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 DDX58, 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.

By similarity

Lies on the inner surface of the capsid shell. After binding to the host receptor, the capsid undergoes conformational changes. Capsid protein VP4 is released, capsid protein VP1 N-terminus is externalized, and together, they shape a pore in the host membrane through which the viral genome is translocated into the host cell cytoplasm. After genome has been released, the channel shrinks.

By similarity

Forms an icosahedral capsid of pseudo T=3 symmetry with capsid proteins VP1 and VP3. The capsid is composed of 60 copies of each capsid protein organized in the form of twelve pentamers and encloses the viral positive strand RNA genome.

By similarity

Forms an icosahedral capsid of pseudo T=3 symmetry with capsid proteins VP2 and VP3. The capsid is composed of 60 copies of each capsid protein organized in the form of twelve pentamers and encloses the viral positive strand RNA genome. Mediates cell entry by attachment to an integrin receptor, usually host ITGAV/ITGB6. In addition, targets host MAVS to suppress type I IFN pathway.

By similarity

Forms an icosahedral capsid of pseudo T=3 symmetry with capsid proteins VP0 and VP3. The capsid is composed of 60 copies of each capsid protein organized in the form of twelve pentamers and encloses the viral positive strand RNA genome.

By similarity

Mediates self-processing of the polyprotein by a translational effect termed 'ribosome skipping'. Mechanistically, 2A-mediated cleavage occurs between the C-terminal glycine and the proline of the downstream protein 2B. In the case of foot-and-mouth disease virus, the 2A oligopeptide is post-translationally 'trimmed' from the C-terminus of the upstream protein 1D by 3C proteinase.

By similarity

Plays an essential role in the virus replication cycle by acting as a viroporin. Creates a pore in the host reticulum endoplasmic and as a consequence releases Ca2+ in the cytoplasm of infected cell. In turn, high levels of cytoplasmic calcium may trigger membrane trafficking and transport of viral ER-associated proteins to viroplasms, sites of viral genome replication.

By similarity

Associates with and induces structural rearrangements of intracellular membranes. Triggers host autophagy by interacting with host BECN1 and thereby promotes viral replication. Participates in viral replication and interacts with host DHX9. Displays RNA-binding, nucleotide binding and NTPase activities. May play a role in virion morphogenesis and viral RNA encapsidation by interacting with the capsid protein VP3.

By similarity

Plays important roles in virus replication, virulence and host range.

By similarity

Covalently linked to the 5'-end of both the positive-strand and negative-strand genomic RNAs. Acts as a genome-linked replication primer.

By similarity

Covalently linked to the 5'-end of both the positive-strand and negative-strand genomic RNAs. Acts as a genome-linked replication primer.

By similarity

Cysteine protease that generates mature viral proteins from the precursor polyprotein. In addition to its proteolytic activity, binds to viral RNA and thus influences viral genome replication. RNA and substrate bind cooperatively to the protease.

By similarity

RNA-directed RNA polymerase 3D-POL replicates genomic and antigenomic RNA by recognizing replications specific signals. Covalently attaches UMP to a tyrosine of VPg, which is used to prime RNA synthesis. The positive stranded RNA genome is first replicated at virus induced membranous vesicles, creating a dsRNA genomic replication form. This dsRNA is then used as template to synthesize positive stranded RNA genomes. ss+RNA genomes are either translated, replicated or encapsidated.

By similarity

Miscellaneous

The capsid protein VP1 contains the main antigenic determinants of the virion; therefore, changes in its sequence must be responsible for the high antigenic variability of the virus.By similarity

Specific enzymatic cleavages in vivo by the viral proteases yield a variety of precursors and mature proteins. Polyprotein processing intermediates such as VP0 which is a VP4-VP2 precursor are produced. During virion maturation, non-infectious particles are rendered infectious following cleavage of VP0. This maturation cleavage is followed by a conformational change of the particle. The polyprotein seems to be cotranslationally cleaved at the 2A/2B junction by a ribosomal skip from one codon to the next without formation of a peptide bond. This process would release the L-P1-2A peptide from the translational complex (By similarity).By similarity
Myristoylation of VP4 is required during RNA encapsidation and formation of the mature virus particle.By similarity
