Enables rRNA (adenine-N6-)-methyltransferase activity. Involved in positive regulation of translation; rRNA methylation; and stem cell differentiation. Predicted to be located in nucleus; postsynapse; and presynapse. Human ortholog(s) of this gene implicated in autosomal recessive intellectual developmental disorder-72. Orthologous to human METTL5 (methyltransferase 5, N6-adenosine). [provided by Alliance of Genome Resources, Apr 2022]
