Abstract

Adenosine deaminases acting on RNA (ADAR) catalyze adenosine to inosine editing within double-stranded RNA (dsRNA) substrates. Inosine is read as a guanine by most cellular processes and therefore these changes create codons for a different amino acid, stop codons or even a new splice-site allowing protein diversity generated from a single gene. We review here the current structural and molecular knowledge on RNA editing by the ADAR family of protein. We focus especially on two types of nucleic acid binding domains present in ADARs, namely the dsRNA and Z-DNA binding domains.
