    Identification of specific transducin alpha subunits in retinal rod and cone photoreceptors (1986)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1986-10-03
    Description: Transducin is a guanyl nucleotide-binding protein that couples rhodopsin photolysis to hydrolysis of guanosine 3',5'-monophosphate in rod photoreceptor cells of vertebrate retinas. Several complementary DNA clones encoding transducin subunits have recently been characterized. One clone, isolated from a bovine retina complementary DNA library, encodes a previously unidentified polypeptide with an amino acid sequence 78% identical to the sequence of the alpha subunit of bovine rod outer segment transducin. Antibodies to a synthetic peptide with amino acid sequence derived specifically from this novel polypeptide recognize a 41-kilodalton polypeptide in homogenates of bovine retina. Localization of this polypeptide in bovine retina by indirect immunofluorescence demonstrates that it is expressed only in cone outer segments. Antibodies to specific sequences found only in the rod transducin alpha subunit recognize a polypeptide localized only in the rod outer segment. Therefore, bovine rod and cone cells each express structurally related yet significantly different forms of transducin.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lerea, C L -- Somers, D E -- Hurley, J B -- Klock, I B -- Bunt-Milam, A H -- EYO 1311/EY/NEI NIH HHS/ -- EYO 1730/EY/NEI NIH HHS/ -- New York, N.Y. -- Science. 1986 Oct 3;234(4772):77-80.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3529395" target="_blank"〉PubMed〈/a〉

    Structural heterogeneity and functional domains of murine immunoglobulin G Fc receptors (1986)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1986-11-07
    Description: Binding of antibodies to effector cells by way of receptors to their constant regions (Fc receptors) is central to the pathway that leads to clearance of antigens by the immune system. The structure and function of this important class of receptors on immune cells is addressed through the molecular characterization of Fc receptors (FcR) specific for the murine immunoglobulin G isotype. Structural diversity is encoded by two genes that by alternative splicing result in expression of molecules with highly conserved extracellular domains and different transmembrane and intracytoplasmic domains. The proteins encoded by these genes are members of the immunoglobulin supergene family, most homologous to the major histocompatibility complex molecule E beta. Functional reconstitution of ligand binding by transfection of individual FcR genes demonstrates that the requirements for ligand binding are encoded in a single gene. These studies demonstrate the molecular basis for the functional heterogeneity of FcR's, accounting for the possible transduction of different signals in response to a single ligand.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Ravetch, J V -- Luster, A D -- Weinshank, R -- Kochan, J -- Pavlovec, A -- Portnoy, D A -- Hulmes, J -- Pan, Y C -- Unkeless, J C -- AI 24322/AI/NIAID NIH HHS/ -- GM 36306/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1986 Nov 7;234(4777):718-25.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2946078" target="_blank"〉PubMed〈/a〉

    Tandem duplication of D-loop and ribosomal RNA sequences in lizard mitochondrial DNA (1986)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1986-09-26
    Description: Some Cnemidophorus exsanguis have mitochondrial DNA's (mtDNA's) that are 22.2 kilobases (kb) in size, whereas most have mtDNA's of 17.4 kb. Restriction site mapping, DNA transfer hybridization experiments, and electron microscopy show that the size increment stems from the tandem duplication of a 4.8-kb region that includes regulatory sequences and transfer and ribosomal RNA genes. This observation is notable in that sequences outside of the control region are involved in major length variation. Besides revealing a novel form of mtDNA evolution in animals, these duplications provide a useful system for investigating the molecular and evolutionary biology of animal mtDNA.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Moritz, C -- Brown, W M -- GM30144/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1986 Sep 26;233(4771):1425-7.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3018925" target="_blank"〉PubMed〈/a〉

    Equine infectious anemia virus gag and pol genes: relatedness to visna and AIDS virus (1986)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1986-02-07
    Description: Comparison of HTLV-III, the putative AIDS virus, with other related viruses, may help to reveal more about the origin of AIDS in humans. In this study, the nucleotide sequence of the gag and pol genes of an equine infectious anemia virus (EIAV) proviral DNA clone was determined. The sequence was compared with that of HTLV-III and of visna, a pathogenic lentivirus of sheep. The results show that these viruses constitute a family clearly distinct from that of the type C viruses or the BLV-HTLV-I and -II group. Within the family, EIAV, HTLV-III, and visna appear to be equally divergent from a common evolutionary ancestor.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Stephens, R M -- Casey, J W -- Rice, N R -- N0I-C-23909/PHS HHS/ -- New York, N.Y. -- Science. 1986 Feb 7;231(4738):589-94.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3003905" target="_blank"〉PubMed〈/a〉

    Identification and characterization of the protein encoded by the human N-myc oncogene (1986)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1986-05-09
    Description: The human N-myc gene is related to the c-myc proto-oncogene, and has been shown to have transforming potential in vitro. Many studies have reported amplification of N-myc in human neuroblastoma and retinoblastoma cell lines. In primary tumors, amplification of the gene was found to correlate directly with behavior of the tumor. Specific restriction fragments of a partial complementary DNA clone of N-myc from LA-N-5 human neuroblastoma cells were placed into a bacterial expression vector for the purpose of producing antigens representative of the N-myc protein. Rabbits immunized with these antigens produced antisera that recognized a protein of 62-64 kilodaltons in neuroblastoma cells. By several criteria, this protein appears to be part of the same proto-oncogene family as the c-myc protein. Moreover, the antisera to fragments of this protein were capable of histochemically identifying malignant cells in clinical specimens.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Slamon, D J -- Boone, T C -- Seeger, R C -- Keith, D E -- Chazin, V -- Lee, H C -- Souza, L M -- CA 16042/CA/NCI NIH HHS/ -- CA 36827/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 1986 May 9;232(4751):768-72.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3008339" target="_blank"〉PubMed〈/a〉

    The 35-nucleotide spliced leader sequence is common to all trypanosome messenger RNA's (1986)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1986-08-01
    Description: In Trypanosomatidae the messenger RNA's (mRNA's) that code for the variant surface glycoproteins (VSG's), tubulins, calmodulin, and at least a subset of other proteins contain a common 35-nucleotide leader sequence at their 5' ends. Hybrid-arrested in vitro translation has been used to show that all mRNA's in both African and South American trypanosomes contain this 35-nucleotide sequence. Oligonucleotides complementary to this sequence blocked translation of all trypanosome mRNA's in a rabbit reticulocyte lysate system, but did not inhibit translation of mRNA's from other organisms lacking this sequence. An oligonucleotide complementary to the VSG mRNA downstream from the spliced leader sequence arrested only VSG synthesis. Thus, the 35-nucleotide leader sequence is a general feature of all trypanosome mRNA's. The high specificity of oligonucleotides complementary to the spliced leader for their target sequence suggests that analogues permeable to the cell membrane may be useful in the treatment of trypanosomal infections.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Walder, J A -- Eder, P S -- Engman, D M -- Brentano, S T -- Walder, R Y -- Knutzon, D S -- Dorfman, D M -- Donelson, J E -- AI-18954/AI/NIAID NIH HHS/ -- AM-25295/AM/NIADDK NIH HHS/ -- HL-33555/HL/NHLBI NIH HHS/ -- etc. -- New York, N.Y. -- Science. 1986 Aug 1;233(4763):569-71.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3523758" target="_blank"〉PubMed〈/a〉

    Deletion in cysteine-rich region of LDL receptor impedes transport to cell surface in WHHL rabbit (1986)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1986-06-06
    Description: The Watanabe heritable hyperlipidemic (WHHL) rabbit, an animal with familial hypercholesterolemia, produces a mutant receptor for plasma low-density lipoprotein (LDL) that is not transported to the cell surface at a normal rate. Cloning and sequencing of complementary DNA's from normal and WHHL rabbits, shows that this defect arises from an in-frame deletion of 12 nucleotides that eliminates four amino acids from the cysteine-rich ligand binding domain of the LDL receptor. A similar mutation, detected by S1 nuclease mapping of LDL receptor messenger RNA, occurred in a patient with familial hypercholesterolemia whose receptor also fails to be transported to the cell surface. These findings suggest that animal cells may have fail-safe mechanisms that prevent the surface expression of improperly folded proteins with unpaired or improperly bonded cysteine residues.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4451858/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4451858/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Yamamoto, T -- Bishop, R W -- Brown, M S -- Goldstein, J L -- Russell, D W -- HL 01287/HL/NHLBI NIH HHS/ -- HL 20948/HL/NHLBI NIH HHS/ -- HL 31346/HL/NHLBI NIH HHS/ -- P01 HL020948/HL/NHLBI NIH HHS/ -- New York, N.Y. -- Science. 1986 Jun 6;232(4755):1230-7.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3010466" target="_blank"〉PubMed〈/a〉

    Activation of mouse T-helper cells induces abundant preproenkephalin mRNA synthesis (1986)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1986-05-09
    Description: Antigenic or mitogenic stimulation of T cells induces the secretion of an array of protein hormones that regulate immune responses. Molecular cloning has contributed strongly to our present understanding of the nature of this regulation. A complementary DNA (cDNA) library prepared from a cloned concanavalin A-activated mouse T-helper cell line was screened for abundant and induction-specific cDNA's. One such randomly chosen cDNA was found to encode mouse preproenkephalin messenger RNA (mRNA). Preproenkephalin mRNA represented about 0.4 percent of the mRNA in the activated cell line but was absent in resting cells of this line. Other induced T-helper cell lines have 0.1 to 0.5 percent of their mRNA as preproenkephalin mRNA. Induced T-helper cell culture supernatants have [Met]enkephalin-immunoreactive material. The production by activated T cells of a peptide neurotransmitter identifies a signal that can potentially permit T cells to modulate the nervous system.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Zurawski, G -- Benedik, M -- Kamb, B J -- Abrams, J S -- Zurawski, S M -- Lee, F D -- New York, N.Y. -- Science. 1986 May 9;232(4751):772-5.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2938259" target="_blank"〉PubMed〈/a〉

    T-cell recognition of Ia molecules selectively altered by a single amino acid substitution (1986)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1986-01-17
    Description: T lymphocytes recognize foreign antigen together with allele-specific determinants on membrane-bound class I and class II (Ia) gene products of the major histocompatibility complex. To identify amino acids of class II molecules critical to this recognition process, the genes encoding the beta chains of the I-Ak molecule were cloned from a wild-type B-cell hybridoma and from an immunoselected variant subline showing distinct serological and T-cell stimulatory properties. Nucleotide sequencing and DNA-mediated gene transfer established that a single base transition (G----A) encoding a change from glutamic acid to lysine at position 67 in the I-Ak beta molecule accounted for all the observed phenotypic changes of the variant cells. These results confirm the importance of residues 62 to 78 in the amino terminal domain of I-A beta for class II-restricted T-cell recognition of antigen and demonstrate the ability of a single substitution in this region to alter this recognition event.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Brown, M A -- Glimcher, L A -- Nielsen, E A -- Paul, W E -- Germain, R N -- New York, N.Y. -- Science. 1986 Jan 17;231(4735):255-8.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3484558" target="_blank"〉PubMed〈/a〉

    A yeast gene that is essential for release from glucose repression encodes a protein kinase (1986)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1986-09-12
    Description: The SNF1 gene plays a central role in carbon catabolite repression in the yeast Saccharomyces cerevisiae, namely that SNF1 function is required for expression of glucose-repressible genes. The nucleotide sequence of the cloned SNF1 gene was determined, and the predicted amino acid sequence shows that SNF1 encodes a 72,040-dalton polypeptide that has significant homology to the conserved catalytic domain of mammalian protein kinases. Specific antisera were prepared and used to identify the SNF1 protein. The protein was shown to transfer phosphate from adenosine triphosphate to serine and threonine residues in an in vitro autophosphorylation reaction. These findings indicate that SNF1 encodes a protein kinase and suggest that protein phosphorylation plays a critical role in regulation by carbon catabolite repression in eukaryotic cells.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Celenza, J L -- Carlson, M -- GM34095/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1986 Sep 12;233(4769):1175-80.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3526554" target="_blank"〉PubMed〈/a〉
