| Background | Genome polyprotein (Lpro) is a ~259 kDa protein. Autocatalytically cleaves itself from the polyprotein at the L/VP0 junction. Also cleaves the host translation initiation factors EIF4G1 and EIF4G3, in order to shut off the capped cellular mRNA transcription. Plays a role in counteracting host innate antiviral response using diverse mechanisms. Possesses a deubiquitinase activity acting on both 'Lys-48' and 'Lys-63'-linked polyubiquitin chains. In turn, inhibits the ubiquitination and subsequent activation of key signaling molecules of type I IFN response such as host RIGI, TBK1, TRAF3 and TRAF6. |
