molecular function
    GO:0008171    O-methyltransferase activity    Catalysis of the transfer of a methyl group to the oxygen atom of an acceptor molecule.
    GO:0008173    RNA methyltransferase activity    Catalysis of the transfer of a methyl group from a donor to a nucleoside residue in an RNA molecule.
    GO:0008168    methyltransferase activity    Catalysis of the transfer of a methyl group to an acceptor molecule.
    GO:0016740    transferase activity    Catalysis of the transfer of a group, e.g. a methyl group, glycosyl group, acyl group, phosphorus-containing, or other groups, from one compound (generally regarded as the donor) to another compound (generally regarded as the acceptor). Transferase is the systematic name for any enzyme of EC class 2.
biological process
    GO:0001510    RNA methylation    Posttranscriptional addition of a methyl group to either a nucleotide or 2'-O ribose in a polyribonucleotide. Usually uses S-adenosylmethionine as a cofactor.
    GO:0032259    methylation    The process in which a methyl group is covalently attached to a molecule.
