CC -!- FUNCTION: [Leader protease]: Autocatalytically cleaves itself from the
CC polyprotein at the L/VP0 junction. Cleaves also the host translation
CC initiation factors EIF4G1 and EIF4G3, in order to shutoff the capped
CC cellular mRNA transcription. Plays a role in counteracting host innate
CC antiviral response using diverse mechanisms. Possesses a deubiquitinase
CC activity acting on both 'Lys'-48 and 'Lys'-63-linked polyubiquitin
CC chains. In turn, inhibits the ubiquitination and subsequent activation
CC of key signaling molecules of type I IFN response such as host DDX58,
CC TBK1, TRAF3 and TRAF6. Inhibits host NF-kappa-B activity by inducing a
CC decrease in RELA mRNA levels. Cleaves a peptide bond in the C-terminus
CC of host ISG15, resulting in the damaging of this mofidier that can no
CC longer be attached to target proteins. Cleaves also host G3BP1 and
CC G3BP2 in order to inhibit cytoplasmic stress granules assembly.
CC {ECO:0000250|UniProtKB:P03305, ECO:0000250|UniProtKB:P03308}.
CC -!- FUNCTION: [Capsid protein VP4]: Lies on the inner surface of the capsid
CC shell. After binding to the host receptor, the capsid undergoes
CC conformational changes. Capsid protein VP4 is released, capsid protein
CC VP1 N-terminus is externalized, and together, they shape a pore in the
CC host membrane through which the viral genome is translocated into the
CC host cell cytoplasm. After genome has been released, the channel
CC shrinks. {ECO:0000250|UniProtKB:P03300}.
CC -!- FUNCTION: [Capsid protein VP2]: Forms an icosahedral capsid of pseudo
CC T=3 symmetry with capsid proteins VP1 and VP3. The capsid is composed
CC of 60 copies of each capsid protein organized in the form of twelve
CC pentamers and encloses the viral positive strand RNA genome.
CC {ECO:0000250|UniProtKB:P03305}.
CC -!- FUNCTION: [Capsid protein VP1]: Forms an icosahedral capsid of pseudo
CC T=3 symmetry with capsid proteins VP2 and VP3. The capsid is composed
CC of 60 copies of each capsid protein organized in the form of twelve
CC pentamers and encloses the viral positive strand RNA genome. Mediates
CC cell entry by attachment to an integrin receptor, usually host
CC ITGAV/ITGB6. In addition, targets host MAVS to suppress type I IFN
CC pathway. {ECO:0000250|UniProtKB:P03305}.
CC -!- FUNCTION: [Capsid protein VP3]: Forms an icosahedral capsid of pseudo
CC T=3 symmetry with capsid proteins VP0 and VP3. The capsid is composed
CC of 60 copies of each capsid protein organized in the form of twelve
CC pentamers and encloses the viral positive strand RNA genome.
CC {ECO:0000250|UniProtKB:P03305}.
CC -!- FUNCTION: [Protein 2A]: Mediates self-processing of the polyprotein by
CC a translational effect termed 'ribosome skipping'. Mechanistically, 2A-
CC mediated cleavage occurs between the C-terminal glycine and the proline
CC of the downstream protein 2B. In the case of foot-and-mouth disease
CC virus, the 2A oligopeptide is post-translationally 'trimmed' from the
CC C-terminus of the upstream protein 1D by 3C proteinase.
CC {ECO:0000250|UniProtKB:P03305}.
CC -!- FUNCTION: [Protein 2B]: Plays an essential role in the virus
CC replication cycle by acting as a viroporin. Creates a pore in the host
CC reticulum endoplasmic and as a consequence releases Ca2+ in the
CC cytoplasm of infected cell. In turn, high levels of cytoplasmic calcium
CC may trigger membrane trafficking and transport of viral ER-associated
CC proteins to viroplasms, sites of viral genome replication.
CC {ECO:0000250|UniProtKB:P03305}.
CC -!- FUNCTION: [Protein 2C]: Associates with and induces structural
CC rearrangements of intracellular membranes. Triggers host autophagy by
CC interacting with host BECN1 and thereby promotes viral replication.
CC Participates in viral replication and interacts with host DHX9.
CC Displays RNA-binding, nucleotide binding and NTPase activities. May
CC play a role in virion morphogenesis and viral RNA encapsidation by
CC interacting with the capsid protein VP3.
CC {ECO:0000250|UniProtKB:P03305}.
CC -!- FUNCTION: [Protein 3A]: Plays important roles in virus replication,
CC virulence and host range. {ECO:0000250|UniProtKB:P03305}.
CC -!- FUNCTION: [Protein 3B-1]: Covalently linked to the 5'-end of both the
CC positive-strand and negative-strand genomic RNAs. Acts as a genome-
CC linked replication primer. {ECO:0000250|UniProtKB:P03305}.
CC -!- FUNCTION: [Protein 3B-2]: Covalently linked to the 5'-end of both the
CC positive-strand and negative-strand genomic RNAs. Acts as a genome-
CC linked replication primer. {ECO:0000250|UniProtKB:P03305}.
CC -!- FUNCTION: [Protein 3B-3]: Covalently linked to the 5'-end of both the
CC positive-strand and negative-strand genomic RNAs. Acts as a genome-
CC linked replication primer. {ECO:0000250|UniProtKB:P03305}.
CC -!- FUNCTION: [Protease 3C]: Cysteine protease that generates mature viral
CC proteins from the precursor polyprotein. In addition to its proteolytic
CC activity, binds to viral RNA and thus influences viral genome
CC replication. RNA and substrate bind cooperatively to the protease.
CC {ECO:0000250|UniProtKB:P03305}.
CC -!- FUNCTION: RNA-directed RNA polymerase 3D-POL replicates genomic and
CC antigenomic RNA by recognizing replications specific signals.
CC Covalently attaches UMP to a tyrosine of VPg, which is used to prime
CC RNA synthesis. The positive stranded RNA genome is first replicated at
CC virus induced membranous vesicles, creating a dsRNA genomic replication
CC form. This dsRNA is then used as template to synthesize positive
CC stranded RNA genomes. ss(+)RNA genomes are either translated,
CC replicated or encapsidated. {ECO:0000250|UniProtKB:P03305}.

CC -!- PTM: Specific enzymatic cleavages in vivo by the viral proteases yield
CC a variety of precursors and mature proteins. Polyprotein processing
CC intermediates such as VP0 which is a VP4-VP2 precursor are produced.
CC During virion maturation, non-infectious particles are rendered
CC infectious following cleavage of VP0. This maturation cleavage is
CC followed by a conformational change of the particle. The polyprotein
CC seems to be cotranslationally cleaved at the 2A/2B junction by a
CC ribosomal skip from one codon to the next without formation of a
CC peptide bond. This process would release the L-P1-2A peptide from the
CC translational complex (By similarity). {ECO:0000250}.
CC -!- PTM: Myristoylation of VP4 is required during RNA encapsidation and
CC formation of the mature virus particle. {ECO:0000250}.
CC -!- PTM: Protein 3B-1, 3B-2 and 3B-3 are uridylylated by the polymerase and
CC are covalently linked to the 5'-end of genomic RNA. These uridylylated
CC forms act as a nucleotide-peptide primer for the polymerase (By
CC similarity). {ECO:0000250}.
CC -!- MISCELLANEOUS: The capsid protein VP1 contains the main antigenic
CC determinants of the virion; therefore, changes in its sequence must be
CC responsible for the high antigenic variability of the virus.
CC {ECO:0000250}.
CC -!- SIMILARITY: Belongs to the picornaviruses polyprotein family.
CC {ECO:0000305}.
