Predicted to enable protein-lysine N-methyltransferase activity. Predicted to be involved in peptidyl-lysine trimethylation; positive regulation of proton-transporting ATP synthase activity, rotational mechanism; and regulation of mitochondrial ATP synthesis coupled proton transport. Predicted to be located in mitochondrial membrane. Predicted to be integral component of membrane. Predicted to be active in mitochondrion. Orthologous to human ANTKMT (adenine nucleotide translocase lysine methyltransferase). [provided by Alliance of Genome Resources, Apr 2022]
