    Glutamate receptor RNA editing in vitro by enzymatic conversion of adenosine to inosine (1995)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1995-03-10
    Description: RNA encoding the B subunit of the alpha-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid (AMPA) subtype of ionotropic glutamate receptor (GluR-B) undergoes a posttranscriptional modification in which a genomically encoded adenosine is represented as a guanosine in the GluR-B complementary DNA. In vitro editing of GluR-B RNA transcripts with HeLa cell nuclear extracts was found to result from an activity that converts adenosine to inosine in regions of double-stranded RNA by enzymatic base modification. This activity is consistent with that of a double-stranded RNA-specific adenosine deaminase previously described in Xenopus oocytes and widely distributed in mammalian tissues.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Rueter, S M -- Burns, C M -- Coode, S A -- Mookherjee, P -- Emeson, R B -- ES00267/ES/NIEHS NIH HHS/ -- New York, N.Y. -- Science. 1995 Mar 10;267(5203):1491-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Pharmacology, Vanderbilt University School of Medicine, Nashville, TN 37232-6600.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7878468" target="_blank"〉PubMed〈/a〉

    Regulation of TCR signaling by CD45 lacking transmembrane and extracellular domains (1993)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1993-04-23
    Description: The CD45 protein is a transmembrane tyrosine phosphatase that is required for normal T cell receptor (TCR)-mediated signaling. A chimeric complementary DNA encoding the intracellular enzymatically active portion of murine CD45 preceded by a short amino-terminal sequence from p60c-src was transfected into CD45- T cells. Expression of this chimeric protein corrected most of the TCR signaling abnormalities observed in the absence of CD45, including TCR-mediated enhancement of tyrosine kinase activity and Ca2+ flux. Thus, the enzymatically active intracellular portion of CD45 is sufficient to allow TCR transmembrane signaling.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Volarevic, S -- Niklinska, B B -- Burns, C M -- June, C H -- Weissman, A M -- Ashwell, J D -- New York, N.Y. -- Science. 1993 Apr 23;260(5107):541-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Laboratory of Immune Cell Biology, National Cancer Institute, National Institutes of Health, Bethesda, MD 20892.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8475386" target="_blank"〉PubMed〈/a〉
