Virol. 76:7694-7704(2002). CC -!- FUNCTION: [Capsid protein VP1]: Forms an icosahedral capsid of pseudo CC T=3 symmetry with capsid proteins VP2 and VP3. The capsid is 300 CC Angstroms in diameter, composed of 60 copies of each capsid protein and CC enclosing the viral positive strand RNA genome. Capsid protein VP1 CC mainly forms the vertices of the capsid. Capsid protein VP1 interacts CC with host CD55 to provide virion attachment to target host cells. This CC attachment induces virion internalization and is mediated through CC interaction with host FCGRT (PubMed:7517044). Tyrosine kinases are CC probably involved in the entry process. After binding to its receptor, CC the capsid undergoes conformational changes. Capsid protein VP1 N- CC terminus (that contains an amphipathic alpha-helix) and capsid protein CC VP4 are externalized. Together, they shape a pore in the host membrane CC through which viral genome is translocated to host cell cytoplasm. CC After genome has been released, the channel shrinks (By similarity). CC {ECO:0000250, ECO:0000269|PubMed:7517044}. CC -!- FUNCTION: [Capsid protein VP2]: Forms an icosahedral capsid of pseudo CC T=3 symmetry with capsid proteins VP2 and VP3. The capsid is 300 CC Angstroms in diameter, composed of 60 copies of each capsid protein and CC enclosing the viral positive strand RNA genome (By similarity). CC {ECO:0000250}. CC -!- FUNCTION: [Capsid protein VP3]: Forms an icosahedral capsid of pseudo CC T=3 symmetry with capsid proteins VP2 and VP3. The capsid is 300 CC Angstroms in diameter, composed of 60 copies of each capsid protein and CC enclosing the viral positive strand RNA genome (By similarity). CC {ECO:0000250}. 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 (By similarity). {ECO:0000250}. CC -!- FUNCTION: [Capsid protein VP0]: Component of immature procapsids, which CC is cleaved into capsid proteins VP4 and VP2 after maturation. Allows CC the capsid to remain inactive before the maturation step (By CC similarity). {ECO:0000250}. CC -!- FUNCTION: [Protease 2A]: Cysteine protease that cleaves viral CC polyprotein and specific host proteins. It is responsible for the CC cleavage between the P1 and P2 regions, first cleavage occurring in the CC polyprotein. Cleaves also the host translation initiation factor CC EIF4G1, in order to shut down the capped cellular mRNA translation. CC Inhibits the host nucleus-cytoplasm protein and RNA trafficking by CC cleaving host members of the nuclear pores (By similarity). CC {ECO:0000250}. 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 (By CC similarity). {ECO:0000250}. 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 (By similarity). {ECO:0000250}. 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 (By CC similarity). {ECO:0000250}. CC -!- FUNCTION: [Protein 3A]: Localizes the viral replication complex to the CC surface of membranous vesicles. It inhibits host cell endoplasmic CC reticulum-to-Golgi apparatus transport and causes the dissassembly of CC the Golgi complex, possibly through GBF1 interaction. This would result CC in depletion of MHC, trail receptors and IFN receptors at the host cell CC surface (By similarity). {ECO:0000250}. 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. VPg may be removed in the CC cytoplasm by an unknown enzyme termed 'unlinkase'. VPg is not cleaved CC off virion genomes because replicated genomic RNA are encapsidated at CC the site of replication (By similarity). {ECO:0000250}. CC -!- FUNCTION: [Protein 3CD]: Is involved in the viral replication complex CC and 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. The 3C domain in the context CC of protein 3CD may have an RNA binding activity (By similarity). CC {ECO:0000250}. CC -!- FUNCTION: [Protease 3C]: cleaves host DDX58/RIG-I and thus contributes CC to the inhibition of type I interferon production. Cleaves also host CC PABPC1 (By similarity). {ECO:0000250}. 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 (By similarity).

CC -!- SUBUNIT: Capsid protein VP1: Interacts with capsid protein VP0, and CC capsid protein VP3 to form heterotrimeric protomers. Five protomers CC subsequently associate to form pentamers which serve as building blocks CC for the capsid. Interacts with capsid protein VP4 in the mature capsid CC (By similarity). Interacts with host CD55 and FCGRT; these interactions CC promote virus attachment to the host cell and subsequent CC internalization (PubMed:7517044, PubMed:30808762).
