    Beschreibung: The metabotropic glutamate receptors (mGluRs) are widely distributed in the brain and play important roles in synaptic plasticity. Here it is shown that some types of mGluRs are activated not only by glutamate but also by extracellular Ca2+ (Ca2+o). A single amino acid residue was found to determine the sensitivity of mGluRs to Ca2+o. One of the receptors, mGluR1alpha, but not its point mutant with reduced sensitivity to Ca2+o, caused morphological changes when transfected into mammalian cells. Thus, the sensing of Ca2+o by mGluRs may be important in cells under physiological condition.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kubo, Y -- Miyashita, T -- Murata, Y -- New York, N.Y. -- Science. 1998 Mar 13;279(5357):1722-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Neurophysiology, Tokyo Metropolitan Institute for Neuroscience, Musashidai 2-6, Fuchu, Tokyo 183-8526, Japan. ykubo@tmin.ac.jp〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/9497291" target="_blank"〉PubMed〈/a〉

    Beschreibung: A peripheral membrane protein that is interactive with lymphocytic choriomeningitis virus (LCMV) was purified from cells permissive to infection. Tryptic peptides from this protein were determined to be alpha-dystroglycan (alpha-DG). Several strains of LCMV and other arenaviruses, including Lassa fever virus (LFV), Oliveros, and Mobala, bound to purified alpha-DG protein. Soluble alpha-DG blocked both LCMV and LFV infection. Cells bearing a null mutation of the gene encoding DG were resistant to LCMV infection, and reconstitution of DG expression in null mutant cells restored susceptibility to LCMV infection. Thus, alpha-DG is a cellular receptor for both LCMV and LFV.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Cao, W -- Henry, M D -- Borrow, P -- Yamada, H -- Elder, J H -- Ravkov, E V -- Nichol, S T -- Compans, R W -- Campbell, K P -- Oldstone, M B -- AG 00080/AG/NIA NIH HHS/ -- AI 09484/AI/NIAID NIH HHS/ -- DK09712/DK/NIDDK NIH HHS/ -- etc. -- New York, N.Y. -- Science. 1998 Dec 11;282(5396):2079-81.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Division of Virology, Department of Neuropharmacology, The Scripps Research Institute, 10550 North Torrey Pines Road, La Jolla, CA 92037, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/9851928" target="_blank"〉PubMed〈/a〉

    Beschreibung: After the vertebrate lens is induced from head ectoderm, lens-specific genes are expressed. Transcriptional regulation of the lens-specific alphaA-crystallin gene is controlled by an enhancer element, alphaCE2. A gene encoding an alphaCE2-binding protein, L-maf(lens-specific maf), was isolated. L-maf expression is initiated in the lens placode and is restricted to lens cells. The gene product L-Maf regulates the expression of multiple genes expressed in the lens, and ectopic expression of this transcription factor converts chick embryonic ectodermal cells and cultured cells into lens fibers. Thus, vertebrate lens induction and differentiation can be triggered by the activation of L-Maf.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Ogino, H -- Yasuda, K -- New York, N.Y. -- Science. 1998 Apr 3;280(5360):115-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Graduate School of Biological Sciences, Nara Institute of Science and Technology, 8916-5 Takayama, Ikoma 630-0101, Japan.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/9525857" target="_blank"〉PubMed〈/a〉

    Beschreibung: Mice homozygous for a disrupted allele of the mismatch repair gene Pms2 have a mutator phenotype. When this allele is crossed into quasi-monoclonal (QM) mice, which have a very limited B cell repertoire, homozygotes have fewer somatic mutations at the immunoglobulin heavy chain and lambda chain loci than do heterozygotes or wild-type QM mice. That is, mismatch repair seems to contribute to somatic hypermutation rather than stifling it. It is suggested that at immunoglobulin loci in hypermutable B cells, mismatched base pairs are "corrected" according to the newly synthesized DNA strand, thereby fixing incipient mutations instead of eliminating them.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Cascalho, M -- Wong, J -- Steinberg, C -- Wabl, M -- 1R01 GM37699/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1998 Feb 20;279(5354):1207-10.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Microbiology and Immunology, University of California, San Francisco, CA 94143-0670, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/9469811" target="_blank"〉PubMed〈/a〉

    Beschreibung: The 2.5 angstrom resolution x-ray crystal structure of the Escherichia coli RNA polymerase (RNAP) alpha subunit amino-terminal domain (alphaNTD), which is necessary and sufficient to dimerize and assemble the other RNAP subunits into a transcriptionally active enzyme and contains all of the sequence elements conserved among eukaryotic alpha homologs, has been determined. The alphaNTD monomer comprises two distinct, flexibly linked domains, only one of which participates in the dimer interface. In the alphaNTD dimer, a pair of helices from one monomer interact with the cognate helices of the other to form an extensive hydrophobic core. All of the determinants for interactions with the other RNAP subunits lie on one face of the alphaNTD dimer. Sequence alignments, combined with secondary-structure predictions, support proposals that a heterodimer of the eukaryotic RNAP subunits related to Saccharomyces cerevisiae Rpb3 and Rpb11 plays the role of the alphaNTD dimer in prokaryotic RNAP.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Zhang, G -- Darst, S A -- GM19441-01/GM/NIGMS NIH HHS/ -- GM53759/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1998 Jul 10;281(5374):262-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Rockefeller University, 1230 York Avenue, New York, NY 10021, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/9657722" target="_blank"〉PubMed〈/a〉

    Beschreibung: In the adult mouse, single and compound null mutations in the genes for retinoic acid receptor beta and retinoid X receptors beta and gamma resulted in locomotor defects related to dysfunction of the mesolimbic dopamine signaling pathway. Expression of the D1 and D2 receptors for dopamine was reduced in the ventral striatum of mutant mice, and the response of double null mutant mice to cocaine, which affects dopamine signaling in the mesolimbic system, was blunted. Thus, retinoid receptors are involved in the regulation of brain functions, and retinoic acid signaling defects may contribute to pathologies such as Parkinson's disease and schizophrenia.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Krezel, W -- Ghyselinck, N -- Samad, T A -- Dupe, V -- Kastner, P -- Borrelli, E -- Chambon, P -- New York, N.Y. -- Science. 1998 Feb 6;279(5352):863-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Institut de Genetique et de Biologie Moleculaire et Cellulaire, CNRS, INSERM, Universite Louis Pasteur, College de France, Boite Postale 163, 67404 Illkirch Cedex, France.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/9452386" target="_blank"〉PubMed〈/a〉

    Beschreibung: Dipterous insects (the true flies) have a sophisticated pair of equilibrium organs called halteres that evolved from hind wings. The halteres are sensitive to Coriolis forces that result from angular rotations of the body and mediate corrective reflexes during flight. Like the aerodynamically functional fore wings, the halteres beat during flight and are equipped with their own set of control muscles. It is shown that motoneurons innervating muscles of the haltere receive strong excitatory input from directionally sensitive visual interneurons. Visually guided flight maneuvers of flies may be mediated in part by efferent modulation of hard-wired equilibrium reflexes.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Chan, W P -- Prete, F -- Dickinson, M H -- New York, N.Y. -- Science. 1998 Apr 10;280(5361):289-92.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Integrative Biology, University of California, Berkeley, CA 94720, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/9535659" target="_blank"〉PubMed〈/a〉

    Beschreibung: FADD (also known as Mort-1) is a signal transducer downstream of cell death receptor CD95 (also called Fas). CD95, tumor necrosis factor receptor type 1 (TNFR-1), and death receptor 3 (DR3) did not induce apoptosis in FADD-deficient embryonic fibroblasts, whereas DR4, oncogenes E1A and c-myc, and chemotherapeutic agent adriamycin did. Mice with a deletion in the FADD gene did not survive beyond day 11.5 of embryogenesis; these mice showed signs of cardiac failure and abdominal hemorrhage. Chimeric embryos showing a high contribution of FADD null mutant cells to the heart reproduce the phenotype of FADD-deficient mutants. Thus, not only death receptors, but also receptors that couple to developmental programs, may use FADD for signaling.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Yeh, W C -- de la Pompa, J L -- McCurrach, M E -- Shu, H B -- Elia, A J -- Shahinian, A -- Ng, M -- Wakeham, A -- Khoo, W -- Mitchell, K -- El-Deiry, W S -- Lowe, S W -- Goeddel, D V -- Mak, T W -- CA13106/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 1998 Mar 20;279(5358):1954-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Amgen Institute, University of Toronto, Toronto, Ontario, Canada.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/9506948" target="_blank"〉PubMed〈/a〉
