Upon SARS-CoV-2 infection a strong global decrease in steady-state mRNA levels (relative to ncRNA levels) is observed. Many of the key genes stimulated by IFN are spliced, and an increase in intron retention in multiple IFN-responsive genes (such as ISG15 and RIG-I) is seen in infected human lung epithelial cells (Calu3). SARS-CoV-2 nonstructural protein 16 (nsp16), besides its role in viral RNA cap modification, binds to the 5′ splice site recognition sequence of U1 snRNA and the branchpoint recognition site of U2 snRNA, both parts of the spliceosome, disrupting global mRNA splicing (Banerjee et al, 2020).
