    Description: The T-cell antigen receptor is a cell surface molecule vital in mediating the cellular immune response. The arrangement and rearrangement of the gene segments encoding the beta-chain polypeptide of the receptor are similar to those of immunoglobulin gene segments. The two constant region genes of the human T-cell antigen receptor are 8 kilobases apart with a cluster of joining segments located 5' of each constant region gene. Although most beta-chain gene rearrangements involve the variable, diversity, and joining segments, analysis of a beta-chain complementary DNA clone suggests the occasional occurrence of another type of rearrangement.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Duby, A D -- Klein, K A -- Murre, C -- Seidman, J G -- AI-19438/AI/NIAID NIH HHS/ -- New York, N.Y. -- Science. 1985 Jun 7;228(4704):1204-6.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3839095" target="_blank"〉PubMed〈/a〉

    Description: A human complementary DNA clone specific for the alpha-chain of the T-cell receptor and a panel of rodent X human somatic cell hybrids were used to map the alpha-chain gene to human chromosome 14 in a region proximal to the immunoglobulin heavy chain locus. Analysis by means of in situ hybridization of human metaphase chromosomes served to further localize the alpha-chain gene to region 14q11q12, which is consistently involved in translocations and inversions detectable in human T-cell leukemias and lymphomas. Thus, the locus for the alpha-chain T-cell receptor may participate in oncogene activation in T-cell tumors.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Croce, C M -- Isobe, M -- Palumbo, A -- Puck, J -- Ming, J -- Tweardy, D -- Erikson, J -- Davis, M -- Rovera, G -- CA 10 815/CA/NCI NIH HHS/ -- CA16685/CA/NCI NIH HHS/ -- CA215875/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 1985 Mar 1;227(4690):1044-7.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3919442" target="_blank"〉PubMed〈/a〉

    Description: Phototransduction is the process by which light-stimulated photoreceptor cells of the visual system send electrical signals to the nervous system. Many of the steps that follow the initial event in phototransduction, absorption of light by rhodopsin, are ill-defined. The fruitfly, Drosophila melanogaster, provides a means to dissect phototransduction genetically. Mutations such as transient receptor potential (trp) affect intermediate steps in phototransduction. In order to facilitate molecular studies of phototransduction, the trp gene was isolated and its identity was confirmed by complementing the mutant trpCM allele of the trp gene by P-element mediated germline transformation of a 7.1-kilobase DNA fragment. Expression of the trp gene begins late in pupal development and appears to be limited to the eyes and ocelli.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Montell, C -- Jones, K -- Hafen, E -- Rubin, G -- New York, N.Y. -- Science. 1985 Nov 29;230(4729):1040-3.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3933112" target="_blank"〉PubMed〈/a〉

    Description: A complementary DNA library was constructed from messenger RNA's extracted from the brains of mice infected with the scrapie agent. The library was differentially screened with the objectives of finding clones that might be used as markers of infection and finding clones of genes whose increased expression might be correlated with the pathological changes common to scrapie and Alzheimer's disease. A gene was identified whose expression is increased in scrapie. The complementary DNA corresponding to this gene hybridized preferentially and focally to cells in the brains of scrapie-infected animals. The cloned DNA also hybridized to the neuritic plaques found with increased frequency in brains of patients with Alzheimer's disease.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Wietgrefe, S -- Zupancic, M -- Haase, A -- Chesebro, B -- Race, R -- Frey, W 2nd -- Rustan, T -- Friedman, R L -- New York, N.Y. -- Science. 1985 Dec 6;230(4730):1177-9.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3840915" target="_blank"〉PubMed〈/a〉

    Description: Several inherited disorders in humans and in rodents result in myelin dysgenesis and a deficiency of the molecular constituents of myelin. A complementary DNA to one of the two major myelin proteins, myelin proteolipid protein (also known as lipophilin), has been used with Southern blot analysis of somatic cell hybrid DNA to map the human proteolipid protein gene to the middle of the long arm of the human X chromosome (bands Xq13-Xq22) and to assign the murine proteolipid protein gene to the mouse X chromosome. Comparison of the gene maps of the human and mouse X chromosomes suggests that myelin proteolipid protein may be involved in X-linked mutations at the mouse jimpy locus and has implications for Pelizaeus-Merzbacher disease, a human inherited X-linked myelin disorder.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Willard, H F -- Riordan, J R -- New York, N.Y. -- Science. 1985 Nov 22;230(4728):940-2.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3840606" target="_blank"〉PubMed〈/a〉

    Description: The genes encoding the alpha chain of the human T-cell receptor have been mapped to chromosome 14, the chromosome on which the human immunoglobulin heavy chain locus resides. Thus, genes encoding two different classes of antigen receptor are present on the same chromosome. Furthermore, breaks involving chromosome 14 are frequently seen in tumors of T-cell origin. The potential relation of these chromosome abnormalities to alpha-chain genes is discussed.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Jones, C -- Morse, H G -- Kao, F T -- Carbone, A -- Palmer, E -- CA-18734/CA/NCI NIH HHS/ -- HD-02080/HD/NICHD NIH HHS/ -- HD-17717/HD/NICHD NIH HHS/ -- etc. -- New York, N.Y. -- Science. 1985 Apr 5;228(4695):83-5.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3919444" target="_blank"〉PubMed〈/a〉

    Description: Mutagenesis was studied in cultured F9 embryonal carcinoma cells infected with a variant of Moloney murine leukemia virus. Proviral insertion induced the inactivation of the hypoxanthine phosphoribosyltransferase locus, and the virus was used to isolate the mutated genes rapidly. Mutagenesis by these methods may be useful for the genetic dissection of the various mammalian cell phenotypes.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉King, W -- Patel, M D -- Lobel, L I -- Goff, S P -- Nguyen-Huu, M C -- New York, N.Y. -- Science. 1985 May 3;228(4699):554-8.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3838595" target="_blank"〉PubMed〈/a〉

    Description: Infection of human T cells by human T-lymphotropic virus, type I (HTLV-I), a retrovirus, is uniformly associated with the constitutive expression of large numbers of cellular receptors for interleukin-2 (IL-2). Comparison with normal T cells shows that neither IL-2 receptor gene organization nor IL-2 receptor messenger RNA processing are altered in the leukemic cells. However, mitogenic stimuli activate IL-2 receptor gene expression in normal T cells, whereas these stimuli paradoxically inhibit IL-2 receptor gene transcription in HTLV-I-infected leukemic T cells.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kronke, M -- Leonard, W J -- Depper, J M -- Greene, W C -- New York, N.Y. -- Science. 1985 Jun 7;228(4704):1215-7.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2988127" target="_blank"〉PubMed〈/a〉

    Description: The T-cell antigen receptor is a cell-surface molecule that participates in the immune response. In the present experiments the genes encoding the beta chain of the T-cell receptor were found to reside on the long arm of human chromosome 7 at or near band q32. Related sequences were found on the short arm of chromosome 7 in bands p15-21 in some experiments. Chromosomal rearrangements in T-cells from normal individuals and patients with ataxia telangiectasia have previously been observed at and near these map assignments for the beta-chain genes.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Morton, C C -- Duby, A D -- Eddy, R L -- Shows, T B -- Seidman, J G -- CA-07511/CA/NCI NIH HHS/ -- GM-20454/GM/NIGMS NIH HHS/ -- HD-05196/HD/NICHD NIH HHS/ -- etc. -- New York, N.Y. -- Science. 1985 May 3;228(4699):582-5.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3983642" target="_blank"〉PubMed〈/a〉

    Description: A bovine retinal complementary DNA clone encoding the alpha subunit of transducin (T alpha) was isolated with the use of synthetic oligodeoxynucleotides as probes, and the complete nucleotide sequence of the insert was determined. THe predicted protein sequence of 354 amino acids includes the known sequences of four tryptic peptides and sequences adjacent to the residues that undergo adenosine diphosphate ribosylation by cholera toxin and pertussis toxin. On the basis of homologies to other proteins, such as the elongation factors of protein synthesis and the ras oncogene proteins, regions are identified that are predicted to be acylated and involved in guanine nucleotide binding and hydrolysis. Amino acid sequence similarity between T alpha and ras is confined to these regions of the molecules.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lochrie, M A -- Hurley, J B -- Simon, M I -- New York, N.Y. -- Science. 1985 Apr 5;228(4695):96-9.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3856323" target="_blank"〉PubMed〈/a〉

    Description: Human recombinant granulocyte-macrophage colony-stimulating factor (GM-CSF) was tested for its ability to induce colony formation in human bone marrow that had been enriched for progenitor cells. In addition to its expected granulocyte-monocyte colony-stimulating activity, the recombinant GM-CSF had burst-promoting activity for erythroid burst-forming units and also stimulated colonies derived from multipotent (mixed) progenitors. In contrast, recombinant erythroid-potentiating activity did not stimulate erythroid progenitors. The experiments prove that human GM-CSF has multilineage colony-stimulating activity.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Sieff, C A -- Emerson, S G -- Donahue, R E -- Nathan, D G -- Wang, E A -- Wong, G G -- Clark, S C -- New York, N.Y. -- Science. 1985 Dec 6;230(4730):1171-3.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3877981" target="_blank"〉PubMed〈/a〉

    Description: The concentration in plasma of the female protein (FP) of the golden Syrian hamster is regulated by sex steroids and by mediators of the acute-phase response to tissue injury or inflammation. A complementary DNA (cDNA) clone corresponding to FP was isolated from a hamster liver cDNA library and used to determine the nucleotide sequence and derived amino acid sequence of native FP. The primary sequence of FP is 69 percent identical to human serum amyloid P component and 50 percent identical to human C-reactive protein. Evidence showed that sex-limited and acute-phase control of the FP gene is pretranslational. The FP protein is thus a useful model for investigating dual regulation of expression of a single gene.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Dowton, S B -- Woods, D E -- Mantzouranis, E C -- Colten, H R -- AI20959/AI/NIAID NIH HHS/ -- New York, N.Y. -- Science. 1985 Jun 7;228(4704):1206-8.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2408337" target="_blank"〉PubMed〈/a〉

    Description: A general method for modifying eukaryotic genes by site-specific mutagenesis and subsequent expression in mammalian cells was developed to study the relation between structure and function of the proteolytic enzyme trypsin. Glycine residues at positions 216 and 226 in the binding cavity of trypsin were replaced by alanine residues, resulting in three trypsin mutants. Computer graphic analysis suggested that these substitutions would differentially affect arginine and lysine substrate binding of the enzyme. Although the mutant enzymes were reduced in catalytic rate, they showed enhanced substrate specificity relative to the native enzyme. This increased specificity was achieved by the unexpected differential effects on the catalytic activity toward arginine and lysine substrates. Mutants containing alanine at position 226 exhibited an altered conformation that may be converted to a trypsin-like structure upon binding of a substrate analog.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Craik, C S -- Largman, C -- Fletcher, T -- Roczniak, S -- Barr, P J -- Fletterick, R -- Rutter, W J -- AM26081/AM/NIADDK NIH HHS/ -- GM07216/GM/NIGMS NIH HHS/ -- GM28520/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1985 Apr 19;228(4697):291-7.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3838593" target="_blank"〉PubMed〈/a〉

A complementary DNA was cloned that corresponds to a gene sequence induced more than 50-fold in a cultured target cell line of pheochromocytoma cells (PC12 cells) 5 hours after the addition of NGF. The induced messenger RNA encodes a 90,000-dalton polypeptide that may represent one of the primary events in NGF-induced differentiation of neurons.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Levi, A -- Eldridge, J D -- Paterson, B M -- New York, N.Y. -- Science. 1985 Jul 26;229(4711):393-5.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3839317" target="_blank"〉PubMed〈/a〉

    Description: A panel of human-mouse somatic cell hybrids and specific complementary DNA probes were used to map the human tissue plasminogen activator and urokinase genes to human chromosomes 8 and 10, respectively. This result is in contrast to a previous assignment of a plasminogen activator gene to chromosome 6. As neoplastic cells produce high levels of plasminogen activator, it is of interest that aberrations of chromosome 8 have been linked to various leukemias and lymphomas and that two human oncogenes, c-mos and c-myc, have also been mapped to chromosome 8.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Rajput, B -- Degen, S F -- Reich, E -- Waller, E K -- Axelrod, J -- Eddy, R L -- Shows, T B -- GM20454/GM/NIGMS NIH HHS/ -- HD05196/HD/NICHD NIH HHS/ -- New York, N.Y. -- Science. 1985 Nov 8;230(4726):672-4.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3840278" target="_blank"〉PubMed〈/a〉

    Description: Plasmodium falciparum, the most lethal of the malarial parasites that infect humans, undergoes three cycles of development in its vertebrate host and elicits stage-specific immune responses. This stage specificity of the immune response has made it difficult to isolate antigens that would be useful in developing a vaccine against malaria. A complementary DNA clone for a glycophorin-binding protein of Plasmodium falciparum merozoites has been isolated and characterized. The protein interacts with glycophorin, the erythrocyte receptor, during invasion of the host cell by the parasite. Antigenic determinants of this protein expressed in Escherichia coli have been used to produce antibodies to a glycophorin-binding protein. The antibodies show schizont-specific immunofluorescence and react with the merozoite protein. The primary sequence of these determinants reveals a 150-nucleotide tandem-repeating sequence coding for a 50-amino-acid repeat. The characterization of the Plasmodium falciparum glycophorin-binding protein represents one approach toward designing serologic agents to block the parasite's development in the vertebrate host.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Ravetch, J V -- Kochan, J -- Perkins, M -- AI19585/AI/NIAID NIH HHS/ -- CA-08748/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 1985 Mar 29;227(4694):1593-7.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3883491" target="_blank"〉PubMed〈/a〉

    Description: Analysis of DNA from human embryo fibroblasts showed that ten Eco RI fragments were hybridizable with the Yamaguchi sarcoma virus oncogene (v-yes). Four of the Eco RI fragments were assigned to chromosome 18 and one to chromosome 6. There was evidence for multiple copies of yes-related genes in the human genome; however, only a single RNA species, 4.8 kilobases in length, was related to yes in various cells.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Semba, K -- Yamanashi, Y -- Nishizawa, M -- Sukegawa, J -- Yoshida, M -- Sasaki, M -- Yamamoto, T -- Toyoshima, K -- New York, N.Y. -- Science. 1985 Mar 1;227(4690):1038-40.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2983418" target="_blank"〉PubMed〈/a〉

    Description: A database useful for mapping the human X chromosome has been established. The data consist of the genotypic characterizations obtained at more than 20 DNA marker loci from a set of 38 selected families. Multilocus linkage analysis has provided an initial genetic map completely spanning the distance from the distal short arm to the distal long arm of the chromosome, for a total genetic length of at least 185 recombination units. Analysis of the recombinational behavior of fully marked chromosomes suggests that the number of recombination events on the X chromosome may be nonrandom. Linkage studies of six families that carry the mutation which causes Duchenne muscular dystrophy were combined with linkage data from a large number of normal families. This permitted mapping of the locus for Duchenne muscular dystrophy with greater precision and statistical confidence than studies in which disease families alone provided the genotypic database. This observation suggests that the normal linkage map of this chromosome should be especially valuable in the mapping of rare X-linked diseases.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Drayna, D -- White, R -- New York, N.Y. -- Science. 1985 Nov 15;230(4727):753-8.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/4059909" target="_blank"〉PubMed〈/a〉

    Description: The amino acid sequence of the glucose transport protein from human HepG2 hepatoma cells was deduced from analysis of a complementary DNA clone. Structural analysis of the purified human erythrocyte glucose transporter by fast atom bombardment mapping and gas phase Edman degradation confirmed the identity of the clone and demonstrated that the HepG2 and erythrocyte transporters are highly homologous and may be identical. The protein lacks a cleavable amino-terminal signal sequence. Analysis of the primary structure suggests the presence of 12 membrane-spanning domains. Several of these may form amphipathic alpha helices and contain abundant hydroxyl and amide side chains that could participate in glucose binding or line a transmembrane pore through which the sugar moves. The amino terminus, carboxyl terminus, and a highly hydrophilic domain in the center of the protein are all predicted to lie on the cytoplasmic face. Messenger RNA species homologous to HepG2 glucose transporter messenger RNA were detected in K562 leukemic cells, HT29 colon adenocarcinoma cells, and human kidney tissue.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Mueckler, M -- Caruso, C -- Baldwin, S A -- Panico, M -- Blench, I -- Morris, H R -- Allard, W J -- Lienhard, G E -- Lodish, H F -- GM22996/GM/NIGMS NIH HHS/ -- HL32262/HL/NHLBI NIH HHS/ -- New York, N.Y. -- Science. 1985 Sep 6;229(4717):941-5.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3839598" target="_blank"〉PubMed〈/a〉
