Predicted to enable several functions, including S-adenosyl-L-methionine binding activity; mRNA (N6-adenosine)-methyltransferase activity; and protein heterodimerization activity. Predicted to be involved in several processes, including RNA metabolic process; gamete generation; and regulation of translation. Predicted to be located in nuclear speck. Predicted to be part of RNA N6-methyladenosine methyltransferase complex. Predicted to be active in nucleus. Orthologous to human METTL3 (methyltransferase 3, N6-adenosine-methyltransferase complex catalytic subunit). [provided by Alliance of Genome Resources, Apr 2022]
