Outline of Final Research Achievements |
Eukaryotic mRNAs and non-coding RNAs contain various post-transcriptional modifications including 5’ cap structure, inosine (I), 5-methylcytidine (m5C), and N6-methyladenosine (m6A). To investigate functional roles of m6A, we screened m6A sites on mRNAs in sporulating budding yeast. More than 8,000 candidate regions were mapped in about 3,000 genes in Saccharomyces cerevisiae by m6A-seq which is a biochemical method to identify m6A regions by immunoprecipitation of m6A-containing RNA fragment by anti-m6A antibody combined with deep sequencing. In addition, we identified a single m6A site in IME1 mRNA by RNA mass spectrometric analysis. However, this m6A site was not confirmed by m6A-seq, exposing a problem of anti-m6A antibody with poor specificity.
