Predicted to enable tRNA (cytosine-5-)-methyltransferase activity. Predicted to be involved in regulation of mitochondrial translation and tRNA wobble base cytosine methylation. Predicted to be located in mitochondrial matrix. Human ortholog(s) of this gene implicated in combined oxidative phosphorylation deficiency 48. Orthologous to human NSUN3 (NOP2/Sun RNA methyltransferase 3). [provided by Alliance of Genome Resources, Apr 2022]
