    Virus-enabled synthesis and assembly of nanowires for lithium ion battery electrodes (2006)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2006-04-08
    Description: The selection and assembly of materials are central issues in the development of smaller, more flexible batteries. Cobalt oxide has shown excellent electrochemical cycling properties and is thus under consideration as an electrode for advanced lithium batteries. We used viruses to synthesize and assemble nanowires of cobalt oxide at room temperature. By incorporating gold-binding peptides into the filament coat, we formed hybrid gold-cobalt oxide wires that improved battery capacity. Combining virus-templated synthesis at the peptide level and methods for controlling two-dimensional assembly of viruses on polyelectrolyte multilayers provides a systematic platform for integrating these nanomaterials to form thin, flexible lithium ion batteries.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Nam, Ki Tae -- Kim, Dong-Wan -- Yoo, Pil J -- Chiang, Chung-Yi -- Meethong, Nonglak -- Hammond, Paula T -- Chiang, Yet-Ming -- Belcher, Angela M -- New York, N.Y. -- Science. 2006 May 12;312(5775):885-8.

    BSKs mediate signal transduction from the receptor kinase BRI1 in Arabidopsis (2008)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2008-07-26
    Description: Brassinosteroids (BRs) bind to the extracellular domain of the receptor kinase BRI1 to activate a signal transduction cascade that regulates nuclear gene expression and plant development. Many components of the BR signaling pathway have been identified and studied in detail. However, the substrate of BRI1 kinase that transduces the signal to downstream components remains unknown. Proteomic studies of plasma membrane proteins lead to the identification of three homologous BR-signaling kinases (BSK1, BSK2, and BSK3). The BSKs are phosphorylated by BRI1 in vitro and interact with BRI1 in vivo. Genetic and transgenic studies demonstrate that the BSKs represent a small family of kinases that activate BR signaling downstream of BRI1. These results demonstrate that BSKs are the substrates of BRI1 kinase that activate downstream BR signal transduction.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2730546/" 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/PMC2730546/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Tang, Wenqiang -- Kim, Tae-Wuk -- Oses-Prieto, Juan A -- Sun, Yu -- Deng, Zhiping -- Zhu, Shengwei -- Wang, Ruiju -- Burlingame, Alma L -- Wang, Zhi-Yong -- R01 GM066258/GM/NIGMS NIH HHS/ -- R01 GM066258-07/GM/NIGMS NIH HHS/ -- R01GM066258/GM/NIGMS NIH HHS/ -- RR012961/RR/NCRR NIH HHS/ -- RR01614/RR/NCRR NIH HHS/ -- RR019934/RR/NCRR NIH HHS/ -- New York, N.Y. -- Science. 2008 Jul 25;321(5888):557-60. doi: 10.1126/science.1156973.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Plant Biology, Carnegie Institution of Washington, Stanford, CA 94305, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/18653891" target="_blank"〉PubMed〈/a〉

    A molecular determinant for the establishment of sister chromatid cohesion (2008)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2008-07-26
    Description: Chromosome segregation, transcriptional regulation, and repair of DNA double-strand breaks require the cohesin protein complex. Cohesin holds the replicated chromosomes (sister chromatids) together to mediate sister chromatid cohesion. The mechanism of how cohesion is established is unknown. We found that in budding yeast, the head domain of the Smc3p subunit of cohesin is acetylated by the Eco1p acetyltransferase at two evolutionarily conserved residues, promoting the chromatin-bound cohesin to tether sister chromatids. Smc3p acetylation is induced in S phase after the chromatin loading of cohesin and is suppressed in G(1) and G(2)/M. Smc3 head acetylation and its cell cycle regulation provide important insights into the biology and mechanism of cohesion establishment.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Unal, Elcin -- Heidinger-Pauli, Jill M -- Kim, Woong -- Guacci, Vincent -- Onn, Itay -- Gygi, Steven P -- Koshland, Douglas E -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2008 Jul 25;321(5888):566-9. doi: 10.1126/science.1157880.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Howard Hughes Medical Institute and Department of Embryology, Carnegie Institution, 3520 San Martin Drive, Baltimore, MD 21218, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/18653894" target="_blank"〉PubMed〈/a〉
