Viral infection of mammalian cells prompts the innate immune system to initiate an antiviral response. The recognition of the virus triggers several antiviral signalling pathways, which among others include the family of 2'-5' oligoadenylate synthetase (OAS) proteins. The p59 protein encoded by the OAS-like (OASL) gene is an atypical member of the OAS family in the sense that it lacks the characteristic 2'-5' oligoadenylate synthetase activity. We decided to investigate the putative antiviral activity of p59 by ectopically expressing this protein in Vero cells and then infecting these cells with virus. We demonstrate that OASL has an antiviral effect against the single-stranded RNA virus picornavirus, encephalomyocarditis virus, but not against a large DNA virus, herpes simplex virus 1. Importantly, this antiviral activity was lost in a truncated version of p59 lacking the ubiquitin-like C-terminal domain of p59. Taken together our results indicate that p59 is indeed an antiviral protein that works through a novel mechanism distinct from other OAS proteins.
