Function
POLG_TUMVJ Capsid protein: involved in aphid transmission, cell-to-cell and systemis movement, encapsidation of the viral RNA and in the regulation of viral RNA amplification. Nuclear inclusion protein B: a RNA-dependent RNA polymerase that plays an essential role in the virus replication. Helper component proteinase: required for aphid transmission and also has proteolytic activity. 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 (By similarity). Cytoplasmic inclusion protein: has helicase activity. It may be involved in replication (By similarity). Both 6K peptides are indispensable for virus replication (By similarity). Nuclear inclusion protein A: has RNA-binding and proteolytic activities.
