Predicted to enable heat shock protein binding activity and protein-lysine N-methyltransferase activity. Predicted to be involved in peptidyl-lysine trimethylation. Predicted to act upstream of or within cellular response to hormone stimulus; regulation of release of sequestered calcium ion into cytosol by sarcoplasmic reticulum; and skeletal muscle tissue development. Predicted to be located in nucleus. Predicted to be part of protein-containing complex. Predicted to be active in cytosol. Orthologous to human METTL21C (methyltransferase 21C, AARS1 lysine).
