Identification of new pentatricopeptide repeat proteins, MREF1 and 2, involved in mitochondrial RNA editing, using computational target RNA prediction.

ABSTRACT: C-to-U RNA editing has been widely observed in mitochondrial and plastid RNAs in plants. The editing sites are known to be recognized by pentatricopeptide repeat (PPR) proteins, which belong to one of the largest protein families in vascular plants. PPR proteins are sequence-specific RNA-binding proteins that participate in various steps of organelle RNA metabolism, such as cleavage, stabilization, splicing, translation, and editing. Elucidating the underlying mechanisms of sequence-specific RNA recognition by PPR proteins expanded our understanding of the role of PPR proteins in plant organellar RNA editing and enabled the computational prediction of target RNA-editing sites for PPR proteins of interest. Combining computational prediction and experimental verification, we identified three
