PPP1R18 and viral infectious disease: Our identification of differentially expressed genes included several genes that are subunits of protein phosphatase 1 (PP1), particularly PPP1R11, PPP1R3B, and PPP1R18. Previous studies have found that PP1 plays a role in dephosphorylating PP1 to reduce translation during some viral infections and recent studies have indicated a potential role in SARS-CoV-2 infections (He et al., 1997; Nekhai et al., 2007; Ilinykh et al., 2014; McDermott et al., 2016).
