    The interaction of Pcf11 and Clp1 is needed for mRNA 3'-end formation and is modulated by amino acids in the ATP-binding site (2012)
    Oxford University Press
    Details
    Publication Date: 2012-02-17
    Description: Polyadenylation of eukaryotic mRNAs contributes to stability, transport and translation, and is catalyzed by a large complex of conserved proteins. The Pcf11 subunit of the yeast CF IA factor functions as a scaffold for the processing machinery during the termination and polyadenylation of transcripts. Its partner, Clp1, is needed for mRNA processing, but its precise molecular role has remained enigmatic. We show that Clp1 interacts with the Cleavage–Polyadenylation Factor (CPF) through its N-terminal and central domains, and thus provides cross-factor connections within the processing complex. Clp1 is known to bind ATP, consistent with the reported RNA kinase activity of human Clp1. However, substitution of conserved amino acids in the ATP-binding site did not affect cell growth, suggesting that the essential function of yeast Clp1 does not involve ATP hydrolysis. Surprisingly, non-viable mutations predicted to displace ATP did not affect ATP binding but disturbed the Clp1–Pcf11 interaction. In support of the importance of this interaction, a mutation in Pcf11 that disrupts the Clp1 contact caused defects in growth, 3'-end processing and transcription termination. These results define Clp1 as a bridge between CF IA and CPF and indicate that the Clp1–Pcf11 interaction is modulated by amino acids in the conserved ATP-binding site of Clp1.

    Dysregulated humoral immunity to nontyphoidal Salmonella in HIV-infected African adults (2010)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2010-04-24
    Description: Nontyphoidal Salmonellae are a major cause of life-threatening bacteremia among HIV-infected individuals. Although cell-mediated immunity controls intracellular infection, antibodies protect against Salmonella bacteremia. We report that high-titer antibodies specific for Salmonella lipopolysaccharide (LPS) are associated with a lack of Salmonella-killing in HIV-infected African adults. Killing was restored by genetically shortening LPS from the target Salmonella or removing LPS-specific antibodies from serum. Complement-mediated killing of Salmonella by healthy serum is shown to be induced specifically by antibodies against outer membrane proteins. This killing is lost when excess antibody against Salmonella LPS is added. Thus, our study indicates that impaired immunity against nontyphoidal Salmonella bacteremia in HIV infection results from excess inhibitory antibodies against Salmonella LPS, whereas serum killing of Salmonella is induced by antibodies against outer membrane proteins.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3772309/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3772309/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉MacLennan, Calman A -- Gilchrist, James J -- Gordon, Melita A -- Cunningham, Adam F -- Cobbold, Mark -- Goodall, Margaret -- Kingsley, Robert A -- van Oosterhout, Joep J G -- Msefula, Chisomo L -- Mandala, Wilson L -- Leyton, Denisse L -- Marshall, Jennifer L -- Gondwe, Esther N -- Bobat, Saeeda -- Lopez-Macias, Constantino -- Doffinger, Rainer -- Henderson, Ian R -- Zijlstra, Eduard E -- Dougan, Gordon -- Drayson, Mark T -- MacLennan, Ian C M -- Molyneux, Malcolm E -- 067321/Wellcome Trust/United Kingdom -- BB/F022778/1/Biotechnology and Biological Sciences Research Council/United Kingdom -- G0701275/Medical Research Council/United Kingdom -- G108/574/Medical Research Council/United Kingdom -- G8402371/Medical Research Council/United Kingdom -- G9818340/Medical Research Council/United Kingdom -- Biotechnology and Biological Sciences Research Council/United Kingdom -- Medical Research Council/United Kingdom -- Wellcome Trust/United Kingdom -- New York, N.Y. -- Science. 2010 Apr 23;328(5977):508-12. doi: 10.1126/science.1180346.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Medical Research Council Centre for Immune Regulation and Clinical Immunology Service, Institute of Biomedical Research, School of Immunity and Infection, University of Birmingham, Birmingham, UK. c.maclennan@bham.ac.uk〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/20413503" target="_blank"〉PubMed〈/a〉

    Notes: Abstract Specific immunofluorescence (IF) staining is helpful and often decisive in diagnosis of deep mycoses by examination of host tissue sections. Brightness of fluorescence may be significantly enhanced by prior digestion of tissues with trypsin, but the treatment tends to separate sections from slides. This is avoided by replacement of albumin in the process by an inexpensive commercial product, Elmer's Glue-All. The entire IF staining procedure for fungi in tissue sections is reviewed here, with emphasis on adhesion and digestion of sections.
