An RNA virus hijacks an incognito function of a DNA repair enzyme

Abstract excerpt

A previously described mammalian cell activity, called VPg unlinkase, specifically cleaves a unique protein-RNA covalent linkage generated during the viral genomic RNA replication steps of a picornavirus infection. For over three decades, the identity of this cellular activity and its normal role in the uninfected cell had remained elusive. Here we report the purification and identification of VPg unlinkase as...
