Abstract: Mitochondria and chloroplasts are semi-autonomous organelles harboring their own genomes. RNA editing is essential for the correct expression of organelle genes. The mostly identified RNA editing is cytidine (C)-to-uridine (U). Multiple editing factors have been reported to be involved in RNA C→U editing. The PPR-motifs array in PPR proteins specifically target editing sites, and the DYW domains in PPR-DYW proteins catalyze the deaminase in the C→U editing. This paper aims to review the recent advance of PPR proteins involved in RNA C→U editing, and to discuss the potential application value of synthetic PPR editing factors.

Key words: PPR proteins, RNA C→U editing, mitochondria, chloroplasts
