TRAF3 binds with both IPS-1 and downstream interferon regulatory factor 3/7 (IRF3/7) kinases TBK1 and IKK-epsilon (IKKi) and thus serves as a critical link between RIG-I/MDA5 adaptors and downstream regulatory kinases important for interferon regulatory factor (IRF) activation (Oganesyan et al).
SIKE (for Suppressor of IKKepsilon) interacts with IKKepsilon and TBK1. SIKE is associated with TBK1 under physiological condition and dissociated from TBK1 upon viral infection. Overexpression of SIKE disrupted the interactions of IKKepsilon or TBK1 with RIG-I.
