Predicted to be involved in mRNA methylation. Predicted to act upstream of or within tRNA processing. Predicted to be part of tRNA (m1A) methyltransferase complex. Predicted to be active in nucleus. Is expressed in midbrain ventricular layer; olfactory epithelium; submandibular gland primordium; telencephalon ventricular layer; and thymus primordium. Orthologous to human TRMT6 (tRNA methyltransferase 6 non-catalytic subunit). [provided by Alliance of Genome Resources, Apr 2022]
