associated (VA) RNAI and VA RNAII. These RNAs are expressed in large amounts late
during a lytic infection. Early studies established an important role for VA RNAI in
maintaining efficient translation in late virus-infected cells by blocking activation of the key
interferon-induced PKR protein kinase. More recent studies have demonstrated that the VA
RNAs also target the RNAi/miRNA pathway. Collectively, available data suggest that the VA …
