    Isolation of an active human transposable element (1991)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1991-12-30
    Description: Two de novo insertions of truncated L1 elements into the factor VIII gene on the X chromosome have been identified that produced hemophilia A. A full-length L1 element that is the likely progenitor of one of these insertions was isolated by its sequence identity to the factor VIII insertion. This L1 element contains two open-reading frames and is one of at least four alleles of a locus on chromosome 22 that has been occupied by an L1 element for at least 6 million years.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Dombroski, B A -- Mathias, S L -- Nanthakumar, E -- Scott, A F -- Kazazian, H H Jr -- New York, N.Y. -- Science. 1991 Dec 20;254(5039):1805-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Pediatrics, 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/1662412" 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〉

    A heparin-binding growth factor secreted by macrophage-like cells that is related to EGF (1991)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1991-02-22
    Description: Macrophage-like U-937 cells secrete a 22-kilodalton heparin-binding growth factor that is mitogenic for BALB-3T3 fibroblasts and smooth muscle cells, but not endothelial cells. The amino acid sequence predicted from complementary DNA clones indicates that the mitogen is a new member of the epidermal growth factor (EGF) family. This heparin-binding EGF-like growth factor (HB-EGF) binds to EGF receptors on A-431 epidermoid carcinoma cells and smooth muscle cells, but is a far more potent mitogen for smooth muscle cells than is EGF. HB-EGF is also expressed in cultured human macrophages and may be involved in macrophage-mediated cellular proliferation.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Higashiyama, S -- Abraham, J A -- Miller, J -- Fiddes, J C -- Klagsbrun, M -- CA37392/CA/NCI NIH HHS/ -- CA45548/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 1991 Feb 22;251(4996):936-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Surgical Research, Children's Hospital, Boston, MA 02115.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/1840698" target="_blank"〉PubMed〈/a〉

    Atomic structure of acetylcholinesterase from Torpedo californica: a prototypic acetylcholine-binding protein (1991)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1991-08-23
    Description: The three-dimensional structure of acetylcholinesterase from Torpedo californica electric organ has been determined by x-ray analysis to 2.8 angstrom resolution. The form crystallized is the glycolipid-anchored homodimer that was purified subsequent to solubilization with a bacterial phosphatidylinositol-specific phospholipase C. The enzyme monomer is an alpha/beta protein that contains 537 amino acids. It consists of a 12-stranded mixed beta sheet surrounded by 14 alpha helices and bears a striking resemblance to several hydrolase structures including dienelactone hydrolase, serine carboxypeptidase-II, three neutral lipases, and haloalkane dehalogenase. The active site is unusual because it contains Glu, not Asp, in the Ser-His-acid catalytic triad and because the relation of the triad to the rest of the protein approximates a mirror image of that seen in the serine proteases. Furthermore, the active site lies near the bottom of a deep and narrow gorge that reaches halfway into the protein. Modeling of acetylcholine binding to the enzyme suggests that the quaternary ammonium ion is bound not to a negatively charged "anionic" site, but rather to some of the 14 aromatic residues that line the gorge.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Sussman, J L -- Harel, M -- Frolow, F -- Oefner, C -- Goldman, A -- Toker, L -- Silman, I -- New York, N.Y. -- Science. 1991 Aug 23;253(5022):872-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Structural Chemistry, Weizmann Institute of Science, Rehovot, Israel.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/1678899" target="_blank"〉PubMed〈/a〉

    HRR25, a putative protein kinase from budding yeast: association with repair of damaged DNA (1991)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1991-08-30
    Description: In simple eukaryotes, protein kinases regulate mitotic and meiotic cell cycles, the response to polypeptide pheromones, and the initiation of nuclear DNA synthesis. The protein HRR25 from the budding yeast Saccharomyces cerevisiae was defined by the mutation hrr25-1. This mutation resulted in sensitivity to continuous expression of the HO double-strand endonuclease, to methyl methanesulfonate, and to x-irradiation. Homozygotes of hrr25-1 were unable to sporulate and disruption and deletion of HRR25 interfered with mitotic and meiotic cell division. Sequence analysis revealed two distinctive regions in the protein. The NH2-terminus of HRR25 contains the hallmark features of protein kinases, whereas the COOH-terminus is rich in proline and glutamine. Mutations in HRR25 at conserved residues found in all protein kinases inactivated the gene, and these mutants exhibited the hrr25 null phenotypes. Taken together, the hrr25 mutant phenotypes and the features of the gene product indicate that HRR25 is a distinctive member of the protein kinase superfamily.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hoekstra, M F -- Liskay, R M -- Ou, A C -- DeMaggio, A J -- Burbee, D G -- Heffron, F -- New York, N.Y. -- Science. 1991 Aug 30;253(5023):1031-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Molecular Biology and Virology Laboratory, Salk Institute for Biological Studies, La Jolla, CA 92186.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/1887218" 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〉

    Specific DNA binding by c-Myb: evidence for a double helix-turn-helix-related motif (1991)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1991-09-06
    Description: The c-Myb protein is a sequence-specific DNA binding protein that activates transcription in hematopoietic cells. Three imperfect repeats (R1, R2, and R3) that contain regularly spaced tryptophan residues form the DNA binding domain of c-Myb. A fragment of c-Myb that contained the R2 and R3 regions bound specifically to a DNA sequence recognized by c-Myb plus ten additional base pairs at the 3' end of the element. The R2R3 fragment was predicted to contain two consecutive helix-turn-helix (HTH) motifs with unconventional turns. Mutagenesis of amino acids in R2R3 at positions that correspond to DNA-contacting amino acids in other HTH-containing proteins abolished specific DNA binding without affecting nonspecific DNA interactions.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Gabrielsen, O S -- Sentenac, A -- Fromageot, P -- New York, N.Y. -- Science. 1991 Sep 6;253(5024):1140-3.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Laboratoire d'Ingenierie des Proteines, Centre d'Etudes de Saclay, Gif-sur-Yvette, France.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/1887237" target="_blank"〉PubMed〈/a〉

    Description: Human immunodeficiency virus type 1 (HIV-1) gene expression is activated by Tat, a virally encoded protein. Tat trans-activation requires viral (trans-activation--responsive; TAR) RNA sequences located in the R region of the long terminal repeat (LTR). Existing evidence suggests that Tat probably cooperates with cellular factors that bind to TAR RNA in the overall trans-activation process. A HeLa complementary DNA was isolated and characterized that encodes a TAR RNA-binding protein (TRBP). TRBP activated the HIV-1 LTR and was synergistic with Tat function.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Gatignol, A -- Buckler-White, A -- Berkhout, B -- Jeang, K T -- New York, N.Y. -- Science. 1991 Mar 29;251(5001):1597-600.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Laboratory of Molecular Microbiology, National Institute 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/2011739" target="_blank"〉PubMed〈/a〉

    A component of calcium-activated potassium channels encoded by the Drosophila slo locus (1991)
    American Association for the Advancement of Science (AAAS)
    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〉

    Cloning of complementary DNA encoding a functional 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 an inflammatory cytokine that activates neutrophil chemotaxis, degranulation, and the respiratory burst. Neutrophils express receptors for IL-8 that are coupled to guanine nucleotide-binding proteins (G proteins); binding of IL-8 to its receptor induces the mobilization of intracellular calcium stores. A cDNA clone from HL-60 neutrophils, designated p2, has now been isolated that encodes a human IL-8 receptor. When p2 is expressed in oocytes from Xenopus laevis, the oocytes bind 125I-labeled IL-8 specifically and respond to IL-8 by mobilizing calcium stores with an EC50 of 20 nM. This IL-8 receptor has 77% amino acid identity with a second human neutrophil receptor isotype that binds IL-8 with higher affinity. It also exhibits 69% amino acid identity with a protein reported to be an N-formyl peptide receptor from rabbit neutrophils, but less than 30% identity with all other known G protein-coupled receptors, including the human N-formyl peptide receptor.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Murphy, P M -- Tiffany, H L -- New York, N.Y. -- Science. 1991 Sep 13;253(5025):1280-3.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Laboratory of Host Defenses, National Institute 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/1891716" 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〉

    Deleted HTLV-I provirus in blood and cutaneous lesions of patients with mycosis fungoides (1991)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1991-07-19
    Description: Mycosis fungoides, a rare form of cutaneous T cell leukemia/lymphoma, is suspected of having a viral etiology on the basis of certain similarities to adult T cell leukemia, which is associated with human T cell leukemia/lymphoma virus type I (HTLV-I) infection. Cell lines were established from peripheral blood mononuclear cells (PBMC) of an HTLV-I-seronegative patient with mycosis fungoides. DNA hybridization analysis revealed the presence of HTLV-I-related sequences with unusual restriction endonuclease sites. Sequence analysis of subcloned fragments demonstrated the presence of a monoclonally integrated provirus with a 5.5-kilobase deletion involving large regions of gag and env and all of pol. Additional evidence for the presence of deleted proviruses was found by polymerase chain reaction (PCR) amplification of DNA from cutaneous lesions of five other HTLV-I-seronegative patients. The findings suggest that HTLV-I infection may be involved in the etiology of at least certain cases of mycosis fungoides.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hall, W W -- Liu, C R -- Schneewind, O -- Takahashi, H -- Kaplan, M H -- Roupe, G -- Vahlne, A -- CA51012-01A1/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 1991 Jul 19;253(5017):317-20.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Division of Infectious Disease, North Shore University Hospital-Cornell University Medical College, Manhasset, NY 11030.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/1857968" target="_blank"〉PubMed〈/a〉

    Identification of a gene located at chromosome 5q21 that is mutated in colorectal cancers (1991)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1991-03-15
    Description: Recent studies have suggested the existence of a tumor suppressor gene located at chromosome region 5q21. DNA probes from this region were used to study a panel of sporadic colorectal carcinomas. One of these probes, cosmid 5.71, detected a somatically rearranged restriction fragment in the DNA from a single tumor. Further analysis of the 5.71 cosmid revealed two regions that were highly conserved in rodent DNA. These sequences were used to identify a gene, MCC (mutated in colorectal cancer), which encodes an 829-amino acid protein with a short region of similarity to the G protein-coupled m3 muscarinic acetylcholine receptor. The rearrangement in the tumor disrupted the coding region of the MCC gene. Moreover, two colorectal tumors were found with somatically acquired point mutations in MCC that resulted in amino acid substitutions. MCC is thus a candidate for the putative colorectal tumor suppressor gene located at 5q21. Further studies will be required to determine whether the gene is mutated in other sporadic tumors or in the germ line of patients with an inherited predisposition to colonic tumorigenesis.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kinzler, K W -- Nilbert, M C -- Vogelstein, B -- Bryan, T M -- Levy, D B -- Smith, K J -- Preisinger, A C -- Hamilton, S R -- Hedge, P -- Markham, A -- 6M 07184/PHS HHS/ -- CA 06973/CA/NCI NIH HHS/ -- CA 09243/CA/NCI NIH HHS/ -- etc. -- New York, N.Y. -- Science. 1991 Mar 15;251(4999):1366-70.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Molecular Genetics Laboratory, Johns Hopkins Oncology Center, Baltimore, MD 21231.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/1848370" target="_blank"〉PubMed〈/a〉

    Targets for cell cycle arrest by the immunosuppressant rapamycin in yeast (1991)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1991-08-23
    Description: FK506 and rapamycin are related immunosuppressive compounds that block helper T cell activation by interfering with signal transduction. In vitro, both drugs bind and inhibit the FK506-binding protein (FKBP) proline rotamase. Saccharomyces cerevisiae cells treated with rapamycin irreversibly arrested in the G1 phase of the cell cycle. An FKBP-rapamycin complex is concluded to be the toxic agent because (i) strains that lack FKBP proline rotamase, encoded by FPR1, were viable and fully resistant to rapamycin and (ii) FK506 antagonized rapamycin toxicity in vivo. Mutations that conferred rapamycin resistance altered conserved residues in FKBP that are critical for drug binding. Two genes other than FPR1, named TOR1 and TOR2, that participate in rapamycin toxicity were identified. Nonallelic noncomplementation between FPR1, TOR1, and TOR2 alleles suggests that the products of these genes may interact as subunits of a protein complex. Such a complex may mediate nuclear entry of signals required for progression through the cell cycle.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Heitman, J -- Movva, N R -- Hall, M N -- New York, N.Y. -- Science. 1991 Aug 23;253(5022):905-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biochemistry, University of Basel, Switzerland.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/1715094" 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〉

    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〉

    Details
    Publication Date: 1991-05-03
    Description: The x-ray crystal structure of recombinant human interferon-gamma has been determined with the use of multiple-isomorphous-replacement techniques. Interferon-gamma, which is dimeric in solution, crystallizes with two dimers related by a noncrystallographic twofold axis in the asymmetric unit. The protein is primarily alpha helical, with six helices in each subunit that comprise approximately 62 percent of the structure; there is no beta sheet. The dimeric structure of human interferon-gamma is stabilized by the intertwining of helices across the subunit interface with multiple intersubunit interactions.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Ealick, S E -- Cook, W J -- Vijay-Kumar, S -- Carson, M -- Nagabhushan, T L -- Trotta, P P -- Bugg, C E -- CA-13148/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 1991 May 3;252(5006):698-702.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Pharmacology, University of Alabama, Birmingham 35294.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/1902591" target="_blank"〉PubMed〈/a〉

    Recoverin: a calcium sensitive activator of retinal rod guanylate cyclase (1991)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1991-02-22
    Description: Vertebrate retinal photoreceptors recover from photoexcitation-induced hydrolysis of guanosine 3', 5'-monophosphate (cyclic GMP) by resynthesizing cyclic GMP, which reopens cation channels that have been closed by light. Activation of guanylate cyclase by light-induced depletion of cytosolic calcium is a key event in this recovery process. This cyclase has now been shown to be regulated by a 23-kilodalton calcium binding protein. The protein is present in both rod and cone photoreceptors and was named recoverin because it promotes recovery of the dark state. The amino acid sequence of recoverin exhibits three potential calcium binding sites (EF hands). That recoverin binds calcium was confirmed with calcium-45 and by observing calcium-induced changes in its tryptophan fluorescence. Recoverin activated guanylate cyclase when free calcium was lowered from 450 to 40 nM, an effect that was blocked by an antibody to recoverin. Thus, guanylate cyclase in retinal rods is stimulated during recovery by the calcium-free form of recoverin. A comparison of recoverin with other calcium binding proteins reveals that it may represent, along with the protein visinin, a family of proteins that are regulated by submicromolar calcium concentrations.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Dizhoor, A M -- Ray, S -- Kumar, S -- Niemi, G -- Spencer, M -- Brolley, D -- Walsh, K A -- Philipov, P P -- Hurley, J B -- Stryer, L -- EY02005/EY/NEI NIH HHS/ -- EY06641/EY/NEI NIH HHS/ -- GM15731/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1991 Feb 22;251(4996):915-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Belozersky Laboratory of Molecular Biology and Bioorganic Chemistry, Moscow State University, USSR.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/1672047" target="_blank"〉PubMed〈/a〉

    Atomic structure of ferredoxin-NADP+ reductase: prototype for a structurally novel flavoenzyme family (1991)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1991-01-04
    Description: The three-dimensional structure of spinach ferredoxin-NADP+ reductase (NADP+, nicotinamide adenine dinucleotide phosphate) has been determined by x-ray diffraction at 2.6 angstroms (A) resolution and initially refined to an R factor of 0.226 at 2.2 A resolution. The model includes the flavin-adenine dinucleotide (FAD) prosthetic group and the protein chain from residue 19 through the carboxyl terminus at residue 314 and is composed of two domains. The FAD binding domain (residues 19 to 161) has an antiparallel beta barrel core and a single alpha helix for binding the pyrophosphate of FAD. The NADP binding domain (residues 162 to 314) has a central five-strand parallel beta sheet and six surrounding helices. Binding of the competitive inhibitor 2'-phospho-AMP (AMP, adenosine monophosphate) places the NADP binding site at the carboxyl-terminal edge of the sheet in a manner similar to the nucleotide binding of the dehydrogenase family. The structures reveal the key residues that function in cofactor binding and the catalytic center. With these key residues as a guide, conclusive evidence is presented that the ferredoxin reductase structure is a prototype for the nicotinamide dinucleotide and FAD binding domains of the enzymes NADPH-cytochrome P450 reductase, NADPH-sulfite reductase, NADH-cytochrome b5 reductase, and NADH-nitrate reductase. Thus this structure provides a structural framework for the NADH- or NADPH-dependent flavoenzyme parts of five distinct enzymes involved in photosynthesis, in the assimilation of inorganic nitrogen and sulfur, in fatty-acid oxidation, in the reduction of methemoglobin, and in the metabolism of many pesticides, drugs, and carcinogens.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Karplus, P A -- Daniels, M J -- Herriott, J R -- New York, N.Y. -- Science. 1991 Jan 4;251(4989):60-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biochemistry, Molecular and Cell Biology, Cornell University, Ithaca, NY 14853.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/1986412" target="_blank"〉PubMed〈/a〉

    Publication Date: 1991-01-04
    Description: Members of the fibroblast growth factor (FGF) family of proteins stimulate the proliferation and differentiation of a variety of cell types through receptor-mediated pathways. The three-dimensional structures of two members of this family, bovine acidic FGF and human basic FGF, have been crystallographically determined. These structures contain 12 antiparallel beta strands organized into a folding pattern with approximate threefold internal symmetry. Topologically equivalent folds have been previously observed for soybean trypsin inhibitor and interleukins-1 beta and -1 alpha. The locations of sequences implicated in receptor and heparin binding by FGF are presented. These sites include beta-sheet strand 10, which is adjacent to the site of an extended sequence insertion in several oncogene proteins of the FGF family, and which shows sequence conservation among the FGF family and interleukin-1 beta.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Zhu, X -- Komiya, H -- Chirino, A -- Faham, S -- Fox, G M -- Arakawa, T -- Hsu, B T -- Rees, D C -- New York, N.Y. -- Science. 1991 Jan 4;251(4989):90-3.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Division of Chemistry and Chemical Engineering, California Institute of Technology, Pasadena 91125.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/1702556" target="_blank"〉PubMed〈/a〉

    Details
    Publication Date: 1991-06-21
    Description: Automated partial DNA sequencing was conducted on more than 600 randomly selected human brain complementary DNA (cDNA) clones to generate expressed sequence tags (ESTs). ESTs have applications in the discovery of new human genes, mapping of the human genome, and identification of coding regions in genomic sequences. Of the sequences generated, 337 represent new genes, including 48 with significant similarity to genes from other organisms, such as a yeast RNA polymerase II subunit; Drosophila kinesin, Notch, and Enhancer of split; and a murine tyrosine kinase receptor. Forty-six ESTs were mapped to chromosomes after amplification by the polymerase chain reaction. This fast approach to cDNA characterization will facilitate the tagging of most human genes in a few years at a fraction of the cost of complete genomic sequencing, provide new genetic markers, and serve as a resource in diverse biological research fields.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Adams, M D -- Kelley, J M -- Gocayne, J D -- Dubnick, M -- Polymeropoulos, M H -- Xiao, H -- Merril, C R -- Wu, A -- Olde, B -- Moreno, R F -- New York, N.Y. -- Science. 1991 Jun 21;252(5013):1651-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Section of Receptor Biochemistry and Molecular Biology, National Institute of Neurological Disorders and Stroke, National Institutes of Health, Bethesda, MD.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2047873" target="_blank"〉PubMed〈/a〉

    SH2 and SH3 domains: elements that control interactions of cytoplasmic signaling proteins (1991)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1991-05-03
    Description: Src homology (SH) regions 2 and 3 are noncatalytic domains that are conserved among a series of cytoplasmic signaling proteins regulated by receptor protein-tyrosine kinases, including phospholipase C-gamma, Ras GTPase (guanosine triphosphatase)-activating protein, and Src-like tyrosine kinases. The SH2 domains of these signaling proteins bind tyrosine phosphorylated polypeptides, implicated in normal signaling and cellular transformation. Tyrosine phosphorylation acts as a switch to induce the binding of SH2 domains, thereby mediating the formation of heteromeric protein complexes at or near the plasma membrane. The formation of these complexes is likely to control the activation of signal transduction pathways by tyrosine kinases. The SH3 domain is a distinct motif that, together with SH2, may modulate interactions with the cytoskeleton and membrane. Some signaling and transforming proteins contain SH2 and SH3 domains unattached to any known catalytic element. These noncatalytic proteins may serve as adaptors to link tyrosine kinases to specific target proteins. These observations suggest that SH2 and SH3 domains participate in the control of intracellular responses to growth factor stimulation.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Koch, C A -- Anderson, D -- Moran, M F -- Ellis, C -- Pawson, T -- New York, N.Y. -- Science. 1991 May 3;252(5006):668-74.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Division of Molecular and Developmental Biology, Samuel Lunenfeld Research Institute, Mount Sinai Hospital, Toronto, Ontario, Canada.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/1708916" target="_blank"〉PubMed〈/a〉

    Spectral tuning of pigments underlying red-green color vision (1991)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1991-05-17
    Description: Variations in the absorption spectra of cone photopigments over the spectral range of about 530 to 562 nanometers are a principal cause of individual differences in human color vision and of differences in color vision within and across other primates. To study the molecular basis of these variations, nucleotide sequences were determined for eight primate photopigment genes. The spectral peaks of the pigments specified by these genes spanned the range from 530 to 562 nanometers. Comparisons of the deduced amino acid sequences of these eight pigments suggest that three amino acid substitutions produce the approximately 30-nanometer difference in spectral peaks of the pigments underlying human red-green color vision, and red shifts of specific magnitudes are produced by replacement of nonpolar with hydroxyl-bearing amino acids at each of the three critical positions.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Neitz, M -- Neitz, J -- Jacobs, G H -- EY-02052/EY/NEI NIH HHS/ -- EY-07200/EY/NEI NIH HHS/ -- New York, N.Y. -- Science. 1991 May 17;252(5008):971-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Psychology, University of California, Santa Barbara 93106.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/1903559" target="_blank"〉PubMed〈/a〉

    p53 mutations in human cancers (1991)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1991-07-05
    Description: Mutations in the evolutionarily conserved codons of the p53 tumor suppressor gene are common in diverse types of human cancer. The p53 mutational spectrum differs among cancers of the colon, lung, esophagus, breast, liver, brain, reticuloendothelial tissues, and hemopoietic tissues. Analysis of these mutations can provide clues to the etiology of these diverse tumors and to the function of specific regions of p53. Transitions predominate in colon, brain, and lymphoid malignancies, whereas G:C to T:A transversions are the most frequent substitutions observed in cancers of the lung and liver. Mutations at A:T base pairs are seen more frequently in esophageal carcinomas than in other solid tumors. Most transitions in colorectal carcinomas, brain tumors, leukemias, and lymphomas are at CpG dinucleotide mutational hot spots. G to T transversions in lung, breast, and esophageal carcinomas are dispersed among numerous codons. In liver tumors in persons from geographic areas in which both aflatoxin B1 and hepatitis B virus are cancer risk factors, most mutations are at one nucleotide pair of codon 249. These differences may reflect the etiological contributions of both exogenous and endogenous factors to human carcinogenesis.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hollstein, M -- Sidransky, D -- Vogelstein, B -- Harris, C C -- CA 09071/CA/NCI NIH HHS/ -- CA 43460/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 1991 Jul 5;253(5015):49-53.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Laboratory of Human Carcinogenesis, 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/1905840" target="_blank"〉PubMed〈/a〉

    LAV revisited: origins of the early HIV-1 isolates from Institut Pasteur (1991)

    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〉

    Description: Metal ion coordination in the regulatory domain of protein kinase C (PKC) is suggested by the conservation of six cysteines and two histidines in two homologous regions found therein. By monitoring x-ray fluorescence from a purified sample of rat PKC beta I overexpressed in insect cells, direct evidence has been obtained that PKC beta I tightly binds four zinc ions (Zn2+) per molecule. Extended x-ray absorption fine structure (EXAFS) data are best fit by an average Zn2+ coordination of one nitrogen and three sulfur atoms. Of the plausible Zn2+ coordination models, only those featuring nonbridged Zn2+ sites accommodate the EXAFS data and all of the conserved potential ligands.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hubbard, S R -- Bishop, W R -- Kirschmeier, P -- George, S J -- Cramer, S P -- Hendrickson, W A -- New York, N.Y. -- Science. 1991 Dec 20;254(5039):1776-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Howard Hughes Medical Institute, New York, NY.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/1763327" 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〉

    A distinct potassium channel polypeptide encoded by the Drosophila eag locus (1991)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1991-06-14
    Description: Many of the signaling properties of neurons and other electrically excitable cells are determined by a diverse family of potassium channels. A number of genes that encode potassium channel polypeptides have been cloned from various organisms on the basis of their sequence similarity to the Drosophila Shaker (Sh) locus. As an alternative strategy, a molecular analysis of other Drosophila genes that were defined by mutations that perturb potassium channel function was undertaken. Sequence analysis of complementary DNA from the ether a go-go (eag) locus revealed that it encodes a structural component of potassium channels that is related to but is distinct from all identified potassium channel polypeptides.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Warmke, J -- Drysdale, R -- Ganetzky, B -- NS15390/NS/NINDS NIH HHS/ -- T32GM07131/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1991 Jun 14;252(5012):1560-2.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Zoology, University of Cambridge, United Kingdom.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/1840699" target="_blank"〉PubMed〈/a〉

    Identification of the envelope V3 loop as the primary determinant of cell tropism in HIV-1 (1991)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1991-07-05
    Description: Cells of the monocyte-macrophage lineage are targets for human immunodeficiency virus-1 (HIV-1) infection in vivo. However, many laboratory strains of HIV-1 that efficiently infect transformed T cell lines replicate poorly in macrophages. A 20-amino acid sequence from the macrophage-tropic BaL isolate of HIV-1 was sufficient to confer macrophage tropism on HTLV-IIIB, a T cell line--tropic isolate. This small sequence element is in the V3 loop, the envelope domain that is the principal neutralizing determinant of HIV-1. Thus, the V3 loop not only serves as a target of the host immune response but is also pivotal in determining HIV-1 tissue tropism.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hwang, S S -- Boyle, T J -- Lyerly, H K -- Cullen, B R -- New York, N.Y. -- Science. 1991 Jul 5;253(5015):71-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Microbiology and Immunology, Duke University Medical Center, Durham, NC 27710.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/1905842" target="_blank"〉PubMed〈/a〉

    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〉

    A retroviral oncogene, akt, encoding a serine-threonine kinase containing an SH2-like region (1991)

    Publication Date: 1991-10-11
    Description: The v-akt oncogene codes for a 105-kilodalton fusion phosphoprotein containing Gag sequences at its amino terminus. Sequence analysis of v-akt and biochemical characterization of its product revealed that it codes for a protein kinase C-related serine-threonine kinase whose cellular homolog is expressed in most tissues, with the highest amount found in thymus. Although Akt is a serine-threonine kinase, part of its regulatory region is similar to the Src homology-2 domain, a structural motif characteristic of cytoplasmic tyrosine kinases that functions in protein-protein interactions. This suggests that Akt may form a functional link between tyrosine and serine-threonine phosphorylation pathways.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Bellacosa, A -- Testa, J R -- Staal, S P -- Tsichlis, P N -- CA-06927/CA/NCI NIH HHS/ -- CA-38047/CA/NCI NIH HHS/ -- RR-05539/RR/NCRR NIH HHS/ -- New York, N.Y. -- Science. 1991 Oct 11;254(5029):274-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Medical Oncology, Fox Chase Cancer Center, Philadelphia, PA 19111.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/1833819" target="_blank"〉PubMed〈/a〉

    Description: Human mitochondrial transcription factor 1 (mtTF1) has been sequenced and is a nucleus-encoded DNA binding protein of 204 amino acids (24,400 daltons). Expression of human mtTF1 in bacteria yields a protein with correct physical properties and the ability to activate mitochondrial DNA promoters. Analysis of the protein's sequence reveals no similarities to any other DNA binding proteins except for the existence of two domains that are characteristic of high mobility group (HMG) proteins. Human mtTF1 is most closely related to a DNA binding HMG-box region in hUBF, a human protein known to be important for transcription by RNA polymerase I.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Parisi, M A -- Clayton, D A -- GM07365-15/GM/NIGMS NIH HHS/ -- GM33088-20/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1991 May 17;252(5008):965-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Developmental Biology, Stanford University School of Medicine, CA 94305.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2035027" target="_blank"〉PubMed〈/a〉

    Identification of FAP locus genes from chromosome 5q21 (1991)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1991-08-09
    Description: Recent studies suggest that one or more genes on chromosome 5q21 are important for the development of colorectal cancers, particularly those associated with familial adenomatous polyposis (FAP). To facilitate the identification of genes from this locus, a portion of the region that is tightly linked to FAP was cloned. Six contiguous stretches of sequence (contigs) containing approximately 5.5 Mb of DNA were isolated. Subclones from these contigs were used to identify and position six genes, all of which were expressed in normal colonic mucosa. Two of these genes (APC and MCC) are likely to contribute to colorectal tumorigenesis. The MCC gene had previously been identified by virtue of its mutation in human colorectal tumors. The APC gene was identified in a contig initiated from the MCC gene and was found to encode an unusually large protein. These two closely spaced genes encode proteins predicted to contain coiled-coil regions. Both genes were also expressed in a wide variety of tissues. Further studies of MCC and APC and their potential interaction should prove useful for understanding colorectal neoplasia.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kinzler, K W -- Nilbert, M C -- Su, L K -- Vogelstein, B -- Bryan, T M -- Levy, D B -- Smith, K J -- Preisinger, A C -- Hedge, P -- McKechnie, D -- CA06973/CA/NCI NIH HHS/ -- CA35494/CA/NCI NIH HHS/ -- CA44688/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 1991 Aug 9;253(5020):661-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Molecular Genetics Laboratory, Johns Hopkins University School of Medicine, Baltimore, MD 21231.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/1651562" target="_blank"〉PubMed〈/a〉

    Publication Date: 1991-05-17
    Description: Calcium can function as a second messenger through stimulation of calcium-dependent protein kinases. A protein kinase that requires calcium but not calmodulin or phospholipids for activity has been purified from soybean. The kinase itself binds calcium with high affinity. A complementary DNA clone for this kinase has been identified; it encodes a protein with a predicted molecular mass of 57,175 daltons. This protein contains a catalytic domain similar to that of calmodulin-dependent kinases and a calmodulin-like region with four calcium binding domains (EF hands). The predicted structure of this kinase explains its direct regulation via calcium binding and establishes it as a prototype for a new family of calcium-regulated protein kinases.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Harper, J F -- Sussman, M R -- Schaller, G E -- Putnam-Evans, C -- Charbonneau, H -- Harmon, A C -- GM15731/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1991 May 17;252(5008):951-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Botany, Louisiana State University, Baton Rouge 70803.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/1852075" target="_blank"〉PubMed〈/a〉

    Publication Date: 1991-11-29
    Description: Three cytoplasmic proteins, called catenins, bind to the cytoplasmic tail of the epithelial cell-cell adhesion molecule E-cadherin. The complementary DNA sequence was determined for the 92-kilodalton beta catenin of Xenopus laevis. The sequence is homologous to mammalian plakoglobin, a protein of desmosomal and zonula adherens cell junctions, and to the plakoglobin homolog in Drosophila melanogaster, the product of the segment polarity gene armadillo. A monoclonal antibody to bovine plakoglobin recognizes the analogous beta catenin in the Madin-Darby canine kidney (MDCK) cell line. Armadillo plakoglobin may link E-cadherin to the underlying actin cytoskeleton at cell-cell junctions; the E-cadherin-catenin protein complex may also participate in the transmission of developmental information.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉McCrea, P D -- Turck, C W -- Gumbiner, B -- 5-F32-GM-13060/GM/NIGMS NIH HHS/ -- GM37432/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1991 Nov 29;254(5036):1359-61.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Pharmacology, University of California, San Francisco 94143.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/1962194" target="_blank"〉PubMed〈/a〉

The recombinant protein showed high affinity to poly-L-proline. Immunoglobulin E antibodies from allergic individuals bound to natural and recombinant birch profilin and also to human profilin. In addition, birch and human profilin induced histamine release from blood basophils of profilin-allergic individuals, but not of individuals sensitized to other plant allergens. The structural similarity of conserved proteins might therefore be responsible for maintaining immunoglobulin E antibody titers in type I allergy.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Valenta, R -- Duchene, M -- Pettenburger, K -- Sillaber, C -- Valent, P -- Bettelheim, P -- Breitenbach, M -- Rumpold, H -- Kraft, D -- Scheiner, O -- New York, N.Y. -- Science. 1991 Aug 2;253(5019):557-60.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Institute of General and Experimental Pathology, University of Vienna, Austria.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/1857985" target="_blank"〉PubMed〈/a〉

    Publication Date: 1991-11-01
    Description: Enteropathogenic Escherichia coli (EPEC), a cause of childhood diarrhea, grow on the surface of the small intestine and on cultured epithelial cells as colonies of adherent bacteria. When propagated on solid medium containing blood or attached to HEp-2 cells, EPEC express ropelike bundles of filaments, termed bundle-forming pili (BFP), that create a network of fibers that bind together the individual organisms. BFP were found to be expressed by five EPEC serogroups, each harboring a approximately 92-kilobase plasmid previously known to be important for virulence in humans. When two of these strains were cured of this plasmid, they neither expressed BFP nor grew as adherent colonies. An antiserum to BFP reduced the capacity of EPEC to infect cultured epithelial cells. BFP are composed of a repeating subunit of 19,500 daltons, the amino-terminal amino acid sequence of this subunit is homologous to that of the toxin-coregulated pilin of Vibrio cholerae.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Giron, J A -- Ho, A S -- Schoolnik, G K -- DK 38707/DK/NIDDK NIH HHS/ -- New York, N.Y. -- Science. 1991 Nov 1;254(5032):710-3.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Microbiology and Immunology, Beckman Center, Howard Hughes Medical Institute, Stanford University, CA 94305.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/1683004" target="_blank"〉PubMed〈/a〉

    Details
    Publication Date: 1991-11-29
    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〉

    Description: A complementary DNA encoding a G protein-coupled glutamate receptor from rat brain, GluGR, was cloned by functional expression in Xenopus oocytes. The complementary DNA encodes a protein of 1199 amino acids containing a seven-transmembrane motif, flanked by large amino- and carboxyl-terminal domains. This receptor lacks any amino acid sequence similarity with other G protein-coupled receptors, suggesting that it may be a member of a new subfamily. The presence of two introns flanking the central core suggests that GluGR may have evolved by exon shuffling. Expressed in oocytes, GluGR is activated by quisqualate greater than glutamate greater than ibotenate greater than trans-1-aminocyclopentyl-1,3-dicarboxylate, and it is inhibited by 2-amino-3-phosphonopropionate. Activation is blocked by Bordella pertussis toxin. These properties are typical of some metabotropic glutamate receptors.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Houamed, K M -- Kuijper, J L -- Gilbert, T L -- Haldeman, B A -- O'Hara, P J -- Mulvihill, E R -- Almers, W -- Hagen, F S -- AR 17803/AR/NIAMS NIH HHS/ -- New York, N.Y. -- Science. 1991 May 31;252(5010):1318-21.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Physiology and Biophysics, University of Washington School of Medicine, Seattle 98195.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/1656524" target="_blank"〉PubMed〈/a〉
