CC -!- FUNCTION: O-methyltransferase that specifically monomethylates 5'-
CC monophosphate of cytoplasmic histidyl tRNA (tRNA(His)), acting as a
CC capping enzyme by protecting tRNA(His) from cleavage by DICER1. Also
CC able, with less efficiently, to methylate the 5' monophosphate of a
CC subset of pre-miRNAs, acting as a negative regulator of miRNA
CC processing. The 5' monophosphate of pre-miRNAs is recognized by DICER1
CC and is required for pre-miRNAs processing: methylation at this position
CC reduces the processing of pre-miRNAs by DICER1. Was also reported to
CC mediate dimethylation of pre-miR-145; however dimethylation cannot be
CC reproduced by another group which observes a monomethylation of pre-
CC miR-145. {ECO:0000250|UniProtKB:Q7Z5W3}.
