    African origin of modern humans in East Asia: a tale of 12,000 Y chromosomes (2001)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2001-05-12
    Description: To test the hypotheses of modern human origin in East Asia, we sampled 12,127 male individuals from 163 populations and typed for three Y chromosome biallelic markers (YAP, M89, and M130). All the individuals carried a mutation at one of the three sites. These three mutations (YAP+, M89T, and M130T) coalesce to another mutation (M168T), which originated in Africa about 35,000 to 89,000 years ago. Therefore, the data do not support even a minimal in situ hominid contribution in the origin of anatomically modern humans in East Asia.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Ke, Y -- Su, B -- Song, X -- Lu, D -- Chen, L -- Li, H -- Qi, C -- Marzuki, S -- Deka, R -- Underhill, P -- Xiao, C -- Shriver, M -- Lell, J -- Wallace, D -- Wells, R S -- Seielstad, M -- Oefner, P -- Zhu, D -- Jin, J -- Huang, W -- Chakraborty, R -- Chen, Z -- Jin, L -- New York, N.Y. -- Science. 2001 May 11;292(5519):1151-3.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉State Key Laboratory of Genetic Engineering, Institute of Genetics, School of Life Sciences, Fudan University, 220 Handan Road, Shanghai, China.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/11349147" target="_blank"〉PubMed〈/a〉

    Allosteric ligands for the pharmacologically dark receptors GPR68 and GPR65 (2015)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2015-11-10
    Description: At least 120 non-olfactory G-protein-coupled receptors in the human genome are 'orphans' for which endogenous ligands are unknown, and many have no selective ligands, hindering the determination of their biological functions and clinical relevance. Among these is GPR68, a proton receptor that lacks small molecule modulators for probing its biology. Using yeast-based screens against GPR68, here we identify the benzodiazepine drug lorazepam as a non-selective GPR68 positive allosteric modulator. More than 3,000 GPR68 homology models were refined to recognize lorazepam in a putative allosteric site. Docking 3.1 million molecules predicted new GPR68 modulators, many of which were confirmed in functional assays. One potent GPR68 modulator, ogerin, suppressed recall in fear conditioning in wild-type but not in GPR68-knockout mice. The same approach led to the discovery of allosteric agonists and negative allosteric modulators for GPR65. Combining physical and structure-based screening may be broadly useful for ligand discovery for understudied and orphan GPCRs.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Huang, Xi-Ping -- Karpiak, Joel -- Kroeze, Wesley K -- Zhu, Hu -- Chen, Xin -- Moy, Sheryl S -- Saddoris, Kara A -- Nikolova, Viktoriya D -- Farrell, Martilias S -- Wang, Sheng -- Mangano, Thomas J -- Deshpande, Deepak A -- Jiang, Alice -- Penn, Raymond B -- Jin, Jian -- Koller, Beverly H -- Kenakin, Terry -- Shoichet, Brian K -- Roth, Bryan L -- GM59957/GM/NIGMS NIH HHS/ -- GM71896/GM/NIGMS NIH HHS/ -- P01 HL114471/HL/NHLBI NIH HHS/ -- R01 DA017204/DA/NIDA NIH HHS/ -- R01 DA027170/DA/NIDA NIH HHS/ -- U01 MH104974/MH/NIMH NIH HHS/ -- U19MH082441/MH/NIMH NIH HHS/ -- U54 HD079124/HD/NICHD NIH HHS/ -- England -- Nature. 2015 Nov 26;527(7579):477-83. doi: 10.1038/nature15699.

    OTUD7B controls non-canonical NF-kappaB activation through deubiquitination of TRAF3 (2013)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2013-01-22
    Description: The non-canonical NF-kappaB pathway forms a major arm of NF-kappaB signalling that mediates important biological functions, including lymphoid organogenesis, B-lymphocyte function, and cell growth and survival. Activation of the non-canonical NF-kappaB pathway involves degradation of an inhibitory protein, TNF receptor-associated factor 3 (TRAF3), but how this signalling event is controlled is still unknown. Here we have identified the deubiquitinase OTUD7B as a pivotal regulator of the non-canonical NF-kappaB pathway. OTUD7B deficiency in mice has no appreciable effect on canonical NF-kappaB activation but causes hyperactivation of non-canonical NF-kappaB. In response to non-canonical NF-kappaB stimuli, OTUD7B binds and deubiquitinates TRAF3, thereby inhibiting TRAF3 proteolysis and preventing aberrant non-canonical NF-kappaB activation. Consequently, the OTUD7B deficiency results in B-cell hyper-responsiveness to antigens, lymphoid follicular hyperplasia in the intestinal mucosa, and elevated host-defence ability against an intestinal bacterial pathogen, Citrobacter rodentium. These findings establish OTUD7B as a crucial regulator of signal-induced non-canonical NF-kappaB activation and indicate a mechanism of immune regulation that involves OTUD7B-mediated deubiquitination and stabilization of TRAF3.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3578967/" 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/PMC3578967/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hu, Hongbo -- Brittain, George C -- Chang, Jae-Hoon -- Puebla-Osorio, Nahum -- Jin, Jin -- Zal, Anna -- Xiao, Yichuan -- Cheng, Xuhong -- Chang, Mikyoung -- Fu, Yang-Xin -- Zal, Tomasz -- Zhu, Chengming -- Sun, Shao-Cong -- AI057555/AI/NIAID NIH HHS/ -- AI064639/AI/NIAID NIH HHS/ -- CA137059/CA/NCI NIH HHS/ -- GM84459/GM/NIGMS NIH HHS/ -- P30 CA016672/CA/NCI NIH HHS/ -- R01 CA137059/CA/NCI NIH HHS/ -- R01 GM084459/GM/NIGMS NIH HHS/ -- T32 CA009598/CA/NCI NIH HHS/ -- T32CA009598/CA/NCI NIH HHS/ -- England -- Nature. 2013 Feb 21;494(7437):371-4. doi: 10.1038/nature11831.

    Structure of malaria invasion protein RH5 with erythrocyte basigin and blocking antibodies (2014)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2014-08-19
    Description: Invasion of host erythrocytes is essential to the life cycle of Plasmodium parasites and development of the pathology of malaria. The stages of erythrocyte invasion, including initial contact, apical reorientation, junction formation, and active invagination, are directed by coordinated release of specialized apical organelles and their parasite protein contents. Among these proteins, and central to invasion by all species, are two parasite protein families, the reticulocyte-binding protein homologue (RH) and erythrocyte-binding like proteins, which mediate host-parasite interactions. RH5 from Plasmodium falciparum (PfRH5) is the only member of either family demonstrated to be necessary for erythrocyte invasion in all tested strains, through its interaction with the erythrocyte surface protein basigin (also known as CD147 and EMMPRIN). Antibodies targeting PfRH5 or basigin efficiently block parasite invasion in vitro, making PfRH5 an excellent vaccine candidate. Here we present crystal structures of PfRH5 in complex with basigin and two distinct inhibitory antibodies. PfRH5 adopts a novel fold in which two three-helical bundles come together in a kite-like architecture, presenting binding sites for basigin and inhibitory antibodies at one tip. This provides the first structural insight into erythrocyte binding by the Plasmodium RH protein family and identifies novel inhibitory epitopes to guide design of a new generation of vaccines against the blood-stage parasite.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4240730/" 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/PMC4240730/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Wright, Katherine E -- Hjerrild, Kathryn A -- Bartlett, Jonathan -- Douglas, Alexander D -- Jin, Jing -- Brown, Rebecca E -- Illingworth, Joseph J -- Ashfield, Rebecca -- Clemmensen, Stine B -- de Jongh, Willem A -- Draper, Simon J -- Higgins, Matthew K -- 089455/2/09/z/Wellcome Trust/United Kingdom -- 101020/Wellcome Trust/United Kingdom -- 101020/Z/13/Z/Wellcome Trust/United Kingdom -- G1000527/Medical Research Council/United Kingdom -- MR/K025554/1/Medical Research Council/United Kingdom -- England -- Nature. 2014 Nov 20;515(7527):427-30. doi: 10.1038/nature13715.

    Draft genome of the filarial nematode parasite Brugia malayi (2007)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2007-09-22
    Description: Parasitic nematodes that cause elephantiasis and river blindness threaten hundreds of millions of people in the developing world. We have sequenced the approximately 90 megabase (Mb) genome of the human filarial parasite Brugia malayi and predict approximately 11,500 protein coding genes in 71 Mb of robustly assembled sequence. Comparative analysis with the free-living, model nematode Caenorhabditis elegans revealed that, despite these genes having maintained little conservation of local synteny during approximately 350 million years of evolution, they largely remain in linkage on chromosomal units. More than 100 conserved operons were identified. Analysis of the predicted proteome provides evidence for adaptations of B. malayi to niches in its human and vector hosts and insights into the molecular basis of a mutualistic relationship with its Wolbachia endosymbiont. These findings offer a foundation for rational drug design.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2613796/" 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/PMC2613796/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Ghedin, Elodie -- Wang, Shiliang -- Spiro, David -- Caler, Elisabet -- Zhao, Qi -- Crabtree, Jonathan -- Allen, Jonathan E -- Delcher, Arthur L -- Guiliano, David B -- Miranda-Saavedra, Diego -- Angiuoli, Samuel V -- Creasy, Todd -- Amedeo, Paolo -- Haas, Brian -- El-Sayed, Najib M -- Wortman, Jennifer R -- Feldblyum, Tamara -- Tallon, Luke -- Schatz, Michael -- Shumway, Martin -- Koo, Hean -- Salzberg, Steven L -- Schobel, Seth -- Pertea, Mihaela -- Pop, Mihai -- White, Owen -- Barton, Geoffrey J -- Carlow, Clotilde K S -- Crawford, Michael J -- Daub, Jennifer -- Dimmic, Matthew W -- Estes, Chris F -- Foster, Jeremy M -- Ganatra, Mehul -- Gregory, William F -- Johnson, Nicholas M -- Jin, Jinming -- Komuniecki, Richard -- Korf, Ian -- Kumar, Sanjay -- Laney, Sandra -- Li, Ben-Wen -- Li, Wen -- Lindblom, Tim H -- Lustigman, Sara -- Ma, Dong -- Maina, Claude V -- Martin, David M A -- McCarter, James P -- McReynolds, Larry -- Mitreva, Makedonka -- Nutman, Thomas B -- Parkinson, John -- Peregrin-Alvarez, Jose M -- Poole, Catherine -- Ren, Qinghu -- Saunders, Lori -- Sluder, Ann E -- Smith, Katherine -- Stanke, Mario -- Unnasch, Thomas R -- Ware, Jenna -- Wei, Aguan D -- Weil, Gary -- Williams, Deryck J -- Zhang, Yinhua -- Williams, Steven A -- Fraser-Liggett, Claire -- Slatko, Barton -- Blaxter, Mark L -- Scott, Alan L -- R01 AI048562/AI/NIAID NIH HHS/ -- R01 AI048562-09/AI/NIAID NIH HHS/ -- R01 LM006845/LM/NLM NIH HHS/ -- R01 LM006845-08/LM/NLM NIH HHS/ -- R01 LM007938/LM/NLM NIH HHS/ -- R01 LM007938-04/LM/NLM NIH HHS/ -- R15 ES013128/ES/NIEHS NIH HHS/ -- R15 ES013128-01/ES/NIEHS NIH HHS/ -- U01 AI048828/AI/NIAID NIH HHS/ -- U01-AI50903/AI/NIAID NIH HHS/ -- New York, N.Y. -- Science. 2007 Sep 21;317(5845):1756-60.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Division of Infectious Diseases, University of Pittsburgh School of Medicine, Pittsburgh, PA 15261, USA.
