    Description: Glaucoma is a major cause of blindness and is characterized by progressive degeneration of the optic nerve and is usually associated with elevated intraocular pressure. Analyses of sequence tagged site (STS) content and haplotype sharing between families affected with chromosome 1q-linked open angle glaucoma (GLC1A) were used to prioritize candidate genes for mutation screening. A gene encoding a trabecular meshwork protein (TIGR) mapped to the narrowest disease interval by STS content and radiation hybrid mapping. Thirteen glaucoma patients were found to have one of three mutations in this gene (3.9 percent of the population studied). One of these mutations was also found in a control individual (0.2 percent). Identification of these mutations will aid in early diagnosis, which is essential for optimal application of existing therapies.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Stone, E M -- Fingert, J H -- Alward, W L -- Nguyen, T D -- Polansky, J R -- Sunden, S L -- Nishimura, D -- Clark, A F -- Nystuen, A -- Nichols, B E -- Mackey, D A -- Ritch, R -- Kalenak, J W -- Craven, E R -- Sheffield, V C -- EY02477/EY/NEI NIH HHS/ -- EY08905/EY/NEI NIH HHS/ -- EY10564/EY/NEI NIH HHS/ -- etc. -- New York, N.Y. -- Science. 1997 Jan 31;275(5300):668-70.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Ophthalmology, University of Iowa College of Medicine, Iowa City, IA 52242, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/9005853" target="_blank"〉PubMed〈/a〉

    Description: An integrated human-mouse positional candidate approach was used to identify the gene responsible for the phenotypes observed in a mouse model of Niemann-Pick type C (NP-C) disease. The predicted murine NPC1 protein has sequence homology to the putative transmembrane domains of the Hedgehog signaling molecule Patched, to the cholesterol-sensing regions of 3-hydroxy-3-methylglutaryl coenzyme A (HMG-CoA) reductase and SREBP cleavage-activating protein (SCAP), and to the NPC1 orthologs identified in human, the nematode Caenorhabditis elegans, and the yeast Saccharomyces cerevisiae. The mouse model may provide an important resource for studying the role of NPC1 in cholesterol homeostasis and neurodegeneration and for assessing the efficacy of new drugs for NP-C disease.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Loftus, S K -- Morris, J A -- Carstea, E D -- Gu, J Z -- Cummings, C -- Brown, A -- Ellison, J -- Ohno, K -- Rosenfeld, M A -- Tagle, D A -- Pentchev, P G -- Pavan, W J -- New York, N.Y. -- Science. 1997 Jul 11;277(5323):232-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Laboratory of Genetic Disease Research, National Human Genome Research Institute, National Institutes of Health (NIH), Bethesda, MD 20892, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/9211850" target="_blank"〉PubMed〈/a〉

    Description: During translation errors of aminoacylation are corrected in editing reactions which ensure that an amino acid is stably attached to its corresponding transfer RNA (tRNA). Previous studies have not shown whether the tRNA nucleotides needed for effecting translational editing are the same as or distinct from those required for aminoacylation, but several considerations have suggested that they are the same. Here, designed tRNAs that are highly active for aminoacylation but are not active in translational editing are presented. The editing reaction can be controlled by manipulation of nucleotides at the corner of the L-shaped tRNA. In contrast, these manipulations do not affect aminoacylation. These results demonstrate the segregation of nucleotide determinants for the editing and aminoacylation functions of tRNA.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hale, S P -- Auld, D S -- Schmidt, E -- Schimmel, P -- GM15539/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1997 May 23;276(5316):1250-2.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biology, Massachusetts Institute of Technology, Cambridge, MA 02139, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/9157882" target="_blank"〉PubMed〈/a〉

    Description: Pathogenic Yersinia species have a specialized secretion system (type III) to target cytotoxic Yop proteins during infection. The signals of YopE and YopN sufficient for the secretion of translational reporter fusions were mapped to the first 15 codons. No common amino acid or peptide sequence could be identified among the secretion signals. Systematic mutagenesis of the secretion signal yielded mutants defective in Yop translation; however, no point mutants could be identified that specifically abolished secretion. Frameshift mutations that completely altered the peptide sequences of these signals also failed to prevent secretion. Thus, the signal that leads to the type III secretion of Yop proteins appears to be encoded in their messenger RNA rather than the peptide sequence.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Anderson, D M -- Schneewind, O -- AI 07323/AI/NIAID NIH HHS/ -- New York, N.Y. -- Science. 1997 Nov 7;278(5340):1140-3.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Microbiology and Immunology, Molecular Biology Institute, University of California, Los Angeles, School of Medicine, 10833 Le Conte Avenue, Los Angeles, CA 90095, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/9353199" target="_blank"〉PubMed〈/a〉

    Description: The gene responsible for autosomal dominant, fully penetrant, nonsyndromic sensorineural progressive hearing loss in a large Costa Rican kindred was previously localized to chromosome 5q31 and named DFNA1. Deafness in the family is associated with a protein-truncating mutation in a human homolog of the Drosophila gene diaphanous. The truncation is caused by a single nucleotide substitution in a splice donor, leading to a four-base pair insertion in messenger RNA and a frameshift. The diaphanous protein is a profilin ligand and target of Rho that regulates polymerization of actin, the major component of the cytoskeleton of hair cells of the inner ear.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lynch, E D -- Lee, M K -- Morrow, J E -- Welcsh, P L -- Leon, P E -- King, M C -- R01-DC01076/DC/NIDCD NIH HHS/ -- New York, N.Y. -- Science. 1997 Nov 14;278(5341):1315-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Medicine, University of Washington, Seattle, WA 98195, USA. eric@lynch.com〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/9360932" target="_blank"〉PubMed〈/a〉

    Description: The Janus family of tyrosine kinases (JAK) plays an essential role in development and in coupling cytokine receptors to downstream intracellular signaling events. A t(9;12)(p24;p13) chromosomal translocation in a T cell childhood acute lymphoblastic leukemia patient was characterized and shown to fuse the 3' portion of JAK2 to the 5' region of TEL, a gene encoding a member of the ETS transcription factor family. The TEL-JAK2 fusion protein includes the catalytic domain of JAK2 and the TEL-specific oligomerization domain. TEL-induced oligomerization of TEL-JAK2 resulted in the constitutive activation of its tyrosine kinase activity and conferred cytokine-independent proliferation to the interleukin-3-dependent Ba/F3 hematopoietic cell line.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lacronique, V -- Boureux, A -- Valle, V D -- Poirel, H -- Quang, C T -- Mauchauffe, M -- Berthou, C -- Lessard, M -- Berger, R -- Ghysdael, J -- Bernard, O A -- New York, N.Y. -- Science. 1997 Nov 14;278(5341):1309-12.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉U 301 de l'Institut National de la Sante et de la Recherche Medicale and SD 401 No. 301 CNRS, Institut de Genetique Moleculaire, 27 rue Juliette Dodu, 75010 Paris, France.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/9360930" target="_blank"〉PubMed〈/a〉

    Description: The extent of terrestrial vertebrate extinctions at the end of the Cretaceous is poorly understood, and estimates have ranged from a mass extinction to limited extinctions of specific groups. Molecular and paleontological data demonstrate that modern bird orders started diverging in the Early Cretaceous; at least 22 avian lineages of modern birds cross the Cretaceous-Tertiary boundary. Data for several other terrestrial vertebrate groups indicate a similar pattern of survival and, taken together, favor incremental changes during a Cretaceous diversification of birds and mammals rather than an explosive radiation in the Early Tertiary.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Cooper, A -- Penny, D -- New York, N.Y. -- Science. 1997 Feb 21;275(5303):1109-13.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉School of Biological Sciences, Victoria University of Wellington, Wellington, New Zealand. alan.cooper@bioanth.ox.ac.uk〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/9027308" target="_blank"〉PubMed〈/a〉

    Description: The molecular mechanisms that link cell-cycle controls to the mitotic apparatus are poorly understood. A component of the Saccharomyces cerevisiae spindle, Ase1, was observed to undergo cell cycle-specific degradation mediated by the cyclosome, or anaphase promoting complex (APC). Ase1 was degraded when cells exited from mitosis and entered G1. Inappropriate expression of stable Ase1 during G1 produced a spindle defect that is sensed by the spindle assembly checkpoint. In addition, loss of ASE1 function destabilized telophase spindles, and expression of a nondegradable Ase1 mutant delayed spindle disassembly. APC-mediated proteolysis therefore appears to regulate both spindle assembly and disassembly.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Juang, Y L -- Huang, J -- Peters, J M -- McLaughlin, M E -- Tai, C Y -- Pellman, D -- New York, N.Y. -- Science. 1997 Feb 28;275(5304):1311-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Pediatric Oncology, The Dana-Farber Cancer Institute, Harvard Medical School, Boston, MA 02115, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/9036857" target="_blank"〉PubMed〈/a〉
