i,次黄嘌呤,腺嘌呤脱氨产物,是鸟嘌呤结构类似物,因此在复制、翻译等过程中,从a到i会导致碱基突变效果
Modifications of RNA affect its function and stability. RNA editing is unique among these modifications because it not only alters the cellular fate of RNA molecules but also alters their sequence relative to the genome. The most common type of RNA editi
Adenosine-to-inosine (A-to-I) RNA editing is a post-transcriptional processing event involved in diversifying the transcriptome responsible for various biological processes. Although bioinformatic approaches have predicted a number of A-to-I editing sites in cDNAs, the human transcriptome is thought to...
inosine is recognized as guanosine (G) by transfer RNA (tRNA). In humans, A-to-I editing predominantly occurs in introns and untranslated regions (UTRs) of protein-coding genes [22], particularly in the 3’UTR, where editing sites are more ...
Despite limited site diversity, we demonstrate that A-to-I RNA editing contributes to proteomic diversity in breast cancer through changes in amino acid sequences. We validate the presence of editing events at both RNA and protein levels. The edited COPA protein increases proliferation, migration, ...

Adenosine-to-inosine (A-to-I) RNA editing is an epigenetic modification catalyzed by adenosine deaminases acting on RNA (ADARs), and is especially prevalent in the brain. We used the highly accurate microfluidics-based multiplex PCR sequencing (mmPCR-seq
In sporadic ALS, RNA editing at the glutamine/arginine site of GluA2 mRNA is specifically reduced in the motor neurons due to the downregulation of adenosine deaminase acting on RNA 2 (ADAR2). Furthermore, TDP-43 pathology, the pathological hallmark of ALS, is observed in the ADAR2-lacking...
A-to-I RNA editing diversifies the transcriptome and has multiple downstream functional effects. Genetic variation contributes to RNA editing variability between individuals and has the potential to impact phenotypic variability. We analyze matched genet
