Organism: Foot-and-mouth disease virus serotype O (FMDV)
Function: Autocatalytically cleaves itself from the polyprotein at the L/VP0 junction. Cleaves also the host translation initiation factors EIF4G1 and EIF4G3, in order to shutoff 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. Inhibits host NF-kappa-B activity by inducing a decrease in RELA mRNA levels. Cleaves a peptide bond in the C-terminus of host ISG15, resulting in the damaging of this mofidier that can no longer be attached to target proteins. Cleaves also host G3BP1 and G3BP2 in order to inhibit cytoplasmic stress granules assembly.

Note=Probably localizes to the surface of intracellular membrane vesicles that are induced after virus infection as the site for viral RNA replication. These vesicles are derived from the endoplasmic reticulum (By similarity). {ECO:0000250}.; SUBCELLULAR LOCATION: [Protein 3A]: Host cytoplasm {ECO:0000269|PubMed:24352458, ECO:0000269|PubMed:29536193}. Host endoplasmic reticulum membrane {ECO:0000269|PubMed:25275544}. Note=Interacts with host endoplasmic reticulum membranes through its hydrophobic stretch, while its N- and C-terminus face the cytosol being accessible to other viral proteins for viral replication. {ECO:0000269|PubMed:25275544}.; SUBCELLULAR LOCATION: [Protein 3B-1]: Virion {ECO:0000305}.; SUBCELLULAR LOCATION: [Protein 3B-2]: Virion {ECO:0000305}.; SUBCELLULAR LOCATION: [Protein 3B-3]: Virion {ECO:0000305}.; SUBCELLULAR LOCATION: [Protease 3C]: Host cytoplasm {ECO:0000305}.; SUBCELLULAR LOCATION: [RNA-directed RNA polymerase 3D-POL]: Host cytoplasm {ECO:0000269|PubMed:23886493}.
