Description: Recombination, together with mutation, gives rise to genetic variation in populations. Here we leverage the recent mixture of people of African and European ancestry in the Americas to build a genetic map measuring the probability of crossing over at each position in the genome, based on about 2.1 million crossovers in 30,000 unrelated African Americans. At intervals of more than three megabases it is nearly identical to a map built in Europeans. At finer scales it differs significantly, and we identify about 2,500 recombination hotspots that are active in people of West African ancestry but nearly inactive in Europeans. The probability of a crossover at these hotspots is almost fully controlled by the alleles an individual carries at PRDM9 (P value 〈 10(-245)). We identify a 17-base-pair DNA sequence motif that is enriched in these hotspots, and is an excellent match to the predicted binding target of PRDM9 alleles common in West Africans and rare in Europeans. Sites of this motif are predicted to be risk loci for disease-causing genomic rearrangements in individuals carrying these alleles. More generally, this map provides a resource for research in human genetic variation and evolution.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3154982/" 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/PMC3154982/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hinch, Anjali G -- Tandon, Arti -- Patterson, Nick -- Song, Yunli -- Rohland, Nadin -- Palmer, Cameron D -- Chen, Gary K -- Wang, Kai -- Buxbaum, Sarah G -- Akylbekova, Ermeg L -- Aldrich, Melinda C -- Ambrosone, Christine B -- Amos, Christopher -- Bandera, Elisa V -- Berndt, Sonja I -- Bernstein, Leslie -- Blot, William J -- Bock, Cathryn H -- Boerwinkle, Eric -- Cai, Qiuyin -- Caporaso, Neil -- Casey, Graham -- Cupples, L Adrienne -- Deming, Sandra L -- Diver, W Ryan -- Divers, Jasmin -- Fornage, Myriam -- Gillanders, Elizabeth M -- Glessner, Joseph -- Harris, Curtis C -- Hu, Jennifer J -- Ingles, Sue A -- Isaacs, William -- John, Esther M -- Kao, W H Linda -- Keating, Brendan -- Kittles, Rick A -- Kolonel, Laurence N -- Larkin, Emma -- Le Marchand, Loic -- McNeill, Lorna H -- Millikan, Robert C -- Murphy, Adam -- Musani, Solomon -- Neslund-Dudas, Christine -- Nyante, Sarah -- Papanicolaou, George J -- Press, Michael F -- Psaty, Bruce M -- Reiner, Alex P -- Rich, Stephen S -- Rodriguez-Gil, Jorge L -- Rotter, Jerome I -- Rybicki, Benjamin A -- Schwartz, Ann G -- Signorello, Lisa B -- Spitz, Margaret -- Strom, Sara S -- Thun, Michael J -- Tucker, Margaret A -- Wang, Zhaoming -- Wiencke, John K -- Witte, John S -- Wrensch, Margaret -- Wu, Xifeng -- Yamamura, Yuko -- Zanetti, Krista A -- Zheng, Wei -- Ziegler, Regina G -- Zhu, Xiaofeng -- Redline, Susan -- Hirschhorn, Joel N -- Henderson, Brian E -- Taylor, Herman A Jr -- Price, Alkes L -- Hakonarson, Hakon -- Chanock, Stephen J -- Haiman, Christopher A -- Wilson, James G -- Reich, David -- Myers, Simon R -- 090532/Wellcome Trust/United Kingdom -- CA060691/CA/NCI NIH HHS/ -- CA092447/CA/NCI NIH HHS/ -- CA100374/CA/NCI NIH HHS/ -- CA100598/CA/NCI NIH HHS/ -- CA1116460/CA/NCI NIH HHS/ -- CA1116460S1/CA/NCI NIH HHS/ -- CA121197/CA/NCI NIH HHS/ -- CA121197S2/CA/NCI NIH HHS/ -- CA127219/CA/NCI NIH HHS/ -- CA1326792/CA/NCI NIH HHS/ -- CA140388/CA/NCI NIH HHS/ -- CA141716/CA/NCI NIH HHS/ -- CA148085/CA/NCI NIH HHS/ -- CA148127/CA/NCI NIH HHS/ -- CA22453/CA/NCI NIH HHS/ -- CA54281/CA/NCI NIH HHS/ -- CA55769/CA/NCI NIH HHS/ -- CA58223/CA/NCI NIH HHS/ -- CA63464/CA/NCI NIH HHS/ -- CA68485/CA/NCI NIH HHS/ -- CA68578/CA/NCI NIH HHS/ -- CA77305/CA/NCI NIH HHS/ -- CA87895/CA/NCI NIH HHS/ -- CA88164/CA/NCI NIH HHS/ -- ES007784/ES/NIEHS NIH HHS/ -- ES011126/ES/NIEHS NIH HHS/ -- ES06717/ES/NIEHS NIH HHS/ -- ES10126/ES/NIEHS NIH HHS/ -- GM08016/GM/NIGMS NIH HHS/ -- GM091332/GM/NIGMS NIH HHS/ -- HD33175/HD/NICHD NIH HHS/ -- HG004726/HG/NHGRI NIH HHS/ -- HHSN268200960009C/PHS HHS/ -- HL084107/HL/NHLBI NIH HHS/ -- N01-HC-65226/HC/NHLBI NIH HHS/ -- P30 ES010126/ES/NIEHS NIH HHS/ -- R01 CA052689/CA/NCI NIH HHS/ -- R01 CA092447/CA/NCI NIH HHS/ -- R01 HG006399/HG/NHGRI NIH HHS/ -- R01 HL084107-04/HL/NHLBI NIH HHS/ -- R01-CA73629/CA/NCI NIH HHS/ -- U01 HG004168/HG/NHGRI NIH HHS/ -- U01 HG004168-03/HG/NHGRI NIH HHS/ -- Intramural NIH HHS/ -- Wellcome Trust/United Kingdom -- England -- Nature. 2011 Jul 20;476(7359):170-5. doi: 10.1038/nature10336.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Wellcome Trust Centre for Human Genetics, Oxford University, Roosevelt Drive, Oxford OX3 7BN, UK.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/21775986" target="_blank"〉PubMed〈/a〉

Description: To understand the biology and evolution of ruminants, the cattle genome was sequenced to about sevenfold coverage. The cattle genome contains a minimum of 22,000 genes, with a core set of 14,345 orthologs shared among seven mammalian species of which 1217 are absent or undetected in noneutherian (marsupial or monotreme) genomes. Cattle-specific evolutionary breakpoint regions in chromosomes have a higher density of segmental duplications, enrichment of repetitive elements, and species-specific variations in genes associated with lactation and immune responsiveness. Genes involved in metabolism are generally highly conserved, although five metabolic genes are deleted or extensively diverged from their human orthologs. The cattle genome sequence thus provides a resource for understanding mammalian evolution and accelerating livestock genetic improvement for milk and meat production.〈br /〉〈br /〉〈a

Description: Ubiquitination of receptor protein-tyrosine kinases (RPTKs) terminates signaling by marking active receptors for degradation. c-Cbl, an adapter protein for RPTKs, positively regulates RPTK ubiquitination in a manner dependent on its variant SRC homology 2 (SH2) and RING finger domains. Ubiquitin-protein ligases (or E3s) are the components of ubiquitination pathways that recognize target substrates and promote their ligation to ubiquitin. The c-Cbl protein acted as an E3 that can recognize tyrosine-phosphorylated substrates, such as the activated platelet-derived growth factor receptor, through its SH2 domain and that recruits and allosterically activates an E2 ubiquitin-conjugating enzyme through its RING domain. These results reveal an SH2-containing protein that functions as a ubiquitin-protein ligase and thus provide a distinct mechanism for substrate targeting in the ubiquitin system.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Joazeiro, C A -- Wing, S S -- Huang, H -- Leverson, J D -- Hunter, T -- Liu, Y C -- CA39780/CA/NCI NIH HHS/ -- R01 DK56558/DK/NIDDK NIH HHS/ -- T32CA09523/CA/NCI NIH HHS/ -- etc. -- New York, N.Y. -- Science. 1999 Oct 8;286(5438):309-12.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉The Salk Institute, Molecular Biology and Virology Laboratory, La Jolla, CA 92037, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/10514377" target="_blank"〉PubMed〈/a〉

Description: The circadian oscillator of the cyanobacterium Synechococcus elongatus, like those in eukaryotes, is entrained by environmental cues. Inactivation of the gene cikA (circadian input kinase) shortens the circadian period of gene expression rhythms in S. elongatus by approximately 2 hours, changes the phasing of a subset of rhythms, and nearly abolishes resetting of phase by a pulse of darkness. The CikA protein sequence reveals that it is a divergent bacteriophytochrome with characteristic histidine protein kinase motifs and a cryptic response regulator motif. CikA is likely a key component of a pathway that provides environmental input to the circadian oscillator in S. elongatus.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Schmitz, O -- Katayama, M -- Williams, S B -- Kondo, T -- Golden, S S -- GM37040/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2000 Aug 4;289(5480):765-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biology, Texas A&M University, College Station, TX 77843-3258, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/10926536" target="_blank"〉PubMed〈/a〉

Description: The majority (〉99%) of microorganisms from the environment resist cultivation in the laboratory. Ribosomal RNA analysis suggests that uncultivated organisms are found in nearly every prokaryotic group, and several divisions have no known cultivable representatives. We designed a diffusion chamber that allowed the growth of previously uncultivated microorganisms in a simulated natural environment. Colonies of representative marine organisms were isolated in pure culture. These isolates did not grow on artificial media alone but formed colonies in the presence of other microorganisms. This observation may help explain the nature of microbial uncultivability.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kaeberlein, T -- Lewis, K -- Epstein, S S -- New York, N.Y. -- Science. 2002 May 10;296(5570):1127-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Biology Department, Northeastern University, Boston, MA 02115, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/12004133" target="_blank"〉PubMed〈/a〉

Description: Motilin is a 22-amino acid peptide hormone expressed throughout the gastrointestinal (GI) tract of humans and other species. It affects gastric motility by stimulating interdigestive antrum and duodenal contractions. A heterotrimeric guanosine triphosphate-binding protein (G protein)-coupled receptor for motilin was isolated from human stomach, and its amino acid sequence was found to be 52 percent identical to the human receptor for growth hormone secretagogues. The macrolide antibiotic erythromycin also interacted with the cloned motilin receptor, providing a molecular basis for its effects on the human GI tract. The motilin receptor is expressed in enteric neurons of the human duodenum and colon. Development of motilin receptor agonists and antagonists may be useful in the treatment of multiple disorders of GI motility.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Feighner, S D -- Tan, C P -- McKee, K K -- Palyha, O C -- Hreniuk, D L -- Pong, S S -- Austin, C P -- Figueroa, D -- MacNeil, D -- Cascieri, M A -- Nargund, R -- Bakshi, R -- Abramovitz, M -- Stocco, R -- Kargman, S -- O'Neill, G -- Van Der Ploeg, L H -- Evans, J -- Patchett, A A -- Smith, R G -- Howard, A D -- New York, N.Y. -- Science. 1999 Jun 25;284(5423):2184-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Metabolic Disorders, Department of Medicinal Chemistry, Merck Research Laboratories, Building RY-80Y-265, 126 East Lincoln Avenue, Rahway, NJ 07065, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/10381885" target="_blank"〉PubMed〈/a〉

Description: The p160 family of coactivators, SRC-1, GRIP1/TIF2, and p/CIP, mediate transcriptional activation by nuclear hormone receptors. Coactivator-associated arginine methyltransferase 1 (CARM1), a previously unidentified protein that binds to the carboxyl-terminal region of p160 coactivators, enhanced transcriptional activation by nuclear receptors, but only when GRIP1 or SRC-1a was coexpressed. Thus, CARM1 functions as a secondary coactivator through its association with p160 coactivators. CARM1 can methylate histone H3 in vitro, and a mutation in the putative S-adenosylmethionine binding domain of CARM1 substantially reduced both methyltransferase and coactivator activities. Thus, coactivator-mediated methylation of proteins in the transcription machinery may contribute to transcriptional regulation.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Chen, D -- Ma, H -- Hong, H -- Koh, S S -- Huang, S M -- Schurter, B T -- Aswad, D W -- Stallcup, M R -- AG00093/AG/NIA NIH HHS/ -- DK43093/DK/NIDDK NIH HHS/ -- NS17269/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 1999 Jun 25;284(5423):2174-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Pathology HMR 301, University of Southern California, 2011 Zonal Avenue, Los Angeles, CA 90033, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/10381882" target="_blank"〉PubMed〈/a〉

Description: Genetic variability of Plasmodium falciparum underlies its transmission success and thwarts efforts to control disease caused by this parasite. Genetic variation in antigenic, drug resistance, and pathogenesis determinants is abundant, consistent with an ancient origin of P. falciparum, whereas DNA variation at silent (synonymous) sites in coding sequences appears virtually absent, consistent with a recent origin of the parasite. To resolve this paradox, we analyzed introns and demonstrated that these are deficient in single-nucleotide polymorphisms, as are synonymous sites in coding regions. These data establish the recent origin of P. falciparum and further provide an explanation for the abundant diversity observed in antigen and other selected genes.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Volkman, S K -- Barry, A E -- Lyons, E J -- Nielsen, K M -- Thomas, S M -- Choi, M -- Thakore, S S -- Day, K P -- Wirth, D F -- Hartl, D L -- New York, N.Y. -- Science. 2001 Jul 20;293(5529):482-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉The Harvard-Oxford Malaria Genome Diversity Project, Department of Immunology and Infectious Diseases, Harvard School of Public Health, Boston, MA 02115, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/11463913" target="_blank"〉PubMed〈/a〉

Description: The PPP2R1B gene, which encodes the beta isoform of the A subunit of the serine/threonine protein phosphatase 2A (PP2A), was identified as a putative human tumor suppressor gene. Sequencing of the PPP2R1B gene, located on human chromosome 11q22-24, revealed somatic alterations in 15% (5 out of 33) of primary lung tumors, 6% (4 out of 70) of lung tumor-derived cell lines, and 15% (2 out of 13) of primary colon tumors. One deletion mutation generated a truncated PP2A-Abeta protein that was unable to bind to the catalytic subunit of the PP2A holoenzyme. The PP2R1B gene product may suppress tumor development through its role in cell cycle regulation and cellular growth control.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Wang, S S -- Esplin, E D -- Li, J L -- Huang, L -- Gazdar, A -- Minna, J -- Evans, G A -- New York, N.Y. -- Science. 1998 Oct 9;282(5387):284-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉McDermott Center for Human Growth and Development, The University of Texas Southwestern Medical Center, Dallas, Texas 75235, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/9765152" target="_blank"〉PubMed〈/a〉

Description: Review The neurodegenerative disorders, a heterogeneous group of chronic progressive diseases, are among the most puzzling and devastating illnesses in medicine. Some of these disorders, such as Alzheimer's disease, amyotrophic lateral sclerosis, the prion diseases, and Parkinson's disease, can occur sporadically and, in some instances, are caused by inheritance of gene mutations. Huntington's disease is acquired in an entirely genetic manner. Transgenic mice that express disease-causing genes recapitulate many features of these diseases. This review provides an overview of transgenic mouse models of familial amyotrophic lateral sclerosis, familial Alzheimer's disease, and Huntington's disease and the emerging insights relevant to the underlying molecular mechanisms of these diseases.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Price, D L -- Sisodia, S S -- Borchelt, D R -- NS 10580/NS/NINDS NIH HHS/ -- NS 20471/NS/NINDS NIH HHS/ -- NS 37145/NS/NINDS NIH HHS/ -- etc. -- New York, N.Y. -- Science. 1998 Nov 6;282(5391):1079-83.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Pathology, Johns Hopkins University School of Medicine, Baltimore, MD 21205, USA. dlprice@welchlink.welch.jhu.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/9804539" target="_blank"〉PubMed〈/a〉
