    Global efforts in structural genomics (2001)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2001-10-06
    Description: A worldwide initiative in structural genomics aims to capitalize on the recent successes of the genome projects. Substantial new investments in structural genomics in the past 2 years indicate the high level of support for these international efforts. Already, enormous progress has been made on high-throughput methodologies and technologies that will speed up macromolecular structure determinations. Recent international meetings have resulted in the formation of an International Structural Genomics Organization to formulate policy and foster cooperation between the public and private efforts.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Stevens, R C -- Yokoyama, S -- Wilson, I A -- P50 GM62411/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2001 Oct 5;294(5540):89-92.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Joint Center for Structural Genomics, Scripps Research Institute, 10550 North Torrey Pines Road, La Jolla, CA 92037, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/11588249" target="_blank"〉PubMed〈/a〉

    Structural adaptations in a membrane enzyme that terminates endocannabinoid signaling (2002)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2002-12-03
    Description: Cellular communication in the nervous system is mediated by chemical messengers that include amino acids, monoamines, peptide hormones, and lipids. An interesting question is how neurons regulate signals that are transmitted by membrane-embedded lipids. Here, we report the 2.8 angstrom crystal structure of the integral membrane protein fatty acid amide hydrolase (FAAH), an enzyme that degrades members of the endocannabinoid class of signaling lipids and terminates their activity. The structure of FAAH complexed with an arachidonyl inhibitor reveals how a set of discrete structural alterations allows this enzyme, in contrast to soluble hydrolases of the same family, to integrate into cell membranes and establish direct access to the bilayer from its active site.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Bracey, Michael H -- Hanson, Michael A -- Masuda, Kim R -- Stevens, Raymond C -- Cravatt, Benjamin F -- R01 DA013173/DA/NIDA NIH HHS/ -- R01 DA013173-02/DA/NIDA NIH HHS/ -- New York, N.Y. -- Science. 2002 Nov 29;298(5599):1793-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Cell Biology, Skaggs Institute for Chemical Biology, Scripps Research Institute, 10550 North Torrey Pines Road, La Jolla, CA 92037, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/12459591" target="_blank"〉PubMed〈/a〉

    Crystal structure of the anti-viral APOBEC3G catalytic domain and functional implications (2008)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2008-10-14
    Description: The APOBEC family members are involved in diverse biological functions. APOBEC3G restricts the replication of human immunodeficiency virus (HIV), hepatitis B virus and retroelements by cytidine deamination on single-stranded DNA or by RNA binding. Here we report the high-resolution crystal structure of the carboxy-terminal deaminase domain of APOBEC3G (APOBEC3G-CD2) purified from Escherichia coli. The APOBEC3G-CD2 structure has a five-stranded beta-sheet core that is common to all known deaminase structures and closely resembles the structure of another APOBEC protein, APOBEC2 (ref. 5). A comparison of APOBEC3G-CD2 with other deaminase structures shows a structural conservation of the active-site loops that are directly involved in substrate binding. In the X-ray structure, these APOBEC3G active-site loops form a continuous 'substrate groove' around the active centre. The orientation of this putative substrate groove differs markedly (by 90 degrees) from the groove predicted by the NMR structure. We have introduced mutations around the groove, and have identified residues involved in substrate specificity, single-stranded DNA binding and deaminase activity. These results provide a basis for understanding the underlying mechanisms of substrate specificity for the APOBEC family.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2714533/" 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/PMC2714533/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Holden, Lauren G -- Prochnow, Courtney -- Chang, Y Paul -- Bransteitter, Ronda -- Chelico, Linda -- Sen, Udayaditya -- Stevens, Raymond C -- Goodman, Myron F -- Chen, Xiaojiang S -- R01 AI055926/AI/NIAID NIH HHS/ -- R01 AI055926-05/AI/NIAID NIH HHS/ -- England -- Nature. 2008 Nov 6;456(7218):121-4. doi: 10.1038/nature07357.

    Biased signaling pathways in beta2-adrenergic receptor characterized by 19F-NMR (2012)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2012-01-24
    Description: Extracellular ligand binding to G protein-coupled receptors (GPCRs) modulates G protein and beta-arrestin signaling by changing the conformational states of the cytoplasmic region of the receptor. Using site-specific (19)F-NMR (fluorine-19 nuclear magnetic resonance) labels in the beta(2)-adrenergic receptor (beta(2)AR) in complexes with various ligands, we observed that the cytoplasmic ends of helices VI and VII adopt two major conformational states. Changes in the NMR signals reveal that agonist binding primarily shifts the equilibrium toward the G protein-specific active state of helix VI. In contrast, beta-arrestin-biased ligands predominantly impact the conformational states of helix VII. The selective effects of different ligands on the conformational equilibria involving helices VI and VII provide insights into the long-range structural plasticity of beta(2)AR in partial and biased agonist signaling.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3292700/" 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/PMC3292700/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Liu, Jeffrey J -- Horst, Reto -- Katritch, Vsevolod -- Stevens, Raymond C -- Wuthrich, Kurt -- P50 GM073197/GM/NIGMS NIH HHS/ -- P50 GM073197-08/GM/NIGMS NIH HHS/ -- U54 GM094618/GM/NIGMS NIH HHS/ -- U54 GM094618-02/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2012 Mar 2;335(6072):1106-10. doi: 10.1126/science.1215802.

    Structural basis for molecular recognition at serotonin receptors (2013)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2013-03-23
    Description: Serotonin or 5-hydroxytryptamine (5-HT) regulates a wide spectrum of human physiology through the 5-HT receptor family. We report the crystal structures of the human 5-HT1B G protein-coupled receptor bound to the agonist antimigraine medications ergotamine and dihydroergotamine. The structures reveal similar binding modes for these ligands, which occupy the orthosteric pocket and an extended binding pocket close to the extracellular loops. The orthosteric pocket is formed by residues conserved in the 5-HT receptor family, clarifying the family-wide agonist activity of 5-HT. Compared with the structure of the 5-HT2B receptor, the 5-HT1B receptor displays a 3 angstrom outward shift at the extracellular end of helix V, resulting in a more open extended pocket that explains subtype selectivity. Together with docking and mutagenesis studies, these structures provide a comprehensive structural basis for understanding receptor-ligand interactions and designing subtype-selective serotonergic drugs.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3644373/" 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/PMC3644373/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Wang, Chong -- Jiang, Yi -- Ma, Jinming -- Wu, Huixian -- Wacker, Daniel -- Katritch, Vsevolod -- Han, Gye Won -- Liu, Wei -- Huang, Xi-Ping -- Vardy, Eyal -- McCorvy, John D -- Gao, Xiang -- Zhou, X Edward -- Melcher, Karsten -- Zhang, Chenghai -- Bai, Fang -- Yang, Huaiyu -- Yang, Linlin -- Jiang, Hualiang -- Roth, Bryan L -- Cherezov, Vadim -- Stevens, Raymond C -- Xu, H Eric -- P50 GM073197/GM/NIGMS NIH HHS/ -- R01 DA027170/DA/NIDA NIH HHS/ -- R01 DA27170/DA/NIDA NIH HHS/ -- R01 DK071662/DK/NIDDK NIH HHS/ -- R01 MH061887/MH/NIMH NIH HHS/ -- R01 MH61887/MH/NIMH NIH HHS/ -- U19 MH082441/MH/NIMH NIH HHS/ -- U19 MH82441/MH/NIMH NIH HHS/ -- U54 GM094618/GM/NIGMS NIH HHS/ -- Y1-CO-1020/CO/NCI NIH HHS/ -- Y1-GM-1104/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2013 May 3;340(6132):610-4. doi: 10.1126/science.1232807.

    High-resolution crystal structure of an engineered human beta2-adrenergic G protein-coupled receptor (2007)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2007-10-27
    Description: Heterotrimeric guanine nucleotide-binding protein (G protein)-coupled receptors constitute the largest family of eukaryotic signal transduction proteins that communicate across the membrane. We report the crystal structure of a human beta2-adrenergic receptor-T4 lysozyme fusion protein bound to the partial inverse agonist carazolol at 2.4 angstrom resolution. The structure provides a high-resolution view of a human G protein-coupled receptor bound to a diffusible ligand. Ligand-binding site accessibility is enabled by the second extracellular loop, which is held out of the binding cavity by a pair of closely spaced disulfide bridges and a short helical segment within the loop. Cholesterol, a necessary component for crystallization, mediates an intriguing parallel association of receptor molecules in the crystal lattice. Although the location of carazolol in the beta2-adrenergic receptor is very similar to that of retinal in rhodopsin, structural differences in the ligand-binding site and other regions highlight the challenges in using rhodopsin as a template model for this large receptor family.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2583103/" 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/PMC2583103/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Cherezov, Vadim -- Rosenbaum, Daniel M -- Hanson, Michael A -- Rasmussen, Soren G F -- Thian, Foon Sun -- Kobilka, Tong Sun -- Choi, Hee-Jung -- Kuhn, Peter -- Weis, William I -- Kobilka, Brian K -- Stevens, Raymond C -- F32 GM082028/GM/NIGMS NIH HHS/ -- GM075915/GM/NIGMS NIH HHS/ -- NS028471/NS/NINDS NIH HHS/ -- P50 GM062411/GM/NIGMS NIH HHS/ -- P50 GM073197/GM/NIGMS NIH HHS/ -- P50 GM073197-04/GM/NIGMS NIH HHS/ -- R01 GM056169/GM/NIGMS NIH HHS/ -- R01 GM089857/GM/NIGMS NIH HHS/ -- R21 GM075811/GM/NIGMS NIH HHS/ -- U54 GM074961/GM/NIGMS NIH HHS/ -- U54 GM074961-030001/GM/NIGMS NIH HHS/ -- Y1-CO-1020/CO/NCI NIH HHS/ -- Y1-GM-1104/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2007 Nov 23;318(5854):1258-65.
