    Description: Filamentous bacteriophage Pf1 assembles by a membrane-mediated process during which the viral DNA is secreted through the membrane while being encapsulated by the major coat protein. Neutron diffraction studies showed that in the virus most of the coat protein consists of two alpha-helical segments arranged end-to-end with an intervening mobile surface loop. Nuclear magnetic resonance studies of the coat protein in the membrane-bound form have shown that the secondary structure is essentially identical to that in the intact virus. A comparison indicates that during membrane-mediated viral assembly, while the secondary structure of the coat protein is largely conserved, its tertiary structure changes substantially.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Nambudripad, R -- Stark, W -- Opella, S J -- Makowski, L -- New York, N.Y. -- Science. 1991 May 31;252(5010):1305-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Physics, Boston University, MA 02215.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/1925543" target="_blank"〉PubMed〈/a〉

    Description: Interferon-gamma (IFN-gamma) stimulates transcription of specific genes by inducing tyrosine phosphorylation of a 91-kilodalton cytoplasmic protein (termed STAT for signal transducer and activator of transcription). Stat91 was phosphorylated on a single site (Tyr701), and phosphorylation of this site was required for nuclear translocation, DNA binding, and gene activation. Stat84, a differentially spliced product of the same gene that lacks the 38 carboxyl-terminal amino acids of Stat91, did not activate transcription, although it was phosphorylated and translocated to the nucleus and bound DNA. Thus, Stat91 mediates activation of transcription in response to IFN-gamma.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Shuai, K -- Stark, G R -- Kerr, I M -- Darnell, J E Jr -- AI32489-02/AI/NIAID NIH HHS/ -- New York, N.Y. -- Science. 1993 Sep 24;261(5129):1744-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Rockefeller University, Laboratory of Molecular Cell Biology, New York, NY 10021.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7690989" target="_blank"〉PubMed〈/a〉
