MEF22 - Plant Editosome Database - CNCB-NGDC

Summary

Editing Factor: MEF22
Synonym: MITOCHONDRIAL EDITING FACTOR 22
Description: Homozygous mutants of the five genes MEF18-MEF22 display no gross disturbance in their growth or development patterns, suggesting that the editing sites affected are not crucial at least in the greenhouse; These results show that a considerable percentage of the E-PPR proteins are involved in the functional processing of site-specific RNA editing in plant mitochondria
Protein Family: Pentatricopeptide repeat (PPR) protein
Subclass: DYW
Physical Interaction: NA
Construct Structure: PLS-E-DYW
Gene ID & Species: AT3G12770 (Arabidopsis thaliana)
Edited Gene(s): nad3
Editing Type(s): C-to-U (6)
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]
