    Rel-associated pp40: an inhibitor of the rel family of transcription factors (1991)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1991-09-23
    Beschreibung: 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〉

    Presence of an SH2 domain in the actin-binding protein tensin (1991)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1991-05-03
    Beschreibung: 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
    Publikationsdatum: 1991-07-05
    Beschreibung: 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〉

    Arabidopsis and Nicotiana anthocyanin production activated by maize regulators R and C1 (1992)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1992-12-11
    Beschreibung: Anthocyanin pathway-specific transcriptional activators R and C1 from the monocot maize were expressed in two dicots, Arabidopsis thaliana and Nicotiana tabacum. Expression of R caused augmented anthocyanin pigmentation in both plant species and augmented trichome (hair) production in Arabidopsis. Alone, C1 had no effect. Hybrid transgenic Arabidopsis expressing both C1 and R produced anthocyanins in root, petal, and stamen tissues that normally never express anthrocyanins. When R was expressed in the transparent testa glabrous (without anthocyanins and trichomes) mutant of Arabidopsis, the deficiency was complemented and both anthocyanins and trichomes were restored.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lloyd, A M -- Walbot, V -- Davis, R W -- GM 32422/GM/NIGMS NIH HHS/ -- R37-H600198/PHS HHS/ -- New York, N.Y. -- Science. 1992 Dec 11;258(5089):1773-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biochemistry, Stanford University, CA 94305.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/1465611" target="_blank"〉PubMed〈/a〉

    Low affinity interaction of peptide-MHC complexes with T cell receptors (1991)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1991-12-20
    Beschreibung: The interaction of antigen-specific T cell receptors (TCRs) with their ligands, peptides bound to molecules of the major histocompatibility complex (MHC), is central to most immune responses, yet little is known about its chemical characteristics. The binding to T cells of a labeled monoclonal antibody to the TCR was inhibited by soluble class II MHC heterodimers complexed to different peptides. Inhibition was both peptide- and TCR-specific and of low affinity, with a KD = 4 x 10(-5) to 6 x 10(-5) M, orders of magnitude weaker than comparable antibody-antigen interactions. This finding is consistent with the scanning nature of T cell recognition and suggests that antigen-independent adhesion precedes TCR engagement.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Matsui, K -- Boniface, J J -- Reay, P A -- Schild, H -- Fazekas de St Groth, B -- Davis, M M -- AI19512/AI/NIAID NIH HHS/ -- New York, N.Y. -- Science. 1991 Dec 20;254(5039):1788-91.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Howard Hughes Medical Institute, Stanford, CA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/1763329" target="_blank"〉PubMed〈/a〉

    Invariant chain peptides in most HLA-DR molecules of an antigen-processing mutant (1992)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1992-12-11
    Beschreibung: Class II major histocompatibility complexes bind peptides in an endosome-like compartment. When the class II null cell line 721.174 was transfected with class II DR3 genes, DR molecules were produced in normal amounts. However, the DR molecules were abnormally conformed and unstable because deletion of an antigen-processing gene had impaired intracellular formation of most class II-peptide complexes. Yet, 70 percent of the DR molecules still bore peptides, 80 percent of which were 21- to 24-amino acid fragments of the class II-associated invariant chain. These peptides were rare on DR3 from control cells. Thus, a defect in the main antigen-processing pathway revealed a process in which DR molecules bind long peptides derived from proteins present in the same compartment.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Sette, A -- Ceman, S -- Kubo, R T -- Sakaguchi, K -- Appella, E -- Hunt, D F -- Davis, T A -- Michel, H -- Shabanowitz, J -- Rudersdorf, R -- AI15486/AI/NIAID NIH HHS/ -- AI18634/AI/NIAID NIH HHS/ -- GM37537/GM/NIGMS NIH HHS/ -- etc. -- New York, N.Y. -- Science. 1992 Dec 11;258(5089):1801-4.〈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/1465617" target="_blank"〉PubMed〈/a〉

    Acquisition of myogenic specificity by replacement of three amino acid residues from MyoD into E12 (1992)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1992-05-15
    Beschreibung: The basic helix-loop-helix (bHLH) protein MyoD is a transcription factor that is important for the induction of the myogenic phenotype. The DNA binding basic region (13 amino acids) is necessary for recognition of the consensus MyoD binding site, for transcriptional activation, and for conversion of fibroblasts to muscle. In contrast, the non-tissue-specific bHLH protein E12 can bind to the MyoD binding site but does not induce myogenesis. Here, it is shown that only two amino acids in the MyoD basic region and a single amino acid from the junction, which separates the basic region and helix 1, are sufficient for myogenic specificity when substituted into the corresponding region of E12. These findings suggest that the recognition of particular determinants in the basic region is required for conversion of fibroblasts to muscle.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Davis, R L -- Weintraub, H -- New York, N.Y. -- Science. 1992 May 15;256(5059):1027-30.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Howard Hughes Medical Institute Laboratory, 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/1317057" target="_blank"〉PubMed〈/a〉
