    Beschreibung: 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〉

    Beschreibung: The two mouse genes, En-1 and En-2, that are homologs of the Drosophila segmentation gene engrailed, show overlapping spatially restricted patterns of expression in the neural tube during embryogenesis, suggestive of a role in regional specification. Mice homozygous for a targeted mutation that deletes the homeobox were viable and showed no obvious defects in embryonic development. This may be due to functional redundancy of En-2 and the related En-1 gene product during embryogenesis. Consistent with this hypothesis, the mutant mice showed abnormal foliation in the adult cerebellum, where En-2, and not En-1, is normally expressed.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Joyner, A L -- Herrup, K -- Auerbach, B A -- Davis, C A -- Rossant, J -- HD25334/HD/NICHD NIH HHS/ -- NS18381/NS/NINDS NIH HHS/ -- NS20591/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 1991 Mar 8;251(4998):1239-43.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Samuel Lunenfeld Research Institute, Mount Sinai Hospital, Toronto, Ontario, Canada.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/1672471" target="_blank"〉PubMed〈/a〉

    Beschreibung: Although neurotrophic factors were originally isolated on the basis of their ability to support the survival of neurons, these molecules are now thought to influence many aspects of the development and maintenance of the nervous system. Identifying the receptors for these neurotrophic factors should aid in identifying the cells on which these factors act and in understanding their precise mechanisms of action. A "tagged-ligand panning" procedure was used to clone a receptor for ciliary neurotrophic factor (CNTF). This receptor is expressed exclusively within the nervous system and skeletal muscle. The CNTF receptor has a structure unrelated to the receptors utilized by the nerve growth factor family of neurotrophic molecules, but instead is most homologous to the receptor for a cytokine, interleukin-6. This similarity suggestes that the CNTF receptor, like the interleukin-6 receptor, requires a second, signal-transducing component. In contrast to all known receptors, the CNTF receptor is anchored to cell membranes by a glycosyl-phosphatidylinositol linkage.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Davis, S -- Aldrich, T H -- Valenzuela, D M -- Wong, V V -- Furth, M E -- Squinto, S P -- Yancopoulos, G D -- New York, N.Y. -- Science. 1991 Jul 5;253(5015):59-63.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Regeneron Pharmaceuticals, Inc., Tarrytown, NY 10591.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/1648265" target="_blank"〉PubMed〈/a〉

    Beschreibung: The interaction of antigen-specific T cell receptors (TCRs) with their ligands, peptides bound to molecules of the major histocompatibility complex (MHC), is central to most immune responses, yet little is known about its chemical characteristics. The binding to T cells of a labeled monoclonal antibody to the TCR was inhibited by soluble class II MHC heterodimers complexed to different peptides. Inhibition was both peptide- and TCR-specific and of low affinity, with a KD = 4 x 10(-5) to 6 x 10(-5) M, orders of magnitude weaker than comparable antibody-antigen interactions. This finding is consistent with the scanning nature of T cell recognition and suggests that antigen-independent adhesion precedes TCR engagement.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Matsui, K -- Boniface, J J -- Reay, P A -- Schild, H -- Fazekas de St Groth, B -- Davis, M M -- AI19512/AI/NIAID NIH HHS/ -- New York, N.Y. -- Science. 1991 Dec 20;254(5039):1788-91.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Howard Hughes Medical Institute, Stanford, CA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/1763329" target="_blank"〉PubMed〈/a〉

    Beschreibung: Class II major histocompatibility complexes bind peptides in an endosome-like compartment. When the class II null cell line 721.174 was transfected with class II DR3 genes, DR molecules were produced in normal amounts. However, the DR molecules were abnormally conformed and unstable because deletion of an antigen-processing gene had impaired intracellular formation of most class II-peptide complexes. Yet, 70 percent of the DR molecules still bore peptides, 80 percent of which were 21- to 24-amino acid fragments of the class II-associated invariant chain. These peptides were rare on DR3 from control cells. Thus, a defect in the main antigen-processing pathway revealed a process in which DR molecules bind long peptides derived from proteins present in the same compartment.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Sette, A -- Ceman, S -- Kubo, R T -- Sakaguchi, K -- Appella, E -- Hunt, D F -- Davis, T A -- Michel, H -- Shabanowitz, J -- Rudersdorf, R -- AI15486/AI/NIAID NIH HHS/ -- AI18634/AI/NIAID NIH HHS/ -- GM37537/GM/NIGMS NIH HHS/ -- etc. -- New York, N.Y. -- Science. 1992 Dec 11;258(5089):1801-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Laboratory of Genetics, University of Wisconsin, Madison 53706.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/1465617" target="_blank"〉PubMed〈/a〉

    Beschreibung: The basic helix-loop-helix (bHLH) protein MyoD is a transcription factor that is important for the induction of the myogenic phenotype. The DNA binding basic region (13 amino acids) is necessary for recognition of the consensus MyoD binding site, for transcriptional activation, and for conversion of fibroblasts to muscle. In contrast, the non-tissue-specific bHLH protein E12 can bind to the MyoD binding site but does not induce myogenesis. Here, it is shown that only two amino acids in the MyoD basic region and a single amino acid from the junction, which separates the basic region and helix 1, are sufficient for myogenic specificity when substituted into the corresponding region of E12. These findings suggest that the recognition of particular determinants in the basic region is required for conversion of fibroblasts to muscle.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Davis, R L -- Weintraub, H -- New York, N.Y. -- Science. 1992 May 15;256(5059):1027-30.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Howard Hughes Medical Institute Laboratory, Fred Hutchinson Cancer Research Center, Seattle, WA 98104.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/1317057" target="_blank"〉PubMed〈/a〉

    Beschreibung: Immunity-related p47 guanosine triphosphatases (IRG) play a role in defense against intracellular pathogens. We found that the murine Irgm1 (LRG-47) guanosine triphosphatase induced autophagy and generated large autolysosomal organelles as a mechanism for the elimination of intracellular Mycobacterium tuberculosis. We also identified a function for a human IRG protein in the control of intracellular pathogens and report that the human Irgm1 ortholog, IRGM, plays a role in autophagy and in the reduction of intracellular bacillary load.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Singh, Sudha B -- Davis, Alexander S -- Taylor, Gregory A -- Deretic, Vojo -- AI42999/AI/NIAID NIH HHS/ -- AI45148/AI/NIAID NIH HHS/ -- AI57831/AI/NIAID NIH HHS/ -- R01 AI057831/AI/NIAID NIH HHS/ -- T32 AI007538/AI/NIAID NIH HHS/ -- New York, N.Y. -- Science. 2006 Sep 8;313(5792):1438-41.

    Beschreibung: The ciliary neurotrophic factor (CNTF) receptor complex is shown here to include the CNTF binding protein (CNTFR alpha) as well as the components of the leukemia inhibitory factor (LIF) receptor, LIFR beta (the LIF binding protein) and gp130 [the signal transducer of interleukin-6 (IL-6)]. Thus, the conversion of a bipartite LIF receptor into a tripartite CNTF receptor apparently occurs by the addition of the specificity-conferring element CNTFR alpha. Both CNTF and LIF trigger the association of initially separate receptor components, which in turn results in tyrosine phosphorylation of receptor subunits. Unlike the IL-6 receptor complex in which homodimerization of gp130 appears to be critical for signal initiation, signaling by the CNTF and LIF receptor complexes depends on the heterodimerization of gp130 with LIFR beta. Ligand-induced dimerization of signal-transducing receptor components, also seen with receptor tyrosine kinases, may provide a general mechanism for the transmission of a signal across the cell membrane.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Davis, S -- Aldrich, T H -- Stahl, N -- Pan, L -- Taga, T -- Kishimoto, T -- Ip, N Y -- Yancopoulos, G D -- New York, N.Y. -- Science. 1993 Jun 18;260(5115):1805-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Regeneron Pharmaceuticals, Inc., Tarrytown, NY 10591.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8390097" target="_blank"〉PubMed〈/a〉

    Beschreibung: The EPH-related transmembrane tyrosine kinases constitute the largest known family of receptor-like tyrosine kinases, with many members displaying specific patterns of expression in the developing and adult nervous system. A family of cell surface-bound ligands exhibiting distinct, but overlapping, specificities for these EPH-related kinases was identified. These ligands were unable to act as conventional soluble factors. However, they did function when presented in membrane-bound form, suggesting that they require direct cell-to-cell contact to activate their receptors. Membrane attachment may serve to facilitate ligand dimerization or aggregation, because antibody-mediated clustering activated previously inactive soluble forms of these ligands.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Davis, S -- Gale, N W -- Aldrich, T H -- Maisonpierre, P C -- Lhotak, V -- Pawson, T -- Goldfarb, M -- Yancopoulos, G D -- New York, N.Y. -- Science. 1994 Nov 4;266(5186):816-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Regeneron Pharmaceuticals, Tarrytown, NY 10591.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7973638" target="_blank"〉PubMed〈/a〉

    Beschreibung: A recently defined family of cytokines, consisting of ciliary neurotrophic factor (CNTF), leukemia inhibitory factor (LIF), oncostatin M (OSM), and interleukin-6 (IL-6), utilize the Jak-Tyk family of cytoplasmic tyrosine kinases. The beta receptor components for this cytokine family, gp130 and LIF receptor beta, constitutively associate with Jak-Tyk kinases. Activation of these kinases occurs as a result of ligand-induced dimerization of the receptor beta components. Unlike other cytokine receptors studied to date, the receptors for the CNTF cytokine family utilize all known members of the Jak-Tyk family, but induce distinct patterns of Jak-Tyk phosphorylation in different cell lines.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Stahl, N -- Boulton, T G -- Farruggella, T -- Ip, N Y -- Davis, S -- Witthuhn, B A -- Quelle, F W -- Silvennoinen, O -- Barbieri, G -- Pellegrini, S -- P30 CA21765/CA/NCI NIH HHS/ -- R01 DK42932/DK/NIDDK NIH HHS/ -- New York, N.Y. -- Science. 1994 Jan 7;263(5143):92-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Regeneron Pharmaceuticals, Inc., Tarrytown, NY 10591.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8272873" target="_blank"〉PubMed〈/a〉
