Abstract
Poxvirus genome replication, transcription, translation, and virion assembly occur at sites within the cytoplasm known as factories. Some poxviruses sequester infectious virions outside of the factories in inclusion bodies comprised of numerous copies of the 150-kDa ATI protein, which can provide stability and protection in the environment. We provide evidence that ATI mRNA is anchored by nascent peptides and translated at the inclusion sites rather than in virus factories. Association of ATI mRNA with inclusion bodies allows multiple rounds of local translation and prevents premature ATI protein aggregation and trapping of virions within the factory.
