    Induction of apoptosis by ASK1, a mammalian MAPKKK that activates SAPK/JNK and p38 signaling pathways (1997)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1997-01-03
    Description: Mitogen-activated protein (MAP) kinase cascades are activated in response to various extracellular stimuli, including growth factors and environmental stresses. A MAP kinase kinase kinase (MAPKKK), termed ASK1, was identified that activated two different subgroups of MAP kinase kinases (MAPKK), SEK1 (or MKK4) and MKK3/MAPKK6 (or MKK6), which in turn activated stress-activated protein kinase (SAPK, also known as JNK; c-Jun amino-terminal kinase) and p38 subgroups of MAP kinases, respectively. Overexpression of ASK1 induced apoptotic cell death, and ASK1 was activated in cells treated with tumor necrosis factor-alpha (TNF-alpha). Moreover, TNF-alpha-induced apoptosis was inhibited by a catalytically inactive form of ASK1. ASK1 may be a key element in the mechanism of stress- and cytokine-induced apoptosis.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Ichijo, H -- Nishida, E -- Irie, K -- ten Dijke, P -- Saitoh, M -- Moriguchi, T -- Takagi, M -- Matsumoto, K -- Miyazono, K -- Gotoh, Y -- New York, N.Y. -- Science. 1997 Jan 3;275(5296):90-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biochemistry, The Cancer Institute, Tokyo, Japanese Foundation for Cancer Research, 1-37-1 Kami-Ikebukuro, Toshima-ku, Tokyo 170, Japan.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8974401" target="_blank"〉PubMed〈/a〉

    Microtubule severing by elongation factor 1 alpha (1994)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1994-10-14
    Description: An activity that severs stable microtubules is thought to be involved in microtubule reorganization during the cell cycle. Here, a 48-kilodalton microtubule-severing protein was purified from Xenopus eggs and identified as translational elongation factor 1 alpha (EF-1 alpha). Bacterially expressed human EF-1 alpha also displayed microtubule-severing activity in vitro and, when microinjected into fibroblasts, induced rapid and transient fragmentation of cytoplasmic microtubule arrays. Thus, EF-1 alpha, an essential component of the eukaryotic translational apparatus, appears to have a second role as a regulator of cytoskeletal rearrangements.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Shiina, N -- Gotoh, Y -- Kubomura, N -- Iwamatsu, A -- Nishida, E -- New York, N.Y. -- Science. 1994 Oct 14;266(5183):282-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Genetics and Molecular Biology, Kyoto University, Japan.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7939665" target="_blank"〉PubMed〈/a〉

    Crystal Structure of the High-Pressure Phase of Solid CO2 (1994)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1994-01-21
    Description: X-ray diffraction study of solid CO(2) at room temperature has shown that the powder pattern of the high-pressure phase, which supersedes the low-pressure cubic Pa3 phase at about 10 gigapascals, is consistently interpreted in terms of an orthorhombic Cmca structure. The orthorhombic cell at 11.8 gigapascals has dimensions of 4.330 +/- 0.015, 4.657 +/- 0.005, 5.963 +/- 0.009 angstroms for its a, b, and c faces, respectively, and a volume of 120.3 +/- 0.5 cubic angstroms. Four molecules contained in the unit cell are located at the base-centered positions with their molecular axes inclined at about 52 degrees with respect to the crystallographic c axis. The volume change associated with the Pa3-Cmca transition is close to zero. The structural dimensions obtained for the high-pressure crystalline phase of CO(2) are of great importance for a theoretical understanding of the role of intermolecular interactions, including quadrupole-quadrupole interactions, in molecular condensation.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Aoki, K -- Yamawaki, H -- Sakashita, M -- Gotoh, Y -- Takemura, K -- New York, N.Y. -- Science. 1994 Jan 21;263(5145):356-8.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17769798" target="_blank"〉PubMed〈/a〉

    TAB1: an activator of the TAK1 MAPKKK in TGF-beta signal transduction (1996)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1996-05-24
    Description: Transforming growth factor-beta (TGF-beta) regulates many aspects of cellular function. A member of the mitogen-activated protein kinase kinase kinase (MAPKKK) family, TAK1, was previously identified as a mediator in the signaling pathway of TGF-beta superfamily members. The yeast two-hybrid system has now revealed two human proteins, termed TAB1 and TAB2 (for TAK1 binding protein), that interact with TAK1. TAB1 and TAK1 were co-immunoprecipitated from mammalian cells. Overproduction of TAB1 enhanced activity of the plasminogen activator inhibitor 1 gene promoter, which is regulated by TGF-beta, and increased the kinase activity of TAK1. TAB1 may function as an activator of the TAK1 MAPKKK in TGF-beta signal transduction.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Shibuya, H -- Yamaguchi, K -- Shirakabe, K -- Tonegawa, A -- Gotoh, Y -- Ueno, N -- Irie, K -- Nishida, E -- Matsumoto, K -- New York, N.Y. -- Science. 1996 May 24;272(5265):1179-82.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Faculty of Pharmaceutical Sciences, Hokkaido University, Sapporo, Japan.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8638164" target="_blank"〉PubMed〈/a〉

    Activation of the estrogen receptor through phosphorylation by mitogen-activated protein kinase (1995)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1995-12-01
    Description: The phosphorylation of the human estrogen receptor (ER) serine residue at position 118 is required for full activity of the ER activation function 1 (AF-1). This Ser118 is phosphorylated by mitogen-activated protein kinase (MAPK) in vitro and in cells treated with epidermal growth factor (EGF) and insulin-like growth factor (IGF) in vivo. Overexpression of MAPK kinase (MAPKK) or of the guanine nucleotide binding protein Ras, both of which activate MAPK, enhanced estrogen-induced and antiestrogen (tamoxifen)-induced transcriptional activity of wild-type ER, but not that of a mutant ER with an alanine in place of Ser118. Thus, the activity of the amino-terminal AF-1 of the ER is modulated by the phosphorylation of Ser118 through the Ras-MAPK cascade of the growth factor signaling pathways.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kato, S -- Endoh, H -- Masuhiro, Y -- Kitamoto, T -- Uchiyama, S -- Sasaki, H -- Masushige, S -- Gotoh, Y -- Nishida, E -- Kawashima, H -- Metzger, D -- Chambon, P -- New York, N.Y. -- Science. 1995 Dec 1;270(5241):1491-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Agricultural Chemistry, Tokyo University of Agriculture, Japan.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7491495" target="_blank"〉PubMed〈/a〉

    Stimulatory effects of yeast and mammalian 14-3-3 proteins on the Raf protein kinase (1994)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1994-09-16
    Description: Intracellular signaling from receptor tyrosine kinases in mammalian cells results in activation of a signal cascade that includes the guanine nucleotide-binding protein Ras and the protein kinases Raf, MEK [mitogen-activated protein kinase (MAPK) or extracellular signal-regulated kinase (ERK) kinase], and MAPK. MAPK activation that is dependent on the coupling of Ras and Raf was reconstituted in yeast. Yeast genes were isolated that, when overexpressed, enhanced the function of Raf. One of them is identical to BMH1, which encodes a protein similar to members of the mammalian 14-3-3 family. Bacterially synthesized mammalian 14-3-3 protein stimulated the activity of Raf prepared from yeast cells expressing c-Raf-1. Thus, the 14-3-3 protein may participate in or be required for activation of Raf.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Irie, K -- Gotoh, Y -- Yashar, B M -- Errede, B -- Nishida, E -- Matsumoto, K -- New York, N.Y. -- Science. 1994 Sep 16;265(5179):1716-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Molecular Biology, Faculty of Science, Nagoya University, Japan.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8085159" target="_blank"〉PubMed〈/a〉

    Introduction of H-antigens into oligosaccharides and sugar chains of glycoproteins using highly efficient 1,2-{alpha}-L-fucosynthase (2016)
    Oxford University Press
    Details
    Publication Date: 2016-12-02
    Description: Fucα1-2 Gal linkages, or H-antigens, constitute histo-blood group antigens and are involved in various physiological processes. In addition, recent studies have shown that the H-antigen-containing glycans play an important role, not only in establishing harmonious relationship between gut microbes and the host, but also in preventing gut dysbiosis-related diseases. Therefore, development of an efficient method for introducing Fuc residue at Gal residue at the nonreducing end of glycans via α-(1-〉2) linkage is desired for research as well as medicinal purposes. In this study, we succeeded in derivatizing inverting 1,2-α- l -fucosidase (AfcA) into a highly efficient 1,2-α- l -fucosynthase. The synthase specifically synthesized H type 1-, type 2-, type 3- and type 4-chain-containing oligosaccharides with yields of 57–75% based on acceptor depletion. The synthase was also able to specifically introduce Fuc residues into Lewis a/x antigens to produce Lewis b/y antigens, with yields of 43% and 62%, respectively. In addition, the enzyme efficiently introduced H-antigens into sugar chains of porcine gastric mucins, as revealed by lectin blotting and mass spectroscopy analysis of the sugars. Detailed acceptor specificity analysis using various monosaccharides and oligosaccharides unraveled unique substrate recognition feature of this synthase at the subsite (+1), which can be explained by our previous X-ray crystallographic study of AfcA. These results show that the synthase developed in this study could serve as an alternative to other H-antigen synthesis methods involving α-1,2-fucosyltransferases and retaining α-fucosidase.
