CircAI: a comprehensive database of CircRNA associated with A-to-I RNA editing

RNA editing is a prevalent posttranscriptional modification characterized by single-base alterations in RNA transcripts, leading to diverse functional consequences, such as codon changes, mRNA splicing modulation, and regulation of noncoding RNAs, including their binding sites. Although next-generation sequencing has identified over 2 million adenosine-to-inosine (A-to-I) RNA editing sites in mammalian transcriptomes, the functional significance of the majority of these sites, especially those...
