Involved in organellar RNA editing. Required for the processing of numerous RNA editing sites in mitochondria and plastids (PubMed:22566615, PubMed:23818871). Binds to the plastid RARE1 factor, a pentatricopeptide repeat-containing protein involved in RNA editing (PubMed:22566615). Interacts with protoporphyrinogen oxidase 1 PPOX1 (PubMed:24497494). Interacts with PCMP-H52/MEF10 (PubMed:23288601). Homodimer and heterodimers with MORF1/RIP8, MORF2/RIP2, MORF3/RIP3, MORF4/RIP4, MORF5/RIP5, MORF6/RIP6 and MORF7/RIP7 (PubMed:25583991). Interacts with RBG3/ORRM3 (PubMed:25800738). Interacts with PCMP-A2/PMD1 (PubMed:26123918). Interacts with ORRM1 and VAT3/OZ1 (PubMed:25768119). Interacts with PCMP-H13/MEF35 (PubMed:26470017). Interacts with RBG5/ORRM4 (PubMed:26578708). Interacts with ORRM6 (PubMed:28213559). Dual targeting to mitochondria and chloroplasts. Dwarf plants. Belongs to the MORF family.
