General annotation (Comments)

Function	RNA methyltransferase that methylates tRNAs, and possibly RNA polymerase III transcripts. Methylates cytosine to 5-methylcytosine (m5C) at position 34 of intron-containing tRNA(Leu)(CAA) precursors By similarity.
Catalytic activity	S-adenosyl-L-methionine + tRNA = S-adenosyl-L-homocysteine + tRNA containing 5-methylcytosine.
Subcellular location	Nucleus › nucleolus By similarity. Cytoplasm By similarity.
Sequence similarities	Belongs to the methyltransferase superfamily. RsmB/NOP family. TRM4 subfamily.
