    Structure of an extracellular gp130 cytokine receptor signaling complex (2001)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 2001-03-17
    Beschreibung: The activation of gp130, a shared signal-transducing receptor for a family of cytokines, is initiated by recognition of ligand followed by oligomerization into a higher order signaling complex. Kaposi's sarcoma-associated herpesvirus encodes a functional homolog of human interleukin-6 (IL-6) that activates human gp130. In the 2.4 angstrom crystal structure of the extracellular signaling assembly between viral IL-6 and human gp130, two complexes are cross-linked into a tetramer through direct interactions between the immunoglobulin domain of gp130 and site III of viral IL-6, which is necessary for receptor activation. Unlike human IL-6 (which uses many hydrophilic residues), the viral cytokine largely uses hydrophobic amino acids to contact gp130, which enhances the complementarity of the viral IL-6-gp130 binding interfaces. The cross-reactivity of gp130 is apparently due to a chemical plasticity evident in the amphipathic gp130 cytokine-binding sites.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Chow , D -- He , X -- Snow, A L -- Rose-John, S -- Garcia, K C -- R01-AI-48540-01/AI/NIAID NIH HHS/ -- New York, N.Y. -- Science. 2001 Mar 16;291(5511):2150-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Microbiology and Immunology, Stanford University School of Medicine, Fairchild D319, 299 Campus Drive, Stanford, CA 94305, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/11251120" target="_blank"〉PubMed〈/a〉

    Location of a major susceptibility locus for familial schizophrenia on chromosome 1q21-q22 (2000)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 2000-04-28
    Beschreibung: Schizophrenia is a complex disorder, and there is substantial evidence supporting a genetic etiology. Despite this, prior attempts to localize susceptibility loci have produced predominantly suggestive findings. A genome-wide scan for schizophrenia susceptibility loci in 22 extended families with high rates of schizophrenia provided highly significant evidence of linkage to chromosome 1 (1q21-q22), with a maximum heterogeneity logarithm of the likelihood of linkage (lod) score of 6.50. This linkage result should provide sufficient power to allow the positional cloning of the underlying susceptibility gene.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3787922/" 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/PMC3787922/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Brzustowicz, L M -- Hodgkinson, K A -- Chow, E W -- Honer, W G -- Bassett, A S -- 53216/Canadian Institutes of Health Research/Canada -- K08 MH01392/MH/NIMH NIH HHS/ -- N01-HG-65403/HG/NHGRI NIH HHS/ -- New York, N.Y. -- Science. 2000 Apr 28;288(5466):678-82.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Center for Molecular and Behavioral Neuroscience, Rutgers University, Newark, NJ 07102, USA. brzustowicz@axon.rutgers.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/10784452" target="_blank"〉PubMed〈/a〉

    Allosteric activation of a spring-loaded natriuretic peptide receptor dimer by hormone (2001)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 2001-09-05
    Beschreibung: Natriuretic peptides (NPs) are vasoactive cyclic-peptide hormones important in blood pressure regulation through interaction with natriuretic cell-surface receptors. We report the hormone-binding thermodynamics and crystal structures at 2.9 and 2.0 angstroms, respectively, of the extracellular domain of the unliganded human NP receptor (NPR-C) and its complex with CNP, a 22-amino acid NP. A single CNP molecule is bound in the interface of an NPR-C dimer, resulting in asymmetric interactions between the hormone and the symmetrically related receptors. Hormone binding induces a 20 angstrom closure between the membrane-proximal domains of the dimer. In each monomer, the opening of an interdomain cleft, which is tethered together by a linker peptide acting as a molecular spring, is likely a conserved allosteric trigger for intracellular signaling by the natriuretic receptor family.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉He Xl -- Chow Dc -- Martick, M M -- Garcia, K C -- New York, N.Y. -- Science. 2001 Aug 31;293(5535):1657-62.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Departments of Microbiology and Immunology and Structural Biology, Stanford University School of Medicine, Fairchild D319, 299 Campus Drive, Stanford, CA 93405-5124, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/11533490" target="_blank"〉PubMed〈/a〉

    Hexameric structure and assembly of the interleukin-6/IL-6 alpha-receptor/gp130 complex (2003)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 2003-06-28
    Beschreibung: Interleukin-6 (IL-6) is an immunoregulatory cytokine that activates a cell-surface signaling assembly composed of IL-6, the IL-6 alpha-receptor (IL-6Ralpha), and the shared signaling receptor gp130. The 3.65 angstrom-resolution structure of the extracellular signaling complex reveals a hexameric, interlocking assembly mediated by a total of 10 symmetry-related, thermodynamically coupled interfaces. Assembly of the hexameric complex occurs sequentially: IL-6 is first engaged by IL-6Ralpha and then presented to gp130in the proper geometry to facilitate a cooperative transition into the high-affinity, signaling-competent hexamer. The quaternary structures of other IL-6/IL-12 family signaling complexes are likely constructed by means of a similar topological blueprint.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Boulanger, Martin J -- Chow, Dar-chone -- Brevnova, Elena E -- Garcia, K Christopher -- AI51321/AI/NIAID NIH HHS/ -- New York, N.Y. -- Science. 2003 Jun 27;300(5628):2101-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Microbiology and Immunology and Department of Structural Biology, Stanford University School of Medicine, Fairchild D319, 299 Campus Drive, Stanford, CA 94305-5124, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/12829785" target="_blank"〉PubMed〈/a〉
