MEF14 - Plant Editosome Database - CNCB-NGDC

Summary

Editing Factor: MEF14
Synonym: MITOCHONDRIAL EDITING FACTOR 14
Description: A T-DNA insertion in the MEF14 gene abolishes detectable editing at the matR-1895 site; Lack of RNA editing at the matR-1895 site does not alter the level of mature and precursor nad1 mRNA molecules; Such RNA editing mutants can be used to analyse the function of genes like this maturase related reading frame in plant mitochondria
Protein Family: Pentatricopeptide repeat (PPR) protein
Subclass: DYW
Physical Interaction: NA
Construct Structure: PLS-E-E+-DYW
Gene ID & Species: AT3G26780 (Arabidopsis thaliana)
Edited Gene(s): matR
Editing Type(s): C-to-U (7)
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]
