    Description: Insulin-like growth factor 1 (IGF-1) induces skeletal muscle maturation and enlargement (hypertrophy). These responses require protein synthesis and myofibril formation (myofibrillogenesis). However, the signaling mechanisms of myofibrillogenesis remain obscure. We found that IGF-1-induced phosphatidylinositol 3-kinase-Akt signaling formed a complex of nebulin and N-WASP at the Z bands of myofibrils by interfering with glycogen synthase kinase-3beta in mice. Although N-WASP is known to be an activator of the Arp2/3 complex to form branched actin filaments, the nebulin-N-WASP complex caused actin nucleation for unbranched actin filament formation from the Z bands without the Arp2/3 complex. Furthermore, N-WASP was required for IGF-1-induced muscle hypertrophy. These findings present the mechanisms of IGF-1-induced actin filament formation in myofibrillogenesis required for muscle maturation and hypertrophy and a mechanism of actin nucleation.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Takano, Kazunori -- Watanabe-Takano, Haruko -- Suetsugu, Shiro -- Kurita, Souichi -- Tsujita, Kazuya -- Kimura, Sumiko -- Karatsu, Takashi -- Takenawa, Tadaomi -- Endo, Takeshi -- New York, N.Y. -- Science. 2010 Dec 10;330(6010):1536-40. doi: 10.1126/science.1197767.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biology, Graduate School of Science, Chiba University, 1-33 Yayoicho, Inageku, Chiba 263-8522, Japan.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/21148390" 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: A switchlike response in nuclear factor-kappaB (NF-kappaB) activity implies the existence of a threshold in the NF-kappaB signaling module. We show that the CARD-containing MAGUK protein 1 (CARMA1, also called CARD11)-TAK1 (MAP3K7)-inhibitor of NF-kappaB (IkappaB) kinase-beta (IKKbeta) module is a switch mechanism for NF-kappaB activation in B cell receptor (BCR) signaling. Experimental and mathematical modeling analyses showed that IKK activity is regulated by positive feedback from IKKbeta to TAK1, generating a steep dose response to BCR stimulation. Mutation of the scaffolding protein CARMA1 at serine-578, an IKKbeta target, abrogated not only late TAK1 activity, but also the switchlike activation of NF-kappaB in single cells, suggesting that phosphorylation of this residue accounts for the feedback.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Shinohara, Hisaaki -- Behar, Marcelo -- Inoue, Kentaro -- Hiroshima, Michio -- Yasuda, Tomoharu -- Nagashima, Takeshi -- Kimura, Shuhei -- Sanjo, Hideki -- Maeda, Shiori -- Yumoto, Noriko -- Ki, Sewon -- Akira, Shizuo -- Sako, Yasushi -- Hoffmann, Alexander -- Kurosaki, Tomohiro -- Okada-Hatakeyama, Mariko -- 5R01CA141722/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 2014 May 16;344(6185):760-4. doi: 10.1126/science.1250020.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Laboratory for Integrated Cellular Systems, RIKEN Center for Integrative Medical Sciences (IMS-RCAI), Tsurumi-ku, Yokohama, Kanagawa 230-0045, Japan. ; Signaling Systems Laboratory, Department of Chemistry and Biochemistry, University of California, San Diego, La Jolla, CA 92093, USA.

    Description: Although interferon (IFN) signaling induces genes that limit viral infection, many pathogenic viruses overcome this host response. As an example, 2'-O methylation of the 5' cap of viral RNA subverts mammalian antiviral responses by evading restriction of Ifit1, an IFN-stimulated gene that regulates protein synthesis. However, alphaviruses replicate efficiently in cells expressing Ifit1 even though their genomic RNA has a 5' cap lacking 2'-O methylation. We show that pathogenic alphaviruses use secondary structural motifs within the 5' untranslated region (UTR) of their RNA to alter Ifit1 binding and function. Mutations within the 5'-UTR affecting RNA structural elements enabled restriction by or antagonism of Ifit1 in vitro and in vivo. These results identify an evasion mechanism by which viruses use RNA structural motifs to avoid immune restriction.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4209899/" 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/PMC4209899/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hyde, Jennifer L -- Gardner, Christina L -- Kimura, Taishi -- White, James P -- Liu, Gai -- Trobaugh, Derek W -- Huang, Cheng -- Tonelli, Marco -- Paessler, Slobodan -- Takeda, Kiyoshi -- Klimstra, William B -- Amarasinghe, Gaya K -- Diamond, Michael S -- AI049820/AI/NIAID NIH HHS/ -- P41GM66326/GM/NIGMS NIH HHS/ -- P41RR02301/RR/NCRR NIH HHS/ -- R01 AI083383/AI/NIAID NIH HHS/ -- R01 AI104972/AI/NIAID NIH HHS/ -- U19 AI083019/AI/NIAID NIH HHS/ -- UL1 TR000071/TR/NCATS NIH HHS/ -- UL1TR000071/TR/NCATS NIH HHS/ -- New York, N.Y. -- Science. 2014 Feb 14;343(6172):783-7. doi: 10.1126/science.1248465.

    Description: A protein that may be an enkephalin precursor has been identified in extracts of bovine adrenal medulla. This protein (about 50,000 daltons) appears to contain seven copies of [Met]enkephalin and one copy of [Leu]enkephalin. Digestion with trypsin and carboxypeptidase B yields [Met]enkephalin and [Leu]enkephalin in a ratio of almost 7 to 1. The enkephalins were identified by chromatography and by their binding to opiate receptors. Some characteristics of several other adrenal peptides that may serve as intermediates in the biosynthesis of the enkephalins are presented.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lewis, R V -- Stern, A S -- Kimura, S -- Rossier, J -- Stein, S -- Udenfriend, S -- New York, N.Y. -- Science. 1980 Jun 27;208(4451):1459-61.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7384787" target="_blank"〉PubMed〈/a〉

    Description: Choline acetyltransferase was demonstrated in neuronal structures of the rodent central nervous system by immunohistochemistry through the application of Fab fragments obtained from monospecific antiserums to human choline acetyltransferase. The specificity of the antiserum for the enzyme was confirmed by the staining of both the ventral horn motor neurons in the rat spinal cord and the neuromuscular junction of the guinea pig diaphragm. Enzyme-containing cell bodies were observed in frontal sections of rat and guinea pig brain in the neostriatum, accumbens, nucleus of the diagonal band, medial septum, and olfactory tubercle. Positively staining fibers and probable nerve terminals were also found in the olfactory tubercle field and other areas of the basal forebrain. The results provide information on the distribution of the cholinergic systems in the rostral forebrain of the rodent.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kimura, H -- McGeer, P L -- Peng, F -- McGeer, E G -- New York, N.Y. -- Science. 1980 May 30;208(4447):1057-9.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6990490" target="_blank"〉PubMed〈/a〉
