... deaminases that act on RNA (ADAR). ADARs are an evolutionarily conserved family of enzymes that convert adenosines to inosines within mRNA transcripts. Because inosine is read as guanosine during translation, RNA editing may lead to recoding during translation, resulting in proteins with altered fun ...

RNA silencing

RNA silencing (associated with the concept of post-transcriptional gene silencing or RNA interference) refers to a family of gene silencing effects by which the expression of one or more genes is downregulated or entirely suppressed by non-coding RNAs, particularly small RNAs. It may also refer to the introduction of a synthetic antisense RNA molecule used in scientific experiments on gene expression. RNA silencing may also be defined as sequence-specific regulation of gene expression triggered by double-stranded RNA (dsRNA). RNA silencing mechanisms are highly conserved in most eukaryotes. The most common and well-studied example is RNA interference (RNAi), in which endogenously expressed microRNA (miRNA) or exogenously derived small interfering RNA (siRNA) induces the degradation of complementary messenger RNA. Other classes of small RNA have been identified, including piwi-interacting RNA (piRNA) and its subspecies repeat associated small interfering RNA (rasiRNA).
