Changing genetic information through RNA editing.
RNA editing, the post-transcriptional alteration of a gene-encoded sequence, is a widespread phenomenon in eukaryotes. As a consequence of RNA editing, functionally distinct proteins can be produced from a single gene. The molecular mechanisms involved include single or multiple base insertions or deletions as well as base substitutions. In mammals, one type of substitutional RNA editing, chara...
متن کاملRNA Editing RNA
RNA Editing RNA editing is a term used to describe a diverse set of phenomena in which mRNA, rRNA, and tRNA transcripts are modified in sequence after transcription. The types of RNA editing vary from uridine (U) or cytidine (C) insertions and deletions within coding regions of mitochondrial mRNAs to the substitution of specific C residues with U residues in plant mitochondrial mRNAs or the sub...
متن کاملRNA editing.
RNA editing is a term describing a variety of novel mechanisms for the modification of nucleotide sequences of RNA transcripts in different organisms. These editing events include (a) the U-insertion and -deletion type of editing found in the mitochondrion of kinetoplastid protozoa, (b) the C-insertion editing found in the mitochondrion of Physarum, (c) the C-to-U substitution editing of the ma...
متن کاملMolecular diversity through RNA editing: a balancing act.
RNA editing by adenosine deamination fuels the generation of RNA and protein diversity in eukaryotes, particularly in higher organisms. This includes the recoding of translated exons, widespread editing of retrotransposon-derived repeat elements and sequence modification of microRNA (miRNA) transcripts. Such changes can bring about specific amino acid substitutions, alternative splicing and cha...
متن کاملRegulation of Ion Channel and Transporter Function Through RNA Editing.
A large proportion of the recoding events mediated by RNA editing are in mRNAs that encode ion channels and transporters. The effects of these events on protein function have been characterized in only a few cases. In even fewer instances are the mechanistic underpinnings of these effects understood. This review focuses on how RNA editing affects protein function and higher order physiology. In...
