identification of single-nucleotide resolution of cytosine 5-methylation sites in non-coding ribosomal RNAs and transfer RNAs of all three subcellular transcriptomes across six diverse species, overview. The enzyme does not methylate cytosines at structural positions C47, C48, C49 and C72. Identification of modified cytosines in Arabidopsis thaliana nuclear transcribed tRNAs which are dependent on RMTases TRDMT1 and TRM4B. No cytosine 5-methylation sites are detected in Arabidopsis chloroplast or mitochondrial tRNAs, which is in contrast to animal mitochondrial tRNAs |

NSUN2 candidate ncRNA targets identified include RNAs with central functions in the processing, folding and modification of other ncRNAs (RPPH1, Y RNA, SCARNA2), RNAs important for protein synthesis and trafficking (5S rRNA and 7SL RNA) and RNAs involved in multidrug resistance and other processes (Vault RNAs). Notably, all of the NSUN2 targets revealed by 5-azacytidine-mediated RNA immunoprecipitation are either transcribed by RNA Pol III in the nucleolus (SCARNA2 excepted), or function in the nucleolus (SCARNA2), where NSUN2 resides |
