Gen. Virol. 67:2093-2102(1986). 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). Also cleaves 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 disassembly (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 endoplasmic reticulum 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. The oriI viral CC genomic sequence may act as a template for this. The VPg-pUpU is then CC used as primer on the genomic RNA poly(A) by the RNA-dependent RNA CC polymerase to replicate the viral genome. During genome replication, CC the VPg-RNA linkage is removed by the host TDP2, thereby accelerating CC replication. 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. 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). Also cleaves CC host PABPC1, contributing to host translation shutoff (By similarity). CC Cleaves host RIGI and thus contributes to the inhibition of type I CC interferon production (By similarity). Cleaves host NLRP1, triggers CC host N-glycine-mediated degradation of the autoinhibitory NLRP1 N- CC terminal fragment (By similarity). Inhibits the integrated stress CC response (ISR) in the infected cell by cleaving host G3BP1 (By CC similarity). Stress granule formation is thus inhibited, which allows CC protein synthesis and viral replication (By similarity). CC {ECO:0000250|UniProtKB:P03300, 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}.
