Virus restriction: Repurposing an essential cellular function to defend against viruses


Eukaryotes are continually subjected to viral infections and, in response, have evolved a wide range of defence mechanisms. Two recent studies show how a duplicated copy of a cellular protein needed for cell growth and virus egress evolved to inhibit viruses while preserving cell viability.
