    Three-dimensional structure of recombinant human interferon-gamma (1991)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1991-05-03
    Beschreibung: The x-ray crystal structure of recombinant human interferon-gamma has been determined with the use of multiple-isomorphous-replacement techniques. Interferon-gamma, which is dimeric in solution, crystallizes with two dimers related by a noncrystallographic twofold axis in the asymmetric unit. The protein is primarily alpha helical, with six helices in each subunit that comprise approximately 62 percent of the structure; there is no beta sheet. The dimeric structure of human interferon-gamma is stabilized by the intertwining of helices across the subunit interface with multiple intersubunit interactions.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Ealick, S E -- Cook, W J -- Vijay-Kumar, S -- Carson, M -- Nagabhushan, T L -- Trotta, P P -- Bugg, C E -- CA-13148/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 1991 May 3;252(5006):698-702.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Pharmacology, University of Alabama, Birmingham 35294.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/1902591" target="_blank"〉PubMed〈/a〉

    Binding of the Wilms' tumor locus zinc finger protein to the EGR-1 consensus sequence (1990)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1990-11-30
    Beschreibung: The Wilms' tumor locus (WTL) at 11p13 contains a gene that encodes a zinc finger-containing protein that has characteristics of a DNA-binding protein. However, binding of this protein to DNA in a sequence-specific manner has not been demonstrated. A synthetic gene was constructed that contained the zinc finger region, and the protein was expressed in Escherichia coli. The recombinant protein was used to identify a specific DNA binding site from a pool of degenerate oligonucleotides. The binding sites obtained were similar to the sequence recognized by the early growth response-1 (EGR-1) gene product, a zinc finger-containing protein that is induced by mitogenic stimuli. A mutation in the zinc finger region of the protein originally identified in a Wilms' tumor patient abolished its DNA-binding activity. These results suggest that the WTL protein may act at the DNA binding site of a growth factor-inducible gene and that loss of DNA-binding activity contributes to the tumorigenic process.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Rauscher, F J 3rd -- Morris, J F -- Tournay, O E -- Cook, D M -- Curran, T -- CA0917-15/CA/NCI NIH HHS/ -- CA10817/CA/NCI NIH HHS/ -- CA23413/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 1990 Nov 30;250(4985):1259-62.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Wistar Institute, Philadelphia, PA 19104.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2244209" target="_blank"〉PubMed〈/a〉

    Transcriptional repression mediated by the WT1 Wilms tumor gene product (1991)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1991-10-07
    Beschreibung: The wt1 gene, a putative tumor suppressor gene located at the Wilms tumor (WT) locus on chromosome 11p13, encodes a zinc finger-containing protein that binds to the same DNA sequence as EGR-1, a mitogen-inducible immediate-early gene product that activates transcription. The transcriptional regulatory potential of WT1 has not been demonstrated. In transient transfection assays, the WT1 protein functioned as a repressor of transcription when bound to the EGR-1 site. The repression function was mapped to the glutamine- and proline-rich NH2-terminus of WT1; fusion of this domain to the zinc finger region of EGR-1 converted EGR-1 into a transcriptional repressor.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Madden, S L -- Cook, D M -- Morris, J F -- Gashler, A -- Sukhatme, V P -- Rauscher, F J 3rd -- CA-0917-15/CA/NCI NIH HHS/ -- CA-23413/CA/NCI NIH HHS/ -- CA-52009/CA/NCI NIH HHS/ -- etc. -- New York, N.Y. -- Science. 1991 Sep 27;253(5027):1550-3.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Wistar Institute of Anatomy and Biology, Philadelphia, PA 19104.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/1654597" target="_blank"〉PubMed〈/a〉
