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 Involved in the pre-rRNA processing steps leading to small-subunit rRNA
CC production independently of its RNA-modifying catalytic activity. Part
CC of the small subunit (SSU) processome, first precursor of the small
CC eukaryotic ribosomal subunit. During the assembly of the SSU processome
CC in the nucleolus, many ribosome biogenesis factors, an RNA chaperone
CC and ribosomal proteins associate with the nascent pre-rRNA and work in
CC concert to generate RNA folding, modifications, rearrangements and
CC cleavage as well as targeted degradation of pre-ribosomal RNA by the
CC RNA exosome. {ECO:0000250|UniProtKB:Q9UNQ2}.
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,
CC ChEBI:CHEBI:15378, ChEBI:CHEBI:57856, ChEBI:CHEBI:59789,
CC ChEBI:CHEBI:74411, ChEBI:CHEBI:74493; EC=2.1.1.183;
CC Evidence={ECO:0000250|UniProtKB:Q9UNQ2};
CC -!- SUBUNIT: Part of the small subunit (SSU) processome, composed of more
CC than 70 proteins and the RNA chaperone small nucleolar RNA (snoRNA) U3.
CC {ECO:0000250|UniProtKB:Q9UNQ2}.
CC -!- SUBCELLULAR LOCATION: Nucleus, nucleoplasm
CC {ECO:0000250|UniProtKB:Q9UNQ2}. Nucleus, nucleolus
CC {ECO:0000250|UniProtKB:Q9UNQ2}.
CC -!- SIMILARITY: Belongs to the class I-like SAM-binding methyltransferase
CC superfamily. rRNA adenine N(6)-methyltransferase family.
CC {ECO:0000255|PROSITE-ProRule:PRU01026}.
CC -!- SEQUENCE CAUTION:
CC Sequence=BAC37166.1; Type=Miscellaneous discrepancy; Note=Introns retention.; Evidence={ECO:0000305};
