Capsid protein VP1
Forms an icosahedral capsid of pseudo T=3 symmetry with capsid proteins VP2 and VP3 (By similarity).
The capsid is 300 Angstroms in diameter, composed of 60 copies of each capsid protein and enclosing the viral positive strand RNA genome (By similarity).
Capsid protein VP1 mainly forms the vertices of the capsid (By similarity).
Capsid protein VP1, together with VP2, interacts with host cell receptor SCARB2 to provide virion attachment to target host cells (PubMed:30531980).
This attachment induces virion internalization (By similarity).
After binding to its receptor, the capsid undergoes conformational changes (By similarity).
Capsid protein VP1 N-terminus (that contains an amphipathic alpha-helix) and capsid protein VP4 are externalized (By similarity).
Together, they shape a pore in the host membrane through which viral genome is translocated to host cell cytoplasm (By similarity).

Component of immature procapsids, which is cleaved into capsid proteins VP4 and VP2 after maturation (By similarity).
Allows the capsid to remain inactive before the maturation step (By similarity).
Allows the capsid to remain inactive before the maturation step (By similarity).
Protease 2A
Cysteine protease that cleaves viral polyprotein and specific host proteins (By similarity).
It is responsible for the autocatalytic cleavage between the P1 and P2 regions, which is the first cleavage occurring in the polyprotein (By similarity).
Cleaves also the host translation initiation factor EIF4G1, in order to shut down the capped cellular mRNA translation (By similarity).
Inhibits the host nucleus-cytoplasm protein and RNA trafficking by cleaving host members of the nuclear pores (By similarity).
Counteracts stress granule formation probably by antagonizing its assembly or promoting its dissassembly (By similarity).

Protein 2B
Plays an essential role in the virus replication cycle by acting as a viroporin. Creates a pore in the host reticulum endoplasmic and as a consequence releases Ca2+ in the cytoplasm of infected cell. In turn, high levels of cytoplasmic calcium may trigger membrane trafficking and transport of viral ER-associated proteins to viroplasms, sites of viral genome replication.
Protein 2C
Induces and associates with structural rearrangements of intracellular membranes. Displays RNA-binding, nucleotide binding and NTPase activities. May play a role in virion morphogenesis and viral RNA encapsidation by interacting with the capsid protein VP3.
Protein 3AB
Localizes the viral replication complex to the surface of membranous vesicles. Together with protein 3CD binds the Cis-Active RNA Element (CRE) which is involved in RNA synthesis initiation. Acts as a cofactor to stimulate the activity of 3D polymerase, maybe through a nucleid acid chaperone activity.
Protein 3A
Localizes the viral replication complex to the surface of membranous vesicles (By similarity).
It inhibits host cell endoplasmic reticulum-to-Golgi apparatus transport and causes the disassembly of the Golgi complex, possibly through GBF1 interaction (By similarity).
This would result in depletion of MHC, trail receptors and IFN receptors at the host cell surface (By similarity).
Plays an essential role in viral RNA replication by recruiting ACBD3 and PI4KB at the viral replication sites, thereby allowing the formation of the rearranged membranous structures where viral replication takes place (Probable)

Viral protein genome-linked
Acts as a primer for viral RNA replication and remains covalently bound to viral genomic RNA. VPg is uridylylated prior to priming replication into VPg-pUpU (By similarity).
The oriI viral genomic sequence may act as a template for this. The VPg-pUpU is then used as primer on the genomic RNA poly(A) by the RNA-dependent RNA polymerase to replicate the viral genome (By similarity).
Following genome release from the infecting virion in the cytoplasm, the VPg-RNA linkage is probably removed by host TDP2 (By similarity).
During the late stage of the replication cycle, host TDP2 is excluded from sites of viral RNA synthesis and encapsidation, allowing for the generation of progeny virions (By similarity).

Protein 3CD
Involved in the viral replication complex and viral polypeptide maturation. It exhibits protease activity with a specificity and catalytic efficiency that is different from protease 3C. Protein 3CD lacks polymerase activity. Protein 3CD binds to the 5'UTR of the viral genome.
Protease 3C
Major viral protease that mediates proteolytic processing of the polyprotein (By similarity).
Cleaves host EIF5B, contributing to host translation shutoff (By similarity).
Cleaves also host PABPC1, contributing to host translation shutoff (By similarity).
Disassembles host cytoplasmic stress granules by cleaving host G3BP1, although this effect is less prononced than the inhibition induced by protease 2A (By similarity).
Cleaves host RIGI and thus contributes to the inhibition of type I interferon production (By similarity).
Cleaves host IRF7 and thus contributes to the inhibition of type I interferon production (By similarity).
Cleaves host HNRNPA1 thereby increasing the translation of apoptosis protease activating factor APAF1, leading to apoptosis of the host cell (By similarity).
Cleaves host NLRP1, triggers host N-glycine-mediated degradation of the autoinhibitory NLRP1 N-terminal fragment (By similarity).

RNA-directed RNA polymerase
Replicates the viral genomic RNA on the surface of intracellular membranes. May form linear arrays of subunits that propagate along a strong head-to-tail interaction called interface-I. Covalently attaches UMP to a tyrosine of VPg, which is used to prime RNA synthesis. The positive stranded RNA genome is first replicated at virus induced membranous vesicles, creating a dsRNA genomic replication form. This dsRNA is then used as template to synthesize positive stranded RNA genomes. ss+RNA genomes are either translated, replicated or encapsidated.

Post-translational modification
Genome polyprotein
Specific enzymatic cleavages in vivo by the viral proteases yield processing intermediates and the mature proteins.
Capsid protein VP0
Myristoylation is required for the formation of pentamers during virus assembly. Further assembly of 12 pentamers and a molecule of genomic RNA generates the provirion.
Capsid protein VP0
During virion maturation, immature virions are rendered infectious following cleavage of VP0 into VP4 and VP2. This maturation seems to be an autocatalytic event triggered by the presence of RNA in the capsid and it is followed by a conformational change infectious virion.
Capsid protein VP4
Myristoylation is required during RNA encapsidation and formation of the mature virus particle.
Viral protein genome-linked
VPg is uridylylated by the polymerase into VPg-pUpU. This acts as a nucleotide-peptide primer for the genomic RNA replication.
