CC -!- FUNCTION: NTPase presumably plays a role in replication. {ECO:0000250}.
CC -!- FUNCTION: Viral genome-linked protein is covalently linked to the 5'-
CC end of the positive-strand, negative-strand genomic RNAs and subgenomic
CC RNA. Acts as a genome-linked replication primer. May recruit ribosome
CC to viral RNA thereby promoting viral proteins translation (By
CC similarity). {ECO:0000250}.
CC -!- FUNCTION: 3C-like protease processes the polyprotein: 3CLpro-RdRp (p72)
CC is first released by autocleavage, then all other proteins are cleaved.
CC {ECO:0000250}.
CC -!- FUNCTION: RNA-directed RNA polymerase replicates genomic and
CC antigenomic RNA by recognizing replications specific signals.
CC Transcribes also a subgenomic mRNA by initiating RNA synthesis
CC internally on antigenomic RNA. This sgRNA codes for structural
CC proteins. Catalyzes the covalent attachment VPg with viral RNAs (By
CC similarity). {ECO:0000255|PROSITE-ProRule:PRU00539}.
CC -!- FUNCTION: Capsid protein VP60 self assembles to form an icosahedral
CC capsid with a T=3 symmetry, about 35 nm in diameter, and consisting of
CC 180 capsid proteins. A smaller form of capsid with a diameter of 23 nm
CC might be capsid proteins assembled as icosahedron with T=1 symmetry.
CC The capsid encapsulate VP2 proteins and genomic or subgenomic RNA.
CC Attaches virion to target cells by binding histo-blood group antigens,
CC inducing endocytosis of the viral particle. Acidification of the
CC endosome induces conformational change of capsid protein thereby
CC injecting virus genomic RNA into host cytoplasm (By similarity).
CC {ECO:0000250}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=a ribonucleoside 5'-triphosphate + H2O = a ribonucleoside 5'-
CC diphosphate + H(+) + phosphate; Xref=Rhea:RHEA:23680,
CC ChEBI:CHEBI:15377, ChEBI:CHEBI:15378, ChEBI:CHEBI:43474,
CC ChEBI:CHEBI:57930, ChEBI:CHEBI:61557; EC=3.6.1.15;
CC -!- CATALYTIC ACTIVITY:
CC Reaction=a ribonucleoside 5'-triphosphate + RNA(n) = diphosphate +
CC RNA(n+1); Xref=Rhea:RHEA:21248, Rhea:RHEA-COMP:14527, Rhea:RHEA-
CC COMP:17342, ChEBI:CHEBI:33019, ChEBI:CHEBI:61557, ChEBI:CHEBI:140395;
CC EC=2.7.7.48; Evidence={ECO:0000255|PROSITE-ProRule:PRU00539};
CC -!- CATALYTIC ACTIVITY:
CC Reaction=Endopeptidase with a preference for cleavage when the P1
CC position is occupied by Glu-|-Xaa and the P1' position is occupied by
CC Gly-|-Yaa.; EC=3.4.22.66; Evidence={ECO:0000255|PROSITE-
CC ProRule:PRU01242};
CC -!- SUBUNIT: Binds to histo-blood group antigens at surface of target
CC cells. {ECO:0000250}.
CC -!- SUBCELLULAR LOCATION: [Capsid protein VP60]: Virion. Host cytoplasm
CC {ECO:0000250}.
CC -!- ALTERNATIVE PRODUCTS:
CC Event=Alternative promoter usage; Named isoforms=2;
CC Name=Genome polyprotein;
CC IsoId=Q86117-1; Sequence=Displayed;
CC Name=Subgenomic capsid protein VP60; Synonyms=VP1;
CC IsoId=Q86117-2; Sequence=VSP_034382;
CC -!- PTM: Specific enzymatic cleavages by its own cysteine protease yield
CC mature proteins. The protease cleaves itself from the nascent
CC polyprotein autocatalytically. Precursor p41 can be cleaved by viral
CC 3CLpro into protein p19 and VPg, or cleaved by host protease into
CC protein p23/2 and protein p18 (By similarity). {ECO:0000250}.
CC -!- PTM: VPg is uridylylated by the polymerase and is covalently attached
CC to the 5'-end of the polyadenylated genomic and subgenomic RNAs. This
CC uridylylated form acts as a nucleotide-peptide primer for the
CC polymerase (By similarity). {ECO:0000250}.
CC -!- MISCELLANEOUS: Two different RNAs lead the expression of the capsid
CC protein. One arises from the cleavage of the polyprotein translated
CC from the genomic RNA and the other from the translation of a subgenomic
CC RNA derived from the (-)RNA template. Capsid protein expressed from the
CC subgenomic mRNA is produced in much larger amounts than the cleaved one
CC (By similarity). {ECO:0000250}.
CC -!- MISCELLANEOUS: [Isoform Genome polyprotein]: Produced from the genomic
CC RNA.
CC -!- MISCELLANEOUS: [Isoform Subgenomic capsid protein VP60]: Produced from
CC the subgenomic RNA. {ECO:0000305}.
