Fig. 3From: RNA modifications in brain tumorigenesisThe hydrolytic deamination of adenosine is catalyzed by ADAR enzymes, resulting in the formation of inosine. Due to structural similarities between inosine and guanosine, the translational machinery reads the nucleoside as the latter, potentially resulting in changes to codon sequences or the addition/removal of splice sites. The A-to-I modification can also serve to direct alternative splicing to create oncogenic protein isoforms that promote glioma progressionBack to article page
