    Assembly and analysis of conical models for the HIV-1 core (1999)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1999-01-05
    Description: The genome of the human immunodeficiency virus (HIV) is packaged within an unusual conical core particle located at the center of the infectious virion. The core is composed of a complex of the NC (nucleocapsid) protein and genomic RNA, surrounded by a shell of the CA (capsid) protein. A method was developed for assembling cones in vitro using pure recombinant HIV-1 CA-NC fusion proteins and RNA templates. These synthetic cores are capped at both ends and appear similar in size and morphology to authentic viral cores. It is proposed that both viral and synthetic cores are organized on conical hexagonal lattices, which by Euler's theorem requires quantization of their cone angles. Electron microscopic analyses revealed that the cone angles of synthetic cores were indeed quantized into the five allowed angles. The viral core and most synthetic cones exhibited cone angles of approximately 19 degrees (the narrowest of the allowed angles). These observations suggest that the core of HIV is organized on the principles of a fullerene cone, in analogy to structures recently observed for elemental carbon.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Ganser, B K -- Li, S -- Klishko, V Y -- Finch, J T -- Sundquist, W I -- New York, N.Y. -- Science. 1999 Jan 1;283(5398):80-3.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biochemistry, University of Utah, Salt Lake City, UT 84132, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/9872746" target="_blank"〉PubMed〈/a〉

    Structure of the carboxyl-terminal dimerization domain of the HIV-1 capsid protein (1997)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1997-11-05
    Description: The carboxyl-terminal domain, residues 146 to 231, of the human immunodeficiency virus-1 (HIV-1) capsid protein [CA(146-231)] is required for capsid dimerization and viral assembly. This domain contains a stretch of 20 residues, called the major homology region (MHR), which is conserved across retroviruses and is essential for viral assembly, maturation, and infectivity. The crystal structures of CA(146-231) and CA(151-231) reveal that the globular domain is composed of four helices and an extended amino-terminal strand. CA(146-231) dimerizes through parallel packing of helix 2 across a dyad. The MHR is distinct from the dimer interface and instead forms an intricate hydrogen-bonding network that interconnects strand 1 and helices 1 and 2. Alignment of the CA(146-231) dimer with the crystal structure of the capsid amino-terminal domain provides a model for the intact protein and extends models for assembly of the central conical core of HIV-1.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Gamble, T R -- Yoo, S -- Vajdos, F F -- von Schwedler, U K -- Worthylake, D K -- Wang, H -- McCutcheon, J P -- Sundquist, W I -- Hill, C P -- R01 AI40333/AI/NIAID NIH HHS/ -- R01 AI43036/AI/NIAID NIH HHS/ -- New York, N.Y. -- Science. 1997 Oct 31;278(5339):849-53.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biochemistry, University of Utah, Salt Lake City, UT 84132, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/9346481" target="_blank"〉PubMed〈/a〉

    Global landscape of HIV-human protein complexes (2011)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2011-12-23
    Description: Human immunodeficiency virus (HIV) has a small genome and therefore relies heavily on the host cellular machinery to replicate. Identifying which host proteins and complexes come into physical contact with the viral proteins is crucial for a comprehensive understanding of how HIV rewires the host's cellular machinery during the course of infection. Here we report the use of affinity tagging and purification mass spectrometry to determine systematically the physical interactions of all 18 HIV-1 proteins and polyproteins with host proteins in two different human cell lines (HEK293 and Jurkat). Using a quantitative scoring system that we call MiST, we identified with high confidence 497 HIV-human protein-protein interactions involving 435 individual human proteins, with approximately 40% of the interactions being identified in both cell types. We found that the host proteins hijacked by HIV, especially those found interacting in both cell types, are highly conserved across primates. We uncovered a number of host complexes targeted by viral proteins, including the finding that HIV protease cleaves eIF3d, a subunit of eukaryotic translation initiation factor 3. This host protein is one of eleven identified in this analysis that act to inhibit HIV replication. This data set facilitates a more comprehensive and detailed understanding of how the host machinery is manipulated during the course of HIV infection.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3310911/" 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/PMC3310911/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Jager, Stefanie -- Cimermancic, Peter -- Gulbahce, Natali -- Johnson, Jeffrey R -- McGovern, Kathryn E -- Clarke, Starlynn C -- Shales, Michael -- Mercenne, Gaelle -- Pache, Lars -- Li, Kathy -- Hernandez, Hilda -- Jang, Gwendolyn M -- Roth, Shoshannah L -- Akiva, Eyal -- Marlett, John -- Stephens, Melanie -- D'Orso, Ivan -- Fernandes, Jason -- Fahey, Marie -- Mahon, Cathal -- O'Donoghue, Anthony J -- Todorovic, Aleksandar -- Morris, John H -- Maltby, David A -- Alber, Tom -- Cagney, Gerard -- Bushman, Frederic D -- Young, John A -- Chanda, Sumit K -- Sundquist, Wesley I -- Kortemme, Tanja -- Hernandez, Ryan D -- Craik, Charles S -- Burlingame, Alma -- Sali, Andrej -- Frankel, Alan D -- Krogan, Nevan J -- P01 AI090935/AI/NIAID NIH HHS/ -- P01 AI090935-02/AI/NIAID NIH HHS/ -- P01 GM073732-05/GM/NIGMS NIH HHS/ -- P41 GM103481/GM/NIGMS NIH HHS/ -- P41 RR001081/RR/NCRR NIH HHS/ -- P41RR001614/RR/NCRR NIH HHS/ -- P50 GM081879/GM/NIGMS NIH HHS/ -- P50 GM081879-02/GM/NIGMS NIH HHS/ -- P50 GM082250/GM/NIGMS NIH HHS/ -- P50 GM082250-05/GM/NIGMS NIH HHS/ -- P50GM081879/GM/NIGMS NIH HHS/ -- P50GM082545/GM/NIGMS NIH HHS/ -- U54 RR022220/RR/NCRR NIH HHS/ -- England -- Nature. 2011 Dec 21;481(7381):365-70. doi: 10.1038/nature10719.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Cellular and Molecular Pharmacology, University of California, San Francisco, California 94158, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/22190034" target="_blank"〉PubMed〈/a〉

    Structure of the amino-terminal core domain of the HIV-1 capsid protein (1996)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1996-07-12
    Description: The three-dimensional structure of the amino-terminal core domain (residues 1 through 151) of the human immunodeficiency virus-type 1 (HIV-1) capsid protein has been solved by multidimensional heteronuclear magnetic resonance spectroscopy. The structure is unlike those of previously characterized viral coat proteins and is composed of seven alpha helices, two beta hairpins, and an exposed partially ordered loop. The domain is shaped like an arrowhead, with the beta hairpins and loop exposed at the trailing edge and the carboxyl-terminal helix projecting from the tip. The proline residue Pro1 forms a salt bridge with a conserved, buried aspartate residue (Asp51), which suggests that the amino terminus of the protein rearranges upon proteolytic maturation. The binding site for cyclophilin A, a cellular rotamase that is packaged into the HIV-1 virion, is located on the exposed loop and encompasses the essential proline residue Pro90. In the free monomeric domain, Pro90 adopts kinetically trapped cis and trans conformations, raising the possibility that cyclophilin A catalyzes interconversion of the cis- and trans-Pro90 loop structures.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Gitti, R K -- Lee, B M -- Walker, J -- Summers, M F -- Yoo, S -- Sundquist, W I -- AI30917/AI/NIAID NIH HHS/ -- CA 42014/CA/NCI NIH HHS/ -- GM 42561/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1996 Jul 12;273(5272):231-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Howard Hughes Medical Institute and Department of Chemistry and Biochemistry, University of Maryland Baltimore County, Baltimore, MD 21228, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8662505" target="_blank"〉PubMed〈/a〉

    Structure and membrane remodeling activity of ESCRT-III helical polymers (2015)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2015-12-05
    Description: The endosomal sorting complexes required for transport (ESCRT) proteins mediate fundamental membrane remodeling events that require stabilizing negative membrane curvature. These include endosomal intralumenal vesicle formation, HIV budding, nuclear envelope closure, and cytokinetic abscission. ESCRT-III subunits perform key roles in these processes by changing conformation and polymerizing into membrane-remodeling filaments. Here, we report the 4 angstrom resolution cryogenic electron microscopy reconstruction of a one-start, double-stranded helical copolymer composed of two different human ESCRT-III subunits, charged multivesicular body protein 1B (CHMP1B) and increased sodium tolerance 1 (IST1). The inner strand comprises "open" CHMP1B subunits that interlock in an elaborate domain-swapped architecture and is encircled by an outer strand of "closed" IST1 subunits. Unlike other ESCRT-III proteins, CHMP1B and IST1 polymers form external coats on positively curved membranes in vitro and in vivo. Our analysis suggests how common ESCRT-III filament architectures could stabilize different degrees and directions of membrane curvature.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4684769/" 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/PMC4684769/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉McCullough, John -- Clippinger, Amy K -- Talledge, Nathaniel -- Skowyra, Michael L -- Saunders, Marissa G -- Naismith, Teresa V -- Colf, Leremy A -- Afonine, Pavel -- Arthur, Christopher -- Sundquist, Wesley I -- Hanson, Phyllis I -- Frost, Adam -- 1DP2GM110772-01/DP/NCCDPHP CDC HHS/ -- 1P01 GM063210/GM/NIGMS NIH HHS/ -- 2P50GM082545-06/GM/NIGMS NIH HHS/ -- DP2 GM110772/GM/NIGMS NIH HHS/ -- P01 GM063210/GM/NIGMS NIH HHS/ -- P41 RR17573/RR/NCRR NIH HHS/ -- P50 GM082545/GM/NIGMS NIH HHS/ -- R01 AI051174/AI/NIAID NIH HHS/ -- R01AI051174/AI/NIAID NIH HHS/ -- R01GM076686/GM/NIGMS NIH HHS/ -- R01GM112080/GM/NIGMS NIH HHS/ -- R01NS050717/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 2015 Dec 18;350(6267):1548-51. doi: 10.1126/science.aad8305.
