ID A0A067XIY5_9POTV Unreviewed; 3219 AA. AC A0A067XIY5; DT 01-OCT-2014, integrated into UniProtKB/TrEMBL. DT 01-OCT-2014, sequence version 1. DT 03-AUG-2022, entry version 44. DE RecName: Full=Genome polyprotein {ECO:0000256|ARBA:ARBA00020107}; OS Watermelon mosaic virus. OC Viruses; Riboviria; Orthornavirae; Pisuviricota; Stelpaviricetes; OC Patatavirales; Potyviridae; Potyvirus. OX NCBI_TaxID=146500 {ECO:0000313|EMBL:AGE83528.1}; RN [1] {ECO:0000313|EMBL:AGE83528.1} RP NUCLEOTIDE SEQUENCE. RC STRAIN=WMV-ShanXi {ECO:0000313|EMBL:AGE83528.1}; RA Lei Z., Hao X., Wu Y.; RT "Complete genomic sequence analyses of Watermelon mosaic virus isolates RT from China."; RL Submitted (MAY-2012) to the EMBL/GenBank/DDBJ databases. CC -!- FUNCTION: An RNA-dependent RNA polymerase that plays an essential role CC in the virus replication. {ECO:0000256|ARBA:ARBA00029404}. CC -!- FUNCTION: Both 6K peptides are indispensable for virus replication. CC {ECO:0000256|ARBA:ARBA00002011}. CC -!- FUNCTION: Has RNA-binding and proteolytic activities. CC {ECO:0000256|ARBA:ARBA00029399}. CC -!- FUNCTION: Has helicase activity. It may be involved in replication. CC {ECO:0000256|ARBA:ARBA00029422}. CC -!- FUNCTION: Involved in aphid transmission, cell-to-cell and systemis CC movement, encapsidation of the viral RNA and in the regulation of viral CC RNA amplification. {ECO:0000256|ARBA:ARBA00029405}. CC -!- FUNCTION: Recruits the host translation initiation complex for viral CC genome translation by binding to host plant eIF4E/eIF(iso)4E and CC eIF4G/eIF(iso)4G proteins. {ECO:0000256|ARBA:ARBA00029412}. CC -!- FUNCTION: Required for aphid transmission and also has proteolytic CC activity. Only cleaves a Gly-Gly dipeptide at its own C-terminus. CC Interacts with virions and aphid stylets. Acts as a suppressor of RNA- CC mediated gene silencing, also known as post-transcriptional gene CC silencing (PTGS), a mechanism of plant viral defense that limits the CC accumulation of viral RNAs. May have RNA-binding activity. CC {ECO:0000256|ARBA:ARBA00029420}. 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:0000256|ARBA:ARBA00001848}; 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:0000256|ARBA:ARBA00000785}; CC -!- SUBCELLULAR LOCATION: Host nucleus {ECO:0000256|ARBA:ARBA00004147}. CC Nucleus {ECO:0000256|ARBA:ARBA00004123}. Virion CC {ECO:0000256|ARBA:ARBA00004328}. CC -!- SIMILARITY: Belongs to the potyviridae genome polyprotein family. CC {ECO:0000256|ARBA:ARBA00006064, ECO:0000256|RuleBase:RU003351}.
