    A divergent calponin homology (NN-CH) domain defines a novel family: implications for evolution of ciliary IFT complex B proteins (2014)
    Oxford University Press
    Details
    Publication Date: 2014-03-28
    Description: Motivation: Microtubules are dynamic polymers of tubulin dimers that undergo continuous assembly and disassembly. A mounting number of microtubule-associated proteins (MAPs) regulate the dynamic behavior of microtubules and hence the assembly and disassembly of disparate microtubule structures within the cell. Despite recent advances in identification and functional characterization of MAPs, a substantial number of microtubule accessory factors have not been functionally annotated. Here, using profile-to-profile comparisons and structure modeling, we show that the yeast outer kinetochore components NDC80 and NUF2 share evolutionary ancestry with a novel protein family in mammals comprising, besides NDC80/HEC1 and NUF2, three Intraflagellar Transport (IFT) complex B subunits (IFT81, IFT57, CLUAP1) as well as six proteins with poorly defined function (FAM98A-C, CCDC22, CCDC93 and C14orf166). We show that these proteins consist of a divergent N-terminal calponin homology (CH)-like domain adjoined to an array of C-terminal heptad repeats predicted to form a coiled-coil arrangement. We have named the divergent CH-like domain NN–CH after the founding members NDC80 and NUF2.

    Self-assembly of a nanoscale DNA box with a controllable lid (2009)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2009-05-09
    Description: The unique structural motifs and self-recognition properties of DNA can be exploited to generate self-assembling DNA nanostructures of specific shapes using a 'bottom-up' approach. Several assembly strategies have been developed for building complex three-dimensional (3D) DNA nanostructures. Recently, the DNA 'origami' method was used to build two-dimensional addressable DNA structures of arbitrary shape that can be used as platforms to arrange nanomaterials with high precision and specificity. A long-term goal of this field has been to construct fully addressable 3D DNA nanostructures. Here we extend the DNA origami method into three dimensions by creating an addressable DNA box 42 x 36 x 36 nm(3) in size that can be opened in the presence of externally supplied DNA 'keys'. We thoroughly characterize the structure of this DNA box using cryogenic transmission electron microscopy, small-angle X-ray scattering and atomic force microscopy, and use fluorescence resonance energy transfer to optically monitor the opening of the lid. Controlled access to the interior compartment of this DNA nanocontainer could yield several interesting applications, for example as a logic sensor for multiple-sequence signals or for the controlled release of nanocargos.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Andersen, Ebbe S -- Dong, Mingdong -- Nielsen, Morten M -- Jahn, Kasper -- Subramani, Ramesh -- Mamdouh, Wael -- Golas, Monika M -- Sander, Bjoern -- Stark, Holger -- Oliveira, Cristiano L P -- Pedersen, Jan Skov -- Birkedal, Victoria -- Besenbacher, Flemming -- Gothelf, Kurt V -- Kjems, Jorgen -- England -- Nature. 2009 May 7;459(7243):73-6. doi: 10.1038/nature07971.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Danish National Research Foundation: Centre for DNA Nanotechnology.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19424153" target="_blank"〉PubMed〈/a〉

    A high-resolution map of human evolutionary constraint using 29 mammals (2011)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2011-10-14
    Description: The comparison of related genomes has emerged as a powerful lens for genome interpretation. Here we report the sequencing and comparative analysis of 29 eutherian genomes. We confirm that at least 5.5% of the human genome has undergone purifying selection, and locate constrained elements covering approximately 4.2% of the genome. We use evolutionary signatures and comparisons with experimental data sets to suggest candidate functions for approximately 60% of constrained bases. These elements reveal a small number of new coding exons, candidate stop codon readthrough events and over 10,000 regions of overlapping synonymous constraint within protein-coding exons. We find 220 candidate RNA structural families, and nearly a million elements overlapping potential promoter, enhancer and insulator regions. We report specific amino acid residues that have undergone positive selection, 280,000 non-coding elements exapted from mobile elements and more than 1,000 primate- and human-accelerated elements. Overlap with disease-associated variants indicates that our findings will be relevant for studies of human biology, health and disease.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3207357/" 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/PMC3207357/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lindblad-Toh, Kerstin -- Garber, Manuel -- Zuk, Or -- Lin, Michael F -- Parker, Brian J -- Washietl, Stefan -- Kheradpour, Pouya -- Ernst, Jason -- Jordan, Gregory -- Mauceli, Evan -- Ward, Lucas D -- Lowe, Craig B -- Holloway, Alisha K -- Clamp, Michele -- Gnerre, Sante -- Alfoldi, Jessica -- Beal, Kathryn -- Chang, Jean -- Clawson, Hiram -- Cuff, James -- Di Palma, Federica -- Fitzgerald, Stephen -- Flicek, Paul -- Guttman, Mitchell -- Hubisz, Melissa J -- Jaffe, David B -- Jungreis, Irwin -- Kent, W James -- Kostka, Dennis -- Lara, Marcia -- Martins, Andre L -- Massingham, Tim -- Moltke, Ida -- Raney, Brian J -- Rasmussen, Matthew D -- Robinson, Jim -- Stark, Alexander -- Vilella, Albert J -- Wen, Jiayu -- Xie, Xiaohui -- Zody, Michael C -- Broad Institute Sequencing Platform and Whole Genome Assembly Team -- Baldwin, Jen -- Bloom, Toby -- Chin, Chee Whye -- Heiman, Dave -- Nicol, Robert -- Nusbaum, Chad -- Young, Sarah -- Wilkinson, Jane -- Worley, Kim C -- Kovar, Christie L -- Muzny, Donna M -- Gibbs, Richard A -- Baylor College of Medicine Human Genome Sequencing Center Sequencing Team -- Cree, Andrew -- Dihn, Huyen H -- Fowler, Gerald -- Jhangiani, Shalili -- Joshi, Vandita -- Lee, Sandra -- Lewis, Lora R -- Nazareth, Lynne V -- Okwuonu, Geoffrey -- Santibanez, Jireh -- Warren, Wesley C -- Mardis, Elaine R -- Weinstock, George M -- Wilson, Richard K -- Genome Institute at Washington University -- Delehaunty, Kim -- Dooling, David -- Fronik, Catrina -- Fulton, Lucinda -- Fulton, Bob -- Graves, Tina -- Minx, Patrick -- Sodergren, Erica -- Birney, Ewan -- Margulies, Elliott H -- Herrero, Javier -- Green, Eric D -- Haussler, David -- Siepel, Adam -- Goldman, Nick -- Pollard, Katherine S -- Pedersen, Jakob S -- Lander, Eric S -- Kellis, Manolis -- 095908/Wellcome Trust/United Kingdom -- GM82901/GM/NIGMS NIH HHS/ -- R01 HG003474/HG/NHGRI NIH HHS/ -- R01 HG004037/HG/NHGRI NIH HHS/ -- U54 HG003067/HG/NHGRI NIH HHS/ -- U54 HG003067-09/HG/NHGRI NIH HHS/ -- U54 HG003273/HG/NHGRI NIH HHS/ -- Howard Hughes Medical Institute/ -- England -- Nature. 2011 Oct 12;478(7370):476-82. doi: 10.1038/nature10530.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Broad Institute of Harvard and Massachusetts Institute of Technology, 7 Cambridge Center, Cambridge, Massachusetts 02142, USA. kersli@broadinstitute.org〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/21993624" target="_blank"〉PubMed〈/a〉

    Inclusive fitness theory and eusociality (2011)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2011-03-25
    Description: Arising from M. A. Nowak, C. E. Tarnita & E. O. Wilson 466, 1057-1062 (2010); Nowak et al. reply. Nowak et al. argue that inclusive fitness theory has been of little value in explaining the natural world, and that it has led to negligible progress in explaining the evolution of eusociality. However, we believe that their arguments are based upon a misunderstanding of evolutionary theory and a misrepresentation of the empirical literature. We will focus our comments on three general issues.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3836173/" 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/PMC3836173/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Abbot, Patrick -- Abe, Jun -- Alcock, John -- Alizon, Samuel -- Alpedrinha, Joao A C -- Andersson, Malte -- Andre, Jean-Baptiste -- van Baalen, Minus -- Balloux, Francois -- Balshine, Sigal -- Barton, Nick -- Beukeboom, Leo W -- Biernaskie, Jay M -- Bilde, Trine -- Borgia, Gerald -- Breed, Michael -- Brown, Sam -- Bshary, Redouan -- Buckling, Angus -- Burley, Nancy T -- Burton-Chellew, Max N -- Cant, Michael A -- Chapuisat, Michel -- Charnov, Eric L -- Clutton-Brock, Tim -- Cockburn, Andrew -- Cole, Blaine J -- Colegrave, Nick -- Cosmides, Leda -- Couzin, Iain D -- Coyne, Jerry A -- Creel, Scott -- Crespi, Bernard -- Curry, Robert L -- Dall, Sasha R X -- Day, Troy -- Dickinson, Janis L -- Dugatkin, Lee Alan -- El Mouden, Claire -- Emlen, Stephen T -- Evans, Jay -- Ferriere, Regis -- Field, Jeremy -- Foitzik, Susanne -- Foster, Kevin -- Foster, William A -- Fox, Charles W -- Gadau, Juergen -- Gandon, Sylvain -- Gardner, Andy -- Gardner, Michael G -- Getty, Thomas -- Goodisman, Michael A D -- Grafen, Alan -- Grosberg, Rick -- Grozinger, Christina M -- Gouyon, Pierre-Henri -- Gwynne, Darryl -- Harvey, Paul H -- Hatchwell, Ben J -- Heinze, Jurgen -- Helantera, Heikki -- Helms, Ken R -- Hill, Kim -- Jiricny, Natalie -- Johnstone, Rufus A -- Kacelnik, Alex -- Kiers, E Toby -- Kokko, Hanna -- Komdeur, Jan -- Korb, Judith -- Kronauer, Daniel -- Kummerli, Rolf -- Lehmann, Laurent -- Linksvayer, Timothy A -- Lion, Sebastien -- Lyon, Bruce -- Marshall, James A R -- McElreath, Richard -- Michalakis, Yannis -- Michod, Richard E -- Mock, Douglas -- Monnin, Thibaud -- Montgomerie, Robert -- Moore, Allen J -- Mueller, Ulrich G -- Noe, Ronald -- Okasha, Samir -- Pamilo, Pekka -- Parker, Geoff A -- Pedersen, Jes S -- Pen, Ido -- Pfennig, David -- Queller, David C -- Rankin, Daniel J -- Reece, Sarah E -- Reeve, Hudson K -- Reuter, Max -- Roberts, Gilbert -- Robson, Simon K A -- Roze, Denis -- Rousset, Francois -- Rueppell, Olav -- Sachs, Joel L -- Santorelli, Lorenzo -- Schmid-Hempel, Paul -- Schwarz, Michael P -- Scott-Phillips, Tom -- Shellmann-Sherman, Janet -- Sherman, Paul W -- Shuker, David M -- Smith, Jeff -- Spagna, Joseph C -- Strassmann, Beverly -- Suarez, Andrew V -- Sundstrom, Liselotte -- Taborsky, Michael -- Taylor, Peter -- Thompson, Graham -- Tooby, John -- Tsutsui, Neil D -- Tsuji, Kazuki -- Turillazzi, Stefano -- Ubeda, Francisco -- Vargo, Edward L -- Voelkl, Bernard -- Wenseleers, Tom -- West, Stuart A -- West-Eberhard, Mary Jane -- Westneat, David F -- Wiernasz, Diane C -- Wild, Geoff -- Wrangham, Richard -- Young, Andrew J -- Zeh, David W -- Zeh, Jeanne A -- Zink, Andrew -- BB/H022716/1/Biotechnology and Biological Sciences Research Council/United Kingdom -- England -- Nature. 2011 Mar 24;471(7339):E1-4; author reply E9-10. doi: 10.1038/nature09831.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/21430721" target="_blank"〉PubMed〈/a〉

    Structure of the haptoglobin-haemoglobin complex (2012)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2012-08-28
    Description: Red cell haemoglobin is the fundamental oxygen-transporting molecule in blood, but also a potentially tissue-damaging compound owing to its highly reactive haem groups. During intravascular haemolysis, such as in malaria and haemoglobinopathies, haemoglobin is released into the plasma, where it is captured by the protective acute-phase protein haptoglobin. This leads to formation of the haptoglobin-haemoglobin complex, which represents a virtually irreversible non-covalent protein-protein interaction. Here we present the crystal structure of the dimeric porcine haptoglobin-haemoglobin complex determined at 2.9 A resolution. This structure reveals that haptoglobin molecules dimerize through an unexpected beta-strand swap between two complement control protein (CCP) domains, defining a new fusion CCP domain structure. The haptoglobin serine protease domain forms extensive interactions with both the alpha- and beta-subunits of haemoglobin, explaining the tight binding between haptoglobin and haemoglobin. The haemoglobin-interacting region in the alphabeta dimer is highly overlapping with the interface between the two alphabeta dimers that constitute the native haemoglobin tetramer. Several haemoglobin residues prone to oxidative modification after exposure to haem-induced reactive oxygen species are buried in the haptoglobin-haemoglobin interface, thus showing a direct protective role of haptoglobin. The haptoglobin loop previously shown to be essential for binding of haptoglobin-haemoglobin to the macrophage scavenger receptor CD163 (ref. 3) protrudes from the surface of the distal end of the complex, adjacent to the associated haemoglobin alpha-subunit. Small-angle X-ray scattering measurements of human haptoglobin-haemoglobin bound to the ligand-binding fragment of CD163 confirm receptor binding in this area, and show that the rigid dimeric complex can bind two receptors. Such receptor cross-linkage may facilitate scavenging and explain the increased functional affinity of multimeric haptoglobin-haemoglobin for CD163 (ref. 4).〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Andersen, Christian Brix Folsted -- Torvund-Jensen, Morten -- Nielsen, Marianne Jensby -- de Oliveira, Cristiano Luis Pinto -- Hersleth, Hans-Petter -- Andersen, Niels Hojmark -- Pedersen, Jan Skov -- Andersen, Gregers Rom -- Moestrup, Soren Kragh -- England -- Nature. 2012 Sep 20;489(7416):456-9. doi: 10.1038/nature11369.

    Mechanism of Trypanosoma brucei gambiense resistance to human serum (2013)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2013-08-24
    Description: The African parasite Trypanosoma brucei gambiense accounts for 97% of human sleeping sickness cases. T. b. gambiense resists the specific human innate immunity acting against several other tsetse-fly-transmitted trypanosome species such as T. b. brucei, the causative agent of nagana disease in cattle. Human immunity to some African trypanosomes is due to two serum complexes designated trypanolytic factors (TLF-1 and -2), which both contain haptoglobin-related protein (HPR) and apolipoprotein LI (APOL1). Whereas HPR association with haemoglobin (Hb) allows TLF-1 binding and uptake via the trypanosome receptor TbHpHbR (ref. 5), TLF-2 enters trypanosomes independently of TbHpHbR (refs 4, 5). APOL1 kills trypanosomes after insertion into endosomal/lysosomal membranes. Here we report that T. b. gambiense resists TLFs via a hydrophobic beta-sheet of the T. b. gambiense-specific glycoprotein (TgsGP), which prevents APOL1 toxicity and induces stiffening of membranes upon interaction with lipids. Two additional features contribute to resistance to TLFs: reduction of sensitivity to APOL1 requiring cysteine protease activity, and TbHpHbR inactivation due to a L210S substitution. According to such a multifactorial defence mechanism, transgenic expression of T. b. brucei TbHpHbR in T. b. gambiense did not cause parasite lysis in normal human serum. However, these transgenic parasites were killed in hypohaptoglobinaemic serum, after high TLF-1 uptake in the absence of haptoglobin (Hp) that competes for Hb and receptor binding. TbHpHbR inactivation preventing high APOL1 loading in hypohaptoglobinaemic serum may have evolved because of the overlapping endemic area of T. b. gambiense infection and malaria, the main cause of haemolysis-induced hypohaptoglobinaemia in western and central Africa.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Uzureau, Pierrick -- Uzureau, Sophie -- Lecordier, Laurence -- Fontaine, Frederic -- Tebabi, Patricia -- Homble, Fabrice -- Grelard, Axelle -- Zhendre, Vanessa -- Nolan, Derek P -- Lins, Laurence -- Crowet, Jean-Marc -- Pays, Annette -- Felu, Cecile -- Poelvoorde, Philippe -- Vanhollebeke, Benoit -- Moestrup, Soren K -- Lyngso, Jeppe -- Pedersen, Jan Skov -- Mottram, Jeremy C -- Dufourc, Erick J -- Perez-Morga, David -- Pays, Etienne -- 085349/Wellcome Trust/United Kingdom -- England -- Nature. 2013 Sep 19;501(7467):430-4. doi: 10.1038/nature12516.

    Structure of the exon junction core complex with a trapped DEAD-box ATPase bound to RNA (2006)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2006-08-26
    Description: In higher eukaryotes, a multiprotein exon junction complex is deposited on spliced messenger RNAs. The complex is organized around a stable core, which serves as a binding platform for numerous factors that influence messenger RNA function. Here, we present the crystal structure of a tetrameric exon junction core complex containing the DEAD-box adenosine triphosphatase (ATPase) eukaryotic initiation factor 4AIII (eIF4AIII) bound to an ATP analog, MAGOH, Y14, a fragment of MLN51, and a polyuracil mRNA mimic. eIF4AIII interacts with the phosphate-ribose backbone of six consecutive nucleotides and prevents part of the bound RNA from being double stranded. The MAGOH and Y14 subunits lock eIF4AIII in a prehydrolysis state, and activation of the ATPase probably requires only modest conformational changes in eIF4AIII motif I.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Andersen, Christian B F -- Ballut, Lionel -- Johansen, Jesper S -- Chamieh, Hala -- Nielsen, Klaus H -- Oliveira, Cristiano L P -- Pedersen, Jan Skov -- Seraphin, Bertrand -- Le Hir, Herve -- Andersen, Gregers Rom -- New York, N.Y. -- Science. 2006 Sep 29;313(5795):1968-72.

    Ancient human genome sequence of an extinct Palaeo-Eskimo (2010)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2010-02-12
    Description: We report here the genome sequence of an ancient human. Obtained from approximately 4,000-year-old permafrost-preserved hair, the genome represents a male individual from the first known culture to settle in Greenland. Sequenced to an average depth of 20x, we recover 79% of the diploid genome, an amount close to the practical limit of current sequencing technologies. We identify 353,151 high-confidence single-nucleotide polymorphisms (SNPs), of which 6.8% have not been reported previously. We estimate raw read contamination to be no higher than 0.8%. We use functional SNP assessment to assign possible phenotypic characteristics of the individual that belonged to a culture whose location has yielded only trace human remains. We compare the high-confidence SNPs to those of contemporary populations to find the populations most closely related to the individual. This provides evidence for a migration from Siberia into the New World some 5,500 years ago, independent of that giving rise to the modern Native Americans and Inuit.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3951495/" 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/PMC3951495/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Rasmussen, Morten -- Li, Yingrui -- Lindgreen, Stinus -- Pedersen, Jakob Skou -- Albrechtsen, Anders -- Moltke, Ida -- Metspalu, Mait -- Metspalu, Ene -- Kivisild, Toomas -- Gupta, Ramneek -- Bertalan, Marcelo -- Nielsen, Kasper -- Gilbert, M Thomas P -- Wang, Yong -- Raghavan, Maanasa -- Campos, Paula F -- Kamp, Hanne Munkholm -- Wilson, Andrew S -- Gledhill, Andrew -- Tridico, Silvana -- Bunce, Michael -- Lorenzen, Eline D -- Binladen, Jonas -- Guo, Xiaosen -- Zhao, Jing -- Zhang, Xiuqing -- Zhang, Hao -- Li, Zhuo -- Chen, Minfeng -- Orlando, Ludovic -- Kristiansen, Karsten -- Bak, Mads -- Tommerup, Niels -- Bendixen, Christian -- Pierre, Tracey L -- Gronnow, Bjarne -- Meldgaard, Morten -- Andreasen, Claus -- Fedorova, Sardana A -- Osipova, Ludmila P -- Higham, Thomas F G -- Ramsey, Christopher Bronk -- Hansen, Thomas V O -- Nielsen, Finn C -- Crawford, Michael H -- Brunak, Soren -- Sicheritz-Ponten, Thomas -- Villems, Richard -- Nielsen, Rasmus -- Krogh, Anders -- Wang, Jun -- Willerslev, Eske -- R01 HG003229/HG/NHGRI NIH HHS/ -- R01 HG003229-05/HG/NHGRI NIH HHS/ -- England -- Nature. 2010 Feb 11;463(7282):757-62. doi: 10.1038/nature08835.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Centre for GeoGenetics, Natural History Museum of Denmark and Department of Biology, University of Copenhagen, Universitetsparken 15, DK-2100 Copenhagen, Denmark.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/20148029" target="_blank"〉PubMed〈/a〉
