Ubiquitin conjugating E2 enzymes UBC13 and UBCH6 are targets for ISGylation. This suppresses the ubiquitin-conjugating activity of both UBC13 and UBCH6. This modification may play an important role in the control of signal transduction pathways, such as the NF-kB pathway, which are associated with K63-linked polyubiquitination (Takeuchi et al, 2005).
