    • Abstract

       

      Classical swine fever (CSF) is a contagious disease with a high mortality rate and is caused by classical swine fever virus(CSFV). CSFV non-structural protein 4B (NS4B) plays a crucial role in CSFV replication and pathogenicity. However,precisely how NS4B exerts these functions remains unknown, especially as there are no reports relating to potential cellularpartners of CSFV NS4B. Here, a yeast two-hybrid (Y2H) system was used to screen the cellular proteins interacting withNS4B from a porcine alveolar macrophage (PAM) cDNA library. The protein screen along with alignment using the NCBIdatabase revealed 14 cellular proteins that interact with NS4B: DDX39B, COX7C, FTH1, MAVS, NR2F6, RPLP1,PSMC4, FGL2, MKRN1, RPL15, RPS3, RAB22A, TP53BP2 and TBK1. These proteins mostly relate to oxidoreductaseactivity, signal transduction, localization, biological regulation, catalytic activity, transport and metabolism by GO categories.Tank-binding kinase 1 (TBK1) was chosen for further confirmation. The NS4B-TBK1 interaction was furtherconfirmed by subcellular co-location, co-immunoprecipitation and glutathione S-transferase pull-down assays. This studyoffers a theoretical foundation for further understanding of the diversity of NS4B functions in relation to viral infection andsubsequent pathogenesis.

      Forthcoming Special issue.


    • To trigger further research on plant mitochondria, the Journal of Biosciences is bringing out a special issue titled "Plant Mitochondria: Properties and Interactions with Other Organelles".


      Plant mitochondria are quite distinct and have unique features, such as a cyanide-insensitive alternate pathway. They also interact with chloroplasts to optimize photosynthetic carbon assimilation.


      Submissions are welcome until 30 July 2023. The contributions can be original articles, short communications, reviews, or mini-reviews on any topic related to plant mitochondria.


      Authors can submit their articles online at https://www.editorialmanager.com/jbsc/default2.aspx
