A crucial step of the viral life cycle of Kaposi’s Sarcoma Herpesvirus (KSHV) lytic infection is the triggering of a massive RNA decay event termed “Host Shutoff”. Host Shutoff is driven by the viral endonuclease SOX which leads to the destruction of over 70% of the total transcriptome. This process cripples cellular gene expression and allows for viral reprograming of the cell for the purpose of viral replication. Co-evolution has led to the host developing a multitude of antiviral defenses aimed at preserving certain cellular RNAs linked to antiviral responses. One such defense are RNA secondary structures located within the …
