| Abstract | V accessory proteins from Paramyxoviruses are important in viral evasion of the innate immune response. Here, using a cell survival assay that identifies both inhibitors and activators of interferon regulatory factor 3 (IRF3)-mediated gene induction, we identified select paramyxoviral V proteins that inhibited double-stranded RNA-mediated signaling; these are encoded by mumps virus (MuV), human parainfluenza virus 2 (hPIV2), and parainfluenza virus 5 (PIV5), all members of the genus Rubulavirus. We showed that interaction between V and the IRF3/7 kinases, TRAF family member-associated NFkappaB activator (TANK)-binding kinase 1 (TBK1)/inhibitor of kappaB kinase epsilon (IKKe), was essential for this inhibition. Indeed, V proteins were phosphorylated directly by TBK1/IKKe, and this, intriguingly, resulted in lowering of the cellular level of V. Thus, it appears that V mimics IRF3 in both its phosphorylation by TBK1/IKKe and its subsequent degradation. Finally, a PIV5 mutant encoding a V protein that could not inhibit IKKe was much more susceptible to the antiviral effects of double-stranded RNA than the wild-type virus. Because many innate immune response signaling pathways, including those initiated by TLR3, TLR4, RIG-I, MDA5, and DNA-dependent activator of IRFs (DAI), use TBK1/IKKe as the terminal kinases to activate IRFs, rubulaviral V proteins have the potential to inhibit all of them. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
