Keyword Suppressor of RNA silencing

UniProtKB (5,863) rdf/xml obo
DefinitionProtein which suppresses host RNA-mediated gene silencing. The most common form of RNA-mediated gene silencing is RNA interference (RNAi), a sequence-specific RNA-degradation mechanism that operates as a natural antiviral system in plants and invertebrates cells. RNAi is mediated by small interfering RNAs (siRNA) of about 21- to 25-nt that target homologous RNAs for destruction. RNA silencing by endogenous micro-RNAs (miRNAs) may also play a role in the antiviral defences of mammals. miRNAs differ from siRNAs in that they generally base pair imperfectly with target RNAs and inhibit their translation by an unknown mechanism.
