EMB2261 - Plant Editosome Database - BIG Data Center

Summary

Editing Factor: EMB2261
Synonym: ECD1; EMBRYO DEFECTIVE 2261
Description: The emb2261-2 mutation is lethal through a failure to express an editing factor that specifically recognizes the rps14-2 site; EMB2261 was predicted to bind the cis-element upstream of the rps14-2 site and genetic complementation with promoters of different strength followed by RNA-seq analysis was conducted to test the correlation between rps14-2 editing and EMB2261 expression; Rps14-2 is the only editing event in Arabidopsis chloroplasts that correlates with EMB2261 expression; Sequence divergence between the cis-element and the EMB2261 protein sequence in plants where rps14-2 editing is not required adds support to the association between them
