Abstract
Phase separation of viral biopolymers is a key factor in the formation of cytoplasmic viral inclusions, known as sites of virus replication and assembly. This review describes the mechanisms and factors that affect phase separation in viral replication and identifies potential areas for future research. Drawing inspiration from studies on cellular RNA-rich condensates, we compare the hierarchical coassembly of ribosomal RNAs and proteins in the nucleolus to the coordinated coassembly of viral RNAs and proteins taking place within viral factories in viruses containing segmented RNA genomes. We highlight the common characteristics of biomolecular condensates in viral replication and how this new understanding is reshaping our views of virus assembly mechanisms. Such studies have the potential to uncover unexplored antiviral strategies targeting these phase-separated states.
期刊介绍：
The Annual Review of Virology serves as a conduit for disseminating thrilling advancements in our comprehension of viruses spanning animals, plants, bacteria, archaea, fungi, and protozoa. Its reviews illuminate novel concepts and trajectories in basic virology, elucidating viral disease mechanisms, exploring virus-host interactions, and scrutinizing cellular and immune responses to virus infection. These reviews underscore the exceptional capacity of viruses as potent probes for investigating cellular function.
