CC -!- FUNCTION: Methyltransferase that adds a 2'-O-methyl group at the 3'-end
CC of piRNAs, a class of 24 to 30 nucleotide RNAs that are generated by a
CC Dicer-independent mechanism and are primarily derived from transposons
CC and other repeated sequence elements. This probably protects the 3'-end
CC of piRNAs from uridylation activity and subsequent degradation.
CC Stabilization of piRNAs is essential for gametogenesis.
CC {ECO:0000250|UniProtKB:Q8CAE2}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=S-adenosyl-L-methionine + small RNA 3'-end nucleotide = H(+) +
CC S-adenosyl-L-homocysteine + small RNA 3'-end 2'-O-methylnucleotide;
CC Xref=Rhea:RHEA:37887, Rhea:RHEA-COMP:10415, Rhea:RHEA-COMP:10416,
CC ChEBI:CHEBI:15378, ChEBI:CHEBI:57856, ChEBI:CHEBI:59789,
CC ChEBI:CHEBI:74896, ChEBI:CHEBI:74898; EC=2.1.1.n8;
CC Evidence={ECO:0000250|UniProtKB:Q8CAE2};
CC -!- COFACTOR:
CC Name=Mg(2+); Xref=ChEBI:CHEBI:18420;
CC Evidence={ECO:0000250|UniProtKB:Q9C5Q8};
CC Note=Binds 1 Mg(2+) ion per subunit. {ECO:0000250|UniProtKB:Q9C5Q8};
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000250|UniProtKB:Q568P9}.
CC Note=Component of the meiotic nuage, also named P granule, a germ-cell-
CC specific organelle required to repress transposon activity during
CC meiosis. {ECO:0000250|UniProtKB:Q568P9}.
CC -!- SIMILARITY: Belongs to the methyltransferase superfamily. HEN1 family.
CC {ECO:0000305}.
