[ | [https://www.uniprot.org/uniprot/2B_TAV 2B_TAV] Acts as 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. Forms a homodimer to measure siRNA duplex in a length-preferencemode. Binds to both siRNA duplexes (19bp) and long siRNA duplexes (30bp).<ref>PMID:10329615</ref> <ref>PMID:8291242</ref> <ref>PMID:9010309</ref> | ||
