    Reconstitution of transcription factor SL1: exclusive binding of TBP by SL1 or TFIID subunits (1994)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1994-12-23
    Description: 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〉

    Splicing of the rolA transcript of Agrobacterium rhizogenes in Arabidopsis (1994)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1994-12-23
    Description: 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〉

    Identification of herpesvirus-like DNA sequences in AIDS-associated Kaposi's sarcoma (1994)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1994-12-16
    Description: 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〉

    Suppression of hyphal formation in Candida albicans by mutation of a STE12 homolog (1994)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1994-12-09
    Description: 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〉

    Circadian clock mutants of cyanobacteria (1994)

    Publication Date: 1994-11-18
    Description: 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〉

    Modulation of epithelial cell growth by intraepithelial gamma delta T cells (1994)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1994-11-18
    Description: 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〉

    A molecular determinant for submillisecond desensitization in glutamate receptors (1994)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1994-11-11
    Description: 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〉

    Genetic dissection of complex traits (1994)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1994-09-30
    Description: 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〉
