Growing Slowly 1 locus encodes a PLS-type PPR protein required for RNA editing and plant development in Arabidopsis
Most pentatricopeptide repeat (PPR) proteins are involved in organelle post-transcriptional processes, including RNA editing. The PPR proteins include the PLS subfamily, containing characteristic triplets of P, L, and S motifs; however, their editing mechanisms and roles in developmental processes are not fully understood. In this study, we isolated the Arabidopsis thaliana Growing slowly 1 (At...
متن کاملMultiple PPR protein interactions are involved in the RNA editing system in Arabidopsis mitochondria and plastids.
Recent identification of several different types of RNA editing factors in plant organelles suggests complex RNA editosomes within which each factor has a different task. However, the precise protein interactions between the different editing factors are still poorly understood. In this paper, we show that the E+-type pentatricopeptide repeat (PPR) protein SLO2, which lacks a C-terminal cytidin...
متن کاملMitochondrial RNA editing PPR proteins can tolerate protein tags at E as well as at DYW domain termini
INTRODUCTION In plastids and mitochondria of plants, RNA editing changes numerous cytidines to uridines. The nucleotides to be edited are selected by trans-acting proteins which are structurally characterized as pentatricopeptide repeat (PPR) proteins (Kotera et al., 2005; Schmitz-Linneweber and Small, 2008; Takenaka et al., 2013b). The approximately 35 amino acids long elements each attach to ...
متن کاملThe Suppressor of fused gene encodes a novel PEST protein involved in Drosophila segment polarity establishment.
Suppressor of fused, Su(fu), was identified as a semi-dominant suppressor of the putative serine/threonine kinase encoded by the segment polarity gene fused in Drosophila melanogaster. The amorphic Su(fu) mutation is viable, shows a maternal effect and displays no phenotype by itself. Su(fu) mutations are often found associated to karmoisin (kar) mutations but two complementation groups can be ...
متن کاملThe chvH locus of Agrobacterium encodes a homologue of an elongation factor involved in protein synthesis.
The virulence of Agrobacterium tumefaciens depends on both chromosome- and Ti plasmid-encoded gene products. In this study, we characterize a chromosomal locus, chvH, previously identified by TnphoA mutagenesis and shown to be required for tumor formation. Through DNA sequencing and comparison of the sequence with identified sequences in the database, we show that this locus encodes a protein s...
