    Description: A C. elegans neurosecretory signaling system regulates whether animals enter the reproductive life cycle or arrest development at the long-lived dauer diapause stage. daf-2, a key gene in the genetic pathway that mediates this endocrine signaling, encodes an insulin receptor family member. Decreases in DAF-2 signaling induce metabolic and developmental changes, as in mammalian metabolic control by the insulin receptor. Decreased DAF-2 signaling also causes an increase in life-span. Life-span regulation by insulin-like metabolic control is analogous to mammalian longevity enhancement induced by caloric restriction, suggesting a general link between metabolism, diapause, and longevity.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kimura, K D -- Tissenbaum, H A -- Liu, Y -- Ruvkun, G -- R01AG14161/AG/NIA NIH HHS/ -- New York, N.Y. -- Science. 1997 Aug 15;277(5328):942-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Molecular Biology, Massachusetts General Hospital, Boston, MA 02114, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/9252323" target="_blank"〉PubMed〈/a〉

    Description: Prothoracicotropic hormone (PTTH), a brain secretory polypeptide of insects, stimulates the prothoracic glands to produce and release ecdysone, the steroid essential to insect development. The complementary DNAs encoding PTTH of the silkmoth Bombyx mori were cloned and characterized, and the complete amino acid sequence was deduced. The data indicated that PTTH is first synthesized as a 224-amino acid polypeptide precursor containing three proteolytic cleavage signals. The carboxyl-terminal component (109 amino acids) that follows the last cleavage signal represents one PTTH subunit. Two PTTH subunits are linked together by disulfide bonds, before or after cleavage from prepro-PTTH, to form a homodimeric PTTH. When introduced into Escherichia coli cells, the complementary DNA directed the expression of an active substance that was functionally indistinguishable from natural PTTH. In situ hybridization showed the localization of the prepro-PTTH mRNA to two dorsolateral neurosecretory cells of the Bombyx brain.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kawakami, A -- Kataoka, H -- Oka, T -- Mizoguchi, A -- Kimura-Kawakami, M -- Adachi, T -- Iwami, M -- Nagasawa, H -- Suzuki, A -- Ishizaki, H -- New York, N.Y. -- Science. 1990 Mar 16;247(4948):1333-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biology, School of Science, Nagoya University, Japan.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2315701" target="_blank"〉PubMed〈/a〉

    Description: A hallmark of mitosis is the appearance of high levels of histone phosphorylation, yet the roles of these modifications remain largely unknown. Here, we demonstrate that histone H3 phosphorylated at threonine 3 is directly recognized by an evolutionarily conserved binding pocket in the BIR domain of Survivin, which is a member of the chromosomal passenger complex (CPC). This binding mediates recruitment of the CPC to chromosomes and the resulting activation of its kinase subunit Aurora B. Consistently, modulation of the kinase activity of Haspin, which phosphorylates H3T3, leads to defects in the Aurora B-dependent processes of spindle assembly and inhibition of nuclear reformation. These findings establish a direct cellular role for mitotic histone H3T3 phosphorylation, which is read and translated by the CPC to ensure accurate cell division.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3177562/" 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/PMC3177562/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kelly, Alexander E -- Ghenoiu, Cristina -- Xue, John Z -- Zierhut, Christian -- Kimura, Hiroshi -- Funabiki, Hironori -- GM075249/GM/NIGMS NIH HHS/ -- R01 GM075249/GM/NIGMS NIH HHS/ -- R01 GM075249-01/GM/NIGMS NIH HHS/ -- R01 GM075249-02/GM/NIGMS NIH HHS/ -- R01 GM075249-03/GM/NIGMS NIH HHS/ -- R01 GM075249-04/GM/NIGMS NIH HHS/ -- R01 GM075249-05/GM/NIGMS NIH HHS/ -- R01 GM075249-05S1/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2010 Oct 8;330(6001):235-9. doi: 10.1126/science.1189505.

    Description: 13S condensin is a multisubunit protein complex essential for mitotic chromosome condensation in Xenopus egg extracts. Purified 13S condensin introduces positive supercoils into DNA in the presence of topoisomerase I and adenosine triphosphate in vitro. The supercoiling activity of 13Scondensin was regulated by mitosis-specific phosphorylation. Immunodepletion, in vitro phosphorylation, and peptide-mapping experiments indicated that Cdc2 is likely to be the kinase that phosphorylates and activates 13S condensin. Multiple Cdc2 phosphorylation sites are clustered in the carboxyl-terminal domain of the XCAP-D2 (Xenopus chromosome-associated polypeptide D2) subunit. These results suggest that phosphorylation of 13Scondensin by Cdc2 may trigger mitotic chromosome condensation in vitro.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kimura, K -- Hirano, M -- Kobayashi, R -- Hirano, T -- CA45508/CA/NCI NIH HHS/ -- GM53926/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1998 Oct 16;282(5388):487-90.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Cold Spring Harbor Laboratory, Post Office Box 100, 1 Bungtown Road, Cold Spring Harbor, NY 11724, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/9774278" target="_blank"〉PubMed〈/a〉

    Description: The small guanosine triphosphatase Rho is implicated in myosin light chain (MLC) phosphorylation, which results in contraction of smooth muscle and interaction of actin and myosin in nonmuscle cells. The guanosine triphosphate (GTP)-bound, active form of RhoA (GTP.RhoA) specifically interacted with the myosin-binding subunit (MBS) of myosin phosphatase, which regulates the extent of phosphorylation of MLC. Rho-associated kinase (Rho-kinase), which is activated by GTP.RhoA, phosphorylated MBS and consequently inactivated myosin phosphatase. Overexpression of RhoA or activated RhoA in NIH 3T3 cells increased phosphorylation of MBS and MLC. Thus, Rho appears to inhibit myosin phosphatase through the action of Rho-kinase.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kimura, K -- Ito, M -- Amano, M -- Chihara, K -- Fukata, Y -- Nakafuku, M -- Yamamori, B -- Feng, J -- Nakano, T -- Okawa, K -- Iwamatsu, A -- Kaibuchi, K -- New York, N.Y. -- Science. 1996 Jul 12;273(5272):245-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Division of Signal Transduction, Nara Institute of Science and Technology, Ikoma 630-01, Japan.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8662509" target="_blank"〉PubMed〈/a〉

    Description: The substrate-specific protein chaperone Hsp90 (heat shock protein 90) from Saccharomyces cerevisiae functions in diverse signal transduction pathways. A mutation in YDJ1, a member of the DnaJ chaperone family, was recovered in a synthetic-lethal screen with Hsp90 mutants. In an otherwise wild-type background, the ydj1 mutation exerted strong and specific effects on three Hsp90 substrates, derepressing two (the estrogen and glucocorticoid receptors) and reducing the function of the third (the tyrosine kinase p60v-src). Analysis of one of these substrates, the glucocorticoid receptor, indicated that Ydj1 exerts its effects through physical interaction with Hsp90 substrates.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kimura, Y -- Yahara, I -- Lindquist, S -- New York, N.Y. -- Science. 1995 Jun 2;268(5215):1362-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Molecular Genetics and Cell Biology, University of Chicago, IL 60637, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7761857" target="_blank"〉PubMed〈/a〉

    Description: Production of nitric oxide (NO) by macrophages is important for the killing of intracellular infectious agents. Interferon (IFN)-gamma and lipopolysaccharide stimulate NO production by transcriptionally up-regulating the inducible NO synthase (iNOS). Macrophages from mice with a targeted disruption of the IFN regulatory factor-1 (IRF-1) gene (IRF-1-/- mice) produced little or no NO and synthesized barely detectable iNOS messenger RNA in response to stimulation. Two adjacent IRF-1 response elements were identified in the iNOS promoter. Infection with Mycobacterium bovis (BCG) was more severe in IRF-1-/- mice than in wild-type mice. Thus, IRF-1 is essential for iNOS activation in murine macrophages.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kamijo, R -- Harada, H -- Matsuyama, T -- Bosland, M -- Gerecitano, J -- Shapiro, D -- Le, J -- Koh, S I -- Kimura, T -- Green, S J -- A128993/PHS HHS/ -- P30CA13343/CA/NCI NIH HHS/ -- R35CA49731/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 1994 Mar 18;263(5153):1612-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Microbiology, New York University Medical Center, NY 10016.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7510419" target="_blank"〉PubMed〈/a〉

    Description: Poly(ethylene terephthalate) (PET) is used extensively worldwide in plastic products, and its accumulation in the environment has become a global concern. Because the ability to enzymatically degrade PET has been thought to be limited to a few fungal species, biodegradation is not yet a viable remediation or recycling strategy. By screening natural microbial communities exposed to PET in the environment, we isolated a novel bacterium, Ideonella sakaiensis 201-F6, that is able to use PET as its major energy and carbon source. When grown on PET, this strain produces two enzymes capable of hydrolyzing PET and the reaction intermediate, mono(2-hydroxyethyl) terephthalic acid. Both enzymes are required to enzymatically convert PET efficiently into its two environmentally benign monomers, terephthalic acid and ethylene glycol.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Yoshida, Shosuke -- Hiraga, Kazumi -- Takehana, Toshihiko -- Taniguchi, Ikuo -- Yamaji, Hironao -- Maeda, Yasuhito -- Toyohara, Kiyotsuna -- Miyamoto, Kenji -- Kimura, Yoshiharu -- Oda, Kohei -- New York, N.Y. -- Science. 2016 Mar 11;351(6278):1196-9. doi: 10.1126/science.aad6359.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Applied Biology, Faculty of Textile Science, Kyoto Institute of Technology, Matsugasaki, Sakyo-ku, Kyoto 606-8585, Japan.

    Description: Myelin basic proteins (MBPs) are coded by the single gene necessary for myelin formation in the central nervous system of the mouse. An antisense MBP mini-gene was constructed and used to determine the function of antisense DNA in transgenic mice. Several transgenic offspring of a founder transgenic mouse, AS100, were converted from the normal to mutant shiverer phenotype. Antisense MBP messenger RNA was expressed in these mice, and the endogenous MBP messenger RNA, the MBP, and the myelination in the central nervous system were reduced.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Katsuki, M -- Sato, M -- Kimura, M -- Yokoyama, M -- Kobayashi, K -- Nomura, T -- New York, N.Y. -- Science. 1988 Jul 29;241(4865):593-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of DNA Biology, School of Medicine, Tokai University, Isehara, Japan.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2456614" target="_blank"〉PubMed〈/a〉
