U2 snRNA (2'-O-methyladenosine-N6)-methyltransferase activity
Catalysis of the reaction: a 2'-O-methyladenosine in U2 snRNA + S-adenosyl-L-methionine = an N6-methyl-2'-O-methyladenosine in U2 snRNA + S-adenosyl-L-homocysteine + H+; methylates the 6th position of adenine residues with a pre-deposited 2'-O-methylation.
