CC   -!- FUNCTION: Viral suppressor of RNA silencing which binds specifically to
CC       silencing RNAs (siRNAs). Acts as a molecular caliper to specifically
CC       select siRNAs based on the length of the duplex region of the RNA (By
CC       similarity). {ECO:0000250}.
CC   -!- SUBUNIT: Homodimer. {ECO:0000250}.
CC   -!- SIMILARITY: Belongs to the tombusvirus protein p19 family.
CC       {ECO:0000305}.
