PPR_45 - Plant Editosome Database - CNCB-NGDC

Summary

Editing Factor: PPR_45
Synonym: Phypa_156474
Description: Knockdown of the PpPPR_45 gene reduced the extent of RNA editing at the chloroplast rps14-C2 site, whereas over-expression of PpPPR_45 increased the levels of RNA editing at both the rps14-C2 site and its neighboring C site
Protein Family: Pentatricopeptide repeat (PPR) protein
Subclass: DYW
Physical Interaction: NA
Construct Structure: PLS-E-E+-DYW
Gene ID & Species: PP1S543_6V6 (Physcomitrium patens)
Edited Gene(s): rps14
Editing Type(s): C-to-U (22)
Publication(s): [1] Identification of a pentatricopeptide repeat RNA editing factor in Physcomitrella patens chloroplasts, FEBS Letters, 2014. [doi:10.1016/j.febslet.2014.09.031]
