通过腺苷脱氨作用进行的RNA编辑促进了真核生物,特别是高等生物中RNA和蛋白质多样性的产生。这包括翻译的外显子的重新编码,逆转录转座子衍生的重复元件的广泛编辑和miRNA转录物的序列修饰。这种变化可以引起特定的氨基酸取代、选择性剪接和基因表达水平的变化。尽管A-to-I编辑的总体流行率及其对许多受影响基因的特定功能影响尚不清楚,但在时间和空间上平衡RNA修饰水平的重要性正变得越来越明显。特别是,转录组不稳定性的形式太多或太少的RNA编辑活动,或误导编辑表现在几个人类疾病表型,破坏了这种平衡。
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 miRNA transcripts. Such changes can bring about specific amino acid substitutions, alternative splicing and changes in gene expression levels. Although the overall prevalence of A-to-I editing and its specific functional impact on many of the affected genes are not yet known, the importance of balancing RNA modification levels across time and space is becoming increasingly evident. In particular, transcriptome instabilities in form of too much or too little RNA editing activity, or misguided editing manifest in several human disease phenotypes which disrupt that balance.
