    Exploiting the basis of proline recognition by SH3 and WW domains: design of N-substituted inhibitors (1998)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1998-12-16
    Description: Src homology 3 (SH3) and WW protein interaction domains bind specific proline-rich sequences. However, instead of recognizing critical prolines on the basis of side chain shape or rigidity, these domains broadly accepted amide N-substituted residues. Proline is apparently specifically selected in vivo, despite low complementarity, because it is the only endogenous N-substituted amino acid. This discriminatory mechanism explains how these domains achieve specific but low-affinity recognition, a property that is necessary for transient signaling interactions. The mechanism can be exploited: screening a series of ligands in which key prolines were replaced by nonnatural N-substituted residues yielded a ligand that selectively bound the Grb2 SH3 domain with 100 times greater affinity.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Nguyen, J T -- Turck, C W -- Cohen, F E -- Zuckermann, R N -- Lim, W A -- New York, N.Y. -- Science. 1998 Dec 11;282(5396):2088-92.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Cellular and Molecular Pharmacology, University of California, San Francisco, CA 94143, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/9851931" target="_blank"〉PubMed〈/a〉

    Synthetic mammalian prions (2004)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2004-08-03
    Description: Recombinant mouse prion protein (recMoPrP) produced in Escherichia coli was polymerized into amyloid fibrils that represent a subset of beta sheet-rich structures. Fibrils consisting of recMoPrP(89-230) were inoculated intracerebrally into transgenic (Tg) mice expressing MoPrP(89-231). The mice developed neurologic dysfunction between 380 and 660 days after inoculation. Brain extracts showed protease-resistant PrP by Western blotting; these extracts transmitted disease to wild-type FVB mice and Tg mice overexpressing PrP, with incubation times of 150 and 90 days, respectively. Neuropathological findings suggest that a novel prion strain was created. Our results provide compelling evidence that prions are infectious proteins.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Legname, Giuseppe -- Baskakov, Ilia V -- Nguyen, Hoang-Oanh B -- Riesner, Detlev -- Cohen, Fred E -- DeArmond, Stephen J -- Prusiner, Stanley B -- AG02132/AG/NIA NIH HHS/ -- AG021601/AG/NIA NIH HHS/ -- AG10770/AG/NIA NIH HHS/ -- New York, N.Y. -- Science. 2004 Jul 30;305(5684):673-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Institute for Neurodegenerative Diseases, University of California, San Francisco, CA 94143, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/15286374" target="_blank"〉PubMed〈/a〉

    Structure-activity studies of interleukin-2 (1986)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1986-10-17
    Description: The critical role of interleukin-2 (IL-2) in immune response heightens the need to know its structure in order to understand its activity. New computer-assisted predictive methods for the assignment of secondary structure together with a method to predict the tertiary structure of a protein from data on its primary sequence and secondary structure were applied to IL-2. This method generated four topological families of structures, of which the most plausible is a right-handed fourfold alpha-helical bundle. Members of this family were shown to be compatible with existing structural data on disulfide bridges and monoclonal antibody binding for IL-2. Experimental estimates of secondary structure from circular dichroism and site-directed mutagenesis data support the model. A region likely to be important in IL-2 binding to its receptor was identified as residues Leu36, Met38, Leu40, Phe42, Phe44, and Met46.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Cohen, F E -- Kosen, P A -- Kuntz, I D -- Epstein, L B -- Ciardelli, T L -- Smith, K A -- CA27903/CA/NCI NIH HHS/ -- GM34197/GM/NIGMS NIH HHS/ -- MOJ JD17001/PHS HHS/ -- etc. -- New York, N.Y. -- Science. 1986 Oct 17;234(4774):349-52.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3489989" target="_blank"〉PubMed〈/a〉

    Notes: [Auszug] Baldwin3 and Karplus and Weaver4'5 have considered the experimental and theoretical evidence as to the probable rate-limiting step during (fast) folding. They agree that the formation of a local structure by a random search is unlikely to act as a nucleus for subsequent rapid folding. Instead, they ...
