Title	Ubiquitination of DEAD-box RNA helicase DDX3X by TRIM25
Description	Tripartite motif protein 25 (TRIM25) is an E3 ligase that ubiquitinates multiple substrates within the RLR signalling cascade and plays both RING (really interesting new gene)-dependent and RING-independent roles in RIG-I-mediated IFN induction. We report that the PRY-SPRY domain of TRIM25 interacts with the N-terminal extension (NTE) of DEAD-box helicase 3X (DDX3X), a host protein with multiple roles in RLR signalling. Gene reporter assays and knockdown studies reveal DDX3X and TRIM25 cooperate to activate the IFN- promoter following RIG-I activation independent of DDX3X’s catalytic activity. We also show that TRIM25 ubiquitinates DDX3X at several lysine residues in vitro and in cells.
