Description: Viral infection is commonly associated with virus-driven hijacking of host proteins. Here we describe a novel mechanism by which influenza virus affects host cells through the interaction of influenza non-structural protein 1 (NS1) with the infected cell epigenome. We show that the NS1 protein of influenza A H3N2 subtype possesses a histone-like sequence (histone mimic) that is used by the virus to target the human PAF1 transcription elongation complex (hPAF1C). We demonstrate that binding of NS1 to hPAF1C depends on the NS1 histone mimic and results in suppression of hPAF1C-mediated transcriptional elongation. Furthermore, human PAF1 has a crucial role in the antiviral response. Loss of hPAF1C binding by NS1 attenuates influenza infection, whereas hPAF1C deficiency reduces antiviral gene expression and renders cells more susceptible to viruses. We propose that the histone mimic in NS1 enables the influenza virus to affect inducible gene expression selectively, thus contributing to suppression of the antiviral response.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3598589/" 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/PMC3598589/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Marazzi, Ivan -- Ho, Jessica S Y -- Kim, Jaehoon -- Manicassamy, Balaji -- Dewell, Scott -- Albrecht, Randy A -- Seibert, Chris W -- Schaefer, Uwe -- Jeffrey, Kate L -- Prinjha, Rab K -- Lee, Kevin -- Garcia-Sastre, Adolfo -- Roeder, Robert G -- Tarakhovsky, Alexander -- 1K99AI095320-01/AI/NIAID NIH HHS/ -- CA129325/CA/NCI NIH HHS/ -- HHSN266200700010C/PHS HHS/ -- R01 CA129325/CA/NCI NIH HHS/ -- R01AI046954/AI/NIAID NIH HHS/ -- R01AI068058/AI/NIAID NIH HHS/ -- U19AI083025/AI/NIAID NIH HHS/ -- England -- Nature. 2012 Mar 14;483(7390):428-33. doi: 10.1038/nature10892.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Laboratory of Immune Cell Epigenetics and Signaling, The Rockefeller University, 1230 York Avenue, New York, New York 10065, USA. imarazzi@rockefeller.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/22419161" target="_blank"〉PubMed〈/a〉

Description: The type I interferon (IFN) response protects cells from viral infection by inducing hundreds of interferon-stimulated genes (ISGs), some of which encode direct antiviral effectors. Recent screening studies have begun to catalogue ISGs with antiviral activity against several RNA and DNA viruses. However, antiviral ISG specificity across multiple distinct classes of viruses remains largely unexplored. Here we used an ectopic expression assay to screen a library of more than 350 human ISGs for effects on 14 viruses representing 7 families and 11 genera. We show that 47 genes inhibit one or more viruses, and 25 genes enhance virus infectivity. Comparative analysis reveals that the screened ISGs target positive-sense single-stranded RNA viruses more effectively than negative-sense single-stranded RNA viruses. Gene clustering highlights the cytosolic DNA sensor cyclic GMP-AMP synthase (cGAS, also known as MB21D1) as a gene whose expression also broadly inhibits several RNA viruses. In vitro, lentiviral delivery of enzymatically active cGAS triggers a STING-dependent, IRF3-mediated antiviral program that functions independently of canonical IFN/STAT1 signalling. In vivo, genetic ablation of murine cGAS reveals its requirement in the antiviral response to two DNA viruses, and an unappreciated contribution to the innate control of an RNA virus. These studies uncover new paradigms for the preferential specificity of IFN-mediated antiviral pathways spanning several virus families.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4077721/" 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/PMC4077721/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Schoggins, John W -- MacDuff, Donna A -- Imanaka, Naoko -- Gainey, Maria D -- Shrestha, Bimmi -- Eitson, Jennifer L -- Mar, Katrina B -- Richardson, R Blake -- Ratushny, Alexander V -- Litvak, Vladimir -- Dabelic, Rea -- Manicassamy, Balaji -- Aitchison, John D -- Aderem, Alan -- Elliott, Richard M -- Garcia-Sastre, Adolfo -- Racaniello, Vincent -- Snijder, Eric J -- Yokoyama, Wayne M -- Diamond, Michael S -- Virgin, Herbert W -- Rice, Charles M -- 099220/Wellcome Trust/United Kingdom -- AI057158/AI/NIAID NIH HHS/ -- AI057160/AI/NIAID NIH HHS/ -- AI083025/AI/NIAID NIH HHS/ -- AI091707/AI/NIAID NIH HHS/ -- AI095611/AI/NIAID NIH HHS/ -- AI104972/AI/NIAID NIH HHS/ -- DK095031/DK/NIDDK NIH HHS/ -- G0801822/Medical Research Council/United Kingdom -- GM076547/GM/NIGMS NIH HHS/ -- GM103511/GM/NIGMS NIH HHS/ -- HHSN266200700010C/PHS HHS/ -- HHSN272200900041CU19/CU/CSP VA/ -- K01 DK095031/DK/NIDDK NIH HHS/ -- R00 AI095320/AI/NIAID NIH HHS/ -- R01 AI032972/AI/NIAID NIH HHS/ -- R01 AI091707/AI/NIAID NIH HHS/ -- R01 AI102597/AI/NIAID NIH HHS/ -- R01 AI104972/AI/NIAID NIH HHS/ -- T32 AI005284/AI/NIAID NIH HHS/ -- T32 AR007279/AR/NIAMS NIH HHS/ -- Howard Hughes Medical Institute/ -- England -- Nature. 2014 Jan 30;505(7485):691-5. doi: 10.1038/nature12862.
