RN [2] RP SEQUENCE REVISION. RA Jeske H.; RL Submitted (NOV-2003) to the EMBL/GenBank/DDBJ databases. 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}.
