CC -!- FUNCTION: [Helper component proteinase]: Required for aphid
CC transmission and also has proteolytic activity. Only cleaves a Gly-Gly
CC dipeptide at its own C-terminus. Interacts with virions and aphid
CC stylets. Acts as a suppressor of RNA-mediated gene silencing, also
CC known as post-transcriptional gene silencing (PTGS), a mechanism of
CC plant viral defense that limits the accumulation of viral RNAs. May
CC have RNA-binding activity. {ECO:0000250|UniProtKB:P04517}.
CC -!- FUNCTION: [Cytoplasmic inclusion protein]: Has helicase activity. It
CC may be involved in replication.
CC -!- FUNCTION: [6 kDa protein 1]: Indispensable for virus replication.
CC {ECO:0000250|UniProtKB:P13529}.
CC -!- FUNCTION: [6 kDa protein 2]: Indispensable for virus replication.
CC {ECO:0000250|UniProtKB:P09814}.
CC -!- FUNCTION: [Viral genome-linked protein]: Mediates the cap-independent,
CC EIF4E-dependent translation of viral genomic RNAs (PubMed:31712417).
CC Binds to the cap-binding site of host EIF4E and thus interferes with
CC the host EIF4E-dependent mRNA export and translation (PubMed:31712417).
CC VPg-RNA directly binds EIF4E and is a template for transcription
CC (PubMed:31712417). Also forms trimeric complexes with EIF4E-EIF4G,
CC which are templates for translation (PubMed:31712417).
CC {ECO:0000269|PubMed:31712417}.
CC -!- FUNCTION: [Nuclear inclusion protein A]: Has RNA-binding and
CC proteolytic activities. {ECO:0000250|UniProtKB:P04517}.
CC -!- FUNCTION: [Nuclear inclusion protein B]: An RNA-dependent RNA
CC polymerase that plays an essential role in the virus replication.
CC -!- FUNCTION: [Capsid protein]: Involved in aphid transmission, cell-to-
CC cell and systemis movement, encapsidation of the viral RNA and in the
CC regulation of viral RNA amplification. {ECO:0000250|UniProtKB:P04517}.
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=Hydrolyzes glutaminyl bonds, and activity is further
CC restricted by preferences for the amino acids in P6 - P1' that vary
CC with the species of potyvirus, e.g. Glu-Xaa-Xaa-Tyr-Xaa-Gln-|-(Ser or
CC Gly) for the enzyme from tobacco etch virus. The natural substrate is
CC the viral polyprotein, but other proteins and oligopeptides
CC containing the appropriate consensus sequence are also cleaved.;
CC EC=3.4.22.44; Evidence={ECO:0000250|UniProtKB:P04517};
CC -!- CATALYTIC ACTIVITY:
CC Reaction=Hydrolyzes a Gly-|-Gly bond at its own C-terminus, commonly in
CC the sequence -Tyr-Xaa-Val-Gly-|-Gly, in the processing of the
CC potyviral polyprotein.; EC=3.4.22.45;
CC Evidence={ECO:0000250|UniProtKB:P04517};
CC -!- SUBUNIT: [Viral genome-linked protein]: Interacts with host eIF4E
CC protein (via cap-binding region); this interaction mediates the
CC translation of the VPg-viral RNA conjugates (PubMed:31712417). Part of
CC a complex that comprises VPg, RNA, host EIF4E and EIF4G; this
CC interaction mediates the translation of the VPg-viral RNA conjugates
CC (PubMed:31712417). Interaction is possible in susceptible hosts but
CC impaired in resistant plants: the VPg of strain LYE84 interacts with
CC tomato eIF4E1 and eIF4E2 as well as with the Capsicum annuum eIF4E1
CC susceptible allele pvr2(+) but not with resistant alleles pvr2(1),
CC pvr2(2), pvr2(3), pvr2(4), pvr2(5), pvr2(6), pvr2(7), pvr2(8) and
CC pvr2(9), the VPg of strain SON41 interacts with C.annuum eIF4E1
CC susceptible alleles pvr2(+), pvr2(1), pvr2(2), pvr2(3) and pvr2(4) but
CC not with resistant alleles pvr2(5), pvr2(6), pvr2(7), pvr2(8) and
CC pvr2(9), the VPg of strain LYE90 interacts only with tomato eIF4E1
CC (PubMed:22242134, PubMed:18182024). {ECO:0000269|PubMed:18182024,
CC ECO:0000269|PubMed:22242134, ECO:0000269|PubMed:31712417}.
CC -!- SUBCELLULAR LOCATION: [6 kDa protein 1]: Host cytoplasmic vesicle.
CC Note=Probably colocalizes with 6K2-induced vesicles associated with
CC host chloroplasts. {ECO:0000250|UniProtKB:P13529}.
CC -!- SUBCELLULAR LOCATION: [6 kDa protein 2]: Host cytoplasmic vesicle
CC {ECO:0000250|UniProtKB:P09814}. Note=6K-induced vesicles associate with
CC host chloroplasts. {ECO:0000250|UniProtKB:P09814}.
CC -!- SUBCELLULAR LOCATION: [Viral genome-linked protein]: Host nucleus
CC {ECO:0000250|UniProtKB:P21231}. Note=Binds to host plant eIF4E proteins
CC in the host nucleus. {ECO:0000250|UniProtKB:P21231}.
CC -!- SUBCELLULAR LOCATION: [Capsid protein]: Virion {ECO:0000305}.
CC -!- ALTERNATIVE PRODUCTS:
CC Event=Ribosomal frameshifting; Named isoforms=2;
CC Name=Genome polyprotein;
CC IsoId=P18247-1; Sequence=Displayed;
CC Name=P3N-PIPO polyprotein;
CC IsoId=P0CJ93-1; Sequence=External;
CC -!- DOMAIN: [Helper component proteinase]: The N-terminus is involved in
CC interaction with stylets. The central part is involved in interaction
CC with virions and the C-terminus is involved in cell-to cell movement of
CC the virus.
CC -!- PTM: [Viral genome-linked protein]: VPg is uridylylated by the
CC polymerase and is covalently attached to the 5'-end of the genomic RNA.
CC This uridylylated form acts as a nucleotide-peptide primer for the
CC polymerase (By similarity). {ECO:0000250|UniProtKB:P09814}.
CC -!- PTM: [Genome polyprotein]: Potyviral RNA is expressed as two
CC polyproteins which undergo post-translational proteolytic processing.
CC Genome polyprotein is processed by NIa-pro, P1 and HC-pro proteinases
CC resulting in the production of at least ten individual proteins. P3N-
CC PIPO polyprotein is cleaved by P1 and HC-pro proteinases resulting in
CC the production of three individual proteins. The P1 proteinase and the
CC HC-pro cleave only their respective C-termini autocatalytically. 6K1 is
CC essential for proper proteolytic separation of P3 from CI (By
CC similarity). {ECO:0000250}.

CC and pvr2(4) but not plants containing alleles pvr2(5), pvr2(6),
