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, together with VP2, interacts with
CC host cell receptor SCARB2 to provide virion attachment to target host
CC cells (PubMed:30531980). This attachment induces virion internalization
CC (By similarity). After binding to its receptor, the capsid undergoes
CC conformational changes (By similarity). Capsid protein VP1 N-terminus
CC (that contains an amphipathic alpha-helix) and capsid protein VP4 are
CC externalized (By similarity). Together, they shape a pore in the host
CC membrane through which viral genome is translocated to host cell
CC cytoplasm (By similarity). {ECO:0000250|UniProtKB:P03300,
CC ECO:0000269|PubMed:30531980}.
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). Capsid protein VP2, together with VP1, interacts with host
CC cell receptor SCARB2 to provide virion attachment to target host cells
CC (PubMed:30531980). {ECO:0000250|UniProtKB:P03300,
CC ECO:0000269|PubMed:30531980}.
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 (By
CC similarity). Counteracts stress granule formation probably by
CC antagonizing its assembly or promoting its dissassembly (By
CC similarity). Cleaves and inhibits host IFIH1/MDA5, thereby inhibiting
CC the type-I IFN production and the establishment of the antiviral state
CC (By similarity). Cleaves and inhibits host MAVS, thereby inhibiting the
CC type-I IFN production and the establishment of the antiviral state (By
CC similarity). {ECO:0000250|UniProtKB:P03300,
CC ECO:0000250|UniProtKB:Q66478}.
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 (Probable). {ECO:0000250|UniProtKB:P03300,
CC ECO:0000305|PubMed:31381608}.
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 Disassembles host cytoplasmic stress granules by cleaving host G3BP1,
CC although this effect is less prononced than the inhibition induced by
CC protease 2A (By similarity). Cleaves host DDX58/RIG-I and thus
CC contributes to the inhibition of type I interferon production (By
CC similarity). Cleaves host IRF7 and thus contributes to the inhibition
CC of type I interferon production (By similarity). Cleaves host HNRNPA1
CC thereby increasing the translation of apoptosis protease activating
CC factor APAF1, leading to apoptosis of the host cell (By similarity).
CC Cleaves host NLRP1, triggers host N-glycine-mediated degradation of the
CC autoinhibitory NLRP1 N-terminal fragment (By similarity).
CC {ECO:0000250|UniProtKB:P03300, ECO:0000250|UniProtKB:P03303,
CC ECO:0000250|UniProtKB:Q66478}.
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}.
