Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) causes coronavirus disease 2019 (COVID-19). SARS-CoV-2 relies on cellular RNA-binding proteins (RBPs) to replicate and spread, although which RBPs control its life cycle remains largely unknown. Here, we employ a multi-omic approach to identify systematically and comprehensively the cellular and viral RBPs that are involved in SARS-CoV-2 infection. We reveal that SARS-CoV-2 infection profoundly remodels the cellular RNA-bound proteome, which includes wide-ranging effects on RNA metabolic pathways, non-canonical RBPs, and antiviral factors. Moreover, we apply a new method to identify the proteins that directly interact with viral RNA, uncovering dozens of cellular RBPs and six viral proteins. Among them are several components of the tRNA ligase complex, which we show regulate SARS-CoV-2 infection. Furthermore, we discover that available drugs targeting host RBPs that interact with SARS-CoV-2 RNA inhibit infection. Collectively, our results uncover a new universe of host-virus interactions with potential for new antiviral therapies against COVID-19. A third of the RBPome remodels upon SARS-CoV-2 infection Viral RNPs include 139 cellular and 6 viral RBPs Inhibition of these cellular RBPs hampers SARS-CoV-2 infection The tRNA ligase complex is a key regulator of SARS-CoV-2 Kamel et al. apply a multi-omic approach to identify the RNA-binding proteins that regulate SARS-CoV-2 infection. They discovered that the complement of RNA-binding proteins heavily remodels upon SARS-CoV-2 infection. They also show that the viral RNA interacts with dozens of cellular and six viral RNA-binding proteins. These host-virus interactions are fundamental for SARS-CoV-2 infection and have great potential for new therapeutic approaches against COVID-19.
