    Circadian clock mutants of cyanobacteria (1994)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1994-11-18
    Beschreibung: A diverse set of circadian clock mutants was isolated in a cyanobacterial strain that carries a bacterial luciferase reporter gene attached to a clock-controlled promoter. Among 150,000 clones of chemically mutagenized bioluminescent cells, 12 mutants were isolated that exhibit a broad spectrum of periods (between 16 and 60 hours), and 5 mutants were found that show a variety of unusual patterns, including arrhythmia. These mutations appear to be clock-specific. Moreover, it was demonstrated that in this cyanobacterium it is possible to clone mutant genes by complementation, which provides a means to genetically dissect the circadian mechanism.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kondo, T -- Tsinoremas, N F -- Golden, S S -- Johnson, C H -- Kutsuna, S -- Ishiura, M -- GM37040/GM/NIGMS NIH HHS/ -- MH43836/MH/NIMH NIH HHS/ -- New York, N.Y. -- Science. 1994 Nov 18;266(5188):1233-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉National Institute for Basic Biology, Okazaki, Japan.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7973706" target="_blank"〉PubMed〈/a〉

    Engineering poliovirus as a vaccine vector for the expression of diverse antigens (1994)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1994-09-02
    Beschreibung: As a step toward developing poliovirus as a vaccine vector, poliovirus recombinants were constructed by fusing exogenous peptides (up to 400 amino acids) and an artificial cleavage site for viral protease 3Cpro to the amino terminus of the viral polyprotein. Viral replication proceeded normally. An extended polyprotein was produced in infected cells and proteolytically processed into the complete array of viral proteins plus the foreign peptide, which was excluded from mature virions. The recombinants retained exogenous sequences through successive rounds of replication in culture and in vivo. Infection of animals with recombinants elicited a humoral immune response to the foreign peptides.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Andino, R -- Silvera, D -- Suggett, S D -- Achacoso, P L -- Miller, C J -- Baltimore, D -- Feinberg, M B -- AI22346/AI/NIAID NIH HHS/ -- AI35545/AI/NIAID NIH HHS/ -- RR00169/RR/NCRR NIH HHS/ -- New York, N.Y. -- Science. 1994 Sep 2;265(5177):1448-51.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Microbiology and Immunology, University of California, San Francisco.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8073288" target="_blank"〉PubMed〈/a〉

    Drosophila TAFII150: similarity to yeast gene TSM-1 and specific binding to core promoter DNA (1994)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1994-05-13
    Beschreibung: In Drosophila and human cells, the TATA binding protein (TBP) of the transcription factor IID (TFIID) complex is tightly associated with multiple subunits termed TBP-associated factors (TAFs) that are essential for mediating regulation of RNA polymerase II transcription. The Drosophila TAFII150 has now been molecularly cloned and biochemically characterized. The deduced primary amino acid sequence of dTAFII150 reveals a striking similarity to the essential yeast gene, TSM-1. Furthermore, like dTAFII150, the TSM-1 protein is found associated with the TBP in vivo, thus identifying the first yeast homolog of a TAF associated with TFIID. Both the product of TSM-1 and dTAFII150 bind directly to TBP and dTAFII250, demonstrating a functional similarity between human and yeast TAFs. Surprisingly, DNA binding studies indicate that purified recombinant dTAFII150 binds specifically to DNA sequences overlapping the start site of transcription. The data demonstrate that at least one of the TAFs is a sequence-specific DNA binding protein and that dTAFII150 together with TBP are responsible for TFIID interactions with an extended region of the core promoter.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Verrijzer, C P -- Yokomori, K -- Chen, J L -- Tjian, R -- New York, N.Y. -- Science. 1994 May 13;264(5161):933-41.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Howard Hughes Medical Institute, University of California, Berkeley 94720-3202.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8178153" target="_blank"〉PubMed〈/a〉

    Identification of herpesvirus-like DNA sequences in AIDS-associated Kaposi's sarcoma (1994)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1994-12-16
    Beschreibung: Representational difference analysis was used to isolate unique sequences present in more than 90 percent of Kaposi's sarcoma (KS) tissues obtained from patients with acquired immunodeficiency syndrome (AIDS). These sequences were not present in tissue DNA from non-AIDS patients, but were present in 15 percent of non-KS tissue DNA samples from AIDS patients. The sequences are homologous to, but distinct from, capsid and tegument protein genes of the Gammaherpesvirinae, herpesvirus saimiri and Epstein-Barr virus. These KS-associated herpesvirus-like (KSHV) sequences appear to define a new human herpesvirus.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Chang, Y -- Cesarman, E -- Pessin, M S -- Lee, F -- Culpepper, J -- Knowles, D M -- Moore, P S -- New York, N.Y. -- Science. 1994 Dec 16;266(5192):1865-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Pathology, College of Physicians and Surgeons, Columbia University, New York, NY 10032.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7997879" target="_blank"〉PubMed〈/a〉

    A genetic linkage map for the zebrafish (1994)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1994-04-29
    Beschreibung: To facilitate molecular genetic analysis of vertebrate development, haploid genetics was used to construct a recombination map for the zebrafish Danio (Brachydanio) rerio. The map consists of 401 random amplified polymorphic DNAs (RAPDs) and 13 simple sequence repeats spaced at an average interval of 5.8 centimorgans. Strategies that exploit the advantages of haploid genetics and RAPD markers were developed that quickly mapped lethal and visible mutations and that placed cloned genes on the map. This map is useful for the position-based cloning of mutant genes, the characterization of chromosome rearrangements, and the investigation of evolution in vertebrate genomes.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Postlethwait, J H -- Johnson, S L -- Midson, C N -- Talbot, W S -- Gates, M -- Ballinger, E W -- Africa, D -- Andrews, R -- Carl, T -- Eisen, J S -- 1RO1AI26734/AI/NIAID NIH HHS/ -- HD07470/HD/NICHD NIH HHS/ -- NS23915/NS/NINDS NIH HHS/ -- etc. -- New York, N.Y. -- Science. 1994 Apr 29;264(5159):699-703.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Institute of Neurosciences, University of Oregon, Eugene 97403.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8171321" target="_blank"〉PubMed〈/a〉

    Genetic control of programmed cell death in Drosophila (1994)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1994-04-29
    Beschreibung: A gene, reaper (rpr), that appears to play a central control function for the initiation of programmed cell death (apoptosis) in Drosophila was identified. Virtually all programmed cell death that normally occurs during Drosophila embryogenesis was blocked in embryos homozygous for a small deletion that includes the reaper gene. Mutant embryos contained many extra cells and failed to hatch, but many other aspects of development appeared quite normal. Deletions that include reaper also protected embryos from apoptosis caused by x-irradiation and developmental defects. However, high doses of x-rays induced some apoptosis in mutant embryos, and the resulting corpses were phagocytosed by macrophages. These data suggest that the basic cell death program is intact although it was not activated in mutant embryos. The DNA encompassed by the deletion was cloned and the reaper gene was identified on the basis of the ability of cloned DNA to restore apoptosis to cell death defective embryos in germ line transformation experiments. The reaper gene appears to encode a small peptide that shows no homology to known proteins, and reaper messenger RNA is expressed in cells destined to undergo apoptosis.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉White, K -- Grether, M E -- Abrams, J M -- Young, L -- Farrell, K -- Steller, H -- 5 F32 NS08536/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 1994 Apr 29;264(5159):677-83.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Howard Hughes Medical Institute, Department of Brain and Cognitive Sciences, Cambridge, MA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8171319" target="_blank"〉PubMed〈/a〉

    The Drosophila saxophone gene: a serine-threonine kinase receptor of the TGF-beta superfamily (1994)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1994-03-25
    Beschreibung: The Drosophila decapentaplegic (dpp) gene encodes a transforming growth factor-beta (TGF-beta)-like protein that plays a key role in several aspects of development. Transduction of the DPP signal was investigated by cloning of serine-threonine kinase transmembrane receptors from Drosophila because this type of receptor is specific for the TGF-beta-like ligands. Here evidence is provided demonstrating that the Drosophila saxophone (sax) gene, a previously identified female sterile locus, encodes a TGF-beta-like type I receptor. Embryos from sax mothers and dpp embryos exhibit similar mutant phenotypes during early gastrulation, and these two loci exhibit genetic interactions, which suggest that they are utilized in the same pathway. These data suggest that sax encodes a receptor for dpp.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Xie, T -- Finelli, A L -- Padgett, R W -- New York, N.Y. -- Science. 1994 Mar 25;263(5154):1756-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Waksman Institute, Rutgers University, Piscataway, NJ 08855-0759.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8134837" target="_blank"〉PubMed〈/a〉

    Arabidopsis ABA response gene ABI1: features of a calcium-modulated protein phosphatase (1994)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1994-06-03
    Beschreibung: The Arabidopsis ABI1 locus is essential for a wide spectrum of abscisic acid (ABA) responses throughout plant development. Here, ABI1 was shown to regulate stomatal aperture in leaves and mitotic activity in root meristems. The ABI1 gene was cloned and predicted to encode a signaling protein. Although its carboxyl-terminal domain is related to serine-threonine phosphatase 2C, the ABI1 protein has a unique amino-terminal extension containing an EF hand calcium-binding site. These results suggest that the ABI1 protein is a Ca(2+)-modulated phosphatase and functions to integrate ABA and Ca2+ signals with phosphorylation-dependent response pathways.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Leung, J -- Bouvier-Durand, M -- Morris, P C -- Guerrier, D -- Chefdor, F -- Giraudat, J -- New York, N.Y. -- Science. 1994 Jun 3;264(5164):1448-52.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Institut des Sciences Vegetales, Centre National de la Recherche Scientifique UPR 40, Gif-sur-Yvette, France.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7910981" target="_blank"〉PubMed〈/a〉

    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1994-03-11
    Beschreibung: The pathogenesis of amoebic dysentery is a result of cytolysis of the colonic mucosa by the parasitic protozoan Entamoeba histolytica. The cytolysis results in extensive local ulceration and allows the amoeba to penetrate and metastasize to distant sites. Factors involved in this process were defined with three clones that express hemolytic activities in Escherichia coli. These potential amoebic virulence determinants were also toxic to human colonic epithelial cells, the primary cellular targets in amoebal invasion of the large intestine. The coding sequences for the hemolysins were close to each other on a 2.6-kilobase segment of a 25-kilobase extrachromosomal DNA element. The structural genes for the hemolysins were within inverted repeats that encode ribosomal RNAs.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Jansson, A -- Gillin, F -- Kagardt, U -- Hagblom, P -- New York, N.Y. -- Science. 1994 Mar 11;263(5152):1440-3.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Microbiology, Uppsala University, Sweden.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8128227" target="_blank"〉PubMed〈/a〉

    Fusion of a kinase gene, ALK, to a nucleolar protein gene, NPM, in non-Hodgkin's lymphoma (1994)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1994-03-04
    Beschreibung: The 2;5 chromosomal translocation occurs in most anaplastic large-cell non-Hodgkin's lymphomas arising from activated T lymphocytes. This rearrangement was shown to fuse the NPM nucleolar phosphoprotein gene on chromosome 5q35 to a previously unidentified protein tyrosine kinase gene, ALK, on chromosome 2p23. In the predicted hybrid protein, the amino terminus of nucleophosmin (NPM) is linked to the catalytic domain of anaplastic lymphoma kinase (ALK). Expressed in the small intestine, testis, and brain but not in normal lymphoid cells, ALK shows greatest sequence similarity to the insulin receptor subfamily of kinases. Unscheduled expression of the truncated ALK may contribute to malignant transformation in these lymphomas.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Morris, S W -- Kirstein, M N -- Valentine, M B -- Dittmer, K G -- Shapiro, D N -- Saltman, D L -- Look, A T -- CA 21765/CA/NCI NIH HHS/ -- KO8 CA 01702/CA/NCI NIH HHS/ -- P01 CA 20180/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 1994 Mar 4;263(5151):1281-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Experimental Oncology, St. Jude Children's Research Hospital, Memphis, TN 38105.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8122112" target="_blank"〉PubMed〈/a〉

    A molecular determinant for submillisecond desensitization in glutamate receptors (1994)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1994-11-11
    Beschreibung: The decay of excitatory postsynaptic currents in central neurons mediated by alpha-amino-3-hydroxy-5-methyl-4-isoxazole-propionate (AMPA) receptors is likely to be shaped either by receptor desensitization or by offset after removal of glutamate from the synaptic cleft. Native AMPA receptors show desensitization time constants of 1 to about 10 milliseconds, but the underlying molecular determinants of these large differences are unknown. Cloned AMPA receptors carrying the "flop" splice variants of glutamate receptor subtype C (GluR-C) and GluR-D are shown to have desensitization time constants of around 1 millisecond, whereas those with the "flip" variants are about four times slower. Cerebellar granule cells switch their expression of GluR-D splice variants from mostly flip forms in early stages to predominantly flop forms in the adult rat brain. These findings suggest that rapid desensitization of AMPA receptors can be regulated by the expression and alternative splicing of GluR-D gene transcripts.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Mosbacher, J -- Schoepfer, R -- Monyer, H -- Burnashev, N -- Seeburg, P H -- Ruppersberg, J P -- Wellcome Trust/United Kingdom -- New York, N.Y. -- Science. 1994 Nov 11;266(5187):1059-62.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Max-Planck-Institut fur medizinische Forschung, Heidelberg, Germany.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7973663" target="_blank"〉PubMed〈/a〉

    Requirement for the yeast gene LON in intramitochondrial proteolysis and maintenance of respiration (1994)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1994-04-08
    Beschreibung: The role of protein degradation in mitochondrial homeostasis was explored by cloning of a gene from Saccharomyces cerevisiae that encodes a protein resembling the adenosine triphosphate (ATP)-dependent bacterial protease Lon. The predicted yeast protein has a typical mitochondrial matrix-targeting sequence at its amino terminus. Yeast cells lacking a functional LON gene contained a nonfunctional mitochondrial genome, were respiratory-deficient, and lacked an ATP-dependent proteolytic activity present in the mitochondria of Lon+ cells. Lon- cells were also impaired in their ability to catalyze the energy-dependent degradation of several mitochondrial matrix proteins and they accumulated electron-dense inclusions in their mitochondrial matrix.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Suzuki, C K -- Suda, K -- Wang, N -- Schatz, G -- New York, N.Y. -- Science. 1994 Apr 8;264(5156):273-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Biozentrum der Universitat Basel, Switzerland.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8146662" target="_blank"〉PubMed〈/a〉

    Association of intestinal peptide transport with a protein related to the cadherin superfamily (1994)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1994-04-15
    Beschreibung: The first step in oral absorption of many medically important peptide-based drugs is mediated by an intestinal proton-dependent peptide transporter. This transporter facilitates the oral absorption of beta-lactam antibiotics and angiotensin-converting enzyme inhibitors from the intestine into enterocytes lining the luminal wall. A monoclonal antibody that blocked uptake of cephalexin was used to identify and clone a gene that encodes an approximately 92-kilodalton membrane protein that was associated with the acquisition of peptide transport activity by transport-deficient cells. The amino acid sequence deduced from the complementary DNA sequence of the cloned gene indicated that this transport-associated protein shares several conserved structural elements with the cadherin superfamily of calcium-dependent, cell-cell adhesion proteins.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Dantzig, A H -- Hoskins, J A -- Tabas, L B -- Bright, S -- Shepard, R L -- Jenkins, I L -- Duckworth, D C -- Sportsman, J R -- Mackensen, D -- Rosteck, P R Jr -- New York, N.Y. -- Science. 1994 Apr 15;264(5157):430-3.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Lilly Research Laboratories, Eli Lilly and Company, Indianapolis, IN 46285.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8153632" target="_blank"〉PubMed〈/a〉

    Crystal structure of rat DNA polymerase beta: evidence for a common polymerase mechanism (1994)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1994-06-24
    Beschreibung: Structures of the 31-kilodalton catalytic domain of rat DNA polymerase beta (pol beta) and the whole 39-kilodalton enzyme were determined at 2.3 and 3.6 angstrom resolution, respectively. The 31-kilodalton domain is composed of fingers, palm, and thumb subdomains arranged to form a DNA binding channel reminiscent of the polymerase domains of the Klenow fragment of Escherichia coli DNA polymerase I, HIV-1 reverse transcriptase, and bacteriophage T7 RNA polymerase. The amino-terminal 8-kilodalton domain is attached to the fingers subdomain by a flexible hinge. The two invariant aspartates found in all polymerase sequences and implicated in catalytic activity have the same geometric arrangement within structurally similar but topologically distinct palms, indicating that the polymerases have maintained, or possibly re-evolved, a common nucleotidyl transfer mechanism. The location of Mn2+ and deoxyadenosine triphosphate in pol beta confirms the role of the invariant aspartates in metal ion and deoxynucleoside triphosphate binding.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Sawaya, M R -- Pelletier, H -- Kumar, A -- Wilson, S H -- Kraut, J -- CA17374/CA/NCI NIH HHS/ -- ES06839/ES/NIEHS NIH HHS/ -- GM10928/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1994 Jun 24;264(5167):1930-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Chemistry, University of California, San Diego 92093-0317.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7516581" target="_blank"〉PubMed〈/a〉

    Beschreibung: The role played in immune surveillance by gamma delta T cells residing in various epithelia has not been clear. It is shown here that activated gamma delta T cells obtained from skin and intestine express the epithelial cell mitogen keratinocyte growth factor (KGF). In contrast, intraepithelial alpha beta T cells, as well as all lymphoid alpha beta and gamma delta T cell populations tested, did not produce KGF or promote the growth of cultured epithelial cells. These results suggest that intraepithelial gamma delta T cells function in surveillance and in repair of damaged epithelial tissues.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Boismenu, R -- Havran, W L -- AI32751/AI/NIAID NIH HHS/ -- New York, N.Y. -- Science. 1994 Nov 18;266(5188):1253-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Immunology, Scripps Research Institute, La Jolla, CA 92037.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7973709" target="_blank"〉PubMed〈/a〉

    Requirement of human renal water channel aquaporin-2 for vasopressin-dependent concentration of urine (1994)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1994-04-01
    Beschreibung: Concentration of urine in mammals is regulated by the antidiuretic hormone vasopressin. Binding of vasopressin to its V2 receptor leads to the insertion of water channels in apical membranes of principal cells in collecting ducts. In nephrogenic diabetes insipidus (NDI), the kidney fails to concentrate urine in response to vasopressin. A male patient with an autosomal recessive form of NDI was found to be a compound heterozygote for two mutations in the gene encoding aquaporin-2, a water channel. Functional expression studies in Xenopus oocytes revealed that each mutation resulted in nonfunctional water channel proteins. Thus, aquaporin-2 is essential for vasopressin-dependent concentration of urine.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Deen, P M -- Verdijk, M A -- Knoers, N V -- Wieringa, B -- Monnens, L A -- van Os, C H -- van Oost, B A -- New York, N.Y. -- Science. 1994 Apr 1;264(5155):92-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Cell Physiology, University of Nijmegen, Netherlands.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8140421" target="_blank"〉PubMed〈/a〉

    Beschreibung: A homozygous mutation in the kinase domain of ZAP-70, a T cell receptor-associated protein tyrosine kinase, produced a distinctive form of human severe combined immunodeficiency. Manifestations of this disorder included profound immunodeficiency, absence of peripheral CD8+ T cells, and abundant peripheral CD4+ T cells that were refractory to T cell receptor-mediated activation. These findings demonstrate that ZAP-70 is essential for human T cell function and suggest that CD4+ and CD8+ T cells depend on different intracellular signaling pathways to support their development or survival.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Elder, M E -- Lin, D -- Clever, J -- Chan, A C -- Hope, T J -- Weiss, A -- Parslow, T G -- AI29313/AI/NIAID NIH HHS/ -- GM43574/GM/NIGMS NIH HHS/ -- RR01271/RR/NCRR NIH HHS/ -- etc. -- New York, N.Y. -- Science. 1994 Jun 10;264(5165):1596-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Pediatrics, University of California, San Francisco 94143-0110.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8202712" target="_blank"〉PubMed〈/a〉

    A protein phosphatase 2C involved in ABA signal transduction in Arabidopsis thaliana (1994)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1994-06-03
    Beschreibung: The plant hormone abscisic acid (ABA) mediates various responses such as stomatal closure, the maintenance of seed dormancy, and the inhibition of plant growth. All three responses are affected in the ABA-insensitive mutant abi1 of Arabidopsis thaliana, suggesting that an early step in the signaling of ABA is controlled by the ABI1 locus. The ABI1 gene was cloned by chromosome walking, and a missense mutation was identified in the structural gene of the abi1 mutant. The ABI1 gene encodes a protein with high similarity to protein serine or threonine phosphatases of type 2C with the novel feature of a putative Ca2+ binding site. Thus, the control of the phosphorylation state of cell signaling components by the ABI1 product could mediate pleiotropic hormone responses.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Meyer, K -- Leube, M P -- Grill, E -- New York, N.Y. -- Science. 1994 Jun 3;264(5164):1452-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Institute of Plant Sciences, Swiss Federal Institute of Technology, Zurich.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8197457" target="_blank"〉PubMed〈/a〉

    An interleukin-4-induced transcription factor: IL-4 Stat (1994)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1994-09-16
    Beschreibung: Interleukin-4 (IL-4) is an immunomodulatory cytokine secreted by activated T lymphocytes, basophils, and mast cells. It plays an important role in modulating the balance of T helper (Th) cell subsets, favoring expansion of the Th2 lineage relative to Th1. Imbalance of these T lymphocyte subsets has been implicated in immunological diseases including allergy, inflammation, and autoimmune disease. IL-4 may mediate its biological effects, at least in part, by activating a tyrosine-phosphorylated DNA binding protein. This protein has now been purified and its encoding gene cloned. Examination of the primary amino acid sequence of this protein indicates that it is a member of the signal transducers and activators of transcription (Stat) family of DNA binding proteins, hereby designated IL-4 Stat. Study of the inhibitory activities of phosphotyrosine-containing peptides derived from the intracellular domain of the IL-4 receptor provided evidence for direct coupling of receptor and transcription factor during the IL-4 Stat activation cycle. Such observations indicate that IL-4 Stat has the same functional domain for both receptor coupling and dimerization.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hou, J -- Schindler, U -- Henzel, W J -- Ho, T C -- Brasseur, M -- McKnight, S L -- New York, N.Y. -- Science. 1994 Sep 16;265(5179):1701-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Tularik, Inc., South San Francisco, CA 94080.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8085155" target="_blank"〉PubMed〈/a〉

    Reconstitution of transcription factor SL1: exclusive binding of TBP by SL1 or TFIID subunits (1994)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1994-12-23
    Beschreibung: RNA polymerase I and II transcription factors SL1 and TFIID, respectively, are composed of the TATA-binding protein (TBP) and a set of TBP-associated factors (TAFs) responsible for promoter recognition. How the universal transcription factor TBP becomes committed to a TFIID or SL1 complex has not been known. Complementary DNAs encoding each of the three TAFIs that are integral components of SL1 have not been isolated. Analysis of subunit interactions indicated that the three TAFIs can bind individually and specifically to TBP. In addition, these TAFIs interact with each other to form a stable TBP-TAF complex. When TBP was bound first by either TAFI110, 63, or 48, subunits of TFIID such as TAFII250 and 150 did not bind TBP. Conversely, if TBP first formed a complex with TAFII250 or 150, the subunits of SL1 did not bind TBP. These results suggest that a mutually exclusive binding specificity for TBP intrinsic to SL1 and TFIID subunits directs the formation of promoter- and RNA polymerase-selective TBP-TAF complexes.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Comai, L -- Zomerdijk, J C -- Beckmann, H -- Zhou, S -- Admon, A -- Tjian, R -- New York, N.Y. -- Science. 1994 Dec 23;266(5193):1966-72.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Howard Hughes Medical Institute, Department of Molecular and Cell Biology, University of California at Berkeley 94720-3204.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7801123" target="_blank"〉PubMed〈/a〉

PRS2 is a resistance gene of Arabidopsis thaliana that confers resistance against Pseudomonas syringae bacteria that express avirulence gene avrRpt2. RPS2 was isolated by the use of a positional cloning strategy. The derived amino acid sequence of RPS2 contains leucine-rich repeat, membrane-spanning, leucine zipper, and P loop domains. The function of the RPS2 gene product in defense signal transduction is postulated to involve nucleotide triphosphate binding and protein-protein interactions and may also involve the reception of an elicitor produced by the avirulent pathogen.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Bent, A F -- Kunkel, B N -- Dahlbeck, D -- Brown, K L -- Schmidt, R -- Giraudat, J -- Leung, J -- Staskawicz, B J -- New York, N.Y. -- Science. 1994 Sep 23;265(5180):1856-60.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Plant Biology, University of California, Berkeley 94720.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8091210" target="_blank"〉PubMed〈/a〉

    Suppression of hyphal formation in Candida albicans by mutation of a STE12 homolog (1994)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1994-12-09
    Beschreibung: A Candida albicans gene (CPH1) was cloned that encodes a protein homologous to Saccharomyces cerevisiae Ste12p, a transcription factor that is the target of the pheromone response mitogen-activated protein kinase cascade. CPH1 complements both the mating defect of ste12 haploids and the filamentous growth defect of ste12/ste12 diploids. Candida albicans strains without a functional CPH1 gene (cph1/cph1) show suppressed hyphal formation on solid medium. However, cph1/cph1 strains can still form hyphae in liquid culture and in response to serum. Thus, filamentous growth may be activated in C. albicans by the same signaling kinase cascade that activates Ste12p in S. cerevisiae; however, alternative pathways may exist in C. albicans.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Liu, H -- Kohler, J -- Fink, G R -- GM402661/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1994 Dec 9;266(5191):1723-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Whitehead Institute for Biomedical Research, Cambridge, MA 02142.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7992058" target="_blank"〉PubMed〈/a〉

    Beschreibung: The TATA-binding protein TBP appears to be essential for all transcription in eukaryotic cell nuclei, which suggests that its function was established early in evolution. Archaebacteria constitute a kingdom of organisms distinct from eukaryotes and eubacteria. Archaebacterial gene regulatory sequences often map to TATA box-like motifs. Here it is shown that the archaebacterium Pyrococcus woesei expresses a protein with structural and functional similarity to eukaryotic TBP molecules. This suggests that TBP's role in transcription was established before the archaebacterial and eukaryotic lineages diverged and that the transcription systems of archaebacteria and eukaryotes are fundamentally homologous.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Rowlands, T -- Baumann, P -- Jackson, S P -- Wellcome Trust/United Kingdom -- New York, N.Y. -- Science. 1994 May 27;264(5163):1326-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Wellcome/CRC Institute, Cambridge, UK.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8191287" target="_blank"〉PubMed〈/a〉

    Specification of pore properties by the carboxyl terminus of inwardly rectifying K+ channels (1994)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1994-05-06
    Beschreibung: Inwardly rectifying potassium (K+) channels (IRKs) maintain the resting membrane potential of cells and permit prolonged depolarization, such as during the cardiac action potential. Inward rectification may result from block of the ion conduction pore by intracellular magnesium (Mgi2+). Two members of this family, IRK1 and ROMK1, which share 40 percent amino acid identity, differ markedly in single-channel K+ conductance and sensitivity to block by Mgi2+. The conserved H5 regions were hypothesized to determine these pore properties because they have this function in voltage-dependent K+ channels and in cyclic nucleotide-gated channels. However, exchange of the H5 region between IRK1 and ROMK1 had no effect on rectification and little or no effect on K+ conductance. By contrast, exchange of the amino- and carboxyl-terminal regions together transferred Mg2+ blockade and K+ conductance of IRK1 to ROMK1. Exchange of the carboxyl but not the amino terminus had a similar effect. Therefore, the carboxyl terminus appears to have a major role in specifying the pore properties of IRKs.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Taglialatela, M -- Wible, B A -- Caporaso, R -- Brown, A M -- HL36930/HL/NHLBI NIH HHS/ -- HL37044/HL/NHLBI NIH HHS/ -- NS23877/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 1994 May 6;264(5160):844-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Molecular Physiology and Biophysics, Baylor College of Medicine, Houston, TX 77030.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8171340" target="_blank"〉PubMed〈/a〉

    Details
    Publikationsdatum: 1994-12-23
    Beschreibung: The rolA gene encoded on the Ri plasmid A4 of Agrobacterium rhizogenes is one of the transferred (TL-DNA) genes involved in the pathogenesis of hairy-root disease in plants. The function of the 100-amino acid protein product of rolA is unknown, although its expression causes physiological and developmental alterations in transgenic plants. The rolA gene of A. rhizogenes contains an intron in its untranslated leader region that has features typical of plant pre-messenger RNA introns. Transcription and splicing of the rolA pre-messenger RNA occur in the plant cell.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Magrelli, A -- Langenkemper, K -- Dehio, C -- Schell, J -- Spena, A -- New York, N.Y. -- Science. 1994 Dec 23;266(5193):1986-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Max-Plank-Institut fur Zuchtungsforschung, Cologne, Germany.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7528444" target="_blank"〉PubMed〈/a〉

    cDNA cloning and interferon gamma down-regulation of proteasomal subunits X and Y (1994)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1994-08-26
    Beschreibung: Proteasomes are the proteolytic complex responsible for major histocompatibility complex (MHC) class I-restricted antigen presentation. Interferon gamma treatment increases expression MHC-encoded LMP2 and LMP7 subunits of the proteasome and decreases expression of two proteasome subunits, named X and Y, which alters the proteolytic specificity of proteasomes. Molecular cloning of complementary DNAs encoding X and Y showed that their proteins are proteasomal subunits with high amino acid similarity to LMP7 and LMP2, respectively. Thus, interferon gamma may induce subunit replacements of X and Y by LMP7 and LMP2, respectively, producing proteasomes perhaps more appropriate for the immunological processing of endogenous antigens.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Akiyama, K -- Yokota, K -- Kagawa, S -- Shimbara, N -- Tamura, T -- Akioka, H -- Nothwang, H G -- Noda, C -- Tanaka, K -- Ichihara, A -- New York, N.Y. -- Science. 1994 Aug 26;265(5176):1231-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Urology, School of Medicine, University of Tokushima, Japan.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8066462" target="_blank"〉PubMed〈/a〉

    Cloning of a Grb2 isoform with apoptotic properties (1994)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1994-05-13
    Beschreibung: Growth factor receptor-bound protein 2 (Grb2) links tyrosine-phosphorylated proteins to a guanine nucleotide releasing factor of the son of sevenless (Sos) class by attaching to the former by its Src homology 2 (SH2) moiety and to the latter by its SH3 domains. An isoform of grb2 complementary DNA (cDNA) was cloned that has a deletion in the SH2 domain. The protein encoded by this cDNA, Grb3-3, did not bind to phosphorylated epidermal growth factor receptor (EGFR) but retained functional SH3 domains and inhibited EGF-induced transactivation of a Ras-responsive element. The messenger RNA encoding Grb3-3 was expressed in high amounts in the thymus of rats at an age when massive negative selection of thymocytes occurs. Microinjection of Grb3-3 into Swiss 3T3 fibroblasts induced apoptosis. These findings indicate that Grb3-3, by acting as a dominant negative protein over Grb2 and by suppressing proliferative signals, may trigger active programmed cell death.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Fath, I -- Schweighoffer, F -- Rey, I -- Multon, M C -- Boiziau, J -- Duchesne, M -- Tocque, B -- New York, N.Y. -- Science. 1994 May 13;264(5161):971-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Rhone-Poulenc Rorer, Centre de Recherche de Vitry-Alfortville, Vitry sur Seine, France.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8178156" target="_blank"〉PubMed〈/a〉

    Genetic dissection of complex traits (1994)

    Details
    Publikationsdatum: 1994-09-30
    Beschreibung: Medical genetics was revolutionized during the 1980s by the application of genetic mapping to locate the genes responsible for simple Mendelian diseases. Most diseases and traits, however, do not follow simple inheritance patterns. Genetics have thus begun taking up the even greater challenge of the genetic dissection of complex traits. Four major approaches have been developed: linkage analysis, allele-sharing methods, association studies, and polygenic analysis of experimental crosses. This article synthesizes the current state of the genetic dissection of complex traits--describing the methods, limitations, and recent applications to biological problems.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lander, E S -- Schork, N J -- HG00098/HG/NHGRI NIH HHS/ -- New York, N.Y. -- Science. 1994 Sep 30;265(5181):2037-48.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Whitehead Institute for Biomedical Research, Cambridge, MA 02142.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8091226" target="_blank"〉PubMed〈/a〉

    Publikationsdatum: 1994-01-14
    Beschreibung: Isoniazid (isonicotinic acid hydrazide, INH) is one of the most widely used antituberculosis drugs, yet its precise target of action on Mycobacterium tuberculosis is unknown. A missense mutation within the mycobacterial inhA gene was shown to confer resistance to both INH and ethionamide (ETH) in M. smegmatis and in M. bovis. The wild-type inhA gene also conferred INH and ETH resistance when transferred on a multicopy plasmid vector to M. smegmatis and M. bovis BCG. The InhA protein shows significant sequence conservation with the Escherichia coli enzyme EnvM, and cell-free assays indicate that it may be involved in mycolic acid biosynthesis. These results suggest that InhA is likely a primary target of action for INH and ETH.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Banerjee, A -- Dubnau, E -- Quemard, A -- Balasubramanian, V -- Um, K S -- Wilson, T -- Collins, D -- de Lisle, G -- Jacobs, W R Jr -- AI27160/AI/NIAID NIH HHS/ -- UO1AI30189/AI/NIAID NIH HHS/ -- New York, N.Y. -- Science. 1994 Jan 14;263(5144):227-30.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Howard Hughes Medical Institute, Albert Einstein College of Medicine, Bronx, NY 10461.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8284673" target="_blank"〉PubMed〈/a〉

    Beschreibung: A phage display system was developed and used to select zinc finger proteins with altered DNA-binding specificities. The three zinc fingers of the Zif268 protein were expressed on the surface of filamentous phage, and a library of variants was prepared by randomizing critical amino acids in the first zinc finger. Affinity selections, using DNA sites with base changes in the region recognized by the first finger, yielded Zif268 variants that bound tightly and specifically to the new sites. This phage system provides a tool for the study of protein-DNA interactions and may offer a general method for selecting zinc finger proteins that recognize desired target sites on double-stranded DNA.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Rebar, E J -- Pabo, C O -- New York, N.Y. -- Science. 1994 Feb 4;263(5147):671-3.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biology, Massachusetts Institute of Technology, Cambridge 02139.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8303274" target="_blank"〉PubMed〈/a〉

    Beschreibung: Plants contain most of the growth hormone indole-3-acetic acid (IAA) in conjugated forms believed to be inactive in promoting growth. The iaglu gene, which controls the first step in the biosynthesis of the IAA conjugates of Zea mays, encodes (uridine 5'-diphosphate-glucose:indol-3-ylacetyl)-beta-D-glucosyl transferase. Protein synthesized by Escherichia coli that contained cloned 1-O-beta-D-indol-3-ylacetyl-glucose complementary DNA (cDNA) was catalytically active. The predicted amino acid sequence of the cDNA was confirmed by amino-terminal sequencing of the purified enzyme. Homologous nucleotide sequences were found in all plants tested. The blockage or enhancement of iaglu expression may permit regulation of plant growth.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Szerszen, J B -- Szczyglowski, K -- Bandurski, R S -- New York, N.Y. -- Science. 1994 Sep 16;265(5179):1699-701.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Botany and Plant Pathology, Michigan State University, East Lansing 48824.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8085154" target="_blank"〉PubMed〈/a〉

    Ku80: product of the XRCC5 gene and its role in DNA repair and V(D)J recombination (1994)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1994-09-02
    Beschreibung: The radiosensitive mutant xrs-6, derived from Chinese hamster ovary cells, is defective in DNA double-strand break repair and in ability to undergo V(D)J recombination. The human XRCC5 DNA repair gene, which complements this mutant, is shown here through genetic and biochemical evidence to be the 80-kilodalton subunit of the Ku protein. Ku binds to free double-stranded DNA ends and is the DNA-binding component of the DNA-dependent protein kinase. Thus, the Ku protein is involved in DNA repair and in V(D)J recombination, and these results may also indicate a role for the Ku-DNA-dependent protein kinase complex in those same processes.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Taccioli, G E -- Gottlieb, T M -- Blunt, T -- Priestley, A -- Demengeot, J -- Mizuta, R -- Lehmann, A R -- Alt, F W -- Jackson, S P -- Jeggo, P A -- AI 20047/AI/NIAID NIH HHS/ -- Wellcome Trust/United Kingdom -- New York, N.Y. -- Science. 1994 Sep 2;265(5177):1442-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Howard Hughes Medical Institute, Children's Hospital, Boston, MA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8073286" target="_blank"〉PubMed〈/a〉

    Engineered biosynthesis of a complete macrolactone in a heterologous host (1994)

    Details
    Publikationsdatum: 1994-07-22
    Beschreibung: Macrocyclic polyketides have been subjects of great interest in synthetic and biosynthetic chemistry because of their structural complexity and medicinal activities. With expression of the entire 6-deoxyerythronolide B synthase (DEBS) (10,283 amino acids) in a heterologous host, substantial quantities of 6-deoxyerythronolide B (6dEB), the aglycone of the macrolide antibiotic erythromycin, and 8,8a-deoxyoleandolide, a 14-membered lactone ring identical to 6dEB except for a methyl group side chain in place of an ethyl unit, were synthesized in Streptomyces coelicolor. The biosynthetic strategy utilizes a genetic approach that facilitates rapid structural manipulation of DEBS or other modular polyketide synthases (PKSs), including those found in actinomycetes with poorly developed genetic methods. From a technological viewpoint, this approach should allow the rational design of biosynthetic products and may eventually lead to the generation of diverse polyketide libraries by means of combinatorial cloning of naturally occurring and mutant PKS modules.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kao, C M -- Katz, L -- Khosla, C -- New York, N.Y. -- Science. 1994 Jul 22;265(5171):509-12.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Chemical Engineering, Stanford University, CA 94305-5025.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8036492" target="_blank"〉PubMed〈/a〉

    Secretion of human interferons by yeast (1983)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1983-02-11
    Beschreibung: Plasmids were constructed to direct synthesis of the human interferons IFN-alpha 1, IFN-alpha 2, and IFN-gamma in the yeast Saccharomyces cerevisiae. Expression of IFN genes containing coding sequences for secretion signals resulted in the secretion of IFN activity. A large proportion of the IFN-alpha 1 and IFN-alpha 2 isolated from the yeast cell growth media had the same amino termini as the natural mature interferons, suggesting a removal of the signal sequences identical to that of human cells. These results show that a lower eukaryote, such as yeast, can utilize and process a human signal sequence.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hitzeman, R A -- Leung, D W -- Perry, L J -- Kohr, W J -- Levine, H L -- Goeddel, D V -- New York, N.Y. -- Science. 1983 Feb 11;219(4585):620-5.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6186023" target="_blank"〉PubMed〈/a〉

    Localization of a Plasmodium surface antigen epitope by Tn5 mutagenesis mapping of a recombinant cDNA clone (1983)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1983-06-17
    Beschreibung: A recombinant complementary DNA clone from Plasmodium knowlesi makes a beta-lactamase fusion polypeptide in Escherichia coli that reacts with a monoclonal antibody to a Plasmodium surface antigen. An epitope of the surface antigen was localized by transposon Tn5 mutagenesis mapping of the complementary DNA clone. The Tn5 mutation having the farthest 5' insert into the complementary DNA portion of the chimeric gene, giving the shortest truncated protein that maintained the ability to bind monoclonal antibody, defined the location of the epitope.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lupski, J R -- Ozaki, L S -- Ellis, J -- Godson, G N -- New York, N.Y. -- Science. 1983 Jun 17;220(4603):1285-8.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6190227" target="_blank"〉PubMed〈/a〉

    Publikationsdatum: 1983-02-11
    Beschreibung: The surface of rabies virus is composed of an approximately 60,000 dalton glycoprotein, in which most of the antigenic and immunogenic determinants of the virus reside. We have constructed plasmids for the direct expression in Escherichia coli of the mature full length rabies glycoprotein gene and also for the expression of a glycoprotein gene which has been truncated to exclude the coding region for a hydrophobic, possibly transmembrane, domain of the protein. Escherichia coli harboring the plasmids synthesize analog proteins which conform by several biochemical and antigenic criteria to rabies glycoprotein.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Yelverton, E -- Norton, S -- Obijeski, J F -- Goeddel, D V -- New York, N.Y. -- Science. 1983 Feb 11;219(4585):614-20.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6297004" target="_blank"〉PubMed〈/a〉

    Differential gene expression in the gastrula of Xenopus laevis (1983)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1983-10-14
    Beschreibung: A modified cloning method designed to produce differential complementary DNA libraries permits the isolation of sequences that are present in the RNA population of any developmental stage or tissue, but are not present or are much less abundant in another stage or tissue. Selective complementary DNA cloning is especially useful when the differentially expressed RNA's are of low to moderate abundance in the cells in which they occur. A class of cytoplasmic polyadenylated RNA's differentially expressed in gastrula embryos of Xenopus laevis (DG RNA's) has been isolated. These DG RNA's occur very rarely or not at all in unfertilized eggs and blastulae, accumulate as the result of transcription before and during gastrulation, and, with some exceptions, decline in abundance as development proceeds. Many of these RNA molecules appear to be translated at the gastrula stage. Thus, DG RNA's may encode proteins that are important in the process of gastrulation.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Sargent, T D -- Dawid, I B -- New York, N.Y. -- Science. 1983 Oct 14;222(4620):135-9.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6688681" target="_blank"〉PubMed〈/a〉

    Beschreibung: Human insulin produced by recombinant DNA technology is the first commercial health care product derived from this technology. Work on this product was initiated before there were federal guidelines for large-scale recombinant DNA work or commercial development of recombinant DNA products. The steps taken to facilitate acceptance of large-scale work and proof of the identity and safety of such a product are described. While basic studies in recombinant DNA technology will continue to have a profound impact on research in the life sciences, commercial applications may well be controlled by economic conditions and the availability of investment capital.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Johnson, I S -- New York, N.Y. -- Science. 1983 Feb 11;219(4585):632-7.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6337396" target="_blank"〉PubMed〈/a〉

    Beschreibung: Three types of tumors termed plasmacytomas (ABPC's), lymphosarcomas (ABLS's), and plasmacytoid lymphosarcomas (ABPL's) arise in BALB/c mice treated with pristane and Abelson murine leukemia virus (A-MuLV). While most ABPC's and BLS's contain integrated A-MuLV proviral genome and synthesize the v-abl RNA, most ABPL's do not. The ABPL tumors were examined for the expression of other oncogenes that may be associated with their transformed state, in the absence of transforming virus. These tumors expressed abundant c-myb RNA of unusually large size and showed DNA rearrangements of the c-myb locus.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Mushinski, J F -- Potter, M -- Bauer, S R -- Reddy, E P -- New York, N.Y. -- Science. 1983 May 20;220(4599):795-8.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6687762" target="_blank"〉PubMed〈/a〉

    Publikationsdatum: 1983-08-26
    Beschreibung: The complete nucleotide sequence of the diphtheria tox228 gene encoding the nontoxic serologically related protein CRM228 has been determined. A comparison of the predicted amino acid sequence with the available amino acid sequences from the wild-type toxin made it possible to deduce essentially the entire nucleotide sequence of the wild-type tox gene. The signal peptide of pro-diphtheria toxin and the putative tox promoter have been identified, a highly symmetrical nucleotide sequence downstream of the toxin gene has been detected; this region may be the corynebacteriophage beta attachment site (attP). The cloned toxin gene was expressed at a low level in Escherichia coli.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kaczorek, M -- Delpeyroux, F -- Chenciner, N -- Streeck, R E -- Murphy, J R -- Boquet, P -- Tiollais, P -- New York, N.Y. -- Science. 1983 Aug 26;221(4613):855-8.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6348945" target="_blank"〉PubMed〈/a〉

A portion of the intervening sequence between the heavy chain joining region (Jh) and the constant region of the mu chain (Cmu) can enhance transcription when it is cloned either 5' or 3' to the SV40 early promoter.

    Genetic expression in the developing brain (1983)

    Publikationsdatum: 1983-05-27
    Beschreibung: The adult mouse brain contains complex populations of polyadenylated [poly(A)+] and nonpolyadenylated [poly(A)-] messenger RNA's (mRNA's). These mRNA's are separate sequence populations, similar in complexity, and in combination are equivalent to approximately 150,000 different mRNA sequences, of average length. Essentially all of the "adult" poly(A)+ mRNA's are present in the brain at birth. In contrast, most of the poly(A)- mRNA's are absent. Brain poly(A)- mRNA's begin to appear soon after birth, but the full adult complement is not reached until young adulthood. This suggests that these poly(A)- mRNA's specify proteins required for the biological capabilities of the brain that emerge during the course of postnatal development.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Chaudhari, N -- Hahn, W E -- NS10813/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 1983 May 27;220(4600):924-8.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6189184" target="_blank"〉PubMed〈/a〉

    Ectopic pro-opiolipomelanocortin: sequence of cDNA coding for beta-melanocyte-stimulating hormone and beta-endorphin (1983)
    American Association for the Advancement of Science (AAAS)

    Publikationsdatum: 1983-05-13
    Beschreibung: A recombinant bacterial plasmid, pMS1, was constructed that contains 318 nucleotides complementary to a portion of pro-opiolipomelanocortin (proOLMC) messenger RNA from an ectopic adrenocorticotropin-producing tumor. The cloned complementary DNA insert, which contains the sequence that codes for all of the beta-melanocyte-stimulating hormone and beta-endorphin portions of proOLMC, as well as the 3' nontranslated section, is identical to the genomic sequence. Hybridization of tumor proOLMC complementary DNA to RNA subjected to electrophoresis and transferred to a nitrocellulose filter revealed two proOLMC messenger RNA species in the tumor polyadenylated RNA, but only one in pituitary polyadenylated RNA. At least one of the tumor proOLMC messenger RNA's is similar, if not identical, to human pituitary proOLMC messenger RNA.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉DeBold, C R -- Schworer, M E -- Connor, T B -- Bird, R E -- Orth, D N -- 2-R01-GM25526/GM/NIGMS NIH HHS/ -- 5-R01-CA11685/CA/NCI NIH HHS/ -- 5-R25-CA19429/CA/NCI NIH HHS/ -- etc. -- New York, N.Y. -- Science. 1983 May 13;220(4598):721-3.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6301015" target="_blank"〉PubMed〈/a〉

    High-efficiency ligation and recombination of DNA fragments by vertebrate cells (1983)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1983-05-06
    Beschreibung: DNA-mediated gene transfer (transfection) is used to introduce specific genes into vertebrate cells. Events soon after transfection were quantitatively analyzed by determining the infectivity of the DNA from an avian retrovirus and of mixtures of subgenomic fragments of this DNA. The limiting step of transfection with two DNA molecules is the uptake by a single cell of both DNA's in a biologically active state. Transfected cells mediate ligation and recombination of physically unlinked DNA's at nearly 100 percent efficiency.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Miller, C K -- Temin, H M -- CA-07175/CA/NCI NIH HHS/ -- CA-09135/CA/NCI NIH HHS/ -- CA-22443/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 1983 May 6;220(4597):606-9.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6301012" target="_blank"〉PubMed〈/a〉

    Isolation of human C-reactive protein complementary DNA and localization of the gene to chromosome 1 (1983)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1983-07-01
    Beschreibung: With a synthetic oligonucleotide mixture as probe, complementary DNA clones of C-reactive protein were isolated from an adult human liver complementary DNA library. The clones ranged in size from 700 to 1100 base pairs and were identified by partial DNA sequence analysis. One complementary DNA clone was used as a probe for hybridization with human-rodent DNA's isolated from somatic cell hybrids and bound to nitrocellulose filters (Southern blot analysis) to assign the human C-reactive protein gene to chromosome 1.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Whitehead, A S -- Bruns, G A -- Markham, A F -- Colten, H R -- Woods, D E -- AI15033/AI/NIAID NIH HHS/ -- HD4807/HD/NICHD NIH HHS/ -- HL22487/HL/NHLBI NIH HHS/ -- etc. -- New York, N.Y. -- Science. 1983 Jul 1;221(4605):69-71.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6857266" target="_blank"〉PubMed〈/a〉

    Yeast RNA polymerase II genes: isolation with antibody probes (1983)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1983-11-18
    Beschreibung: Genes encoding yeast RNA polymerase II subunits were cloned. Efficient isolation of these genes was accomplished by probing a phage lambda gt11 recombinant DNA expression library with polyvalent antibodies directed against purified yeast RNA polymerase II. The identity of genes that specify the largest RNA polymerase II subunits, the 220,000- and 150,000-dalton polypeptides, was confirmed by competitive radioimmune assay. Both of these genes exist in single copy in the yeast Saccharomyces cerevisiae.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Young, R A -- Davis, R W -- New York, N.Y. -- Science. 1983 Nov 18;222(4625):778-82.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6356359" target="_blank"〉PubMed〈/a〉
