    A structural framework for deciphering the link between I-Ag7 and autoimmune diabetes (2000)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2000-04-25
    Description: Susceptibility to murine and human insulin-dependent diabetes mellitus correlates strongly with major histocompatibility complex (MHC) class II I-A or HLA-DQ alleles that lack an aspartic acid at position beta57. I-Ag7 lacks this aspartate and is the only class II allele expressed by the nonobese diabetic mouse. The crystal structure of I-Ag7 was determined at 2.6 angstrom resolution as a complex with a high-affinity peptide from the autoantigen glutamic acid decarboxylase (GAD) 65. I-Ag7 has a substantially wider peptide-binding groove around beta57, which accounts for distinct peptide preferences compared with other MHC class II alleles. Loss of Asp(beta57) leads to an oxyanion hole in I-Ag7 that can be filled by peptide carboxyl residues or, perhaps, through interaction with the T cell receptor.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Corper, A L -- Stratmann, T -- Apostolopoulos, V -- Scott, C A -- Garcia, K C -- Kang, A S -- Wilson, I A -- Teyton, L -- CA58896/CA/NCI NIH HHS/ -- DK55037/DK/NIDDK NIH HHS/ -- New York, N.Y. -- Science. 2000 Apr 21;288(5465):505-11.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Molecular Biology and Skaggs Institute for Chemical Biology, The 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/10775108" target="_blank"〉PubMed〈/a〉

    Structure of an extracellular gp130 cytokine receptor signaling complex (2001)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2001-03-17
    Description: 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〉

    Allosteric activation of a spring-loaded natriuretic peptide receptor dimer by hormone (2001)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2001-09-05
    Description: 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
    Publication Date: 2003-06-28
    Description: 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〉

    Structure of nerve growth factor complexed with the shared neurotrophin receptor p75 (2004)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2004-05-08
    Description: Neurotrophins are secreted growth factors critical for the development and maintenance of the vertebrate nervous system. Neurotrophins activate two types of cell surface receptors, the Trk receptor tyrosine kinases and the shared p75 neurotrophin receptor. We have determined the 2.4 A crystal structure of the prototypic neurotrophin, nerve growth factor (NGF), complexed with the extracellular domain of p75. Surprisingly, the complex is composed of an NGF homodimer asymmetrically bound to a single p75. p75 binds along the homodimeric interface of NGF, which disables NGF's symmetry-related second p75 binding site through an allosteric conformational change. Thus, neurotrophin signaling through p75 may occur by disassembly of p75 dimers and assembly of asymmetric 2:1 neurotrophin/p75 complexes, which could potentially engage a Trk receptor to form a trimolecular signaling complex.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉He, Xiao-Lin -- Garcia, K Christopher -- New York, N.Y. -- Science. 2004 May 7;304(5672):870-5.〈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 94305-5124, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/15131306" target="_blank"〉PubMed〈/a〉
