NSUN2 is an RNA cytosine C5-methyltransferase that methylates cytosine to 5-methylcytosine in various RNAs, such as tRNAs, mRNAs and some long non-coding RNAs [1,2]. Trm4 is capable of methylating cytosine to m5C at several positions in different yeast tRNAs and pre-tRNAs containing intron [3]. This domain has a detectable similarity to known PUA domains and it is predicted to adopt similar structure.
