    Description: The interaction of the T cell receptor for antigen (TCR) with its antigen-major histocompatibility complex ligand is difficult to study because both are cell surface multimers. The TCR consists of two chains (alpha and beta) that are complexed to the five or more nonpolymorphic CD3 polypeptides. A soluble form of the TCR was engineered by replacing the carboxyl termini of alpha and beta with signal sequences from lipid-linked proteins, making them susceptible to enzymatic cleavage. In this manner, TCR heterodimers can be expressed independently of the CD3 polypeptides and in significant quantities (0.5 milligram per week). This technique seems generalizable to biochemical and structural studies of many other cell surface molecules as well.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lin, A Y -- Devaux, B -- Green, A -- Sagerstrom, C -- Elliott, J F -- Davis, M M -- New York, N.Y. -- Science. 1990 Aug 10;249(4969):677-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Howard Hughes Medical Institute, Stanford University School of Medicine, CA 94305-5402.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/1696397" target="_blank"〉PubMed〈/a〉

    Description: Cold-sensitive mutations in the SPB genes (spb1-spb7) of Saccharomyces cerevisiae suppress the inhibition of translation initiation resulting from deletion of the poly(A)-binding protein gene (PAB1). The SPB4 protein belongs to a family of adenosine triphosphate (ATP)-dependent RNA helicases. The aberrant production of 25S ribosomal RNA (rRNA) occurring in spb4-1 mutants or the deletion of SPB2 (RPL46) permits the deletion of PAB1. These data suggest that mutations affecting different steps of 60S subunit formation can allow PAB-independent translation, and they indicate that further characterization of the spb mutations could lend insight into the biogenesis of the ribosome.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Sachs, A B -- Davis, R W -- R37 GM 21891/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1990 Mar 2;247(4946):1077-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biochemistry, Stanford Medical Center, CA 94305.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2408148" target="_blank"〉PubMed〈/a〉

    Description: Tumor necrosis factor alpha and beta (TNF-alpha and TNF-beta) bind surface receptors on a variety of cell types to mediate a wide range of immunological responses, inflammatory reactions, and anti-tumor effects. A cDNA clone encoding an integral membrane protein of 461 amino acids was isolated from a human lung fibroblast library by direct expression screening with radiolabeled TNF-alpha. The encoded receptor was also able to bind TNF-beta. The predicted cysteine-rich extracellular domain has extensive sequence similarity with five proteins, including nerve growth factor receptor and a transcriptionally active open reading frame from Shope fibroma virus, and thus defines a family of receptors.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Smith, C A -- Davis, T -- Anderson, D -- Solam, L -- Beckmann, M P -- Jerzy, R -- Dower, S K -- Cosman, D -- Goodwin, R G -- New York, N.Y. -- Science. 1990 May 25;248(4958):1019-23.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Immunex Corporation, Seattle, WA 98101.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2160731" target="_blank"〉PubMed〈/a〉

    Description: Schizophrenia is a devastating neurodevelopmental disorder whose genetic influences remain elusive. We hypothesize that individually rare structural variants contribute to the illness. Microdeletions and microduplications 〉100 kilobases were identified by microarray comparative genomic hybridization of genomic DNA from 150 individuals with schizophrenia and 268 ancestry-matched controls. All variants were validated by high-resolution platforms. Novel deletions and duplications of genes were present in 5% of controls versus 15% of cases and 20% of young-onset cases, both highly significant differences. The association was independently replicated in patients with childhood-onset schizophrenia as compared with their parents. Mutations in cases disrupted genes disproportionately from signaling networks controlling neurodevelopment, including neuregulin and glutamate pathways. These results suggest that multiple, individually rare mutations altering genes in neurodevelopmental pathways contribute to schizophrenia.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Walsh, Tom -- McClellan, Jon M -- McCarthy, Shane E -- Addington, Anjene M -- Pierce, Sarah B -- Cooper, Greg M -- Nord, Alex S -- Kusenda, Mary -- Malhotra, Dheeraj -- Bhandari, Abhishek -- Stray, Sunday M -- Rippey, Caitlin F -- Roccanova, Patricia -- Makarov, Vlad -- Lakshmi, B -- Findling, Robert L -- Sikich, Linmarie -- Stromberg, Thomas -- Merriman, Barry -- Gogtay, Nitin -- Butler, Philip -- Eckstrand, Kristen -- Noory, Laila -- Gochman, Peter -- Long, Robert -- Chen, Zugen -- Davis, Sean -- Baker, Carl -- Eichler, Evan E -- Meltzer, Paul S -- Nelson, Stanley F -- Singleton, Andrew B -- Lee, Ming K -- Rapoport, Judith L -- King, Mary-Claire -- Sebat, Jonathan -- HD043569/HD/NICHD NIH HHS/ -- M01 RR000046/RR/NCRR NIH HHS/ -- MH061355/MH/NIMH NIH HHS/ -- MH061464/MH/NIMH NIH HHS/ -- MH061528/MH/NIMH NIH HHS/ -- NS052108/NS/NINDS NIH HHS/ -- R01 HD043569/HD/NICHD NIH HHS/ -- RR000046/RR/NCRR NIH HHS/ -- RR025014/RR/NCRR NIH HHS/ -- U01 MH061355/MH/NIMH NIH HHS/ -- U01 MH061464/MH/NIMH NIH HHS/ -- U01 MH061528/MH/NIMH NIH HHS/ -- U24 NS052108/NS/NINDS NIH HHS/ -- UL1 RR025014/RR/NCRR NIH HHS/ -- Howard Hughes Medical Institute/ -- Intramural NIH HHS/ -- New York, N.Y. -- Science. 2008 Apr 25;320(5875):539-43. doi: 10.1126/science.1155174.

    Description: Diffuse large B cell lymphoma (DLBCL) is the most common form of non-Hodgkin's lymphoma. In the least curable (ABC) subtype of DLBCL, survival of the malignant cells is dependent on constitutive activation of the nuclear factor-kappaB (NF-kappaB) signaling pathway. In normal B cells, antigen receptor-induced NF-kappaB activation requires CARD11, a cytoplasmic scaffolding protein. To determine whether CARD11 contributes to tumorigenesis, we sequenced the CARD11 gene in human DLBCL tumors. We detected missense mutations in 7 of 73 ABC DLBCL biopsies (9.6%), all within exons encoding the coiled-coil domain. Experimental introduction of CARD11 coiled-coil domain mutants into lymphoma cell lines resulted in constitutive NF-kappaB activation and enhanced NF-kappaB activity upon antigen receptor stimulation. These results demonstrate that CARD11 is a bona fide oncogenein DLBCL, providing a genetic rationale for the development of pharmacological inhibitors of the CARD11 pathway for DLBCL therapy.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lenz, Georg -- Davis, R Eric -- Ngo, Vu N -- Lam, Lloyd -- George, Thaddeus C -- Wright, George W -- Dave, Sandeep S -- Zhao, Hong -- Xu, Weihong -- Rosenwald, Andreas -- Ott, German -- Muller-Hermelink, Hans Konrad -- Gascoyne, Randy D -- Connors, Joseph M -- Rimsza, Lisa M -- Campo, Elias -- Jaffe, Elaine S -- Delabie, Jan -- Smeland, Erlend B -- Fisher, Richard I -- Chan, Wing C -- Staudt, Louis M -- UO1-CA84967/CA/NCI NIH HHS/ -- Intramural NIH HHS/ -- New York, N.Y. -- Science. 2008 Mar 21;319(5870):1676-9. doi: 10.1126/science.1153629.
