LPA66 - Plant Editosome Database - CNCB-NGDC

Summary

Editing Factor: LPA66
Synonym: LOW PSII ACCUMULATION 66
Description: The assembly of newly synthesized proteins into PSII occurs in the lpa66 mutant but with reduced efficiency compared with the wild type; LPA66 is specifically required for editing the psbF transcripts in Arabidopsis, and the amino acid alternation due to lack of editing strongly affects the efficiency of the assembly of PSII complexes
Protein Family: Pentatricopeptide repeat (PPR) protein
Subclass: DYW
Physical Interaction: NA
Construct Structure: PLS-E-DYW
Gene ID & Species: AT5G48910 (Arabidopsis thaliana)
Edited Gene(s): psbF
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]
