MEF19 - Plant Editosome Database

Editing Factor:	MEF19
Synonym:	MITOCHONDRIAL EDITING FACTOR 19
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:	E
Physical Interaction:	NA
Construct Structure:	PLS-E
Gene ID & Species:	AT3G05240 (Arabidopsis thaliana)
Edited Gene(s):	ccmB
Editing Type(s):	C-to-U (5)
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] [2] Reverse Genetic Screening Identifies Five E-class PPR Proteins Involved in RNA Editing in Mitochondria of Arabidopsis thaliana, The Journal of Biological Chemistry, 2010.
