Predicted to enable rRNA (cytosine-C5-)-methyltransferase activity. Predicted to be involved in several processes, including central nervous system development; rRNA base methylation; and regulation of myelination. Predicted to be located in nucleoplasm. Predicted to be active in nucleolus. Orthologous to human NSUN5 (NOP2/Sun RNA methyltransferase 5). [provided by Alliance of Genome Resources, Apr 2022]
