Description: MEF10 is a trans-factor required specifically for the C to U editing of site nad2-842; The MEF10 protein interacts with multiple organellar RNA editing factor 8 (MORF8) but not with other mitochondrial MORF proteins in yeast two hybrid assays
Protein Family: Pentatricopeptide repeat (PPR) protein
Subclass: DYW
Physical Interaction: MORF8
Construct Structure: PLS-E-E+-DYW
Gene ID & Species: AT3G11460 (Arabidopsis thaliana)
Edited Gene(s): nad2
Editing Type(s): C-to-U (6)
