Only cleaves a Gly-Gly dipeptide at its own C-terminus. Interacts with virions and aphid stylets. Acts as a suppressor of RNA-mediated gene silencing, also known as post-transcriptional gene silencing (PTGS), a mechanism of plant viral defense that limits the accumulation of viral RNAs. May have RNA-binding activity.<ref>PMID:9880030</ref> <ref>PMID:11414807</ref> Cytoplasmic inclusion protein: has helicase activity. It may be involved in replication.<ref>PMID:9880030</ref> <ref>PMID:11414807</ref> Both 6K peptides are indispensable for virus replication (By similarity).<ref>PMID:9880030</ref> <ref>PMID:11414807</ref> Nuclear inclusion protein A: has RNA-binding and proteolytic activities.<ref>PMID:9880030</ref> <ref>PMID:11414807</ref> | ||
