    Description: Mutations in the BRCA2 (breast cancer susceptibility gene 2) tumor suppressor lead to chromosomal instability due to defects in the repair of double-strand DNA breaks (DSBs) by homologous recombination, but BRCA2's role in this process has been unclear. Here, we present the 3.1 angstrom crystal structure of a approximately 90-kilodalton BRCA2 domain bound to DSS1, which reveals three oligonucleotide-binding (OB) folds and a helix-turn-helix (HTH) motif. We also (i) demonstrate that this BRCA2 domain binds single-stranded DNA, (ii) present its 3.5 angstrom structure bound to oligo(dT)9, (iii) provide data that implicate the HTH motif in dsDNA binding, and (iv) show that BRCA2 stimulates RAD51-mediated recombination in vitro. These findings establish that BRCA2 functions directly in homologous recombination and provide a structural and biochemical basis for understanding the loss of recombination-mediated DSB repair in BRCA2-associated cancers.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Yang, Haijuan -- Jeffrey, Philip D -- Miller, Julie -- Kinnucan, Elspeth -- Sun, Yutong -- Thoma, Nicolas H -- Zheng, Ning -- Chen, Phang-Lang -- Lee, Wen-Hwa -- Pavletich, Nikola P -- New York, N.Y. -- Science. 2002 Sep 13;297(5588):1837-48.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Pharmacology, Sloan-Kettering Division, Joan and Sanford I.

    Description: We report on the quality of a whole-genome assembly of Drosophila melanogaster and the nature of the computer algorithms that accomplished it. Three independent external data sources essentially agree with and support the assembly's sequence and ordering of contigs across the euchromatic portion of the genome. In addition, there are isolated contigs that we believe represent nonrepetitive pockets within the heterochromatin of the centromeres. Comparison with a previously sequenced 2.9- megabase region indicates that sequencing accuracy within nonrepetitive segments is greater than 99. 99% without manual curation. As such, this initial reconstruction of the Drosophila sequence should be of substantial value to the scientific community.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Myers, E W -- Sutton, G G -- Delcher, A L -- Dew, I M -- Fasulo, D P -- Flanigan, M J -- Kravitz, S A -- Mobarry, C M -- Reinert, K H -- Remington, K A -- Anson, E L -- Bolanos, R A -- Chou, H H -- Jordan, C M -- Halpern, A L -- Lonardi, S -- Beasley, E M -- Brandon, R C -- Chen, L -- Dunn, P J -- Lai, Z -- Liang, Y -- Nusskern, D R -- Zhan, M -- Zhang, Q -- Zheng, X -- Rubin, G M -- Adams, M D -- Venter, J C -- New York, N.Y. -- Science. 2000 Mar 24;287(5461):2196-204.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Celera Genomics, Inc., 45 West Gude Drive, Rockville, MD 20850, USA.

    Description: The high degree of similarity between the mouse and human genomes is demonstrated through analysis of the sequence of mouse chromosome 16 (Mmu 16), which was obtained as part of a whole-genome shotgun assembly of the mouse genome. The mouse genome is about 10% smaller than the human genome, owing to a lower repetitive DNA content. Comparison of the structure and protein-coding potential of Mmu 16 with that of the homologous segments of the human genome identifies regions of conserved synteny with human chromosomes (Hsa) 3, 8, 12, 16, 21, and 22. Gene content and order are highly conserved between Mmu 16 and the syntenic blocks of the human genome. Of the 731 predicted genes on Mmu 16, 509 align with orthologs on the corresponding portions of the human genome, 44 are likely paralogous to these genes, and 164 genes have homologs elsewhere in the human genome; there are 14 genes for which we could find no human counterpart.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Mural, Richard J -- Adams, Mark D -- Myers, Eugene W -- Smith, Hamilton O -- Miklos, George L Gabor -- Wides, Ron -- Halpern, Aaron -- Li, Peter W -- Sutton, Granger G -- Nadeau, Joe -- Salzberg, Steven L -- Holt, Robert A -- Kodira, Chinnappa D -- Lu, Fu -- Chen, Lin -- Deng, Zuoming -- Evangelista, Carlos C -- Gan, Weiniu -- Heiman, Thomas J -- Li, Jiayin -- Li, Zhenya -- Merkulov, Gennady V -- Milshina, Natalia V -- Naik, Ashwinikumar K -- Qi, Rong -- Shue, Bixiong Chris -- Wang, Aihui -- Wang, Jian -- Wang, Xin -- Yan, Xianghe -- Ye, Jane -- Yooseph, Shibu -- Zhao, Qi -- Zheng, Liansheng -- Zhu, Shiaoping C -- Biddick, Kendra -- Bolanos, Randall -- Delcher, Arthur L -- Dew, Ian M -- Fasulo, Daniel -- Flanigan, Michael J -- Huson, Daniel H -- Kravitz, Saul A -- Miller, Jason R -- Mobarry, Clark M -- Reinert, Knut -- Remington, Karin A -- Zhang, Qing -- Zheng, Xiangqun H -- Nusskern, Deborah R -- Lai, Zhongwu -- Lei, Yiding -- Zhong, Wenyan -- Yao, Alison -- Guan, Ping -- Ji, Rui-Ru -- Gu, Zhiping -- Wang, Zhen-Yuan -- Zhong, Fei -- Xiao, Chunlin -- Chiang, Chia-Chien -- Yandell, Mark -- Wortman, Jennifer R -- Amanatides, Peter G -- Hladun, Suzanne L -- Pratts, Eric C -- Johnson, Jeffery E -- Dodson, Kristina L -- Woodford, Kerry J -- Evans, Cheryl A -- Gropman, Barry -- Rusch, Douglas B -- Venter, Eli -- Wang, Mei -- Smith, Thomas J -- Houck, Jarrett T -- Tompkins, Donald E -- Haynes, Charles -- Jacob, Debbie -- Chin, Soo H -- Allen, David R -- Dahlke, Carl E -- Sanders, Robert -- Li, Kelvin -- Liu, Xiangjun -- Levitsky, Alexander A -- Majoros, William H -- Chen, Quan -- Xia, Ashley C -- Lopez, John R -- Donnelly, Michael T -- Newman, Matthew H -- Glodek, Anna -- Kraft, Cheryl L -- Nodell, Marc -- Ali, Feroze -- An, Hui-Jin -- Baldwin-Pitts, Danita -- Beeson, Karen Y -- Cai, Shuang -- Carnes, Mark -- Carver, Amy -- Caulk, Parris M -- Center, Angela -- Chen, Yen-Hui -- Cheng, Ming-Lai -- Coyne, My D -- Crowder, Michelle -- Danaher, Steven -- Davenport, Lionel B -- Desilets, Raymond -- Dietz, Susanne M -- Doup, Lisa -- Dullaghan, Patrick -- Ferriera, Steven -- Fosler, Carl R -- Gire, Harold C -- Gluecksmann, Andres -- Gocayne, Jeannine D -- Gray, Jonathan -- Hart, Brit -- Haynes, Jason -- Hoover, Jeffery -- Howland, Tim -- Ibegwam, Chinyere -- Jalali, Mena -- Johns, David -- Kline, Leslie -- Ma, Daniel S -- MacCawley, Steven -- Magoon, Anand -- Mann, Felecia -- May, David -- McIntosh, Tina C -- Mehta, Somil -- Moy, Linda -- Moy, Mee C -- Murphy, Brian J -- Murphy, Sean D -- Nelson, Keith A -- Nuri, Zubeda -- Parker, Kimberly A -- Prudhomme, Alexandre C -- Puri, Vinita N -- Qureshi, Hina -- Raley, John C -- Reardon, Matthew S -- Regier, Megan A -- Rogers, Yu-Hui C -- Romblad, Deanna L -- Schutz, Jakob -- Scott, John L -- Scott, Richard -- Sitter, Cynthia D -- Smallwood, Michella -- Sprague, Arlan C -- Stewart, Erin -- Strong, Renee V -- Suh, Ellen -- Sylvester, Karena -- Thomas, Reginald -- Tint, Ni Ni -- Tsonis, Christopher -- Wang, Gary -- Wang, George -- Williams, Monica S -- Williams, Sherita M -- Windsor, Sandra M -- Wolfe, Keriellen -- Wu, Mitchell M -- Zaveri, Jayshree -- Chaturvedi, Kabir -- Gabrielian, Andrei E -- Ke, Zhaoxi -- Sun, Jingtao -- Subramanian, Gangadharan -- Venter, J Craig -- Pfannkoch, Cynthia M -- Barnstead, Mary -- Stephenson, Lisa D -- New York, N.Y. -- Science. 2002 May 31;296(5573):1661-71.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Celera Genomics, 45 West Gude Drive, Rockville, MD 20850, USA. richard.mural@celera.com〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/12040188" target="_blank"〉PubMed〈/a〉

    Description: The 5.67-megabase genome of the plant pathogen Agrobacterium tumefaciens C58 consists of a circular chromosome, a linear chromosome, and two plasmids. Extensive orthology and nucleotide colinearity between the genomes of A. tumefaciens and the plant symbiont Sinorhizobium meliloti suggest a recent evolutionary divergence. Their similarities include metabolic, transport, and regulatory systems that promote survival in the highly competitive rhizosphere; differences are apparent in their genome structure and virulence gene complement. Availability of the A. tumefaciens sequence will facilitate investigations into the molecular basis of pathogenesis and the evolutionary divergence of pathogenic and symbiotic lifestyles.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Wood, D W -- Setubal, J C -- Kaul, R -- Monks, D E -- Kitajima, J P -- Okura, V K -- Zhou, Y -- Chen, L -- Wood, G E -- Almeida, N F Jr -- Woo, L -- Chen, Y -- Paulsen, I T -- Eisen, J A -- Karp, P D -- Bovee, D Sr -- Chapman, P -- Clendenning, J -- Deatherage, G -- Gillet, W -- Grant, C -- Kutyavin, T -- Levy, R -- Li, M J -- McClelland, E -- Palmieri, A -- Raymond, C -- Rouse, G -- Saenphimmachak, C -- Wu, Z -- Romero, P -- Gordon, D -- Zhang, S -- Yoo, H -- Tao, Y -- Biddle, P -- Jung, M -- Krespan, W -- Perry, M -- Gordon-Kamm, B -- Liao, L -- Kim, S -- Hendrick, C -- Zhao, Z Y -- Dolan, M -- Chumley, F -- Tingey, S V -- Tomb, J F -- Gordon, M P -- Olson, M V -- Nester, E W -- GM19642/GM/NIGMS NIH HHS/ -- GM32618/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2001 Dec 14;294(5550):2317-23.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Microbiology, University of Washington, 1959 NE Pacific Street, Box 357242, Seattle, WA 98195, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/11743193" target="_blank"〉PubMed〈/a〉

    Description: The AMP-activated protein kinase (AMPK) is characterized by its ability to bind to AMP, which enables it to adjust enzymatic activity by sensing the cellular energy status and maintain the balance between ATP production and consumption in eukaryotic cells. It also has important roles in the regulation of cell growth and proliferation, and in the establishment and maintenance of cell polarity. These important functions have rendered AMPK an important drug target for obesity, type 2 diabetes and cancer treatments. However, the regulatory mechanism of AMPK activity by AMP binding remains unsolved. Here we report the crystal structures of an unphosphorylated fragment of the AMPK alpha-subunit (KD-AID) from Schizosaccharomyces pombe that contains both the catalytic kinase domain and an autoinhibitory domain (AID), and of a phosphorylated kinase domain from Saccharomyces cerevisiae (Snf1-pKD). The AID binds, from the 'backside', to the hinge region of its kinase domain, forming contacts with both amino-terminal and carboxy-terminal lobes. Structural analyses indicate that AID binding might constrain the mobility of helix alphaC, hence resulting in an autoinhibited KD-AID with much lower kinase activity than that of the kinase domain alone. AMP activates AMPK both allosterically and by inhibiting dephosphorylation. Further in vitro kinetic studies demonstrate that disruption of the KD-AID interface reverses the autoinhibition and these AMPK heterotrimeric mutants no longer respond to the change in AMP concentration. The structural and biochemical data have shown the primary mechanism of AMPK autoinhibition and suggest a conformational switch model for AMPK activation by AMP.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Chen, Lei -- Jiao, Zhi-Hao -- Zheng, Li-Sha -- Zhang, Yuan-Yuan -- Xie, Shu-Tao -- Wang, Zhi-Xin -- Wu, Jia-Wei -- England -- Nature. 2009 Jun 25;459(7250):1146-9. doi: 10.1038/nature08075.

    Description: The myoD family of DNA binding proteins has been implicated in the control of myogenesis in a variety of organisms. Searches for homologs in the nematode Caenorhabditis elegans yielded only one gene, designated hlh-1, expressed in body-wall muscle cells and their precursors. To assess the role of hlh-1 in C. elegans myogenesis, genetic deficiencies spanning the hlh-1 locus were isolated after gamma irradiation. Embryos homozygous for these deficiencies exhibited extensive body-wall muscle differentiation, including expression of several characteristic myofilament proteins and weak contracile behavior. Thus, zygotic hlh-1 expression was not required for body-wall muscle precursors to adopt muscle cell fates.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Chen, L -- Krause, M -- Draper, B -- Weintraub, H -- Fire, A -- R01 GM037706/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1992 Apr 10;256(5054):240-3.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Carnegie Institution of Washington, Baltimore, MD 21210.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/1314423" target="_blank"〉PubMed〈/a〉

    Description: Mutations of the gene encoding p53, a 53-kilodalton cellular protein, are found frequently in human tumor cells, suggesting a crucial role for this gene in human oncogenesis. To model the stepwise mutation or loss of both p53 alleles during tumorigenesis, a human osteosarcoma cell line, Saos-2, was used that completely lacked endogenous p53. Single copies of exogenous p53 genes were then introduced by infecting cells with recombinant retroviruses containing either point-mutated or wild-type versions of the p53 cDNA sequence. Expression of wild-type p53 suppressed the neoplastic phenotype of Saos-2 cells, whereas expression of mutated p53 conferred a limited growth advantage to cells in the absence of wild-type p53. Wild-type p53 was phenotypically dominant to mutated p53 in a two-allele configuration. These results suggest that, as with the retinoblastoma gene, mutation of both alleles of the p53 gene is essential for its role in oncogenesis.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Chen, P L -- Chen, Y M -- Bookstein, R -- Lee, W H -- CA51495/CA/NCI NIH HHS/ -- EY00278/EY/NEI NIH HHS/ -- EY05758/EY/NEI NIH HHS/ -- New York, N.Y. -- Science. 1990 Dec 14;250(4987):1576-80.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Pathology, School of Medicine, University of California, San Diego, La Jolla 92093-0612.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2274789" target="_blank"〉PubMed〈/a〉

    Description: Introduction of a normal retinoblastoma gene (RB) into retinoblastoma cells was previously shown to suppress several aspects of their neoplastic phenotype, including tumorigenicity in nude mice, thereby directly demonstrating a cancer suppression function of RB. To explore the possibility of a similar activity in a common adult tumor, RB expression was examined in three human prostate carcinoma cell lines. One of these, DU145, contained an abnormally small protein translated from an RB messenger RNA transcript that lacked 105 nucleotides encoded by exon 21. To assess the functional consequences of this mutation, normal RB expression was restored in DU145 cells by retrovirus-mediated gene transfer. Cells that maintained stable exogenous RB expression lost their ability to form tumors in nude mice, although their growth rate in culture was apparently unaltered. These results suggest that RB inactivation can play a significant role in the genesis of a common adult neoplasm and that restoration of normal RB-encoded protein in tumors could have clinical utility.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Bookstein, R -- Shew, J Y -- Chen, P L -- Scully, P -- Lee, W H -- 5758/PHS HHS/ -- New York, N.Y. -- Science. 1990 Feb 9;247(4943):712-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Pathology, School of Medicine, University of California, San Diego, La Jolla 92093.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2300823" target="_blank"〉PubMed〈/a〉

    Description: Chlamydomonas reinhardtii is a unicellular green alga whose lineage diverged from land plants over 1 billion years ago. It is a model system for studying chloroplast-based photosynthesis, as well as the structure, assembly, and function of eukaryotic flagella (cilia), which were inherited from the common ancestor of plants and animals, but lost in land plants. We sequenced the approximately 120-megabase nuclear genome of Chlamydomonas and performed comparative phylogenomic analyses, identifying genes encoding uncharacterized proteins that are likely associated with the function and biogenesis of chloroplasts or eukaryotic flagella. Analyses of the Chlamydomonas genome advance our understanding of the ancestral eukaryotic cell, reveal previously unknown genes associated with photosynthetic and flagellar functions, and establish links between ciliopathy and the composition and function of flagella.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2875087/" 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/PMC2875087/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Merchant, Sabeeha S -- Prochnik, Simon E -- Vallon, Olivier -- Harris, Elizabeth H -- Karpowicz, Steven J -- Witman, George B -- Terry, Astrid -- Salamov, Asaf -- Fritz-Laylin, Lillian K -- Marechal-Drouard, Laurence -- Marshall, Wallace F -- Qu, Liang-Hu -- Nelson, David R -- Sanderfoot, Anton A -- Spalding, Martin H -- Kapitonov, Vladimir V -- Ren, Qinghu -- Ferris, Patrick -- Lindquist, Erika -- Shapiro, Harris -- Lucas, Susan M -- Grimwood, Jane -- Schmutz, Jeremy -- Cardol, Pierre -- Cerutti, Heriberto -- Chanfreau, Guillaume -- Chen, Chun-Long -- Cognat, Valerie -- Croft, Martin T -- Dent, Rachel -- Dutcher, Susan -- Fernandez, Emilio -- Fukuzawa, Hideya -- Gonzalez-Ballester, David -- Gonzalez-Halphen, Diego -- Hallmann, Armin -- Hanikenne, Marc -- Hippler, Michael -- Inwood, William -- Jabbari, Kamel -- Kalanon, Ming -- Kuras, Richard -- Lefebvre, Paul A -- Lemaire, Stephane D -- Lobanov, Alexey V -- Lohr, Martin -- Manuell, Andrea -- Meier, Iris -- Mets, Laurens -- Mittag, Maria -- Mittelmeier, Telsa -- Moroney, James V -- Moseley, Jeffrey -- Napoli, Carolyn -- Nedelcu, Aurora M -- Niyogi, Krishna -- Novoselov, Sergey V -- Paulsen, Ian T -- Pazour, Greg -- Purton, Saul -- Ral, Jean-Philippe -- Riano-Pachon, Diego Mauricio -- Riekhof, Wayne -- Rymarquis, Linda -- Schroda, Michael -- Stern, David -- Umen, James -- Willows, Robert -- Wilson, Nedra -- Zimmer, Sara Lana -- Allmer, Jens -- Balk, Janneke -- Bisova, Katerina -- Chen, Chong-Jian -- Elias, Marek -- Gendler, Karla -- Hauser, Charles -- Lamb, Mary Rose -- Ledford, Heidi -- Long, Joanne C -- Minagawa, Jun -- Page, M Dudley -- Pan, Junmin -- Pootakham, Wirulda -- Roje, Sanja -- Rose, Annkatrin -- Stahlberg, Eric -- Terauchi, Aimee M -- Yang, Pinfen -- Ball, Steven -- Bowler, Chris -- Dieckmann, Carol L -- Gladyshev, Vadim N -- Green, Pamela -- Jorgensen, Richard -- Mayfield, Stephen -- Mueller-Roeber, Bernd -- Rajamani, Sathish -- Sayre, Richard T -- Brokstein, Peter -- Dubchak, Inna -- Goodstein, David -- Hornick, Leila -- Huang, Y Wayne -- Jhaveri, Jinal -- Luo, Yigong -- Martinez, Diego -- Ngau, Wing Chi Abby -- Otillar, Bobby -- Poliakov, Alexander -- Porter, Aaron -- Szajkowski, Lukasz -- Werner, Gregory -- Zhou, Kemin -- Grigoriev, Igor V -- Rokhsar, Daniel S -- Grossman, Arthur R -- GM07185/GM/NIGMS NIH HHS/ -- GM42143/GM/NIGMS NIH HHS/ -- R01 GM032843/GM/NIGMS NIH HHS/ -- R01 GM042143/GM/NIGMS NIH HHS/ -- R01 GM042143-09/GM/NIGMS NIH HHS/ -- R01 GM060992/GM/NIGMS NIH HHS/ -- R01 GM062915-06/GM/NIGMS NIH HHS/ -- R37 GM030626/GM/NIGMS NIH HHS/ -- R37 GM042143/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2007 Oct 12;318(5848):245-50.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Chemistry and Biochemistry, University of California at Los Angeles, Los Angeles, CA 90095, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17932292" target="_blank"〉PubMed〈/a〉

    Description: The manipulation of protein backbone structure to control interaction and function is a challenge for protein engineering. We integrated computational design with experimental selection for grafting the backbone and side chains of a two-segment HIV gp120 epitope, targeted by the cross-neutralizing antibody b12, onto an unrelated scaffold protein. The final scaffolds bound b12 with high specificity and with affinity similar to that of gp120, and crystallographic analysis of a scaffold bound to b12 revealed high structural mimicry of the gp120-b12 complex structure. The method can be generalized to design other functional proteins through backbone grafting.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Azoitei, Mihai L -- Correia, Bruno E -- Ban, Yih-En Andrew -- Carrico, Chris -- Kalyuzhniy, Oleksandr -- Chen, Lei -- Schroeter, Alexandria -- Huang, Po-Ssu -- McLellan, Jason S -- Kwong, Peter D -- Baker, David -- Strong, Roland K -- Schief, William R -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2011 Oct 21;334(6054):373-6. doi: 10.1126/science.1209368.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biochemistry, University of Washington, Seattle, WA 98195, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/22021856" target="_blank"〉PubMed〈/a〉
