Interferon stimulated gene 15 (ISG15) is an ubiquitin-like protein whose expression and conjugation to targets (ISGylation) is induced by infection, interferon (IFN)-α and -β, ischemia, DNA damage and aging. Attention has historically focused on the antiviral effects of ISGylation, which blocks the entry, replication or release of ... Weband UbcH8 function as E1 and E2 enzymes for ISGylation, respectively. Cotransfection of 293FT cells with plasmids encod-ing UBE1L, UbcH8, and ISG15 promoted the ISGylation of RIG-I (data not shown). The UbcH8 functions as an E2 enzyme for both ubiquitin and ISG15 conjugation (16, 27–33). We made
