Improved Computational Target Site Prediction for Pentatricopeptide Repeat RNA Editing Factors
Pentatricopeptide repeat (PPR) proteins with an E domain have been identified as specific factors for C to U RNA editing in plant organelles. These PPR proteins bind to a unique sequence motif 5' of their target editing sites. Recently, involvement of a combinatorial amino acid code in the P (normal length) and S type (short) PPR domains in sequence specific RNA binding was reported. PPR protei...
متن کاملChloroplast RNA editing by pentatricopeptide repeat proteins.
Pentatricopeptide repeat (PPR) proteins function in multiple processes in mRNA maturation in plastids and mitochondria (reviewed in Schmitz-Linneweber and Small, 2008). RNA maturation in chloroplasts is complex, and PPR proteins act in cisand trans-splicing, translation, RNA cleavage, RNA stabilization, and RNA editing. This large protein family, with 450 members in Arabidopsis, is characterize...
متن کاملChloroplast RNA-binding and pentatricopeptide repeat proteins.
Chloroplast gene expression is mainly regulated at the post-transcriptional level by numerous nuclear-encoded RNA-binding protein factors. In the present study, we focus on two RNA-binding proteins: cpRNP (chloroplast ribonucleoprotein) and PPR (pentatricopeptide repeat) protein. These are suggested to be major contributors to chloroplast RNA metabolism. Tobacco cpRNPs are composed of five diff...
متن کاملaPPRove: An HMM-Based Method for Accurate Prediction of RNA-Pentatricopeptide Repeat Protein Binding Events
Pentatricopeptide repeat containing proteins (PPRs) bind to RNA transcripts originating from mitochondria and plastids. There are two classes of PPR proteins. The [Formula: see text] class contains tandem [Formula: see text]-type motif sequences, and the [Formula: see text] class contains alternating [Formula: see text], [Formula: see text] and [Formula: see text] type sequences. In this paper,...
متن کاملPentatricopeptide repeat proteins involved in plant organellar RNA editing
C-to-U RNA editing has been widely observed in organellar RNAs in terrestrial plants. Recent research has revealed the significance of a large, plant-specific family of pentatricopeptide repeat (PPR) proteins for RNA editing and other RNA processing events in plant mitochondria and chloroplasts. PPR protein is a sequence-specific RNA-binding protein that identifies specific C residues for editi...
