Protein Domain : RNA-binding protein B2 superfamily IPR037209

Type	Homologous_superfamily
Description	Protein B2 binds double-strand RNA (dsRNA) with high affinity and suppresses the host RNA silencing-based antiviral response. B2 is expressed by the insect Flock House virus (FHV) as a counter-defense mechanism against antiviral RNA silencing during infection. In vitro, B2 binds to dsRNA as a dimer and inhibits the cleavage of it by Dicer. B2 blocks cleavage of the FHV genome by Dicer and also the incorporation of FHV small interfering RNAs into the RNA-induced silencing complex [ ].
Short Name	RNA-bd_B2_sf
