Predicted to enable tRNA (cytosine-5-)-methyltransferase activity and tRNA binding activity. Predicted to be involved in tRNA C5-cytosine methylation. Predicted to act upstream of or within methylation. Predicted to be located in cytoplasm. Is expressed in several structures, including branchial arch; central nervous system; extraembryonic component; limb bud; and sensory organ. Orthologous to human NSUN6 (NOP2/Sun RNA methyltransferase 6). [provided by Alliance of Genome Resources, Apr 2022]
