    Whole-genome shotgun assembly and analysis of the genome of Fugu rubripes (2002)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2002-07-27
    Description: The compact genome of Fugu rubripes has been sequenced to over 95% coverage, and more than 80% of the assembly is in multigene-sized scaffolds. In this 365-megabase vertebrate genome, repetitive DNA accounts for less than one-sixth of the sequence, and gene loci occupy about one-third of the genome. As with the human genome, gene loci are not evenly distributed, but are clustered into sparse and dense regions. Some "giant" genes were observed that had average coding sequence sizes but were spread over genomic lengths significantly larger than those of their human orthologs. Although three-quarters of predicted human proteins have a strong match to Fugu, approximately a quarter of the human proteins had highly diverged from or had no pufferfish homologs, highlighting the extent of protein evolution in the 450 million years since teleosts and mammals diverged. Conserved linkages between Fugu and human genes indicate the preservation of chromosomal segments from the common vertebrate ancestor, but with considerable scrambling of gene order.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Aparicio, Samuel -- Chapman, Jarrod -- Stupka, Elia -- Putnam, Nik -- Chia, Jer-Ming -- Dehal, Paramvir -- Christoffels, Alan -- Rash, Sam -- Hoon, Shawn -- Smit, Arian -- Gelpke, Maarten D Sollewijn -- Roach, Jared -- Oh, Tania -- Ho, Isaac Y -- Wong, Marie -- Detter, Chris -- Verhoef, Frans -- Predki, Paul -- Tay, Alice -- Lucas, Susan -- Richardson, Paul -- Smith, Sarah F -- Clark, Melody S -- Edwards, Yvonne J K -- Doggett, Norman -- Zharkikh, Andrey -- Tavtigian, Sean V -- Pruss, Dmitry -- Barnstead, Mary -- Evans, Cheryl -- Baden, Holly -- Powell, Justin -- Glusman, Gustavo -- Rowen, Lee -- Hood, Leroy -- Tan, Y H -- Elgar, Greg -- Hawkins, Trevor -- Venkatesh, Byrappa -- Rokhsar, Daniel -- Brenner, Sydney -- New York, N.Y. -- Science. 2002 Aug 23;297(5585):1301-10.

    An asymmetric model for the nucleosome: a binding site for linker histones inside the DNA gyres (1996)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1996-10-25
    Description: Histone-DNA contacts within a nucleosome influence the function of trans-acting factors and the molecular machines required to activate the transcription process. The internal architecture of a positioned nucleosome has now been probed with the use of photoactivatable cross-linking reagents to determine the placement of histones along the DNA molecule. A model for the nucleosome is proposed in which the winged-helix domain of the linker histone is asymmetrically located inside the gyres of DNA that also wrap around the core histones. This domain extends the path of the protein superhelix to one side of the core particle.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Pruss, D -- Bartholomew, B -- Persinger, J -- Hayes, J -- Arents, G -- Moudrianakis, E N -- Wolffe, A P -- New York, N.Y. -- Science. 1996 Oct 25;274(5287):614-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉National Institute of Child Health and Human Development, National Institutes of Health, Bethesda, MD 20892-2710, USA. awlme@helix.nih.gov〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8849453" target="_blank"〉PubMed〈/a〉
