CC -!- FUNCTION: Specifically dimethylates two adjacent adenosines in the loop
CC of a conserved hairpin near the 3'-end of 18S rRNA in the 40S particle.
CC {ECO:0000256|ARBA:ARBA00002977}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=adenosine(1779)/adenosine(1780) in 18S rRNA + 4 S-adenosyl-L-
CC methionine = 4 H(+) + N(6)-dimethyladenosine(1779)/N(6)-
CC dimethyladenosine(1780) in 18S rRNA + 4 S-adenosyl-L-homocysteine;
CC Xref=Rhea:RHEA:42780, Rhea:RHEA-COMP:10234, Rhea:RHEA-COMP:10236,
