Improving site-directed RNA editing by screening RNA editing
... Recoding genetic information through RNA editing is a process catalyzed by adenosine 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 ed ...
