    Stabilization of interleukin-2 mRNA by the c-Jun NH2-terminal kinase pathway (1998)
    American Association for the Advancement of Science (AAAS)

    Beschreibung: Signaling pathways that stabilize interleukin-2 (IL-2) messenger RNA (mRNA) in activated T cells were examined. IL-2 mRNA contains at least two cis elements that mediated its stabilization in response to different signals, including activation of c-Jun amino-terminal kinase (JNK). This response was mediated through a cis element encompassing the 5' untranslated region (UTR) and the beginning of the coding region. IL-2 transcripts lacking this 5' element no longer responded to JNK activation but were still responsive to other signals generated during T cell activation, which were probably sensed through the 3' UTR. Thus, multiple elements within IL-2 mRNA modulate its stability in a combinatorial manner, and the JNK pathway controls turnover as well as synthesis of IL-2 mRNA.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Chen, C Y -- Del Gatto-Konczak, F -- Wu, Z -- Karin, M -- New York, N.Y. -- Science. 1998 Jun 19;280(5371):1945-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Pharmacology, School of Medicine, University of California, San Diego, La Jolla, CA 92093, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/9632395" target="_blank"〉PubMed〈/a〉

    Active human-yeast chimeric phosphoglycerate kinases engineered by domain interchange (1986)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1986-08-15
    Beschreibung: Phosphoglycerate kinase (PGK) is a monomeric protein composed of two domains of approximately equal size, connected by a hinge. Substrate-induced conformational change results in the closure of the active site cleft, which is situated between these two domains. In a study of the relations between structure and function of this enzyme, two interspecies hybrids were constructed, each composed of one domain from the human enzyme and one domain from the yeast enzyme. Despite a 35% difference in the amino acid composition between human and yeast PGK, catalytic properties of the hybrid enzymes are very similar to those of the parental proteins. This result demonstrates that the evolutionary substitutions within these two distantly related molecules do not significantly affect formation of the active site cleft, mechanism of domain closure, or enzyme activity itself.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Mas, M T -- Chen, C Y -- Hitzeman, R A -- Riggs, A D -- R01 GM31263/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1986 Aug 15;233(4765):788-90.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3526552" target="_blank"〉PubMed〈/a〉
