    Description: This study describes comprehensive polling of transcription start and termination sites and analysis of previously unidentified full-length complementary DNAs derived from the mouse genome. We identify the 5' and 3' boundaries of 181,047 transcripts with extensive variation in transcripts arising from alternative promoter usage, splicing, and polyadenylation. There are 16,247 new mouse protein-coding transcripts, including 5154 encoding previously unidentified proteins. Genomic mapping of the transcriptome reveals transcriptional forests, with overlapping transcription on both strands, separated by deserts in which few transcripts are observed. The data provide a comprehensive platform for the comparative analysis of mammalian transcriptional regulation in differentiation and development.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Carninci, P -- Kasukawa, T -- Katayama, S -- Gough, J -- Frith, M C -- Maeda, N -- Oyama, R -- Ravasi, T -- Lenhard, B -- Wells, C -- Kodzius, R -- Shimokawa, K -- Bajic, V B -- Brenner, S E -- Batalov, S -- Forrest, A R R -- Zavolan, M -- Davis, M J -- Wilming, L G -- Aidinis, V -- Allen, J E -- Ambesi-Impiombato, A -- Apweiler, R -- Aturaliya, R N -- Bailey, T L -- Bansal, M -- Baxter, L -- Beisel, K W -- Bersano, T -- Bono, H -- Chalk, A M -- Chiu, K P -- Choudhary, V -- Christoffels, A -- Clutterbuck, D R -- Crowe, M L -- Dalla, E -- Dalrymple, B P -- de Bono, B -- Della Gatta, G -- di Bernardo, D -- Down, T -- Engstrom, P -- Fagiolini, M -- Faulkner, G -- Fletcher, C F -- Fukushima, T -- Furuno, M -- Futaki, S -- Gariboldi, M -- Georgii-Hemming, P -- Gingeras, T R -- Gojobori, T -- Green, R E -- Gustincich, S -- Harbers, M -- Hayashi, Y -- Hensch, T K -- Hirokawa, N -- Hill, D -- Huminiecki, L -- Iacono, M -- Ikeo, K -- Iwama, A -- Ishikawa, T -- Jakt, M -- Kanapin, A -- Katoh, M -- Kawasawa, Y -- Kelso, J -- Kitamura, H -- Kitano, H -- Kollias, G -- Krishnan, S P T -- Kruger, A -- Kummerfeld, S K -- Kurochkin, I V -- Lareau, L F -- Lazarevic, D -- Lipovich, L -- Liu, J -- Liuni, S -- McWilliam, S -- Madan Babu, M -- Madera, M -- Marchionni, L -- Matsuda, H -- Matsuzawa, S -- Miki, H -- Mignone, F -- Miyake, S -- Morris, K -- Mottagui-Tabar, S -- Mulder, N -- Nakano, N -- Nakauchi, H -- Ng, P -- Nilsson, R -- Nishiguchi, S -- Nishikawa, S -- Nori, F -- Ohara, O -- Okazaki, Y -- Orlando, V -- Pang, K C -- Pavan, W J -- Pavesi, G -- Pesole, G -- Petrovsky, N -- Piazza, S -- Reed, J -- Reid, J F -- Ring, B Z -- Ringwald, M -- Rost, B -- Ruan, Y -- Salzberg, S L -- Sandelin, A -- Schneider, C -- Schonbach, C -- Sekiguchi, K -- Semple, C A M -- Seno, S -- Sessa, L -- Sheng, Y -- Shibata, Y -- Shimada, H -- Shimada, K -- Silva, D -- Sinclair, B -- Sperling, S -- Stupka, E -- Sugiura, K -- Sultana, R -- Takenaka, Y -- Taki, K -- Tammoja, K -- Tan, S L -- Tang, S -- Taylor, M S -- Tegner, J -- Teichmann, S A -- Ueda, H R -- van Nimwegen, E -- Verardo, R -- Wei, C L -- Yagi, K -- Yamanishi, H -- Zabarovsky, E -- Zhu, S -- Zimmer, A -- Hide, W -- Bult, C -- Grimmond, S M -- Teasdale, R D -- Liu, E T -- Brusic, V -- Quackenbush, J -- Wahlestedt, C -- Mattick, J S -- Hume, D A -- Kai, C -- Sasaki, D -- Tomaru, Y -- Fukuda, S -- Kanamori-Katayama, M -- Suzuki, M -- Aoki, J -- Arakawa, T -- Iida, J -- Imamura, K -- Itoh, M -- Kato, T -- Kawaji, H -- Kawagashira, N -- Kawashima, T -- Kojima, M -- Kondo, S -- Konno, H -- Nakano, K -- Ninomiya, N -- Nishio, T -- Okada, M -- Plessy, C -- Shibata, K -- Shiraki, T -- Suzuki, S -- Tagami, M -- Waki, K -- Watahiki, A -- Okamura-Oho, Y -- Suzuki, H -- Kawai, J -- Hayashizaki, Y -- FANTOM Consortium -- RIKEN Genome Exploration Research Group and Genome Science Group (Genome Network Project Core Group) -- TGM03P17/Telethon/Italy -- TGM06S01/Telethon/Italy -- New York, N.Y. -- Science. 2005 Sep 2;309(5740):1559-63.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16141072" target="_blank"〉PubMed〈/a〉

    Description: In vitro studies have indicated that reactive oxygen species (ROS) and the oxidation of signaling molecules are important mediators of signal transduction. We have identified two pathways by which the altered redox chemistry of the clk-1 mutants of Caenorhabditis elegans acts in vivo on germline development. One pathway depends on the oxidation of an analog of vertebrate low density lipoprotein (LDL) and acts on the germline through the Ack-related tyrosine kinase (ARK-1) kinase and inositol trisphosphate (IP3) signaling. The other pathway is the oncogenic ras signaling pathway, whose action on germline as well as vulval development appears to be modulated by cytoplasmic ROS.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Shibata, Yukimasa -- Branicky, Robyn -- Landaverde, Irene Oviedo -- Hekimi, Siegfried -- New York, N.Y. -- Science. 2003 Dec 5;302(5651):1779-82.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biology, McGill University, 1205 Avenue Docteur Penfield, Montreal, Quebec, Canada, H3A 1B1.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/14657502" target="_blank"〉PubMed〈/a〉

    Description: The tubular structure of the endoplasmic reticulum (ER) appears to be generated by integral membrane proteins, the reticulons and a protein family consisting of DP1 in mammals and Yop1p in yeast. Here, individual members of these families were found to be sufficient to generate membrane tubules. When we purified yeast Yop1p and incorporated it into proteoliposomes, narrow tubules (approximately 15 to 17 nanometers in diameter) were generated. Tubule formation occurred with different lipids; required essentially only the central portion of the protein, including its two long hydrophobic segments; and was prevented by mutations that affected tubule formation in vivo. Tubules were also formed by reconstituted purified yeast Rtn1p. Tubules made in vitro were narrower than normal ER tubules, due to a higher concentration of tubule-inducing proteins. The shape and oligomerization of the "morphogenic" proteins could explain the formation of the tubular ER.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hu, Junjie -- Shibata, Yoko -- Voss, Christiane -- Shemesh, Tom -- Li, Zongli -- Coughlin, Margaret -- Kozlov, Michael M -- Rapoport, Tom A -- Prinz, William A -- Howard Hughes Medical Institute/ -- Intramural NIH HHS/ -- New York, N.Y. -- Science. 2008 Feb 29;319(5867):1247-50. doi: 10.1126/science.1153634.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Howard Hughes Medical Institute and Department of Cell Biology, Harvard Medical School, 240 Longwood Avenue, Boston, MA 02115, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/18309084" target="_blank"〉PubMed〈/a〉

    Description: Nuclear export of microRNAs (miRNAs) by exportin-5 (Exp-5) is an essential step in miRNA biogenesis. Here, we present the 2.9 angstrom structure of the pre-miRNA nuclear export machinery formed by pre-miRNA complexed with Exp-5 and a guanine triphosphate (GTP)-bound form of the small nuclear guanine triphosphatase (GTPase) Ran (RanGTP). The x-ray structure shows that Exp-5:RanGTP recognizes the 2-nucleotide 3' overhang structure and the double-stranded stem of the pre-miRNA. Exp-5:RanGTP shields the pre-miRNA stem from degradation in a baseball mitt-like structure where it is held by broadly distributed weak interactions, whereas a tunnel-like structure of Exp-5 interacts strongly with the 2-nucleotide 3' overhang through hydrogen bonds and ionic interactions. RNA recognition by Exp-5:RanGTP does not depend on RNA sequence, implying that Exp-5:RanGTP can recognize a variety of pre-miRNAs.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Okada, Chimari -- Yamashita, Eiki -- Lee, Soo Jae -- Shibata, Satoshi -- Katahira, Jun -- Nakagawa, Atsushi -- Yoneda, Yoshihiro -- Tsukihara, Tomitake -- New York, N.Y. -- Science. 2009 Nov 27;326(5957):1275-9. doi: 10.1126/science.1178705.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Institute for Protein Research, Osaka University, 3-2 Yamada-oka, Suita, Osaka 565-0871, Japan.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19965479" target="_blank"〉PubMed〈/a〉
