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