Critical review on engineering deaminases for site-directed RNA editing

The game-changing role of CRISPR/Cas for genome editing draw interest to programmable RNA-guided tools in general. Currently, we see a wave of papers pioneering the CRISPR/Cas system for RNA targeting, and applying them for site-directed RNA editing. Here, we exemplarily compare three recent RNA editing strategies that rely on three distinct RNA targeting mechanisms. We conclude that the CRISPR/Cas system seems not generally superior to other...
