    Alpha 2-antiplasmin Enschede: alanine insertion and abolition of plasmin inhibitory activity (1987)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1987-10-09
    Beschreibung: An abnormal alpha 2-antiplasmin that is associated with a serious bleeding tendency has been found in a Dutch family and is referred to as alpha 2-antiplasmin Enschede. This abnormal alpha 2-antiplasmin is converted from an inhibitor of plasmin to a substrate. The molecular defect of alpha 2-antiplasmin Enschede, as revealed by sequencing of cloned genomic DNA fragments, consists of an alanine insertion near the active site region of the molecule. Substitution of this fragment into complementary DNA for a wild-type alpha 2-antiplasmin yields a translation product with physical and functional properties typical of the abnormal alpha 2-antiplasmin Enschede. The naturally occurring mutant may serve as a model for investigating the structures that determine the properties of an inhibitor versus those of a substrate in serine protease inhibitors.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Holmes, W E -- Lijnen, H R -- Nelles, L -- Kluft, C -- Nieuwenhuis, H K -- Rijken, D C -- Collen, D -- New York, N.Y. -- Science. 1987 Oct 9;238(4824):209-11.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Center for Thrombosis and Vascular Research, University of Leuven, Belgium.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2958938" target="_blank"〉PubMed〈/a〉

    A novel putative tyrosine kinase receptor encoded by the eph gene (1987)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1987-12-18
    Beschreibung: Growth factors and their receptors are involved in the regulation of cell proliferation and also play a key role in oncogenesis. In this study, a novel putative kinase receptor gene, termed eph, has been identified and characterized by molecular cloning. Its primary structure is similar to that of tyrosine kinase receptors thus far cloned and includes a cysteine-rich region in the extracellular domain. However, other features of the sequence distinguish the eph gene product from known receptors with tyrosine kinase activity. Thus the eph protein may define a new class of these molecules. The eph gene is overexpressed in several human carcinomas, suggesting that this gene may be involved in the neoplastic process of some tumors.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hirai, H -- Maru, Y -- Hagiwara, K -- Nishida, J -- Takaku, F -- New York, N.Y. -- Science. 1987 Dec 18;238(4834):1717-20.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Third Department of Internal Medicine, Faculty of Medicine, University of Tokyo, Japan.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2825356" target="_blank"〉PubMed〈/a〉

    Conservation of the Duchenne muscular dystrophy gene in mice and humans (1987)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1987-10-16
    Beschreibung: A portion of the Duchenne muscular dystrophy (DMD) gene transcript from human fetal skeletal muscle and mouse adult heart was sequenced, representing approximately 25 percent of the total, 14-kb DMD transcript. The nucleic acid and predicted amino acid sequences from the two species are nearly 90 percent homologous. The amino acid sequence that is predicted from this portion of the DMD gene indicates that the protein product might serve a structural role in muscle, but the abundance and tissue distribution of the messenger RNA suggests that the DMD protein is not nebulin.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hoffman, E P -- Monaco, A P -- Feener, C C -- Kunkel, L M -- 2T 32 GM07753-07/GM/NIGMS NIH HHS/ -- HD18658/HD/NICHD NIH HHS/ -- R01 NS23740/NS/NINDS NIH HHS/ -- T32 GM007753/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1987 Oct 16;238(4825):347-50.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Division of Genetics, Children's Hospital, Boston, MA 02115.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3659917" target="_blank"〉PubMed〈/a〉

    D-alanine in the frog skin peptide dermorphin is derived from L-alanine in the precursor (1987)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1987-10-09
    Beschreibung: A D-alanine-containing peptide termed dermorphin, with potent opiate-like activity, has been isolated from skin of the frog Phyllomedusa sauvagei. Complementary DNA (cDNA) libraries were constructed from frog skin messenger RNA and screened with a mixture of oligonucleotides that contained the codons complementary to five amino acids of dermorphin. Clones were detected with inserts coding for different dermorphin precursors. The predicted amino acid sequences of these precursors contained homologous repeats of 35 amino acids that included one copy of the heptapeptide dermorphin. In these cloned cDNAs, the alanine codon GCG occurred at the position where D-alanine is present in the end product. This suggests the existence of a novel post-translational reaction for the conversion of an L-amino acid to its D-isomer.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Richter, K -- Egger, R -- Kreil, G -- New York, N.Y. -- Science. 1987 Oct 9;238(4824):200-2.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Molecular Biology Institute, Austrian Academy of Sciences, Salzburg.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3659910" target="_blank"〉PubMed〈/a〉

    Dorsal, an embryonic polarity gene in Drosophila, is homologous to the vertebrate proto-oncogene, c-rel (1987)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1987-10-30
    Beschreibung: The Drosophila gene, dorsal, is a maternal effect locus that is essential for the establishment of dorsal-ventral polarity in the developing embryo. The dorsal protein was predicted from the complementary DNA sequence; it is almost 50 percent identical, over an extensive region, to the protein encoded by the avian oncogene v-rel, its cellular homolog, c-rel, and a human c-rel fragment. The oncogene v-rel is highly oncogenic in avian lymphoid, spleen, and bone marrow cells.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Steward, R -- New York, N.Y. -- Science. 1987 Oct 30;238(4827):692-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biology, Princeton University, NJ 08544.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3118464" target="_blank"〉PubMed〈/a〉

    Apolipoprotein B-48 is the product of a messenger RNA with an organ-specific in-frame stop codon (1987)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1987-10-16
    Beschreibung: The primary structure of human apolipoprotein (apo) B-48 has been deduced and shown by a combination of DNA excess hybridization, sequencing of tryptic peptides, cloned complementary DNAs, and intestinal messenger RNAs (mRNAs) to be the product of an intestinal mRNA with an in-frame UAA stop codon resulting from a C to U change in the codon CAA encoding Gln2153 in apoB-100 mRNA. The carboxyl-terminal Ile2152 of apoB-48 purified from chylous ascites fluid has apparently been cleaved from the initial translation product, leaving Met2151 as the new carboxyl-terminus. These data indicate that approximately 85% of the intestinal mRNAs terminate within approximately 0.1 to 1.0 kilobase downstream from the stop codon. The other approximately 15% have lengths similar to hepatic apoB-100 mRNA even though they have the same in-frame stop codon. The organ-specific introduction of a stop codon to a mRNA appears unprecedented and might have implications for cryptic polyadenylation signal recognition and RNA processing.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Chen, S H -- Habib, G -- Yang, C Y -- Gu, Z W -- Lee, B R -- Weng, S A -- Silberman, S R -- Cai, S J -- Deslypere, J P -- Rosseneu, M -- GM-30998/GM/NIGMS NIH HHS/ -- HL-27341/HL/NHLBI NIH HHS/ -- New York, N.Y. -- Science. 1987 Oct 16;238(4825):363-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Cell Biology, Baylor College of Medicine, Houston, TX 77030.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3659919" target="_blank"〉PubMed〈/a〉

    Identification of the iron-responsive element for the translational regulation of human ferritin mRNA (1987)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1987-12-11
    Beschreibung: Regulated translation of messenger RNA offers an important mechanism for the control of gene expression. The biosynthesis of the intracellular iron storage protein ferritin is translationally regulated by iron. A cis-acting element that is both necessary and sufficient for this translational regulation is present within the 5' nontranslated leader region of the human ferritin H-chain messenger RNA. In this report the iron-responsive element (IRE) was identified by deletional analysis. Moreover, a synthetic oligodeoxynucleotide was shown to be able to transfer iron regulation to a construct that would otherwise not be able to respond to iron. The IRE has been highly conserved and predates the evolutionary segregation between amphibians, birds, and man. The IRE may prove to be useful for the design of translationally regulated expression systems.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hentze, M W -- Caughman, S W -- Rouault, T A -- Barriocanal, J G -- Dancis, A -- Harford, J B -- Klausner, R D -- New York, N.Y. -- Science. 1987 Dec 11;238(4833):1570-3.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Cell Biology and Metabolism Branch, National Institute of Child Health and Human Development, Bethesda, MD 20892.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3685996" target="_blank"〉PubMed〈/a〉

    Bacteriophage M13 procoat protein inserts into the plasma membrane as a loop structure (1987)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1987-12-04
    Beschreibung: The major coat protein of bacteriophage M13 is synthesized as a precursor, the procoat, with a typical leader (signal) sequence of 23 residues at its NH2-terminus. A fusion protein that contains the NH2-terminal 141 residues of cytoplasmic ribulokinase and all but the first ten residues of M13 procoat was made. The fusion protein inserts into the plasma membrane of Escherichia coli and is processed by leader peptidase to give rise to a leader peptide of 155 residues and the mature coat protein of 50 residues. The NH2-terminus of the leader peptide remains in the cytoplasm and is protected from protease added to the medium outside of the cell. This indicates that M13 procoat inserts into the membrane as a loop structure and that the NH2-terminus of a leader peptide remains within the cytoplasm during membrane insertion.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kuhn, A -- New York, N.Y. -- Science. 1987 Dec 4;238(4832):1413-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Microbiology Department, University of Basel, Switzerland.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3317833" target="_blank"〉PubMed〈/a〉

    Early restriction of the human antibody repertoire (1987)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1987-11-06
    Beschreibung: Diversification of the antibody repertoire in mammals results from a series of apparently random somatically propagated gene rearrangement and mutational events. Nevertheless, it is well known that the adult repertoire of antibody specificities is acquired in a developmentally programmed fashion. As previously shown, rearrangement of the gene segments encoding the heavy-chain variable regions (VH) of mouse antibodies is also developmentally ordered: the number of VH gene segments rearranged in B lymphocytes of fetal mice is small but increased progressively after birth. In this report, human fetal B-lineage cells were also shown to rearrange a highly restricted set of VH gene segments. In a sample of heavy-chain transcripts from a 130-day human fetus the most frequently expressed human VH element proved to be closely related to the VH element most frequently expressed in murine fetal B-lineage cells. These observations are important in understanding the development of immunocompetence.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Schroeder, H W Jr -- Hillson, J L -- Perlmutter, R M -- AI07470/AI/NIAID NIH HHS/ -- GM07454/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1987 Nov 6;238(4828):791-3.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Howard Hughes Medical Institute, University of Washington, Seattle 98195.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3118465" target="_blank"〉PubMed〈/a〉

    A synaptic vesicle protein with a novel cytoplasmic domain and four transmembrane regions (1987)

    Details
    Publikationsdatum: 1987-11-20
    Beschreibung: Complementary DNA and genomic clones were isolated and sequenced corresponding to rat and human synaptophysin (p38), a major integral membrane protein of synaptic vesicles. The deduced amino acid sequences indicate an evolutionarily highly conserved protein that spans the membrane four times. Both amino and carboxyl termini face the cytoplasm, with the latter containing ten copies of a tyrosine-rich pentapeptide repeat. The structure of synaptophysin suggests that the protein may function as a channel in the synaptic vesicle membrane, with the carboxyl terminus serving as a binding site for cellular factors.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Sudhof, T C -- Lottspeich, F -- Greengard, P -- Mehl, E -- Jahn, R -- New York, N.Y. -- Science. 1987 Nov 20;238(4830):1142-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Howard Hughes Medical Institute, Department of Molecular Genetics, University of Texas Health Science Center, Dallas 75235.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3120313" target="_blank"〉PubMed〈/a〉
