    Global efforts in structural genomics (2001)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2001-10-06
    Description: A worldwide initiative in structural genomics aims to capitalize on the recent successes of the genome projects. Substantial new investments in structural genomics in the past 2 years indicate the high level of support for these international efforts. Already, enormous progress has been made on high-throughput methodologies and technologies that will speed up macromolecular structure determinations. Recent international meetings have resulted in the formation of an International Structural Genomics Organization to formulate policy and foster cooperation between the public and private efforts.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Stevens, R C -- Yokoyama, S -- Wilson, I A -- P50 GM62411/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2001 Oct 5;294(5540):89-92.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Joint Center for Structural Genomics, 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/11588249" target="_blank"〉PubMed〈/a〉

    Role of the ENTH domain in phosphatidylinositol-4,5-bisphosphate binding and endocytosis (2001)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2001-02-13
    Description: Endocytic proteins such as epsin, AP180, and Hip1R (Sla2p) share a conserved modular region termed the epsin NH2-terminal homology (ENTH) domain, which plays a crucial role in clathrin-mediated endocytosis through an unknown target. Here, we demonstrate a strong affinity of the ENTH domain for phosphatidylinositol-4,5-bisphosphate [PtdIns(4,5)P2]. With nuclear magnetic resonance analysis of the epsin ENTH domain, we determined that a cleft formed with positively charged residues contributed to phosphoinositide binding. Overexpression of a mutant, epsin Lys76 --〉 Ala76, with an ENTH domain defective in phosphoinositide binding, blocked epidermal growth factor internalization in COS-7 cells. Thus, interaction between the ENTH domain and PtdIns(4,5)P2 is essential for endocytosis mediated by clathrin-coated pits.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Itoh, T -- Koshiba, S -- Kigawa, T -- Kikuchi, A -- Yokoyama, S -- Takenawa, T -- New York, N.Y. -- Science. 2001 Feb 9;291(5506):1047-51.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biochemistry, Institute of Medical Science, University of Tokyo, 4-6-1 Shirokanedai, Minato-ku, Tokyo 108-8639, Japan.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/11161217" target="_blank"〉PubMed〈/a〉

    Vital involvement of a natural killer cell activation receptor in resistance to viral infection (2001)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2001-05-08
    Description: Natural killer (NK) cells are lymphocytes that can be distinguished from T and B cells through their involvement in innate immunity and their lack of rearranged antigen receptors. Although NK cells and their receptors were initially characterized in terms of tumor killing in vitro, we have determined that the NK cell activation receptor, Ly-49H, is critically involved in resistance to murine cytomegalovirus in vivo. Ly-49H requires an immunoreceptor tyrosine-based activation motif (ITAM)-containing transmembrane molecule for expression and signal transduction. Thus, NK cells use receptors functionally resembling ITAM-coupled T and B cell antigen receptors to provide vital innate host defense.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Brown, M G -- Dokun, A O -- Heusel, J W -- Smith, H R -- Beckman, D L -- Blattenberger, E A -- Dubbelde, C E -- Stone, L R -- Scalzo, A A -- Yokoyama, W M -- New York, N.Y. -- Science. 2001 May 4;292(5518):934-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Howard Hughes Medical Institute, Rheumatology Division, Washington University School of Medicine, St. Louis, MO 63110, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/11340207" target="_blank"〉PubMed〈/a〉

    Reversal of left-right asymmetry: a situs inversus mutation (1993)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1993-04-30
    Description: A recessive mutation was identified in a family of transgenic mice that resulted in a reversal of left-right polarity (situs inversus) in 100 percent of the homozygous transgenic mice tested. Sequences that flanked the transgenic integration site were cloned and mapped to mouse chromosome 4, between the Tsha and Hxb loci. During early embryonic development, the direction of postimplantation turning, one of the earliest manifestations of left-right asymmetry, was reversed in homozygous transgenic embryos. This insertional mutation identifies a gene that controls embryonic turning and visceral left-right polarity.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Yokoyama, T -- Copeland, N G -- Jenkins, N A -- Montgomery, C A -- Elder, F F -- Overbeek, P A -- HD25340/HD/NICHD NIH HHS/ -- N01-CO-74101/CO/NCI NIH HHS/ -- New York, N.Y. -- Science. 1993 Apr 30;260(5108):679-82.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Cell Biology, Baylor College of Medicine, Houston, TX 77030.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8480178" target="_blank"〉PubMed〈/a〉

    Altered growth of human colon cancer cell lines disrupted at activated Ki-ras (1993)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1993-04-02
    Description: Point mutations that activate the Ki-ras proto-oncogene are presented in about 50 percent of human colorectal tumors. To study the functional significance of these mutations, the activated Ki-ras genes in two human colon carcinoma cell lines, DLD-1 and HCT 116, were disrupted by homologous recombination. Compared with parental cells, cells disrupted at the activated Ki-ras gene were morphologically altered, lost the capacity for anchorage-independent growth, grew more slowly both in vitro and in nude mice, and showed reduced expression of c-myc. Thus, the activated Ki-ras gene plays a key role in colorectal tumorigenesis through altered cell differentiation and cell growth.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Shirasawa, S -- Furuse, M -- Yokoyama, N -- Sasazuki, T -- New York, N.Y. -- Science. 1993 Apr 2;260(5104):85-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Genetics, Kyushu University, Fukuoka, Japan.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8465203" target="_blank"〉PubMed〈/a〉
