- DeChancie, Jason -- Betker, Jamie -- Gallaher, Jasmine L -- Althoff, Eric A -- Zanghellini, Alexandre -- Dym, Orly -- Albeck, Shira -- Houk, Kendall N -- Tawfik, Dan S -- Baker, David -- Howard Hughes Medical Institute/ -- England -- Nature. 2008 May 8;453(7192):190-5. doi: 10.1038/nature06879.

    Stabilizing isopeptide bonds revealed in gram-positive bacterial pilus structure (2007)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2007-12-08
    Description: Many bacterial pathogens have long, slender pili through which they adhere to host cells. The crystal structure of the major pilin subunit from the Gram-positive human pathogen Streptococcus pyogenes at 2.2 angstroms resolution reveals an extended structure comprising two all-beta domains. The molecules associate in columns through the crystal, with each carboxyl terminus adjacent to a conserved lysine of the next molecule. This lysine forms the isopeptide bonds that link the subunits in native pili, validating the relevance of the crystal assembly. Each subunit contains two lysine-asparagine isopeptide bonds generated by an intramolecular reaction, and we find evidence for similar isopeptide bonds in other cell surface proteins of Gram-positive bacteria. The present structure explains the strength and stability of such Gram-positive pili and could facilitate vaccine development.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kang, Hae Joo -- Coulibaly, Fasseli -- Clow, Fiona -- Proft, Thomas -- Baker, Edward N -- New York, N.Y. -- Science. 2007 Dec 7;318(5856):1625-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Maurice Wilkins Centre for Molecular Biodiscovery, University of Auckland, Auckland 1010, New Zealand.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/18063798" target="_blank"〉PubMed〈/a〉

    A common variant on chromosome 9p21 affects the risk of myocardial infarction (2007)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2007-05-05
    Description: The global endemic of cardiovascular diseases calls for improved risk assessment and treatment. Here, we describe an association between myocardial infarction (MI) and a common sequence variant on chromosome 9p21. This study included a total of 4587 cases and 12,767 controls. The identified variant, adjacent to the tumor suppressor genes CDKN2A and CDKN2B, was associated with the disease with high significance. Approximately 21% of individuals in the population are homozygous for this variant, and their estimated risk of suffering myocardial infarction is 1.64 times as great as that of noncarriers. The corresponding risk is 2.02 times as great for early-onset cases. The population attributable risk is 21% for MI in general and 31% for early-onset cases.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Helgadottir, Anna -- Thorleifsson, Gudmar -- Manolescu, Andrei -- Gretarsdottir, Solveig -- Blondal, Thorarinn -- Jonasdottir, Aslaug -- Jonasdottir, Adalbjorg -- Sigurdsson, Asgeir -- Baker, Adam -- Palsson, Arnar -- Masson, Gisli -- Gudbjartsson, Daniel F -- Magnusson, Kristinn P -- Andersen, Karl -- Levey, Allan I -- Backman, Valgerdur M -- Matthiasdottir, Sigurborg -- Jonsdottir, Thorbjorg -- Palsson, Stefan -- Einarsdottir, Helga -- Gunnarsdottir, Steinunn -- Gylfason, Arnaldur -- Vaccarino, Viola -- Hooper, W Craig -- Reilly, Muredach P -- Granger, Christopher B -- Austin, Harland -- Rader, Daniel J -- Shah, Svati H -- Quyyumi, Arshed A -- Gulcher, Jeffrey R -- Thorgeirsson, Gudmundur -- Thorsteinsdottir, Unnur -- Kong, Augustine -- Stefansson, Kari -- New York, N.Y. -- Science. 2007 Jun 8;316(5830):1491-3.
