CC -!- FUNCTION: Strong activator of the late viral genes promoters. Enhances
CC the expression of the capsid protein and nuclear shuttle protein. Acts
CC as a suppressor of RNA-mediated gene silencing, also known as post-
CC transcriptional gene silencing (PTGS), a mechanism of plant viral
CC defense that limits the accumulation of viral RNAs. Suppresses the host
CC RNA silencing by inhibiting adenosine kinase 2 (ADK2), a kinase
CC involved in a general methylation pathway. Also suppresses the host
CC basal defense by interacting with and inhibiting SNF1 kinase, a key
CC regulator of cell metabolism implicated in innate antiviral defense.
CC Determines pathogenicity (By similarity). {ECO:0000250}.
CC -!- SUBUNIT: Monomer. Homodimer. Homooligomer. Self-interaction correlates
CC with nuclear localization and efficient activation of transcription.
CC Monomers suppress local silencing by interacting with and inactivating
CC host adenosine kinase 2 (ADK2) in the cytoplasm. Interacts with and
CC inhibits host SNF1 kinase. Binds to ssDNA (By similarity).
CC {ECO:0000250}.
CC -!- SUBCELLULAR LOCATION: Host nucleus {ECO:0000250}. Host cytoplasm
CC {ECO:0000250}. Note=The phosphorylated form appears to accumulate
CC almost exclusively in the nucleus, whereas the non-phosphorylated form
CC is found in both nucleus and cytoplasm. {ECO:0000250}.
CC -!- DOMAIN: The zinc finger and the transactivation region are involved in
CC PTGS suppression. {ECO:0000250}.
CC -!- PTM: Phosphorylated. {ECO:0000250}.
CC -!- SIMILARITY: Belongs to the geminiviridae transcriptional activator
CC protein family. {ECO:0000305}.
