Virol. 76:7694-7704(2002). CC -!- FUNCTION: Capsid protein VP1: Forms an icosahedral capsid of CC pseudo T=3 symmetry with capsid proteins VP2 and VP3. The capsid CC is 300 Angstroms in diameter, composed of 60 copies of each capsid CC protein and enclosing the viral positive strand RNA genome. Capsid CC protein VP1 mainly forms the vertices of the capsid. Capsid CC protein VP1 interacts with host CD55 to provide virion attachment CC to target host cells. This attachment induces virion CC internalization. Tyrosine kinases are probably involved in the CC entry process. After binding to its receptor, the capsid undergoes CC conformational changes. Capsid protein VP1 N-terminus (that CC contains an amphipathic alpha-helix) and capsid protein VP4 are CC 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 CC similarity). {ECO:0000250}. CC -!- FUNCTION: Capsid protein VP2: Forms an icosahedral capsid of CC pseudo T=3 symmetry with capsid proteins VP2 and VP3. The capsid CC is 300 Angstroms in diameter, composed of 60 copies of each capsid CC protein and enclosing the viral positive strand RNA genome (By CC similarity). {ECO:0000250}. CC -!- FUNCTION: Capsid protein VP3: Forms an icosahedral capsid of CC pseudo T=3 symmetry with capsid proteins VP2 and VP3. The capsid CC is 300 Angstroms in diameter, composed of 60 copies of each capsid CC protein and enclosing the viral positive strand RNA genome (By CC similarity). {ECO:0000250}. CC -!- FUNCTION: Capsid protein VP4: Lies on the inner surface of the CC capsid shell. After binding to the host receptor, the capsid CC undergoes conformational changes. Capsid protein VP4 is released, CC Capsid protein VP1 N-terminus is externalized, and together, they CC shape a pore in the host membrane through which the viral genome CC is translocated into the host cell cytoplasm. After genome has CC been released, the channel shrinks (By similarity). {ECO:0000250}. CC -!- FUNCTION: Capsid protein VP0: Component of immature procapsids, CC which is cleaved into capsid proteins VP4 and VP2 after CC maturation. Allows the capsid to remain inactive before the CC maturation step (By similarity). {ECO:0000250}. CC -!- FUNCTION: Protein 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 CC in the polyprotein. Cleaves also the host translation initiation CC factor EIF4G1, in order to shut down the capped cellular mRNA CC translation. Inhibits the host nucleus-cytoplasm protein and RNA CC trafficking by cleaving host members of the nuclear pores (By CC similarity). {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 CC host reticulum endoplasmic and as a consequence releases Ca2+ in CC the cytoplasm of infected cell. In turn, high levels of CC cytoplasmic calcium may trigger membrane trafficking and transport CC of viral ER-associated proteins to viroplasms, sites of viral CC genome replication (By 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 CC virion morphogenesis and viral RNA encapsidation by interacting CC with the capsid protein VP3 (By similarity). {ECO:0000250}. CC -!- FUNCTION: Protein 3AB: Localizes the viral replication complex to CC the surface of membranous vesicles. Together with protein 3CD CC binds the Cis-Active RNA Element (CRE) which is involved in RNA CC synthesis initiation. Acts as a cofactor to stimulate the activity CC of 3D polymerase, maybe through a nucleid acid chaperone activity CC (By similarity). {ECO:0000250}. CC -!- FUNCTION: Protein 3A: Localizes the viral replication complex to CC the surface of membranous vesicles. It inhibits host cell CC endoplasmic reticulum-to-Golgi apparatus transport and causes the CC dissassembly of the Golgi complex, possibly through GBF1 CC interaction. This would result in depletion of MHC, trail CC receptors and IFN receptors at the host cell surface (By CC similarity). {ECO:0000250}. CC -!- FUNCTION: Viral protein genome-linked: acts as a primer for viral CC RNA replication and remains covalently bound to viral genomic RNA. CC VPg is uridylylated prior to priming replication into VPg-pUpU. CC The oriI viral genomic sequence may act as a template for this. CC 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. CC VPg may be removed in the cytoplasm by an unknown enzyme termed CC "unlinkase". VPg is not cleaved off virion genomes because CC replicated genomic RNA are encapsidated at the site of replication CC (By similarity). {ECO:0000250}. CC -!- FUNCTION: Protein 3CD: Is involved in the viral replication CC complex and viral polypeptide maturation. It exhibits protease CC activity with a specificity and catalytic efficiency that is CC different from protease 3C. Protein 3CD lacks polymerase activity. CC The 3C domain in the context of protein 3CD may have an RNA CC binding activity (By similarity). {ECO:0000250}. CC -!- FUNCTION: Protease 3C: cleaves host DDX58/RIG-I and thus CC contributes to the inhibition of type I interferon production. CC Cleaves also host PABPC1 (By similarity). {ECO:0000250}. CC -!- FUNCTION: RNA-directed RNA polymerase: Replicates the viral CC genomic RNA on the surface of intracellular membranes. May form CC linear arrays of subunits that propagate along a strong head-to- CC tail interaction called interface-I. Covalently attaches UMP to a CC tyrosine of VPg, which is used to prime RNA synthesis. The CC positive stranded RNA genome is first replicated at virus induced CC membranous vesicles, creating a dsRNA genomic replication form. CC This dsRNA is then used as template to synthesize positive CC stranded RNA genomes. ss(+)RNA genomes are either translated, CC replicated or encapsidated (By similarity). {ECO:0000255|PROSITE- CC ProRule:PRU00539}.

CC -!- SUBUNIT: Capsid protein VP1: Interacts with capsid protein VP0, CC and capsid protein VP3 to form heterotrimeric protomers. Five CC protomers subsequently associate to form pentamers which serve as CC building blocks for the capsid. Interacts with capsid protein VP4 CC in the mature capsid (By similarity).
