CC   -!- FUNCTION: [Capsid protein VP1]: Forms an icosahedral capsid of pseudo
CC       T=3 symmetry with capsid proteins VP2 and VP3 (By similarity). The
CC       capsid is 300 Angstroms in diameter, composed of 60 copies of each
CC       capsid protein and enclosing the viral positive strand RNA genome (By
CC       similarity). Capsid protein VP1 mainly forms the vertices of the capsid
CC       (By similarity). Capsid protein VP1 interacts with host cell receptor
CC       PVR to provide virion attachment to target host cells (By similarity).
CC       This attachment induces virion internalization predominantly through
CC       clathrin- and caveolin-independent endocytosis in Hela cells and
CC       through caveolin-mediated endocytosis in brain microvascular
CC       endothelial cells (By similarity). Tyrosine kinases are probably
CC       involved in the entry process (By similarity). Virus binding to PVR
CC       induces increased junctional permeability and rearrangement of
CC       junctional proteins (By similarity). Modulation of endothelial tight
CC       junctions, as well as cytolytic infection of endothelial cells
CC       themselves, may result in loss of endothelial integrity which may help
CC       the virus to reach the CNS (By similarity). After binding to its
CC       receptor, the capsid undergoes conformational changes (By similarity).
CC       Capsid protein VP1 N-terminus (that contains an amphipathic alpha-
CC       helix) and capsid protein VP4 are externalized (By similarity).
CC       Together, they shape a pore in the host membrane through which viral
CC       genome is translocated to host cell cytoplasm (By similarity).
CC       {ECO:0000250|UniProtKB:P03300}.
CC   -!- FUNCTION: [Capsid protein VP2]: Forms an icosahedral capsid of pseudo
CC       T=3 symmetry with capsid proteins VP2 and VP3 (By similarity). The
CC       capsid is 300 Angstroms in diameter, composed of 60 copies of each
CC       capsid protein and enclosing the viral positive strand RNA genome (By
CC       similarity). {ECO:0000250|UniProtKB:P03300}.
CC   -!- FUNCTION: [Capsid protein VP3]: Forms an icosahedral capsid of pseudo
CC       T=3 symmetry with capsid proteins VP2 and VP3 (By similarity). The
CC       capsid is 300 Angstroms in diameter, composed of 60 copies of each
CC       capsid protein and enclosing the viral positive strand RNA genome (By
CC       similarity). {ECO:0000250|UniProtKB:P03300}.
CC   -!- FUNCTION: [Capsid protein VP4]: Lies on the inner surface of the capsid
CC       shell (By similarity). After binding to the host receptor, the capsid
CC       undergoes conformational changes (By similarity). Capsid protein VP4 is
CC       released, Capsid protein VP1 N-terminus is externalized, and together,
CC       they shape a pore in the host membrane through which the viral genome
CC       is translocated into the host cell cytoplasm (By similarity).
CC       {ECO:0000250|UniProtKB:P03300}.
CC   -!- FUNCTION: [Capsid protein VP0]: Component of immature procapsids, which
CC       is cleaved into capsid proteins VP4 and VP2 after maturation (By
CC       similarity). Allows the capsid to remain inactive before the maturation
CC       step (By similarity). {ECO:0000250|UniProtKB:P03300}.
CC   -!- FUNCTION: [Protease 2A]: Cysteine protease that cleaves viral
CC       polyprotein and specific host proteins (By similarity). It is
CC       responsible for the autocatalytic cleavage between the P1 and P2
CC       regions, which is the first cleavage occurring in the polyprotein (By
CC       similarity). Cleaves also the host translation initiation factor
CC       EIF4G1, in order to shut down the capped cellular mRNA translation (By
CC       similarity). Inhibits the host nucleus-cytoplasm protein and RNA
CC       trafficking by cleaving host members of the nuclear pores including
CC       NUP98, NUP62 and NUP153 (By similarity). Counteracts stress granule
CC       formation probably by antagonizing its assembly or promoting its
CC       dissassembly (By similarity). Cleaves and inhibits host IFIH1/MDA5,
CC       thereby inhibiting the type-I IFN production and the establishment of
CC       the antiviral state (By similarity). Cleaves and inhibits host MAVS,
CC       thereby inhibiting the type-I IFN production and the establishment of
CC       the antiviral state (By similarity). {ECO:0000250|UniProtKB:P03300,
CC       ECO:0000250|UniProtKB:P03301}.
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:P03300}.
CC   -!- FUNCTION: [Protein 2C]: Induces and associates with structural
CC       rearrangements of intracellular membranes. Displays RNA-binding,
CC       nucleotide binding and NTPase activities. May play a role in virion
CC       morphogenesis and viral RNA encapsidation by interacting with the
CC       capsid protein VP3. {ECO:0000250|UniProtKB:P03300}.
CC   -!- FUNCTION: [Protein 3AB]: Localizes the viral replication complex to the
CC       surface of membranous vesicles. Together with protein 3CD binds the
CC       Cis-Active RNA Element (CRE) which is involved in RNA synthesis
CC       initiation. Acts as a cofactor to stimulate the activity of 3D
CC       polymerase, maybe through a nucleid acid chaperone activity.
CC       {ECO:0000250|UniProtKB:P03300}.
CC   -!- FUNCTION: [Protein 3A]: Localizes the viral replication complex to the
CC       surface of membranous vesicles (By similarity). It inhibits host cell
CC       endoplasmic reticulum-to-Golgi apparatus transport and causes the
CC       disassembly of the Golgi complex, possibly through GBF1 interaction (By
CC       similarity). This would result in depletion of MHC, trail receptors and
CC       IFN receptors at the host cell surface (By similarity). Plays an
CC       essential role in viral RNA replication by recruiting ACBD3 and PI4KB
CC       at the viral replication sites, thereby allowing the formation of the
CC       rearranged membranous structures where viral replication takes place
CC       (By similarity). {ECO:0000250|UniProtKB:P03300}.
CC   -!- FUNCTION: [Viral protein genome-linked]: Acts as a primer for viral RNA
CC       replication and remains covalently bound to viral genomic RNA. VPg is
CC       uridylylated prior to priming replication into VPg-pUpU (By
CC       similarity). The oriI viral genomic sequence may act as a template for
CC       this. The VPg-pUpU is then used as primer on the genomic RNA poly(A) by
CC       the RNA-dependent RNA polymerase to replicate the viral genome (By
CC       similarity). Following genome release from the infecting virion in the
CC       cytoplasm, the VPg-RNA linkage is probably removed by host TDP2 (By
CC       similarity). During the late stage of the replication cycle, host TDP2
CC       is excluded from sites of viral RNA synthesis and encapsidation,
CC       allowing for the generation of progeny virions (By similarity).
CC       {ECO:0000250|UniProtKB:P03300}.
CC   -!- FUNCTION: [Protein 3CD]: Involved in the viral replication complex and
CC       viral polypeptide maturation. It exhibits protease activity with a
CC       specificity and catalytic efficiency that is different from protease
CC       3C. Protein 3CD lacks polymerase activity. Protein 3CD binds to the
CC       5'UTR of the viral genome. {ECO:0000250|UniProtKB:P03300}.
CC   -!- FUNCTION: [Protease 3C]: Major viral protease that mediates proteolytic
CC       processing of the polyprotein (By similarity). Cleaves host EIF5B,
CC       contributing to host translation shutoff (By similarity). Cleaves also
CC       host PABPC1, contributing to host translation shutoff (By similarity).
CC       Cleaves host DDX58/RIG-I and thus contributes to the inhibition of type
CC       I interferon production (By similarity). Cleaves host NLRP1, triggers
CC       host N-glycine-mediated degradation of the autoinhibitory NLRP1 N-
CC       terminal fragment (By similarity). {ECO:0000250|UniProtKB:P03300,
CC       ECO:0000250|UniProtKB:P03303}.
CC   -!- FUNCTION: [RNA-directed RNA polymerase]: Replicates the viral genomic
CC       RNA on the surface of intracellular membranes. May form linear arrays
CC       of subunits that propagate along a strong head-to-tail interaction
CC       called interface-I. Covalently attaches UMP to a tyrosine of VPg, which
CC       is used to prime RNA synthesis. The positive stranded RNA genome is
CC       first replicated at virus induced membranous vesicles, creating a dsRNA
CC       genomic replication form. This dsRNA is then used as template to
CC       synthesize positive stranded RNA genomes. ss(+)RNA genomes are either
CC       translated, replicated or encapsidated. {ECO:0000250|UniProtKB:P03300}.

CC       similarity). The N-terminus is involved in oligomerization (By
CC       similarity). The central part contains an ATPase domain and a C4-type
CC       zinc-finger (By similarity). The C-terminus is involved in RNA-binding
CC       (By similarity). The extreme C-terminus contains a region involved in
CC       oligomerization (By similarity). {ECO:0000250|UniProtKB:P03300}.
CC   -!- PTM: [Genome polyprotein]: Specific enzymatic cleavages in vivo by the
CC       viral proteases yield processing intermediates and the mature proteins.
CC       {ECO:0000250|UniProtKB:P03300}.
CC   -!- PTM: [Capsid protein VP0]: Myristoylation is required for the formation
CC       of pentamers during virus assembly. Further assembly of 12 pentamers
CC       and a molecule of genomic RNA generates the provirion.
CC       {ECO:0000250|UniProtKB:P03300}.
CC   -!- PTM: [Capsid protein VP0]: During virion maturation, immature virions
CC       are rendered infectious following cleavage of VP0 into VP4 and VP2.
CC       This maturation seems to be an autocatalytic event triggered by the
CC       presence of RNA in the capsid and it is followed by a conformational
CC       change infectious virion. {ECO:0000250|UniProtKB:P03300}.
CC   -!- PTM: [Capsid protein VP4]: Myristoylation is required during RNA
CC       encapsidation and formation of the mature virus particle.
CC       {ECO:0000250|UniProtKB:P03300}.
CC   -!- PTM: [Viral protein genome-linked]: VPg is uridylylated by the
CC       polymerase into VPg-pUpU. This acts as a nucleotide-peptide primer for
CC       the genomic RNA replication. {ECO:0000250|UniProtKB:P03300}.
CC   -!- SIMILARITY: Belongs to the picornaviruses polyprotein family.
CC       {ECO:0000305}.
