MEF7 - Plant Editosome Database - CNCB-NGDC

Summary

Editing Factor: MEF7
Synonym: MITOCHONDRIAL EDITING FACTOR 7
Description: Four of these RNA editing events in plant mitochondria specifically require the PPR protein MEF7, characterized by E and DYW extension domains; Five nucleotides are conserved between the four affected editing sites, but are not sufficient for specific recognition by MEF7 since they are also present at three other sites which are unaffected in the mutants
Protein Family: Pentatricopeptide repeat (PPR) protein
Subclass: DYW
Physical Interaction: NA
Construct Structure: PLS-E-DYW
Gene ID & Species: AT5G09950 (Arabidopsis thaliana)
Edited Gene(s): ccmB    cob    nad2    nad4L    nad4
Editing Type(s): C-to-U (28)
Publication(s): [1] Multiple PPR Protein Interactions Are Involved in the RNA Editing System in Arabidopsis Mitochondria and Plastids, Proc Natl Acad Sci U S A, 2017. [doi:10.1073/pnas.1705815114]
