TRAFs are E3 ubiquitin ligases that catalyse Lys63-polyubquitination of associated target proteins and possibly on themselves.
Virus- triggered Lys63-polyubiquitination of TRAF3/ or TRAF6 was shown to be essential for induction of IFN production [Mao AP et al 2010]. Furthermore, Kayagaki et al. demonstrated that deubiquitinating enzyme A (DUBA) specifically removed Lys63-linked polyubiquitin chains from TRAF3, resulting in its dissociation from the IFN signaling complex [Kayagaki N et al 2007].
