Ltter In Search of Beneficial Coding RNA Editing
RNA editing is a posttranscriptional modification that can lead to a change in the encoded protein sequence of a gene. Although a few cases of mammalian coding RNA editing are known to be functionally important, the vast majority of over 2,000 A-to-I editing sites that have been identified from the coding regions of the human genome are likely nonadaptive, representing tolerable promiscuous tar...
متن کاملHuman coding RNA editing is generally nonadaptive.
Impairment of RNA editing at a handful of coding sites causes severe disorders, prompting the view that coding RNA editing is highly advantageous. Recent genomic studies have expanded the list of human coding RNA editing sites by more than 100 times, raising the question of how common advantageous RNA editing is. Analyzing 1,783 human coding A-to-G editing sites, we show that both the frequency...
متن کاملUncovering RNA Editing Sites in Long Non-Coding RNAs
RNA editing is an important co/post-transcriptional molecular process able to modify RNAs by nucleotide insertions/deletions or substitutions. In human, the most common RNA editing event involves the deamination of adenosine (A) into inosine (I) through the adenosine deaminase acting on RNA proteins. Although A-to-I editing can occur in both coding and non-coding RNAs, recent findings, based on...
متن کاملSOX2OT, a long non-coding RNA involved in autophagy regulation
Summary: SOX2 overlapping transcript (SOX2OT) is a long non-coding RNA associated with cancer pathogenesis. It contributes to a variety of cellular functions and recent evidence propounds its association with autophagy process. It has been showed that SOX2OT can regulate the expression of different autophagy associated factors in human cells with different mechanisms, however more remains to ...
متن کاملHuman C-to-U Coding RNA Editing Is Largely Nonadaptive.
C-to-U RNA editing enzymatically converts the base C to U in RNA molecules and could lead to nonsynonymous changes when occurring in coding regions. Hundreds to thousands of coding sites were recently found to be C-to-U edited or editable in humans, but the biological significance of this phenomenon is elusive. Here, we test the prevailing hypothesis that nonsynonymous editing is beneficial bec...
