CC -!- FUNCTION: [Leader protein]: Forms a complex with host RAN and probably
CC binds to exportins carrying activated MAPK in order to mediate the
CC hyperphosphorylation of host Phe/Gly containing nuclear pore proteins
CC (Nups) resulting in cessation of active nucleocytoplasmic transport (By
CC similarity). Proteins with NLS signals fail to import, cellular mRNAs
CC fail to export, and some proteins small enough for diffusion are not
CC retained anymore (efflux) (By similarity). The resulting inhibition of
CC cellular protein synthesis serves to ensure maximal viral gene
CC expression and to evade host immune response (By similarity). The
CC leader protein also inhibits host interferon regulatory factor 3 (IRF3)
CC dimerization, thereby blocking the transcriptional activation of IFN
CC genes (By similarity). Binds to host RNase L thereby preventing its
CC activation by 2'-5' oligoadenylates in order to counteract the
CC antiviral interferon-inducible OAS/RNase L pathway (By similarity).
CC {ECO:0000250|UniProtKB:P13899, ECO:0000250|UniProtKB:Q66765}.
CC -!- FUNCTION: [Capsid protein VP1]: Forms an icosahedral capsid of pseudo
CC T=3 symmetry with capsid proteins VP2 and VP3. Together they form an
CC icosahedral capsid composed of 60 copies of each VP1, VP2, and VP3,
CC with a diameter of approximately 300 Angstroms.VP4 lies on the inner
CC surface of the protein shell formed by VP1, VP2 and VP3. All the three
CC latter proteins contain a beta-sheet structure called beta-barrel jelly
CC roll. VP1 is situated at the 12 fivefold axes, whereas VP2 and VP3 are
CC located at the quasi-sixfold axes. {ECO:0000250|UniProtKB:C0MHL9}.
CC -!- FUNCTION: [Capsid protein VP2]: Forms an icosahedral capsid of pseudo
CC T=3 symmetry with capsid proteins VP2 and VP3. Together they form an
CC icosahedral capsid composed of 60 copies of each VP1, VP2, and VP3,
CC with a diameter of approximately 300 Angstroms.VP4 lies on the inner
CC surface of the protein shell formed by VP1, VP2 and VP3. All the three
CC latter proteins contain a beta-sheet structure called beta-barrel jelly
CC roll. VP1 is situated at the 12 fivefold axes, whereas VP2 and VP3 are
CC located at the quasi-sixfold axes. {ECO:0000250|UniProtKB:C0MHL9}.
CC -!- FUNCTION: [Capsid protein VP3]: Forms an icosahedral capsid of pseudo
CC T=3 symmetry with capsid proteins VP2 and VP3. Together they form an
CC icosahedral capsid composed of 60 copies of each VP1, VP2, and VP3,
CC with a diameter of approximately 300 Angstroms.VP4 lies on the inner
CC surface of the protein shell formed by VP1, VP2 and VP3. All the three
CC latter proteins contain a beta-sheet structure called beta-barrel jelly
CC roll. VP1 is situated at the 12 fivefold axes, whereas VP2 and VP3 are
CC located at the quasi-sixfold axes. {ECO:0000250|UniProtKB:C0MHL9}.
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). After
CC genome has been released, the channel shrinks (By similarity).
CC {ECO:0000250|UniProtKB:C0MHL9, ECO:0000250|UniProtKB:P03300}.
CC -!- FUNCTION: [Capsid protein VP0]: VP0 precursor is a component of
CC immature procapsids. {ECO:0000250|UniProtKB:P08617}.
CC -!- FUNCTION: [Protein 2A]: Involved in host translation shutoff by
CC inhibiting cap-dependent mRNA translation (By similarity). Nuclear
CC localization is required for this function (By similarity). The
CC resulting inhibition of cellular protein synthesis serves to ensure
CC maximal viral gene expression and to evade host immune response (By
CC similarity). Inhibits the phosphorylation of the leader protein (By
CC similarity). Binds to the RNA stem-loop essential for the ribosomal
CC frameshift event and trans-activates the production of protein 2B* (By
CC similarity). {ECO:0000250|UniProtKB:P12296,
CC ECO:0000250|UniProtKB:Q66765}.

CC increase in membrane permeability. {ECO:0000250}.
CC -!- FUNCTION: [Protein 2C]: Associates with and induces structural
CC rearrangements of intracellular membranes (Probable). It displays RNA-
CC binding, nucleotide binding and NTPase activities (By similarity).
CC {ECO:0000250|UniProtKB:P03305, ECO:0000305|PubMed:20471424}.
CC -!- FUNCTION: [Protein 3A]: Serves as membrane anchor via its hydrophobic
CC domain. {ECO:0000250}.
CC -!- FUNCTION: [VPg]: Forms a primer, VPg-pU, which is utilized by the
CC polymerase for the initiation of RNA chains.
CC {ECO:0000250|UniProtKB:P03304}.
CC -!- FUNCTION: [Protease 3C]: Cysteine protease that generates mature viral
CC proteins from the precursor polyprotein (By similarity). In addition to
CC its proteolytic activity, it binds to viral RNA, and thus influences
CC viral genome replication. RNA and substrate cooperatively bind to the
CC protease. Cleaves host PABP1, this cleavage is important for viral
CC replication (By similarity). {ECO:0000250|UniProtKB:P03304,
CC ECO:0000250|UniProtKB:P12296}.
CC -!- FUNCTION: [RNA-directed RNA polymerase]: Replicates the genomic and
CC antigenomic RNAs by recognizing replications specific signals (By
CC similarity). Performs VPg uridylylation (By similarity).

CC -!- PTM: [Capsid protein VP4]: Myristoylation is required during RNA
CC encapsidation and formation of the mature virus particle.
CC {ECO:0000250|UniProtKB:Q66282}.
CC -!- MISCELLANEOUS: Persistent strains of Theiler's virus (e.g. DA, TO,
