    Peptide processing and targeting in the neuronal secretory pathway (1991)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1991-03-15
    Description: The abdominal ganglion of the marine mollusk Aplysia contains a pair of identified neuronal clusters, the bag cells, which control egg laying by means of a number of unique regulatory mechanisms. Each neuron in the bag cell clusters synthesizes several peptides derived from a single prohormone and packages them into separate vesicles. These vesicles are then differentially localized in specific neuronal processes, thus segregating peptides destined for autocrine and hormonal release sites. Therefore in this system, protein trafficking through the secretory pathway organizes multiple peptide neurochemical messengers to efficiently regulate simple behaviors.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Jung, L J -- Scheller, R H -- New York, N.Y. -- Science. 1991 Mar 15;251(4999):1330-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Howard Hughes Medical Institute, Department of Molecular and Cellular Physiology, Beckman Center, Stanford University, CA 94305.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2003219" target="_blank"〉PubMed〈/a〉

    Identification of the DNA binding site for NGFI-B by genetic selection in yeast (1991)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1991-05-31
    Description: An in vivo selection system for isolating targets of DNA binding proteins in yeast was developed and used to identify the DNA binding site for the NGFI-B protein, a member of the steroid-thyroid hormone receptor superfamily. The feasibility of the technique was verified by selecting DNA fragments that contained binding sites for GCN4, a well-characterized yeast transcriptional activator. The DNA binding domain of NGFI-B, expressed as part of a LexA-NGFI-B-GAL4 chimeric activator, was then used to isolate a rat genomic DNA fragment that contained an NGFI-B binding site. The NGFI-B response element (NBRE) is similar to but functionally distinct from elements recognized by the estrogen and thyroid hormone receptors and the hormone receptor-like proteins COUP-TF, CF1, and H-2RIIBP. Cotransfection experiments in mammalian cells demonstrated that NGFI-B can activate transcription from the NBRE with or without its putative ligand binding domain.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Wilson, T E -- Fahrner, T J -- Johnston, M -- Milbrandt, J -- NS01018/NS/NINDS NIH HHS/ -- P01 CA49712/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 1991 May 31;252(5010):1296-300.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Pathology, Washington University School of Medicine, St. Louis, MO 63110.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/1925541" target="_blank"〉PubMed〈/a〉

    Cloning and expression of a cocaine-sensitive rat dopamine transporter (1991)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1991-10-25
    Description: The action of dopamine and other monoamine neurotransmitters at synapses is terminated predominantly by high-affinity reuptake into presynaptic terminals by specific sodium-dependent neurotransmitter transport proteins. A complementary DNA encoding a rat dopamine transporter has been isolated that exhibits high sequence similarity with the previously cloned norepinephrine and gamma-aminobutyric acid transporters. Transient expression of the complementary DNA in HeLa cells confirms the cocaine sensitivity of this transporter.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kilty, J E -- Lorang, D -- Amara, S G -- New York, N.Y. -- Science. 1991 Oct 25;254(5031):578-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Yale University, New Haven, CT 06510.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/1948035" target="_blank"〉PubMed〈/a〉

    Exchange of conduction pathways between two related K+ channels (1991)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1991-02-22
    Description: The structure of the ion conduction pathway or pore of voltage-gated ion channels is unknown, although the linker between the membrane spanning segments S5 and S6 has been suggested to form part of the pore in potassium channels. To test whether this region controls potassium channel conduction, a 21-amino acid segment of the S5-S6 linker was transplanted from the voltage-activated potassium channel NGK2 to another potassium channel DRK1, which has very different pore properties. In the resulting chimeric channel, the single channel conductance and blockade by external and internal tetraethylammonium (TEA) ion were characteristic of the donor NGK2 channel. Thus, this 21-amino acid segment controls the essential biophysical properties of the pore and may form the conduction pathway of these potassium channels.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hartmann, H A -- Kirsch, G E -- Drewe, J A -- Taglialatela, M -- Joho, R H -- Brown, A M -- NS08805/NS/NINDS NIH HHS/ -- NS23877/NS/NINDS NIH HHS/ -- NS28407/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 1991 Feb 22;251(4996):942-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Molecular Physiology and Biophysics, Baylor College of Medicine, Houston, TX 77030.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2000495" target="_blank"〉PubMed〈/a〉

    Deregulation of a homeobox gene, HOX11, by the t(10;14) in T cell leukemia (1991)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1991-07-05
    Description: Molecular cloning of the t(10;14)(q24;q11) recurrent breakpoint of T cell acute lymphoblastic leukemia has demonstrated a transcript for the candidate gene TCL3. Characterization of this gene from chromosome segment 10q24 revealed it to be a new homeobox, HOX11. The HOX11 homeodomain is most similar to that of the murine gene Hlx and possesses a markedly glycine-rich variable region and an acidic carboxyl terminus. HOX11, while expressed in liver, was not detected in normal thymus or T cells. This lineage-restricted homeobox gene is deregulated upon translocation into the T cell receptor locus where it may act as an oncogene.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hatano, M -- Roberts, C W -- Minden, M -- Crist, W M -- Korsmeyer, S J -- 1 PO1 CA49712/CA/NCI NIH HHS/ -- CA 21765/CA/NCI NIH HHS/ -- CA 30969/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 1991 Jul 5;253(5015):79-82.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Howard Hughes Medical Institute, Washington University School of Medicine, St. Louis, MO 63110.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/1676542" target="_blank"〉PubMed〈/a〉

    Selective activation of the B natriuretic peptide receptor by C-type natriuretic peptide (CNP) (1991)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1991-04-05
    Description: The natriuretic peptides are hormones that can stimulate natriuretic, diuretic, and vasorelaxant activity in vivo, presumably through the activation of two known cell surface receptor guanylyl cyclases (ANPR-A and ANPR-B). Although atrial natriuretic peptide (ANP) and, to a lesser extent, brain natriuretic peptide (BNP) are efficient activators of the ANPR-A guanylyl cyclase, neither hormone can significantly stimulate ANPR-B. A member of this hormone family, C-type natriuretic peptide (CNP), potently and selectively activated the human ANPR-B guanylyl cyclase. CNP does not increase guanosine 3',5'-monophosphate accumulation in cells expressing human ANPR-A. The affinity of CNP for ANPR-B is 50- or 500-fold higher than ANP or BNP, respectively. This ligand-receptor pair may be involved in the regulation of fluid homeostasis by the central nervous system.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Koller, K J -- Lowe, D G -- Bennett, G L -- Minamino, N -- Kangawa, K -- Matsuo, H -- Goeddel, D V -- New York, N.Y. -- Science. 1991 Apr 5;252(5002):120-3.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Molecular Biology, Genentech, Inc., South San Francisco 94080.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/1672777" target="_blank"〉PubMed〈/a〉

    Details
    Publication Date: 1991-10-18
    Description: Dioxin (2,3,7,8-tetrachlorodibenzo-p-dioxin, TCDD), a widespread environmental contaminant, may elicit its effects by altering gene expression in susceptible cells. Five TCDD-responsive complementary DNA clones were isolated from a human keratinocyte cell line. One of these clones encodes plasminogen activator inhibitor-2, a factor that influences growth and differentiation by regulating proteolysis of the extracellular matrix. Another encodes the cytokine interleukin-1 beta. Thus, TCDD alters the expression of growth regulatory genes and has effects similar to those of other tumor-promoting agents that affect both inflammation and differentiation.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Sutter, T R -- Guzman, K -- Dold, K M -- Greenlee, W F -- New York, N.Y. -- Science. 1991 Oct 18;254(5030):415-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Chemical Industry Institute of Toxicology, Research Triangle Park, NC 27709.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/1925598" target="_blank"〉PubMed〈/a〉

    Cloning of a factor required for activity of the Ah (dioxin) receptor (1991)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1991-05-17
    Description: The aryl hydrocarbon (Ah) receptor binds various environmental pollutants, such as polycyclic aromatic hydrocarbons, heterocyclic amines, and polychlorinated aromatic compounds (dioxins, dibenzofurans, and biphenyls), and mediates the carcinogenic effects of these agents. The complementary DNA and part of the gene for an 87-kilodalton human protein that is necessary for Ah receptor function have been cloned. The protein is not the ligand-binding subunit of the receptor but is a factor that is required for the ligand-binding subunit to translocate from the cytosol to the nucleus after binding ligand. The requirement for this factor distinguishes the Ah receptor from the glucocorticoid receptor, to which the Ah receptor has been presumed to be similar. Two portions of the 87-kilodalton protein share sequence similarities with two Drosophila proteins, Per and Sim. Another segment of the protein shows conformity to the consensus sequence for the basic helix-loop-helix motif found in proteins that bind DNA as homodimers or heterodimers.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hoffman, E C -- Reyes, H -- Chu, F F -- Sander, F -- Conley, L H -- Brooks, B A -- Hankinson, O -- CA 16048/CA/NCI NIH HHS/ -- CA 28868/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 1991 May 17;252(5008):954-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Pathology, University of California, Los Angeles 90024.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/1852076" target="_blank"〉PubMed〈/a〉

    Regulation of the apolipoprotein AI gene by ARP-1, a novel member of the steroid receptor superfamily (1991)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1991-02-01
    Description: Apolipoprotein AI (apoAI) is a lipid-binding protein that participates in the transport of cholesterol and other lipids in the plasma. A complementary DNA clone for a protein that bound to regulatory elements of the apoAI gene was isolated. This protein, designated apoAI regulatory protein-1 (ARP-1), is a novel member of the steroid hormone receptor superfamily. ARP-1 bound to DNA as a dimer, and its dimerization domain was localized to the COOH-terminal region. ARP-1 also bound to a thyroid hormone-responsive element and to regulatory regions of the apoB, apoCIII, insulin, and ovalbumin genes. In cotransfection experiments, ARP-1 downregulated the apoAI gene. The involvement of ARP-1 in the regulation of apoAI gene expression suggests that it may participate in lipid metabolism and cholesterol homeostasis.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Ladias, J A -- Karathanasis, S K -- New York, N.Y. -- Science. 1991 Feb 1;251(4993):561-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Cardiology, Children's Hospital, Boston, MA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/1899293" target="_blank"〉PubMed〈/a〉

    Publication Date: 1991-08-16
    Description: Recombinant cDNA clones that encode two distinct subunits of the transcription factor GA binding protein (GABP) have been isolated. The predicted amino acid sequence of one subunit, GABP alpha, exhibits similarity to the sequence of the product of the ets-1 protooncogene in a region known to encompass the Ets DNA binding domain. The sequence of the second subunit, GABP beta, contains four 33-amino acid repeats located close to the NH2-terminus of the subunit. The sequences of these repeats are similar to repeats in several transmembrane proteins, including Notch from Drosophila melanogaster and Glp-1 and Lin-12 from Caenorhabditis elegans. Avid, sequence-specific binding to DNA required the presence of both polypeptides, revealing a conceptual convergence of nuclear transforming proteins and membrane-anchored proteins implicated in developmentally regulated signal transduction processes.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉LaMarco, K -- Thompson, C C -- Byers, B P -- Walton, E M -- McKnight, S L -- New York, N.Y. -- Science. 1991 Aug 16;253(5021):789-92.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Howard Hughes Research Laboratories, Carnegie Institution of Washington, Department of Embryology, Baltimore, MD 21210.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/1876836" target="_blank"〉PubMed〈/a〉

    A component of calcium-activated potassium channels encoded by the Drosophila slo locus (1991)

    Details
    Publication Date: 1991-08-02
    Description: Calcium-activated potassium channels mediate many biologically important functions in electrically excitable cells. Despite recent progress in the molecular analysis of voltage-activated K+ channels, Ca(2+)-activated K+ channels have not been similarly characterized. The Drosophila slowpoke (slo) locus, mutations of which specifically abolish a Ca(2+)-activated K+ current in muscles and neurons, provides an opportunity for molecular characterization of these channels. Genomic and complementary DNA clones from the slo locus were isolated and sequenced. The polypeptide predicted by slo is similar to voltage-activated K+ channel polypeptides in discrete domains known to be essential for function. Thus, these results indicate that slo encodes a structural component of Ca(2+)-activated K+ channels.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Atkinson, N S -- Robertson, G A -- Ganetzky, B -- NS15390/NS/NINDS NIH HHS/ -- T32 GM07131/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1991 Aug 2;253(5019):551-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Laboratory of Genetics, University of Wisconsin, Madison 53706.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/1857984" target="_blank"〉PubMed〈/a〉

    FTZ-F1, a steroid hormone receptor-like protein implicated in the activation of fushi tarazu (1991)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1991-05-10
    Description: The Drosophila homeobox segmentation gene fushi tarazu (ftz) is expressed in a seven-stripe pattern during early embryogenesis. This characteristic pattern is largely specified by the zebra element located immediately upstream of the ftz transcriptional start site. The FTZ-F1 protein, one of multiple DNA binding factors that interacts with the zebra element, is implicated in the activation of ftz transcription, especially in stripes 1, 2, 3, and 6. An FTZ-F1 complementary DNA has been cloned by recognition site screening of a Drosophila expression library. The identity of the FTZ-F1 complementary DNA clone was confirmed by immunological cross-reaction with antibodies to FTZ-F1 and by sequence analysis of peptides from purified FTZ-F1 protein. The predicted amino acid sequence of FTZ-F1 revealed that the protein is a member of the nuclear hormone receptor superfamily. This finding raises the possibility that a hormonal ligand affects the expression of a homeobox segmentation gene early in embryonic development.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lavorgna, G -- Ueda, H -- Clos, J -- Wu, C -- New York, N.Y. -- Science. 1991 May 10;252(5007):848-51.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Laboratory of Biochemistry, 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/1709303" target="_blank"〉PubMed〈/a〉

    Isolation of a rel-related human cDNA that potentially encodes the 65-kD subunit of NF-kappa B (1991)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1991-03-22
    Description: A DNA probe that spanned a domain conserved among the proto-oncogene c-rel, the Drosophila morphogen dorsal, and the p50 DNA binding subunit of NF-kappa B was generated from Jurkat T cell complementary DNA with the polymerase chain reaction (PCR) and degenerate oligonucleotides. This probe was used to identify a rel-related complementary DNA that hybridized to a 2.6-kilobase messenger RNA present in human T and B lymphocytes. In vitro transcription and translation of the complementary DNA resulted in the synthesis of a protein with an apparent molecular size of 65 kilodaltons (kD). The translated protein showed weak DNA binding with a specificity for the kappa B binding motif. This protein-DNA complex comigrated with the complex obtained with the purified human p65 NF-kappa B subunit and binding was inhibited by I kappa B-alpha and -beta proteins. In addition, the 65-kD protein associated with the p50 subunit of NF-kappa B and the kappa B probe to form a complex with the same electrophoretic mobility as the NF-kappa B-DNA complex. Therefore the rel-related 65-kD protein may represent the p65 subunit of the active NF-kappa B transcription factor complex.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Ruben, S M -- Dillon, P J -- Schreck, R -- Henkel, T -- Chen, C H -- Maher, M -- Baeuerle, P A -- Rosen, C A -- New York, N.Y. -- Science. 1991 Mar 22;251(5000):1490-3.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Molecular Oncology and Virology, Roche Institute of Molecular Biology, Roche Research Center, Nutley, NJ 07110-1199.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2006423" target="_blank"〉PubMed〈/a〉

    Expression cloning of an adenylate cyclase-coupled calcitonin receptor (1991)

    Details
    Publication Date: 1991-11-25
    Description: A calcitonin receptor complementary DNA (cDNA) was cloned by expression of a cDNA library from a porcine kidney epithelial cell line in COS cells. The 482-amino acid receptor has high affinity for salmon calcitonin (dissociation constant Kd approximately 6 nM) and is functionally coupled to increases in intracellular cyclic adenosine monophosphate (cAMP). The receptor shows no sequence similarity to other reported G protein-coupled receptors but is homologous to the parathyroid hormone-parathyroid hormone-related peptide (PTH-PTHrP) receptor, indicating that the receptors for these hormones, which regulate calcium homeostasis, represent a new family of G protein-coupled receptors.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lin, H Y -- Harris, T L -- Flannery, M S -- Aruffo, A -- Kaji, E H -- Gorn, A -- Kolakowski, L F Jr -- Lodish, H F -- Goldring, S R -- AM 03564/AM/NIADDK NIH HHS/ -- HL-41484/HL/NHLBI NIH HHS/ -- New York, N.Y. -- Science. 1991 Nov 15;254(5034):1022-4.〈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/1658940" target="_blank"〉PubMed〈/a〉

    Description: Onchocerciasis (river blindness) is a serious health problem and a severe obstacle to social and economic development, especially in Africa. A complementary DNA fragment coding for an Onchocerca volvulus antigen (OV-16) was cloned and expressed in the plasmid vector pCG808fx. Immune responses to this O. volvulus-specific recombinant antigen were detectable in patients with documented onchocerciasis; the antibody response was also detectable at 3 months and at more than 1 year before infection could otherwise be detected in humans and in chimpanzees experimentally infected with O. volvulus third-stage larvae.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lobos, E -- Weiss, N -- Karam, M -- Taylor, H R -- Ottesen, E A -- Nutman, T B -- New York, N.Y. -- Science. 1991 Mar 29;251(5001):1603-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Laboratory of Parasitic Diseases, National Institutes of Allergy and Infectious Diseases, National Institutes of Health, Bethesda, MD 20892.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2011741" target="_blank"〉PubMed〈/a〉

    Max: a helix-loop-helix zipper protein that forms a sequence-specific DNA-binding complex with Myc (1991)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1991-03-08
    Description: The myc protooncogene family has been implicated in cell proliferation, differentiation, and neoplasia, but its mechanism of function at the molecular level is unknown. The carboxyl terminus of Myc family proteins contains a basic region helix-loop-helix leucine zipper motif (bHLH-Zip), which has DNA-binding activity and has been predicted to mediate protein-protein interactions. The bHLH-Zip region of c-Myc was used to screen a complementary DNA (cDNA) expression library, and a bHLH-Zip protein, termed Max, was identified. Max specifically associated with c-Myc, N-Myc, and L-Myc proteins, but not with a number of other bHLH, bZip, or bHLH-Zip proteins. The interaction between Max and c-Myc was dependent on the integrity of the c-Myc HLH-Zip domain, but not on the basic region or other sequences outside the domain. Furthermore, the Myc-Max complex bound to DNA in a sequence-specific manner under conditions where neither Max nor Myc exhibited appreciable binding. The DNA-binding activity of the complex was dependent on both the dimerization domain and the basic region of c-Myc. These results suggest that Myc family proteins undergo a restricted set of interactions in the cell and may belong to the more general class of eukaryotic DNA-binding transcription factors.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Blackwood, E M -- Eisenman, R N -- P01 CA28151/CA/NCI NIH HHS/ -- R01 CA20525/CA/NCI NIH HHS/ -- T32 CA09437/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 1991 Mar 8;251(4998):1211-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Division of Basic Sciences, Fred Hutchinson Cancer Research Center, Seattle, WA 98104.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2006410" target="_blank"〉PubMed〈/a〉

    Suppression of the immune response by a soluble complement receptor of B lymphocytes (1991)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1991-10-04
    Description: The CD19-CR2 complex of B lymphocytes contains proteins that participate in two host-defense systems, the immune and complement systems. The ligand for the subunit of the immune system, CD19, is not known, but the complement receptor subunit, CR2 (CD21), binds activation fragments of the C3 component of the complement system and may mediate immunopotentiating effects of complement. A recombinant, soluble CR2 was prepared by fusing the C3-binding region of the receptor to immunoglobulin G1 (IgG1). The (CR2)2-IgG1 chimera competed with cellular CR2 for C3 binding and suppressed the antibody response to a T cell-dependent antigen when administered to mice at the time of immunization. This inhibitory effect of (CR2)2-IgG1 demonstrates the B cell-activating function of the CD19-CR2 complex and suggests a new method for humoral immunosuppression.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hebell, T -- Ahearn, J M -- Fearon, D T -- AI-22833/AI/NIAID NIH HHS/ -- AI-28191/AI/NIAID NIH HHS/ -- GM-43803/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1991 Oct 4;254(5028):102-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Medicine, Johns Hopkins University School of Medicine, Baltimore, MD 21205.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/1718035" target="_blank"〉PubMed〈/a〉

    Isolation of sequences that span the fragile X and identification of a fragile X-related CpG island (1991)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1991-03-08
    Description: Yeast artificial chromosomes (YACs) were obtained from a 550-kilobase region that contains three probes previously mapped as very close to the locus of the fragile X syndrome. These YACs spanned the fragile site in Xq27.3 as shown by fluorescent in situ hybridization. An internal 200-kilobase segment contained four chromosomal breakpoints generated by induction of fragile X expression. A single CpG island was identified in the cloned region between markers DXS463 and DXS465 that appears methylated in mentally retarded fragile X males, but not in nonexpressing male carriers of the mutation nor in normal males. This CpG island may indicate the presence of a gene involved in the clinical phenotype of the syndrome.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Heitz, D -- Rousseau, F -- Devys, D -- Saccone, S -- Abderrahim, H -- Le Paslier, D -- Cohen, D -- Vincent, A -- Toniolo, D -- Della Valle, G -- New York, N.Y. -- Science. 1991 Mar 8;251(4998):1236-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Laboratoire de Genetique Moleculaire des Eucaryotes du CNRS, Institut de Chimie Biologique, Faculte de Medecine, Strasbourg, France.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2006411" target="_blank"〉PubMed〈/a〉

    Type-specific regulation of adenylyl cyclase by G protein beta gamma subunits (1991)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1991-12-06
    Description: Heterotrimeric guanine nucleotide-binding regulatory proteins (G proteins) dissociate into guanosine triphosphate (GTP)-bound alpha subunits and a complex of beta and gamma subunits after interaction with receptors. The GTP-alpha subunit complex activates appropriate effectors, such as adenylyl cyclase, retinal phosphodiesterase, phospholipase C, and ion channels. G protein beta gamma subunits have been found to have regulatory effects on certain types of adenylyl cyclase. In the presence of Gs alpha, the alpha subunit of the G protein that activates adenylyl cyclase, one form of adenylyl cyclase was inhibited by beta gamma, some forms were activated by beta gamma, and some forms were not affected by beta gamma. These interactions suggest mechanisms for communication between distinct signal-transducing pathways.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Tang, W J -- Gilman, A G -- GM34497/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1991 Dec 6;254(5037):1500-3.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Pharmacology, University of Texas Southwestern Medical Center, Dallas 75235.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/1962211" target="_blank"〉PubMed〈/a〉

    Publication Date: 1991-10-04
    Description: LIV-I, a high-affinity system that transports neutral, branched-chain amino acids into Escherichia coli, has two components, LivG and LivF, that are homologous to the cystic fibrosis (CF) transmembrane conductance regulator (CFTR). CF-associated mutations of human CFTR were introduced into corresponding regions of LivG, and their effects on leucine transport could be grouped into three classes. Mutations were found that (i) abolished LIV-I--directed transport, (ii) retained about a quarter of wild-type activity at the Michaelis-Menten constant (KM), and (iii) had minimal activity at the KM. A mutation equivalent to a benign polymorphism had no effect on transport. The correlation of these mutational phenotypes in LivG and CFTR suggests that the LIV-I prokaryotic transporter is functionally similar to the CF protein and that this similarity can be exploited to clarify the properties of the nucleotide-binding fold in this superfamily of proteins.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Gibson, A L -- Wagner, L M -- Collins, F S -- Oxender, D L -- New York, N.Y. -- Science. 1991 Oct 4;254(5028):109-11.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biological Chemistry, University of Michigan, Ann Arbor 48109.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/1718037" target="_blank"〉PubMed〈/a〉

    Structure and functional expression of a human interleukin-8 receptor (1991)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1991-09-13
    Description: Interleukin-8 (IL-8) is a member of a family of pro-inflammatory cytokines. Although the best characterized activities of IL-8 include the chemoattraction and activation of neutrophils, other members of this family have a wide range of specific actions including the chemotaxis and activation of monocytes, the selective chemotaxis of memory T cells, the inhibition of hematopoietic stem cell proliferation, and the induction of neutrophil infiltration in vivo. A complementary DNA encoding the IL-8 receptor from human neutrophils has now been isolated. The amino acid sequence shows that the receptor is a member of the superfamily of receptors that couple to guanine nucleotide binding proteins (G proteins). The sequence is 29% identical to that of receptors for the other neutrophil chemoattractants, fMet-Leu-Phe and C5a. Mammalian cells transfected with the IL-8 receptor cDNA clone bind IL-8 with high affinity and respond specifically to IL-8 by transiently mobilizing calcium. The IL-8 receptor may be part of a subfamily of related G protein-coupled receptors that transduce signals for the IL-8 family of pro-inflammatory cytokines.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Holmes, W E -- Lee, J -- Kuang, W J -- Rice, G C -- Wood, W I -- New York, N.Y. -- Science. 1991 Sep 13;253(5025):1278-80.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Molecular Biology, Genentech, Inc., South San Francisco, CA 94080.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/1840701" target="_blank"〉PubMed〈/a〉

    Description: Voltage-gated sodium channels, which are responsible for the generation of action potentials in the brain, are phosphorylated by protein kinase C (PKC) in purified form. Activation of PKC decreases peak sodium current up to 80 percent and slows its inactivation for sodium channels in rat brain neurons and for rat brain type IIA sodium channel alpha subunits heterologously expressed in Chinese hamster ovary cells. These effects are specific for PKC because they can be blocked by specific peptide inhibitors of PKC and can be reproduced by direct application of PKC to the cytoplasmic surface of sodium channels in excised inside-out membrane patches. Modulation of brain sodium channels by PKC is likely to have important effects on signal transduction and synaptic transmission in the central nervous system.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Numann, R -- Catterall, W A -- Scheuer, T -- NS15751/NS/NINDS NIH HHS/ -- NS25704/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 1991 Oct 4;254(5028):115-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Pharmacology, University of Washington, Seattle 98195.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/1656525" target="_blank"〉PubMed〈/a〉

    Rel-associated pp40: an inhibitor of the rel family of transcription factors (1991)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1991-09-23
    Description: The Rel-associated protein pp40 is functionally related to I kappa B, an inhibitor of the transcription factor NF-kappa B. Purified pp40 inhibits the DNA binding activity of the NF-kappa B protein complex (p50:p65 heterodimers), p50:c-Rel heteromers, and c-Rel homodimers. The sequence of the complementary DNA encoding pp40 revealed similarity to the gene encoding MAD-3, a protein with mammalian I kappa B-like activity. Protein sequencing of I kappa B purified from rabbit lung confirmed that MAD-3 encodes a protein similar to I kappa B. The sequence similarity between MAD-3 and pp40 includes a casein kinase II and consensus tyrosine phosphorylation site, as well as five repeats of a sequence found in the human erythrocyte protein ankyrin. These results suggest that rel-related transcription factors, which are capable of cytosolic to nuclear translocation, may be held in the cytosol by interaction with related cytoplasmic anchor molecules.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Davis, N -- Ghosh, S -- Simmons, D L -- Tempst, P -- Liou, H C -- Baltimore, D -- Bose, H R Jr -- CA09583/CA/NCI NIH HHS/ -- CA2616/CA/NCI NIH HHS/ -- CA33192/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 1991 Sep 13;253(5025):1268-71.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Microbiology, University of Texas, Austin 78712.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/1891714" target="_blank"〉PubMed〈/a〉

    Mitotic phosphorylation of the Oct-1 homeodomain and regulation of Oct-1 DNA binding activity (1991)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1991-12-20
    Description: Oct-1 is a transcription factor involved in the cell cycle regulation of histone H2B gene transcription and in the transcription of other cellular housekeeping genes. Oct-1 is hyperphosphorylated as cells enter mitosis, and mitosis-specific phosphorylation is reversed as cells exit mitosis. A mitosis-specific phosphorylation site in the homeodomain of Oct-1 was phosphorylated in vitro by protein kinase A. Phosphorylation of this site correlated with inhibition of Oct-1 DNA binding activity in vivo and in vitro. The inhibition of Oct-1 DNA binding during mitosis suggests a mechanism by which the general inhibition of transcription during mitosis might occur.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Segil, N -- Roberts, S B -- Heintz, N -- GM 13752/GM/NIGMS NIH HHS/ -- GM 32544/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1991 Dec 20;254(5039):1814-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Laboratory of Molecular Biology, Howard Hughes Medical Institute, Rockefeller University, New York, NY 10021.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/1684878" target="_blank"〉PubMed〈/a〉

    CREB: a Ca(2+)-regulated transcription factor phosphorylated by calmodulin-dependent kinases (1991)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1991-06-07
    Description: The mechanism by which Ca2+ mediates gene induction in response to membrane depolarization was investigated. The adenosine 3',5'-monophosphate (cAMP) response element-binding protein (CREB) was shown to function as a Ca(2+)-regulated transcription factor and as a substrate for depolarization-activated Ca(2+)-calmodulin-dependent protein kinases (CaM kinases) I and II. CREB residue Ser133 was the major site of phosphorylation by the CaM kinases in vitro and of phosphorylation after membrane depolarization in vivo. Mutation of Ser133 impaired the ability of CREB to respond to Ca2+. These results suggest that CaM kinases may transduce electrical signals to the nucleus and that CREB functions to integrate Ca2+ and cAMP signals.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Sheng, M -- Thompson, M A -- Greenberg, M E -- R01 CA 43855/CA/NCI NIH HHS/ -- R01 NS 28829/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 1991 Jun 7;252(5011):1427-30.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Microbiology and Molecular Genetics, Harvard Medical School, Boston, MA 02115.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/1646483" target="_blank"〉PubMed〈/a〉

    Novel enzymic hydrolytic dehalogenation of a chlorinated aromatic (1991)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1991-07-12
    Description: Microbial enzyme systems may be used in the biodegradation of persistent environmental pollutants. The three polypeptide components of one such system, the 4-chlorobenzoate dehalogenase system, have been isolated, and the chemical steps of the 4-hydroxybenzoate-forming reaction that they catalyze have been identified. The genes contained within a 4.5-kilobase Pseudomonas sp. strain CBS3 chromosomal DNA fragment that encode dehalogenase activity were selectively expressed in transformed Escherichia coli. Oligonucleotide sequencing revealed a stretch of homology between the 57-kilodalton (kD) polypeptide and several magnesium adenosine triphosphate (MgATP)-cleaving enzymes that allowed MgATP and coenzyme A (CoA) to be identified as the dehalogenase cosubstrate and cofactor, respectively. The dehalogenase activity arises from two components, a 4-chlorobenzoate:CoA ligase-dehalogenase (an alpha beta dimer of the 57- and 30-kD polypeptides) and a thioesterase (the 16-kD polypeptide).〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Scholten, J D -- Chang, K H -- Babbitt, P C -- Charest, H -- Sylvestre, M -- Dunaway-Mariano, D -- GM 28688/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1991 Jul 12;253(5016):182-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Chemistry and Biochemistry, University of Maryland, College Park 20742.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/1853203" target="_blank"〉PubMed〈/a〉

    Details
    Publication Date: 1991-12-30
    Description: L1 elements are highly repeated mammalian DNA sequences whose structure suggests dispersal by retrotransposition. A consensus L1 element encodes a protein with sequence similarity to known reverse transcriptases. The second open reading frame from the human L1 element L1.2A was expressed as a fusion protein targeted to Ty1 virus-like particles in Saccharomyces cerevisiae and shown to have reverse transcriptase activity. This activity was eliminated by a missense mutation in the highly conserved amino acid motif Y/F-X-D-D. Thus, L1 represents a potential source of the reverse transcriptase activity necessary for dispersion of the many classes of mammalian retroelements.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Mathias, S L -- Scott, A F -- Kazazian, H H Jr -- Boeke, J D -- Gabriel, A -- AI00803/AI/NIAID NIH HHS/ -- CA16519/CA/NCI NIH HHS/ -- GM28931/GM/NIGMS NIH HHS/ -- etc. -- New York, N.Y. -- Science. 1991 Dec 20;254(5039):1808-10.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Medicine, Johns Hopkins University School of Medicine, Baltimore, MD 21205.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/1722352" target="_blank"〉PubMed〈/a〉

    LAV revisited: origins of the early HIV-1 isolates from Institut Pasteur (1991)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1991-05-17
    Description: Two of the first human immunodeficiency virus type-1 (HIV-1) strains isolated were authenticated by reanalyzing original cultured samples stored at the Collection Nationale de Culture des Microorganismes as well as uncultured primary material. Cloned polymerase chain reaction products were used to analyze coding sequences of the V3 loop in the gp120 glycoprotein. The original isolate HIV-1 Bru, formerly called LAV, was derived from patient BRU. HIV-1 Lai was derived from patient LAI and contaminated a HIV-1 Bru culture between 20 July and 3 August 1983. The culture became, in effect, HIV-1 Lai, identifiable by a unique motif in the V3 loop. Because of this contamination two, rather than one, HIV-1 isolates were sent to the Laboratory of Tumor Cell Biology at the National Cancer Institute on 23 September 1983. Original HIV-1 Bru was indeed present in the sample marked JBB/LAV. However the M2T-/B sample harbored HIV-1 Lai, a strain capable of growing on established cell lines. The striking similarity between HIV-1 Lai (formerly LAV-Bru) and HTLV-3B sequences remains.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Wain-Hobson, S -- Vartanian, J P -- Henry, M -- Chenciner, N -- Cheynier, R -- Delassus, S -- Martins, L P -- Sala, M -- Nugeyre, M T -- Guetard, D -- New York, N.Y. -- Science. 1991 May 17;252(5008):961-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Laboratoire de Retrovirologie Moleculaire, Institut Pasteur, Paris.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2035026" target="_blank"〉PubMed〈/a〉

    Presence of an SH2 domain in the actin-binding protein tensin (1991)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1991-05-03
    Description: The molecular cloning of the complementary DNA coding for a 90-kilodalton fragment of tensin, an actin-binding component of focal contacts and other submembraneous cytoskeletal structures, is reported. The derived amino acid sequence revealed the presence of a Src homology 2 (SH2) domain. This domain is shared by a number of signal transduction proteins including nonreceptor tyrosine kinases such as Abl, Fps, Src, and Src family members, the transforming protein Crk, phospholipase C-gamma 1, PI-3 (phosphatidylinositol) kinase, and guanosine triphosphatase-activating protein (GAP). Like the SH2 domain found in Src, Crk, and Abl, the SH2 domain of tensin bound specifically to a number of phosphotyrosine-containing proteins from v-src-transformed cells. Tensin was also found to be phosphorylated on tyrosine residues. These findings suggest that by possessing both actin-binding and phosphotyrosine-binding activities and being itself a target for tyrosine kinases, tensin may link signal transduction pathways with the cytoskeleton.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Davis, S -- Lu, M L -- Lo, S H -- Lin, S -- Butler, J A -- Druker, B J -- Roberts, T M -- An, Q -- Chen, L B -- GM 22289/GM/NIGMS NIH HHS/ -- GM 38318/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1991 May 3;252(5006):712-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Division of Cellular and Molecular Biology, Dana-Farber Cancer Institute, Harvard Medical School, Boston, MA 02115.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/1708917" target="_blank"〉PubMed〈/a〉

    The receptor for ciliary neurotrophic factor (1991)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1991-07-05
    Description: Although neurotrophic factors were originally isolated on the basis of their ability to support the survival of neurons, these molecules are now thought to influence many aspects of the development and maintenance of the nervous system. Identifying the receptors for these neurotrophic factors should aid in identifying the cells on which these factors act and in understanding their precise mechanisms of action. A "tagged-ligand panning" procedure was used to clone a receptor for ciliary neurotrophic factor (CNTF). This receptor is expressed exclusively within the nervous system and skeletal muscle. The CNTF receptor has a structure unrelated to the receptors utilized by the nerve growth factor family of neurotrophic molecules, but instead is most homologous to the receptor for a cytokine, interleukin-6. This similarity suggestes that the CNTF receptor, like the interleukin-6 receptor, requires a second, signal-transducing component. In contrast to all known receptors, the CNTF receptor is anchored to cell membranes by a glycosyl-phosphatidylinositol linkage.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Davis, S -- Aldrich, T H -- Valenzuela, D M -- Wong, V V -- Furth, M E -- Squinto, S P -- Yancopoulos, G D -- New York, N.Y. -- Science. 1991 Jul 5;253(5015):59-63.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Regeneron Pharmaceuticals, Inc., Tarrytown, NY 10591.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/1648265" target="_blank"〉PubMed〈/a〉

    Identification of a site in glutamate receptor subunits that controls calcium permeability (1991)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1991-08-30
    Description: The neurotransmitter glutamate mediates excitatory synaptic transmission throughout the brain. A family of genes encoding subunits of the non-N-methyl-D-aspartate (non-NMDA) type of glutamate receptor has been cloned. Some combinations of these subunits assemble into receptors with a substantial permeability to calcium, whereas others do not. To investigate the structural features that control ion permeation through these ligand-gated channels, mutant receptor subunits with single-amino acid changes were constructed. Mutation of a certain amino acid that results in a net charge change (from glutamine to arginine or vice versa) alters both the current-voltage relation and the calcium permeability of non-NMDA receptors. A site has thus been identified that regulates the permeation properties of these glutamate receptors.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hume, R I -- Dingledine, R -- Heinemann, S F -- NS21043/NS/NINDS NIH HHS/ -- NS25782/NS/NINDS NIH HHS/ -- NS28709/NS/NINDS NIH HHS/ -- etc. -- New York, N.Y. -- Science. 1991 Aug 30;253(5023):1028-31.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Molecular Neurobiology Laboratory, Salk Institute, La Jolla, CA 92037.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/1653450" target="_blank"〉PubMed〈/a〉

A murine macrophage cell line, but not a fibroblast cell line, that was transfected with human Fc gamma RIIA mediated phagocytosis and an intracellular Ca2+ concentration ([Ca2+]i) flux upon cross-linking of human Fc gamma RIIA. Transfected macrophages that expressed a truncated receptor lacking 17 carboxy-terminal amino acids phagocytosed small antibody complexes. However, only wild-type transfectants phagocytosed labeled erythrocytes and fluxed [Ca2+]i.

    Description: Loss of sensitivity to growth inhibitory polypeptides is likely to be one of the events that participates in the formation of some tumors and might be caused by inactivation or loss of the genetic elements that transduce these extracellular signals. The isolation of such a gene was achieved by randomly inactivating genes by an anti-sense complementary DNA expression library followed by direct selection for growth in the presence of an inhibitory polypeptide.

    Primary structure and functional activity of a phosphatidylinositol-glycan-specific phospholipase D (1991)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1991-04-19
    Description: A phosphatidylinositol-glycan-specific phospholipase D (PI-G PLD) that specifically hydrolyzes the inositol phosphate linkage in proteins anchored by phosphatidylinositol-glycans (PI-Gs) has recently been purified from human and bovine sera. The primary structure of bovine PI-G PLD has now been determined and the functional activity of the enzyme has been studied. Expression of PI-G PLD complementary DNA in COS cells produced a protein that specifically hydrolyzed the inositol phosphate linkage of the PI-G anchor. Cotransfection of PI-G PLD with a PI-G-anchored protein resulted in the secretion of the PI-G-anchored protein. The results suggest that the expression of PI-G PLD may influence the expression and location of PI-G-anchored proteins.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Scallon, B J -- Fung, W J -- Tsang, T C -- Li, S -- Kado-Fong, H -- Huang, K S -- Kochan, J P -- New York, N.Y. -- Science. 1991 Apr 19;252(5004):446-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Molecular/Cellular Biology and Biochemistry, Hoffmann-La Roche, Inc., Nutley, NJ 07110.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2017684" target="_blank"〉PubMed〈/a〉

    Details
    Publication Date: 1991-10-25
    Description: Early in the process of spore formation in Bacillus subtilis a septum is formed that partitions the sporangium into daughter cells called the forespore and the mother cell. The daughter cells each have their own chromosome but follow dissimilar programs of gene expression. Differential gene expression in the forespore is now shown to be established by the compartmentalized activity of the transcription factor sigma F. The sigma F factor is produced prior to septation, but is active only in the forespore compartment of the post-septation sporangium. The sigma F factor is controlled by the products of sporulation operons spoIIA and spoIIE, which may be responsible for confining its activity to one of the daughter cells.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Margolis, P -- Driks, A -- Losick, R -- GM18568/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1991 Oct 25;254(5031):562-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Cellular and Developmental Biology, Harvard University, Cambridge, MA 02138.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/1948031" target="_blank"〉PubMed〈/a〉

The DA transporter is a 619-amino acid protein with 12 hydrophobic putative membrane-spanning domains and homology to the norepinephrine and gamma-aminobutyric acid transporters. The expressed complementary DNA confers transport of [3H]DA in Xenopus oocytes and in COS cells.

    Modular organization of genes required for complex polyketide biosynthesis (1991)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1991-05-03
    Description: In Saccharopolyspora erythraea, the genes that govern synthesis of the polyketide portion of the macrolide antibiotic erythromycin are organized in six repeated units that encode fatty acid synthase (FAS)-like activities. Each repeated unit is designated a module, and two modules are contained in a single open reading frame. A model for the synthesis of this complex polyketide is proposed, where each module encodes a functional synthase unit and each synthase unit participates specifically in one of the six FAS-like elongation steps required for formation of the polyketide. In addition, genetic organization and biochemical order of events appear to be colinear. Evidence for the model is provided by construction of a selected mutant and by isolation of a polyketide of predicted structure.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Donadio, S -- Staver, M J -- McAlpine, J B -- Swanson, S J -- Katz, L -- New York, N.Y. -- Science. 1991 May 3;252(5006):675-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Corporate Molecular Biology, Abbott Laboratories, Abbott Park, IL 60064.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2024119" target="_blank"〉PubMed〈/a〉

    Description: Insects and other invertebrates use glutamate as a neurotransmitter in the central nervous system and at the neuromuscular junction. A complementary DNA from Drosophila melanogaster, designated DGluR-II, has been isolated that encodes a distant homolog of the cloned mammalian ionotropic glutamate receptor family and is expressed in somatic muscle tissue of Drosophila embryos. Electrophysiological recordings made in Xenopus oocytes that express DGluR-II revealed depolarizing responses to L-glutamate and L-aspartate but low sensitivity to quisqualate, alpha-amino-3-hydroxy-5-methyl-4-isoxazolepropionate (AMPA), and kainate. The DGluR-II protein may represent a distinct glutamate receptor subtype, which shares its structural design with other members of the ionotropic glutamate receptor family.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Schuster, C M -- Ultsch, A -- Schloss, P -- Cox, J A -- Schmitt, B -- Betz, H -- New York, N.Y. -- Science. 1991 Oct 4;254(5028):112-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Zentrum fur Molekulare Biologie, Universitat Heidelberg, Federal Republic of Germany.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/1681587" target="_blank"〉PubMed〈/a〉

    Arginine-mediated RNA recognition: the arginine fork (1991)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1991-05-24
    Description: Short peptides that contain the basic region of the HIV-1 Tat protein bind specifically to a bulged region in TAR RNA. A peptide that contained nine arginines (R9) also bound specifically to TAR, and a mutant Tat protein that contained R9 was fully active for transactivation. In contrast, a peptide that contained nine lysines (K9) bound TAR poorly and the corresponding protein gave only marginal activity. By starting with the K9 mutant and replacing lysine residues with arginines, a single arginine was identified that is required for specific binding and transactivation. Ethylation interference experiments suggest that this arginine contacts two adjacent phosphates at the RNA bulge. Model building suggests that the arginine eta nitrogens and the epsilon nitrogen can form specific networks of hydrogen bonds with adjacent pairs of phosphates and that these arrangements are likely to occur near RNA loops and bulges and not within double-stranded A-form RNA. Thus, arginine side chains may be commonly used to recognize specific RNA structures.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Calnan, B J -- Tidor, B -- Biancalana, S -- Hudson, D -- Frankel, A D -- AI29135/AI/NIAID NIH HHS/ -- New York, N.Y. -- Science. 1991 May 24;252(5009):1167-71.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Whitehead Institute for Biomedical Research, Nine Cambridge Center, MA 02142.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/1709522" target="_blank"〉PubMed〈/a〉

    Methylation-sensitive sequence-specific DNA binding by the c-Myc basic region (1991)

    Details
    Publication Date: 1991-01-11
    Description: The function of the c-Myc oncoprotein and its role in cell growth control is unclear. A basic region of c-Myc is structurally related to the basic motifs of helix-loop-helix (HLH) and leucine zipper proteins, which provide sequence-specific DNA binding function. The c-Myc basic region was tested for its ability to bind DNA by attaching it to the HLH dimerization interface of the E12 enhancer binding factor. Dimers of the chimeric protein, termed E6, specifically bound an E box element (GGCCACGTGACC) recognized by other HLH proteins in a manner dependent on the integrity of the c-Myc basic motif. Methylation of the core CpG in the E box recognition site specifically inhibited binding by E6, but not by two other HLH proteins. Expression of E6 (but not an E6 DNA binding mutant) suppressed the ability of c-myc to cooperate with H-ras in a rat embryo fibroblast transformation assay, suggesting that the DNA recognition specificity of E6 is related to that of c-Myc in vivo.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Prendergast, G C -- Ziff, E B -- New York, N.Y. -- Science. 1991 Jan 11;251(4990):186-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Howard Hughes Medical Institute, Department of Biochemistry, New York, NY.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/1987636" target="_blank"〉PubMed〈/a〉

    Publication Date: 1991-12-13
    Description: Many human melanoma tumors express antigens that are recognized in vitro by cytolytic T lymphocytes (CTLs) derived from the tumor-bearing patient. A gene was identified that directed the expression of antigen MZ2-E on a human melanoma cell line. This gene shows no similarity to known sequences and belongs to a family of at least three genes. It is expressed by the original melanoma cells, other melanoma cell lines, and by some tumor cells of other histological types. No expression was observed in a panel of normal tissues. Antigen MZ2-E appears to be presented by HLA-A1; anti-MZ2-E CTLs of the original patient recognized two melanoma cell lines of other HLA-A1 patients that expressed the gene. Thus, precisely targeted immunotherapy directed against antigen MZ2-E could be provided to individuals identified by HLA typing and analysis of the RNA of a small tumor sample.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉van der Bruggen, P -- Traversari, C -- Chomez, P -- Lurquin, C -- De Plaen, E -- Van den Eynde, B -- Knuth, A -- Boon, T -- New York, N.Y. -- Science. 1991 Dec 13;254(5038):1643-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Ludwig Institute for Cancer Research, Brussels, Belgium.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/1840703" target="_blank"〉PubMed〈/a〉

    Publication Date: 1991-06-21
    Description: Functional glutamate receptor (GluRs) were transiently expressed in cultured mammalian cells from cloned complementary DNAs encoding GluR-A, -B, -C, or -D polypeptides. The steady-state current-voltage (I-V) relations of glutamate- and kainate-induced currents through homomeric channels fell into two classes: channels composed of either the GluR-A, -C, and -D subunits showed doubly rectifying I-V curves, and channels composed of the GluR-B subunits displayed simple outward rectification. The presence of GluR-B subunits in heteromeric GluRs determined the I-V behavior of the resulting channels. Site-directed mutagenesis identified a single amino acid difference (glutamine to arginine) in the putative transmembrane segment TM2 responsible for subunit-specific I-V relationships. The properties of heteromeric wild-type and mutant GluRs revealed that the dominance of GluR-B is due to the arginine residue in the TM2 region.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Verdoorn, T A -- Burnashev, N -- Monyer, H -- Seeburg, P H -- Sakmann, B -- New York, N.Y. -- Science. 1991 Jun 21;252(5013):1715-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Max-Planck-Institut fur medizinische Forschung, Abteilung Zellphysiologie, Heidelberg, Federal Republic of Germany.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/1710829" target="_blank"〉PubMed〈/a〉

    Description: The translocation t(15;17) associated with acute promyelocytic leukemia results in the fusion of the retinoic acid receptor alpha (RARA) gene to the PML gene. Characterization of PML revealed that it is a putative zinc finger protein and potential transcription factor that is commonly expressed, with at least three major transcription products. PML breakpoints cluster in two regions on either side of an alternatively spliced exon. Although leukemic cells with translocations characteristically express only one fusion product, both PML/RARA (on the 15q+ derivative chromosome) and RARA/PML (on the 17q- derivative) are transcribed.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Goddard, A D -- Borrow, J -- Freemont, P S -- Solomon, E -- New York, N.Y. -- Science. 1991 Nov 29;254(5036):1371-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Somatic Cell Genetics Laboratory, Imperial Cancer Research Fund, London, United Kingdom.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/1720570" target="_blank"〉PubMed〈/a〉

    Fibroblast growth factor receptors from liver vary in three structural domains (1991)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1991-02-08
    Description: Changes in heparin-binding fibroblast growth factor gene expression and receptor phenotype occur during liver regeneration and in hepatoma cells. The nucleotide sequence of complementary DNA predicts that three amino-terminal domain motifs, two juxtamembrane motifs, and two intracellular carboxyl-terminal domain motifs combine to form a minimum of 6 and potentially 12 homologous polypeptides that constitute the growth factor receptor family in a single human liver cell population. Amino-terminal variants consisted of two transmembrane molecules that contained three and two immunoglobulin-like disulfide loops, as well as a potential intracellular form of the receptor. The two intracellular juxtamembrane motifs differed in a potential serine-threonine kinase phosphorylation site. One carboxyl-terminal motif was a putative tyrosine kinase that contained potential tyrosine phosphorylation sites. The second carboxyl-terminal motif was probably not a tyrosine kinase and did not exhibit the same candidate carboxyl-terminal tyrosine phosphorylation sites.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hou, J Z -- Kan, M K -- McKeehan, K -- McBride, G -- Adams, P -- McKeehan, W L -- New York, N.Y. -- Science. 1991 Feb 8;251(4994):665-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉W.
